MS Access | VBA | SQL Server | MySQL | Business Automation Specialist | SharePoint Specialist
I help businesses automate operations, reporting, and internal workflows using MS Access, Python, VBA, MySQL and SQL Server.
With 15+ years of experience and 12,000+ Upwork hours, I design structured database systems that replace spreadsheets, eliminate manual errors, and improve reporting efficiency.
What I Specialize In:
✔ Full database architecture (from concept, Excel mockup, or redesign)
✔ Relational database modeling & normalization
✔ Multi-user Access systems (LAN / SharePoint / SQL Server backend)
✔ Role-based login & user-level permissions
✔ Advanced VBA automation
✔ Performance optimization & database repair
✔ Excel / CSV import-export automation
✔ Analytical dashboards & dynamic reporting
✔ SQL query development & reporting logic
My Approach:
Many Access databases become unstable over time due to:
Poor structure
Unoptimized queries
Weak VBA organization
Lack of scalability planning
I focus on long-term maintainability, performance, and clean architecture.
If you need a professional MS Access system that works reliably for years — I can help.
