What I'm looking for

I seek senior backend roles focused on scalable, cloud-native systems where I can design reliable APIs, mentor teams, and integrate ML capabilities in secure, production environments.

I am a Senior Python Engineer with 10+ years building scalable backend systems, cloud-native applications, and production-grade platforms for enterprise environments.

My work focuses on high-performance APIs, data-intensive services, and distributed systems using Python, Django, FastAPI, and SQLAlchemy, combined with strong database design and query performance tuning.

I have delivered reliable, secure production systems at AWS, SAP, HCA Healthcare and other organizations, implementing microservices, asynchronous processing, CI/CD pipelines, and monitoring frameworks to improve latency and throughput.

I collaborate effectively with remote, cross-functional teams, mentor engineers, and design maintainable architectures that balance performance, reliability, and data protection while integrating ML capabilities into backend platforms.
