What I'm looking for

I seek roles building robust, secure backend and full-stack systems with clear deployment pipelines, collaborative teams, and opportunities to modernize legacy systems and improve operational efficiency.

I am a full-stack .NET engineer with experience building secure fintech applications, enterprise automation solutions, and modernized legacy systems. I have delivered end-to-end projects—from requirements and bottleneck identification through design, development, and deployment—reducing manual work and improving system efficiency.

My background includes C#/.NET, RESTful API design, MS SQL optimization, Azure DevOps pipelines, and implementing security best practices (OWASP, CompTIA Security+). I focus on clean architecture, testing, and maintainable code while collaborating cross-functionally to integrate software with existing infrastructure and scale high-volume systems.
