What I'm looking for

I seek backend-focused roles where I can build reliable, automated systems, improve performance, and collaborate on clean engineering practices in a growth-oriented team.

I am a results-driven software engineer with strong Python backend experience, proven in production systems that improved performance, reliability, and observability. I migrated databases and optimized queries to cut dashboard load from minutes to seconds, built company-wide Flask tooling with SSO, and automated reporting and CI/CD workflows to eliminate repetitive manual tasks.

I collaborate across teams to translate domain requirements into robust code, delivered migrations with zero data loss, and built serverless policy engines under compliance constraints. I value clean standards and knowledge sharing—authored PR guidelines, standardized dependencies, and taught internal training to engineers.
