What I'm looking for

I'm seeking a 100% remote software engineering role with strong overlap with U.S. teams, where I can build production web applications, backend services, REST APIs, and product architecture.

I've built and deployed production web products for PlayZone VIP and CourtRank, working across frontend delivery, backend services, databases, and release workflows.

For PlayZone VIP, I developed the official Next.js website, improving performance, SEO, responsiveness, and production readiness while delivering business features from requirements through deployment.

With CourtRank, I've designed a web and mobile platform for real users, building REST APIs, database models, frontend and mobile integrations, and deployment workflows using Node.js, TypeScript, PostgreSQL, and Prisma.

I'm also exploring Java 17, Spring Boot, microservices, and Apache Kafka, applying SOLID principles, design patterns, Docker, GitHub Actions, CI/CD, and Git to create maintainable products for remote teams.
