What I'm looking for

I seek roles building end-to-end web or mobile products with strong testing and cloud practices, collaborative teams, and growth opportunities.

I am a Full Stack Developer with experience building web and mobile applications using Django, Node.js, React, Angular, and Flutter, plus cloud and database integrations. I have designed and implemented scalable backends, REST and GraphQL APIs, data visualization interfaces, and automated ETL and serverless pipelines.

My work spans enterprise and startup environments where I delivered multiple production applications, introduced front-end testing practices, and integrated cloud services (AWS, Azure, Heroku). I prioritize robust testing, maintainable architectures, and practical UX to solve real user problems.
