Product Manager & Lead .NET Developer

Career Summary

Lead .NET developer and product owner with 15+ years building enterprise ERP and line-of-business systems. Currently working as part of the team on the rewrite of a retail company's core ERP — 8,000 users across 180+ branches — from a legacy FoxPro Windows application into a Modular Monolith on Blazor Server (.NET 10), Entity Framework Core and SQL Server. Founder of SahaERP, an open-source .NET 10 / PostgreSQL / React ERP for Turkish SMEs. Areas of depth: T-SQL and EF Core query optimization, Blazor Server architecture, and complex domain modeling (financial workflows, multi-branch authorization, manufacturing routing). I run my own production Linux infrastructure on Hetzner — Docker, Nginx (TLS, reverse proxy), DNS (SPF/DKIM/DMARC), self-hosted Stalwart mail, Tailscale — and bring that operational perspective to how I design systems. Trilingual: Arabic, Turkish, English.
