What I'm looking for

I am looking for a role that challenges me technically and offers opportunities for mentorship and growth.

As a Senior Backend Engineer with 9 years of experience, I have a proven track record of developing scalable, high-performance backend systems. My expertise lies in JavaScript, TypeScript, Python, and Go, with a strong focus on API design and server performance optimization. I thrive in fast-paced environments, where I can leverage my skills in cloud-based microservices architectures and DevOps practices to deliver clean, maintainable code.

At Medely, I developed a healthcare staffing platform that achieved 99.9% uptime and improved response times by 30%. My role involved architecting scalable microservices, implementing real-time communications, and integrating AI-driven algorithms to enhance job matching accuracy. I am passionate about mentoring junior engineers and collaborating with cross-functional teams to drive productivity and innovation.
