Shivakumar Kokkula

I’m a software engineer with 4+ years of experience building scalable backend systems and production-grade SaaS applications. I specialize in Node.js, microservices, and cloud-native architectures on AWS, with a strong focus on reliability, security, and measurable performance gains.

At Institutional Shareholder Services (ISS), I designed and scaled backend systems powering 5+ enterprise applications used by global teams. I built a domain security scoring engine improving vulnerability prioritization accuracy to 99.9%, and improved API performance by 20% through query optimization, indexing, and caching.

I consistently reduce risk in production by enforcing coding standards and structured reviews—reducing production defects by 15%. I’ve also independently built and shipped AI-driven products, including AI-powered document processing, and collaborated cross-functionally to design scalable, secure backend architectures.

Earlier at Tata Consultancy Services (TCS), I developed secure REST APIs across 4 enterprise-grade applications, implemented JWT authentication, and debugged workflows to reduce deployment errors by 10%. I’ve led a 3-member team, delivered 10+ features across US/EU projects, and earned the Contextual Master Award for technical excellence.
