What I'm looking for

I'm looking to build reliable, scalable backend and distributed systems, with opportunities to improve APIs, data workflows, integrations, and engineering practices.

At Commure, I build Python backend services and data-processing pipelines for business-critical systems, including resilient API integrations, web scraping workflows, PostgreSQL loading, and Redis caching.

Previously at Caleta Gaming, I developed backend systems for an international iGaming platform, owned and refactored the Backoffice system, raised automated test coverage from 0% to about 70%, and built reliable financial transaction workflows.

I focus on scalable, maintainable distributed systems using Python, REST APIs, Docker, Kubernetes, AWS, and GCP. I also enjoy improving engineering workflows through RFCs, code reviews, incident postmortems, and mentoring junior developers.
