Backend Developer specialized in Golang and Java, with experience also in TypeScript, focused on building scalable APIs, security-aware services, and distributed backend systems. I have developed authentication systems, developer tooling, and infrastructure-level services using Spring Boot, Fiber, Gin, PostgreSQL, and Redis, supported by Docker, CI/CD pipelines, and Linux-based environments. I combine software architecture, automation, and security-oriented design to build reliable and maintainable backend platforms.
