Hello Friend !
You don't have to worry about this HRMS Software development over windows, it's totally fine PHP frontend and SQL Server back-end. One of my clients from Hongkong had similar application.
We can do a 15-minute free call to discuss the project requirements and our work plan.
On 1st Jan 2023, I requested Microsoft for a feature improvement, which was accepted by Bob Ward, Principal Architect at Microsoft.
Feature Improvement Request: 201 Buckets Problem, Histograms & Single 8KB Page Limitation, Statistics in SQL Server.
I have 7+ years of exceptional knowledge and experience in high performance OLTP systems (Microsoft SQL Server).
Please feel free to ask for adjustment if my Bid Amount or Hourly Rate does not suit your budget.
Warm regards,
Kundan Bihari ( SQL Server Consultant )
