What I'm looking for

I’m looking for a full-stack role where I can build scalable, production-ready microservices and clean, maintainable systems—collaborating in Agile teams and using AI-assisted development to move faster without sacrificing quality.

I’m a Software Developer with 1 year of professional experience (9 months industry, 3 months internship) and 2 years of freelance experience. I’m versatile across full-stack, backend, frontend, and Android development, and I build with microservices, clean architecture, domain-driven design, and event-driven architecture.

I’ve developed and supported production systems—building microservices for a logistics platform and providing production support for a payment switch system, including real-time transaction monitoring and issue investigations. I also create internal tools like a project tracking system to improve observability and workflow efficiency, and I enjoy shipping practical solutions through REST, SOAP, WebSocket, and GraphQL APIs.
