What I'm looking for

I seek full-stack or backend roles focused on scalable web applications, performance optimization, cloud deployments, and collaborative teams that value clean architecture and growth.

I am a full-stack engineer with 4+ years building scalable web applications emphasizing clean architecture, performance and positive end-user experiences. I specialize in Python backend development with FastAPI and SQL databases and build responsive front ends using NextJS and VueJS.

At Gravitas Toll Solutions I designed and developed a full-stack platform, improved data processing speed by 50% through batching and parallelism, and containerized services with Docker. I also implemented data extraction pipelines using pdfplumber and Pandas, and integrated payment and chatbot solutions earlier in my career.

I value collaborative development workflows, automated deployments and pragmatic problem solving. I bring a strong foundation in REST APIs, performance optimization, cloud-ready deployments and a commitment to maintainable, testable code.
