What I'm looking for

I’m looking for a team in Agile environments where I can build secure, maintainable full-stack systems and cloud-native microservices, improve performance and reliability, and apply Large Language Models to real, production-ready applications.

I’m a Senior Full Stack Engineer with 7+ years of experience designing and delivering scalable web applications, cloud-native microservices, and API-driven platforms for healthcare, financial services, and enterprise clients. I focus on clean, maintainable engineering—writing secure solutions with Python and modern backend/API frameworks, while staying pragmatic about performance and reliability.

In my recent role, I collaborated with cross-functional teams to build full-stack applications using FastAPI, Django, Django REST Framework, React, Next.js, and TypeScript, improving maintainability and performance through query optimization and Redis caching. I’ve also streamlined deployments with Docker, Kubernetes, AWS services, Terraform, and CI/CD, and strengthened quality with Pytest, code reviews, and observability using Prometheus, Grafana, and the ELK Stack—along with work on AI-powered applications using Large Language Models.
