What I'm looking for

I'm looking for a role that fosters collaboration, innovation, and growth opportunities.

I'm a Backend Engineer driven by a genuine passion for building scalable, secure, and high-performance systems that help businesses reach their full potential. I have hands-on experience designing and deploying microservices in languages like Golang, PHP, Elixir, and Java, and I enjoy crafting RESTful APIs, refining database schemas, and implementing event-driven patterns using tools like RabbitMQ.

I’m particularly drawn to solving performance and scalability challenges and take pride in thinking critically about system design with a long-term lens. Whether it’s collaborating across teams, mentoring peers, or streamlining build processes, I bring a balanced mix of curiosity, accountability, and clear communication to every stage of the development lifecycle.
