View ProjectsAbout Me

Hi, I'm Hemakumar M, a Backend Developer with 2+ years of experience building scalable Node.js applications. I hold a Bachelor's in Computer Science from Global Institute of Engineering & Technology and specialize in TypeScript, AWS, and microservices architecture.
Currently working at Willeder Inc in Tokyo, I've optimized Node.js APIs reducing latency by 40% for 5,000+ daily users. Previously at Primates Development, I improved server response times by 30% through enhanced database queries and caching mechanisms.
I'm passionate about building high-performance backend systems and have won hackathons including 1st place at Mars Asia Hackathon for Block Space, a decentralized storage dApp using IPFS & Polygon SDK.
I enjoy solving complex technical challenges and am always exploring new technologies to create innovative solutions that drive business growth.
