About Me

I'm a Backend Software Engineer with hands-on experience building ERP and CRM systems for pharmaceutical clients, contributing to open-source ASP.NET Core projects, and delivering APIs used in live mobile and web applications. Currently at Premium Card, I develop backend services for financial systems and mobile applications using ASP.NET Core and SQL Server.

Previously at SBS (Simple Brilliant Solution), I built and maintained a .NET Core CRM/ERP system serving 200+ pharmaceutical organizations, improving SQL query performance by 20–30% across reporting modules.

I graduated with a Bachelor's in Computer Science from October 6 University (Very Good). My graduation project, an AI-powered fitness tracking application, received an A+ grade. Beyond professional work, I'm involved in competitive programming, having completed advanced training at Coach Academy and O6U ICPC Community.
