Hi, I'm Costin Moraru, a dedicated Backend Engineer who loves building scalable systems, APIs, and seamless integrations. I’m all about solving problems and I always want to create reliable and efficient backend solutions.

I started my career a long long time ago as a PHP developer, working on everything from web applications to complex business platforms. Over time, I shifted to Go for building high-performance microservices and picked up Rust for handling performance-critical tasks in high-load environments.

Throughout my journey, I’ve worn multiple hats—not just as a developer but also as a team lead and technical manager. This made me understand that good engineering isn’t just about writing code - it’s about collaboration and clear communication.
Whether I’m debugging a tricky issue, optimizing performance, or designing a new system, I aim to build solutions that are clean, maintainable, and built to last.
