Hello, I'mPrem Kumar
Software Engineer
Building production web applications end-to-end from backend APIs and cloud infrastructure to frontend experiences and CI/CD pipelines.
About Me
Hi, I'm Prem Kumar.
I'm a software engineer at Metapointer Labs, where I work across backend systems, frontend applications, cloud infrastructure, and deployments. Most of my day-to-day work involves building APIs, designing multi-tenant systems, integrating third-party services, and keeping production systems running reliably.
Over the last two years I've worked on everything from payment gateways and notification systems to CMS platforms, CRM integrations, CI/CD pipelines, and AWS infrastructure. I enjoy taking ownership of features end-to-end and solving problems that sit between product requirements and technical implementation.
Currently, I'm involved in our migration from Node.js and MongoDB to Go and PostgreSQL, helping port services, validate data integrity, and support frontend and mobile teams through the transition.
I also led an AWS optimization effort that reduced infrastructure costs by 56%, built integrations across WhatsApp, AWS SES, and Firebase FCM, and helped automate customer onboarding through custom CMS and CRM workflows.
