About
A backend-first engineer who ships full products.
My focus is designing distributed Python systems that solve ambiguous, operational problems at production scale. With a track record of shipping 8 live production applications independently, I handle everything from database schema redesigns and N+1 query elimination to Docker containerization and CI/CD pipelines.
I thrive on products that mix software engineering with real-world complexity: geospatial remote sensing, biometric hardware, real-time telemetry, and high-volume data migrations. I write clean, object-oriented, and testable code to build reliable, customer-obsessed software.
What I uniquely offer
- End-to-end independence
- Database optimizations
- AI & ML productionalization
Core technical stack
- FastAPI, Django, SQLAlchemy
- PyTorch, OpenCV, GDAL
- Docker, K8s, AWS, OCI
Experience
