Message

At Omnix Solutions, I develop and maintain business-critical web applications using C#/.NET, Angular, TypeScript, JavaScript, and SQL Server. My work includes REST APIs and integrations between systems.

I work extensively with SQL Server, writing complex queries and views, creating reports, and handling data validation and business rules. I also investigate and resolve production incidents across applications, databases, integrations, and infrastructure.

Previously, I developed mobile and web applications at TK. Marketing Inc using Flutter and Dart, with API and Firebase integrations and interfaces based on Figma. At Ollypop, I developed and maintained the brand’s Next.js website and supported e-commerce operations.
