What I'm looking for

I seek backend-focused roles building scalable APIs and microservices in Agile teams, with opportunities to use Java/Spring, CI/CD, Docker/Kubernetes, and grow toward system architecture responsibilities.

I am a backend developer with hands-on experience designing and implementing RESTful APIs and microservices using Java/Spring Boot, PHP/Laravel, and Python/FastAPI. I have delivered full-featured systems such as digital wallets, MVPs in DDD/SOA paradigms, and integrations for KYC and third-party liquidity providers while applying CI/CD, Docker, and Kubernetes practices.

I emphasize clean architecture, testability, and scalable design, drawing on patterns like DDD, TDD, and event-driven systems. I work well in Agile and multicultural teams, contribute across the stack when needed, and continuously expand my skills in frontend development, data analysis, and security-focused practices.
