What I'm looking for

I'm looking to build scalable, production-grade cloud systems where I can turn cross-functional requirements into reliable software, improve delivery through automation and observability, and mentor engineers.

At TaskRabbit (IKEA), I architect and deploy AWS infrastructure for real-time marketplace data processing across 50+ metro markets, increasing transaction efficiency by 30%.

I build Python and Flask services for payment processing and scheduling, reducing peak-traffic latency by 25%. I also developed CloudWatch observability that supports 99.9% availability and healthcare compliance.

Previously at Tandem, I helped scale a real-time shift-matching platform from prototype to multi-market operations. My Node.js microservices and GraphQL APIs improved worker-to-shift match rates by 50%, while Docker and Kubernetes reduced deployments from hours to minutes.

At JPMorgan Chase, I worked on secure Java and Spring applications processing billions of dollars in daily transactions. I enjoy translating cross-functional requirements into reliable systems, strengthening CI/CD and testing practices, and mentoring engineers through code review and deployment strategy.
