What I'm looking for

I am looking for a challenging role in a dynamic environment that fosters innovation and offers opportunities for professional growth.

I am a Backend Engineer with over 4 years of experience specializing in GoLang, TypeScript, NodeJS, and AWS. My journey has been marked by a commitment to optimizing system performance and ensuring high availability in fast-paced environments. At Metric Gaming, I led the design and development of Golang code for a high-traffic sports betting platform, enhancing system functionality and introducing new features.

My experience extends to developing RESTful APIs and implementing gRPC services that significantly reduced response times. I have a proven track record of collaborating cross-functionally to resolve system bugs and contribute to incident response efforts, ensuring minimal service interruptions. I am passionate about leveraging my skills in distributed systems and event-driven architectures to drive innovation and efficiency in technology.
