I’m ready to strengthen my data-analytics toolkit and would like a dedicated trainer who can guide me step-by-step, starting with SQL. My immediate goal is to master basic queries and commands—writing SELECT statements, filtering, ordering, joining tables, and understanding how these fundamentals translate into everyday analytical tasks. Once that foundation is solid, we’ll move on to Tableau for visualisation and finally touch on automation techniques that tie everything together. Live, interactive sessions with hands-on exercises are ideal because I learn fastest by doing and receiving real-time feedback. Recordings or written recaps after each lesson would be a plus so I can review between meetings. Please highlight your experience teaching SQL to beginners (particul...
I’m refreshing the “Data Entry Projects” section of my website and need several brand-new examples that showcase manual data input work specifically within the education sector. I’m not looking to tweak my existing copy or redesign the page—what I need are completely new, well-written project snapshots that demonstrate the breadth and value of this service for schools, universities, training providers, and similar organisations. Here’s what I’m after: • 3–5 concise case-style write-ups (150–200 words each) that describe the client situation, the manual data entry task, the tools or platforms used (Excel, Google Sheets, CRM systems, LMS uploads, etc.), and the measurable outcome. • A short headline for each example plus one...

Our SaaS platform is already live, but I want a seasoned React / and Node.js developer to give it a rigorous technical once-over so we can scale with confidence. The immediate focus is a full codebase and architectural review, making sure every module is clean, maintainable, and truly production-ready. Performance is the headline goal. Please profile and tune the areas that matter most to us: dashboard load time, API response time, and the heavier database queries that power our charts. I expect concrete, measurable gains—think quicker Time to First Byte, lower p95 latencies, and smoother UI interactions—without sacrificing code clarity. While you are in the weeds, scrutinise the onboarding flow that starts with a user’s API token and ends with an activated account. An...
Project Requirements Summary I am seeking a professional development team or agency to design and build a full-scale professional networking platform similar to LinkedIn. The platform should be custom-developed from scratch with full source code ownership and intellectual property rights transferred to me upon completion. The system must be built with scalable architecture capable of supporting large user growth, incorporating core features such as professional user profiles, networking connections, job postings, recruitment tools, content publishing, private messaging, and administrative management dashboards. Security, performance, and data protection must follow modern industry standards, including secure authentication, encryption, and infrastructure readiness for cloud deployment. ...
I need a clear, descriptive look at past inventory activity captured in our Oracle ERP system. The goal is a concise summary report that tells me, at a glance, how stock levels have moved, where turnover is strong or weak, and which items or locations stand out as anomalies. You will extract the relevant inventory tables (or work with a CSV extract I provide), shape the data with SQL or any preferred ETL approach, and present the findings in an executive-friendly format. Accuracy and interpretability are more important than advanced forecasting; this is strictly descriptive analysis. Core deliverables • Cleaned and consolidated dataset of historical inventory transactions • Executive summary report highlighting key metrics (stock movement, average holding days, turnover, no...

I need my Open Journal Systems instance taken from version 3.3 to 3.5.0.3. Alongside the version bump I would like a few fresh interface touches—think new blocks, buttons or info panels that help editors access key tools faster. Existing workflows and plugins can stay as they are as long as the upgrade itself runs smoothly; small visual shifts are welcome if they come with the new elements we add. Here is what I have in mind: • Full files-and-database backup before you touch anything. • Clean upgrade to 3.5.0.3 with all standard post-upgrade checks (DB migrations, plugin compatibility, email templates). • Final verification that submission, review and publishing still work end-to-end. Please bring solid OJS experience, comfort with PHP, SQL and the Smarty/Boot...
I run a Counter-Strike 2 dedicated server on Ubuntu (current LTS) and need HLstatsX:CE installed from scratch and tuned so it starts collecting live data straight away. The box already hosts Nginx, so the web front-end must sit behind that existing stack—preferably on a clean sub-domain—with SSL kept intact. All core pieces have to talk to each other: game server ↔ log-daemon ↔ MySQL/MariaDB ↔ web interface. Please handle every dependency, create the database, adjust any firewall rules, and finish by restarting the CS2 instance with the correct launch parameters so stats instantly populate. Acceptance will be based on: • Public stats page loading through Nginx with no errors • Real-time player data appearing after a live match • Clear, ...
I need an IBM Infosphere MDM specialist who can take ownership of our data-integration layer and help me raise accuracy and consistency across the platform. The engagement is fully remote but you must sit somewhere in Europe so we can work within a comfortable time-zone overlap; fluent English is essential for day-to-day collaboration. My priority is Data Integration. Multiple operational databases, several cloud services and a growing set of partner-facing APIs all need to flow cleanly into the MDM hub. I already have core MDM services online, yet duplicate records and mismatched attributes keep creeping in. Your job is to analyse the current ingestion routes, design (or redesign) the mappings, and configure the Infosphere components—Integration Hub, DataStage, QualityStage, or a...
I need an SAP DMS specialist who can set up a robust, real-time data-synchronisation link between SAP DMS and my existing EDMS platform. The single objective is to keep documents and their file versions perfectly mirrored in both environments so that users never wonder which system holds the latest copy. You will analyse the current SAP DMS configuration, study the API or connector options offered by the EDMS, and then design and build the integration—whether that means ABAP exits, BAPIs, RFCs, SAP PI/PO, Cloud Integration, REST, or another proven method. Reliability and error handling come first; I want automatic retries and clear logging so we can trace every document that moves. Once the interface is in place, I expect: • End-to-end testing that shows new, updated, and del...
(Solo perfiles con experiencia demostrable en diseño de esquemas PostgreSQL en producción. No busco desarrollo web, sino arquitectura y consistencia relacional.) Tengo una base de datos PostgreSQL alojada en Supabase que recoge partidos, goles, tarjetas, convocatorias, sustituciones y más. Ya está conectada a Power BI y funciona, pero quiero garantizar su integridad antes de seguir creciendo. Lo que necesito • Revisar el esquema actual y unificar los tipos de clave (codigo_equipo, codigo_jugador, codigo_acta). • Definir y aplicar PK, UK, FK e índices que mejoren consistencia y tiempos de consulta. • Detectar registros duplicados y proponer claves naturales para cada tipo de evento. • Renombrar o re-codificar columnas problem&aa...
Necesito diseñar e implementar una base de datos que centralice la información de producción, clientes e inventario de mi negocio. Todavía no he decidido si conviene un modelo relacional (SQL) o no relacional (NoSQL), así que valoro tu recomendación según escalabilidad, costo y facilidad de mantenimiento. Alcance que tengo en mente: • Modelado del esquema para datos de producción, clientes e inventarios, asegurando integridad y relaciones claras. • Funciones básicas de consulta y reporte: totales de producción por periodo, niveles de stock en tiempo real y resumen de clientes activos. • Documentación breve que detalle la estructura, credenciales genéricas, instrucciones de respaldo y c&oa...
I’m building an internal security tool and need a solid PostgreSQL foundation that starts as a single, multi-tenant database yet can be cleanly split into separate databases—and separate servers—later on. The first release will concentrate on storing architectural components (a very well defined structure) alongside threat-intelligence data (mapped to the components metadata), so the schema must keep cross-tenant isolation strict while still allowing swift relational join matching across those two domains. What I need from you • A full relational schema (ERD and DDL) optimised for multi-tenant operation—think shared-table with isolated tenant-id or schema-per-tenant, whichever you can justify—and documented so the eventual extraction path is clear. &...

The goal is to design a future-proof relational backbone for a multi-channel retail platform, built natively on PostgreSQL. I already run an operational system, and its live transactional records will have to be migrated into the new structure without downtime. Everything else—users, inventory, orders—will start fresh. Core design expectations The operational schema should be fully normalised to 3NF and optimised from day one for high concurrency. Think table partitioning (range and list), well-chosen GIN and B-Tree indexes, plus JSONB columns where semi-structured flexibility makes sense. Triggers, constraints and stored procedures must enforce business logic consistently, so the application tier can stay lightweight. Analytics layer Alongside the OLTP schema I need a se...

I keep seeing high RAM utilisation on both Oracle Linux and Red Hat Enterprise Linux servers and I want to understand, in depth, what is really happening inside the memory subsystem. More than a quick fix, I need a knowledgeable administrator who can walk me through each layer—kernel, user space, buffers, cache, swap—so I can read the numbers with confidence and spot the true culprits when usage spikes. Here is what I expect from our collaboration: • A live, step-by-step session (or series) where we run commands such as free, top, vmstat, sar and others you recommend, interpret every column, and relate the output to the kernel’s behaviour. • Practical explanations of how Oracle Linux and RHEL may differ in their memory reporting and tuning parameters. &bull...
I need an experienced Comfy specialist to take us from a blank server to a fully functioning environment my team can rely on every day. The first priority is a clean installation and initial configuration: database, user roles, security settings, and any recommended performance tweaks. Once it is running smoothly, I’d like you to walk us through the platform’s more advanced, custom-feature workflow so we can tailor it to our internal processes. We have not yet decided whether the platform will need to hook into other tools, so I’ll look to you for advice on what’s possible and the best timing for any integrations. After setup, please deliver an advanced training session (remote is fine) that demonstrates how to extend or adjust those custom features, plus written ...
Hi! I am looking to upgrade my current sales dashboard. I am looking for a Data Specialist who I can learn from and who can propose the best solution for my needs. Data will come from CSV files. I need a place where I can import that data to. I would like the dashboard to be as detailed as possible showing multiple KPIs, graphs, and correlations between the various data. Once setup, I would like it to be fairly simple to import new data, and modify the dashboard as needed over time. I would like this setup to be fully offline and local. My current thoughts are Metabase + SQLite. However I am open to other solutions and recommendations. I will be able to provide an example of the CSV during discussion to see how and what we can achieve with the data. I am looking for an individual who...

I need an experienced Microsoft Fabric administrator to keep several workspaces healthy and up-to-date. The core of the engagement is ongoing general maintenance, with three recurring duties at its heart: • Regular backups of every workspace, stored securely and verified for integrity • Security checks that review permissions, access policies, and audit logs • Version updates to ensure we are running the latest stable features without disrupting service If you can also lend a hand with occasional troubleshooting or performance tuning when it makes sense, that would be a welcome bonus, but the immediate priority is the steady rhythm of maintenance tasks above. Please outline the process and tooling you normally use for Fabric backups, security hardening, and update...
I’m setting up a central repository where each of my subscribed clients—schools, companies, public bodies and similar organisations—can log in over the internet to view, upload and download their own estate-related and compliance documents such as surveys, inspection reports and certificates. Editing in the browser isn’t required; the goal is a “read, upload, download” portal that keeps every file in its original form. Here’s what I need built: • A relational database (SQL or comparable) that stores the file-metadata and user accounts. • A clean web interface that works on desktop and mobile, served from my own on-prem server. • Username-and-password authentication with session timeout and password-reset functions. • Rol...
We are looking for ongoing, reliable in-house IT and administrative support to keep our small but diverse internal environment running smoothly. This is a hands-on role supporting staff and systems day to day. Most of our stack is out-of-the-box software, complemented by custom in-house software and applications that support how we work. The work is varied and practical. One week you might be contributing to a project to improve or streamline existing systems; the next you could be onboarding new staff, troubleshooting a line-of-business application, assisting with configuration issues, or handling general administrative tasks that support the wider team. There is also an element of research and information gathering for internal projects, such as evaluating tools, documenting opti...
