Thousands of lines of T-SQL that once worked are now returning incorrect results. I need a fresh set of expert eyes to comb through the entire script, pinpoint exactly where the logic breaks down, and fix it. The code lives in SQL Server. While you work through the main script, I also need you to cascade several hundred new parameters into a series of dependent stored procedures. These procedures already compile; they simply require the additional parameters to be wired through correctly so downstream calculations stay consistent. What I expect from you: • A clean, corrected version of the original query and any touched procedures • A concise change log explaining the root cause of the logical error and how you resolved it • Updated stored procedures with...

Data will come from our existing production sheets; I can supply CSV exports or connect you to our SQL server—whatever you prefer. Once the model is in place, I’ll look for simple ways to refresh it (Gateway, scheduled refresh, or other). Acceptance criteria – Line-wise pieces produced, efficiency %, and quality rate in one interactive view – Daily snapshot plus week-to-date and month-to-date filters that perform quickly – Responsive lay...
...but the payment step can stop at a confirmation screen—no real gateway hookup for now. • Basic database layer to store products and capture mock orders so I can review them in an admin view or via simple SQL queries. • Clean code structure that I can later extend into a full production build. Tech is flexible—React, Vue, or a templated PHP/Node stack all work for me as long as the final site loads quickly and is easy to maintain. I’m open to your preferred framework and any boilerplate you’ve proven on past jobs. Deliverables 1. Source code with clear README for local setup. 2. SQL export or migration scripts for sample data. 3. Deployed demo link (Heroku, Vercel, shared cPanel, etc.) I can click through. 4. Short hand-off call...

...a robust preprocessing pipeline that feeds seamlessly into our future predictive models. The end-goal for this phase is clear: extract insights that help us validate product hypotheses and impress early pilot partners. We move fast—ASAP delivery is non-negotiable—so I’m looking for someone who can jump in, spin up notebooks, and iterate daily. Expect to work with Python (Pandas, NumPy, SciPy), SQL, and ideally Spark for the heavier ETL steps; experience deploying workflows on AWS or GCP is a plus because we’ll be productionising soon. Deliverables • Cleaned, well-documented datasets ready for downstream modelling • A reproducible preprocessing pipeline (scripts or notebooks + environment files) • An insights report highlighting key t...
...would be: “Show me the growth in March vs February” or “Which categories were above average last quarter?” The bot should reply with concise text explanations plus optional charts or tables, ready for copying into reports or dashboards. Data will arrive in CSV or through a direct connection to our existing store platform; the solution should comfortably handle either method. Python with pandas, SQL, or a similar stack is fine as long as the response time stays near real-time. Feel free to integrate an LLM or retrieval-augmented generation layer so the conversation feels natural and follow-up questions are understood in context. Deliverables • A working chatbot deployed to a simple web interface or Slack channel • Source code and environment...

...layer designed around a hybrid model—relational tables for structured, transactional data alongside a NoSQL store for high-volume or schemaless collections—so familiarity with both SQL (PostgreSQL or MySQL) and something like MongoDB, DynamoDB, or Firestore is essential. I already have product requirements mapped out; what I need from you is: • A scalable architecture diagram showing tenancy isolation, shared services, and CI/CD flow • Implementation of the core multi-tenant framework (user provisioning, tenant onboarding, permission engine, billing hooks) • Database schemas and migration scripts for the SQL side, plus collections and indexing strategy for the NoSQL side • Containerised deployment (Docker / Kubernetes or similar) wit...
The page at suddenly refuses to reach my MySQL database. Instead of a clear SQL error, it simply “does not connect,” leaving the form unusable. I have not touched the username, password, host, or database name, and I have yet to test other scripts on the same server. I need you to: • Inspect the existing PHP connection logic on (and any included config files) • Identify why the connection fails and correct it so the page inserts data again • Document the exact fix you apply so I can replicate it elsewhere if needed Please be comfortable troubleshooting classic PHP-MySQLi (or PDO) code, checking server logs, and confirming that the final page loads without warnings or notices. Once your fix is in place, I’ll verify the form submits successfu...

...a project-style gallery or dashboard that showcases trading instruments in real time, and a Contact form so users can reach support without leaving the page. The front end has to be modern, fast and responsive—React, Vue, Svelte or a similar framework is fine as long as it renders smoothly on desktop and mobile browsers. For the back end, I lean toward Node.js/Express or Python/Django with a SQL or NoSQL database to store user profiles, order history and configuration data. Real-time market quotes should stream through WebSockets from a third-party API, and every sensitive request must pass through HTTPS with the usual encryption, rate-limiting and input validation in place. I will consider the job complete when the source code is delivered, runs error-free on my VPS ...
...betting platform and want a qualified ethical hacker to run a full-scale penetration test against the public-facing web application. The priority is website & application-level weaknesses, so I expect you to probe everything users can touch: signup, log-in, wallets, odds display, live bets, admin panels behind authentication—every feature that might be exploited. Please include the usual suspects—SQL injection, XSS, CSRF, IDOR, authentication bypass, file upload issues, business-logic flaws—essentially the OWASP Top 10 and anything else you uncover during your manual and automated reconnaissance. Black-box testing is preferred at first; if you later need limited credentials for deeper inspection we can arrange that. Deliverables I need: • A concise ex...

I have a SQL Server view that already aggregates every validation script we run on raw_valid and model_valid. What I now need is the front-end: an interactive Power BI dashboard built in a tabbed interface that surfaces those scripts, lets users explore them, and provides both basic text search and advanced filtering. Connection & data model • Connect directly to the existing view (read-only). • Expose the script name, object type, target table, last run date, status, and the full script body or a hyperlink to it. • Optimise the model so the dashboard opens quickly even when the view grows. Visual & navigation requirements • Two main tabs—one for raw_valid scripts, one for model_valid—each mirroring the same layout for consis...
