Mohammad Khorshidi

Full-stack web developer and IT specialist with 20+ years of experience building and supporting business systems. I develop complete web applications using ASP.NET (C#) and React/Next.js, backed by SQL Server, Oracle, and MongoDB. I've delivered production systems for transportation, payroll, and pharmaceutical inventory clients, including a full-stack furnace department app (ASP.NET + React + SQL Server) for Simatən Co.

Services: full-stack web development, frontend (React, Next.js, JavaScript), backend APIs (C#, ASP.NET, Python), database design and optimization (SQL Server, Oracle PL/SQL, MongoDB), legacy system modernization (FoxPro, VBA), automation scripting (VBA, Python), and data analytics (Python, R, SAS, Tableau, Excel).

I also bring strong infrastructure skills — Windows Server, Active Directory, IIS, networking (CCNA, CompTIA Network+) — so your app is deployable and secure, not just coded. Certified Data Science Architect (2025). Fluent English and Persian. Available for fixed-price, hourly, and long-term projects. I scope clearly, deliver in reviewable increments, and provide clean code with documentation and ongoing support.
