What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and professional growth.

As a Senior Software Engineer, I have a proven track record of developing high-performance microservices and applications that enhance operational efficiency and user satisfaction. At Buyandship Limited, I successfully developed over three production-ready microservices in Golang, which cut operational time by 40% and facilitated the launch of a new platform within just seven months. My collaborative approach with product managers and designers has consistently resulted in timely feature releases, achieving a 95% success rate in sprints.

Previously, at Clover Health, I focused on improving the scalability and performance of healthcare applications while ensuring HIPAA compliance. My efforts led to a 15% increase in user satisfaction and a system uptime of 99.95%. I take pride in my ability to write comprehensive Technical Design Documents that streamline onboarding for new developers and enhance team workflows. My commitment to quality is reflected in achieving 100% unit test coverage on key services, significantly reducing defect tracking time.

In addition to my professional experience, I have developed a cross-platform dating app as a personal project, showcasing my full-stack development skills and modern authentication techniques. I am passionate about leveraging technology to solve complex problems and continuously seek opportunities for growth and innovation in my career.
