What I'm looking for

I'm looking for a role that challenges my skills and offers opportunities for growth, collaboration, and innovation.

I'm a seasoned Backend Developer with over 10 years of experience in software development, specializing in Golang, Node.js, and cloud-based architectures. My journey has taken me through various industries, including fintech, gaming, and logistics, where I've honed my skills in designing scalable microservices and high-performance APIs. I thrive on problem-solving and performance optimization, always seeking to enhance system reliability and efficiency.

At Hypersonic Labs, I played a pivotal role in developing backend solutions for a gaming application, ensuring low latency and high availability for users worldwide. My contributions included designing high-performance WebSocket services and implementing monitoring solutions to track application health. Previously, I led a team at Piuma Technologies, delivering innovative solutions for startups and enterprise clients, where I successfully transitioned projects from Node.js to Golang to optimize costs and performance. I am passionate about mentoring junior engineers and translating business needs into technical solutions.
