What I'm looking for

I’m looking for a mission-driven team where I can build and scale Python backend services on AWS/GCP, lead migrations, and own reliable async pipelines and high-performance APIs.

I’m a Senior Python Backend Engineer with 5+ years building production systems on AWS and GCP. I focus on shipping reliable APIs, designing scalable data workflows, and improving performance where it directly impacts users and the business.

At Xref, I migrated a 10+ year-old Django monolith to a microservices architecture, splitting 5+ tightly coupled services into independently deployable units and removing cross-team deployment bottlenecks. I also built an AWS Bedrock insights engine on FastAPI, eliminating manual HR analysis and powering async report generation for 10,000+ daily users using SQS and Lambda.

I’ve shipped 15+ REST APIs across Django and FastAPI microservices with token auth, rate limiting, and pagination, with Datadog and CloudWatch monitoring for 10,000+ daily active users. I built async processing pipelines on AWS Lambda, SQS, and Redis to run 20,000+ tasks daily, while optimizing PostgreSQL to cut average response times by 40% and raising test coverage from 75% to 95% to reduce production bugs by 35%.

Previously at Squibler AI, I built backend systems for an AI-powered book writing platform, including document collaboration and permissioned sharing. I delivered features like a version history system using PostgreSQL JSONB diff storage and led a Django upgrade from 2.2 to 3.2, while wiring OpenAI APIs for writing assistance and automated QA test generation that reduced manual QA effort by 30%. My personal projects extend this mindset to AI products and pipelines deployed on GCP Cloud Run.
