What I'm looking for

I'm looking to own full-stack features end-to-end, contribute to technical decisions, improve architecture and delivery automation, and build scalable products with measurable business impact.

At Freshcode, I design microservices, improve PostgreSQL performance, automate internal processes, and strengthen CI/CD workflows. I've reduced monthly infrastructure costs by 23%, resolved production issues with long-term fixes, and mentored junior and mid-level developers.

Previously at Voypost, I delivered end-to-end Adyen payment integrations, built reusable design-system components, and raised test coverage above 90%. I also redesigned a multi-step verification flow that reduced abandonment by 27% and migrated a legacy codebase to TypeScript.
