I’m a Python backend developer who builds FastAPI-based microservices and REST APIs on AWS, with a strong focus on performance, reliability, and maintainable engineering practices. At Tata Consultancy Services, I optimized a critical pharma-sector backend by 30–40% using Python refactoring, AWS (EC2, S3, Lambda) infrastructure tuning, and automated CI/CD pipelines—cutting latency and improving production reliability.

I also helped raise the engineering bar across teams by authoring a company-wide Python Engineering Style Guide, which standardized code quality and improved onboarding and collaboration for distributed teams. I built and maintained GitHub Actions CI/CD pipelines with Git workflows for a 10+ person cross-functional group, and as Agile Champion I facilitated sprint planning, backlog grooming, and retrospectives while producing sprint velocity dashboards and KPI reports for senior leadership.

Earlier, as a Backend Developer Intern, I redesigned microservices REST API architecture with FastAPI and async programming to increase DAU by 30% and reduce drop-off by 25%, and I engineered high-performance endpoints that improved response times by 25–50% in production. I’ve continued this work through projects like a real-time Auction House Platform (FastAPI + PostgreSQL + WebSockets on AWS) and my B.E. thesis, Secure Collage Space, which used FastAPI with facial recognition (OpenCV) and OTP authentication via REST APIs.
