What I'm looking for

I seek a role leading architecture and engineering teams where I can design scalable systems, improve testing/CI practices, mentor engineers, and deliver reliable, automated solutions.

Senior Software Engineer & Tech Lead with 5+ years architecting full-stack, microservices-based systems. I design backend and frontend architectures using SOLID and Clean Architecture principles to ship maintainable, testable software at scale.

At Etourney, I led both frontend and backend teams as the sole architect, building the entire system in NestJS, designing the databases, and automating integrations with game SDKs to orchestrate live tournaments. I champion CI/CD and containerization to keep releases fast and reliable.

Previously, I introduced end-to-end testing with Cypress and unit/integration testing practices, built core business logic in Spring Boot and Node.js, and shipped reusable React components that improved UX across MySQL- and MongoDB-backed products.

I'm looking for my next role as a Tech Lead or Senior/Staff Engineer where I can own architecture decisions, mentor engineers, and help a team scale — ideally remote-first, full-stack. Open to hearing about new opportunities, feel free to reach out directly.
