What I'm looking for

I’m looking for a team that values ownership, production-grade engineering, and fast feedback—where I can build cloud-native APIs, modern React/Next.js experiences, and reliable CI/CD pipelines with measurable impact.

I’m a Senior Full Stack Engineer with 7 years of experience architecting and delivering production-grade web applications, cloud-native APIs, and high-performance frontend platforms. I bring deep expertise in Python ecosystems—FastAPI, Django, Flask—and modern JavaScript/TypeScript stacks including React, Next.js, and Vue, with a consistent focus on measurable performance and delivery velocity.

Across healthcare, finance, and infrastructure, I’ve owned full product cycles from system design and API architecture through containerized cloud deployment and CI/CD automation. I’ve cut API latency by 40%, improved observability and reduced MTTR by 50%, and compressed release cycles from 3 days to under 4 hours—while building real-time experiences with Django Channels/WebSockets and React dashboards that decouple frontend delivery from backend timelines.
