What I'm looking for

I'm looking to build scalable backend and distributed systems where I can improve reliability, security, and high-volume data processing while mentoring engineers and collaborating across teams.

I've built backend platforms for Alight Worklife, Pharma Datasphere, Finbook, and cybersecurity ticketing systems, delivering secure APIs, MFA workflows, rate limiting, and distributed data processing. My work spans Python services built with FastAPI, Django, and Flask across fintech, enterprise, pharmaceutical, and cybersecurity products.

I've improved high-volume ingestion with asynchronous and Kafka-based processing, built idempotent event workflows, integrated AWS services and LDAP, and optimized search and access control. I also mentor engineers and focus on reliable, maintainable backend systems.
