What I'm looking for

I seek senior engineering roles where I can build scalable full-stack systems, lead teams, modernize architecture, and apply cloud, CI/CD, and ML integrations.

I am a Senior Full-Stack Engineer with 11+ years designing, developing, and deploying scalable applications using C#/.NET, Node.js, NestJS, and modern JavaScript frameworks.

I have led backend modernization and microservice initiatives, reduced latency up to 45%, and optimized databases to improve API response times and frontend performance.

I build performant frontend experiences with React.js, Next.js, Angular, component-driven architecture, and reusable UI systems while establishing CI/CD pipelines and cloud infrastructure on AWS and Azure.

I mentor engineers, drive TDD and Agile practices, integrate ML and GPT APIs for automation and analytics, and focus on delivering measurable business value through maintainable architecture.
