Kalpesh Prajapati — Senior Software Engineer

I'm an experienced and results-oriented Senior Software Development Engineer with a proven track record in building and scaling distributed, event-driven backend systems across domains like fintech and healthtech. With hands-on expertise in C++, Golang, Java, and designing microservices architectures, I specialize in developing secure, high-performance systems that are built to scale. At Skyflow, I’ve led core modules like the Policy Engine and Governance Metadata Services, driving authentication (JWT, API keys, Okta), authorization (RBAC, PBAC), and real-time updates using Kafka and Redis. My work includes deep integration of OpenTelemetry, custom observability frameworks, CI/CD pipelines, and advanced caching strategies for low-latency systems. Previously at Flipkart, I architected and maintained the Gift Card System, delivering high availability and reliability with technologies like Spring Boot, HBase, and Netflix OSS components (Hystrix). My early experience at KiviHealth involved full-stack contributions, helping digitize clinic workflows and scale operations. Backed by a Bachelor's in Information and Communication Technology from DAIICT, I bring strong system design principles, a passion for performance optimization, and a mindset for engineering excellence in every project I undertake.

Rural Internship

Dec 2015 – Dec 2015 · 0 mo · Himachal Pradesh, India · On-site

I worked at SUTRA in December 2015 as part of my rural internship. It is located in Himachal Pradesh. During my time at SUTRA, village elections were taking place, so I worked as a surveyor. My role was to talk with people, understand the problems they were facing under the current gram panchayat, and discuss the issues that should be addressed in the future.
It was an amazing experience—I got to learn new things and also understand the culture of the villages around SUTRA in Himachal Pradesh.
