Hello, I'm Prem Kumar

Full-Stack Engineer

Building production web apps end-to-end — backend, frontend, cloud, and CI/CD. 2+ years shipping multi-tenant SaaS.

About Me

Hi, I’m Prem Kumar.

I’m a software engineer at Metapointer Labs with 2+ years of experience owning features end-to-end — Angular frontends, LoopBack 4 / Node.js backends, MongoDB schemas, AWS infrastructure, and CI/CD pipelines on Azure DevOps.

Right now I’m driving the production rollout of an ongoing Node → Go and MongoDB → SQL backend migration — porting APIs and business logic, validating data integrity, and unblocking frontend and mobile teams during cutover. I also handle iOS and Android release cycles (build, debug, ship) and serve as the primary engineering contact for client production issues, including quarterly on-site visits.

I architected a multi-tenant SaaS backend with JWT-based tenant isolation, built notification pipelines across WhatsApp, AWS SES, and Firebase FCM, integrated and self-hosted the open-source Twenty CRM, and led an AWS optimization effort that cut cloud costs 56%.

I lean heavily on AI-assisted development (Claude Code, Copilot) — structured prompting, careful review, and integrating AI-generated code into production-grade architecture. Mentor 3 interns and own backend coding standards for the team.

Originally trained in Chemical Engineering at NIT Warangal — a deliberate switch to software, bringing analytical rigor to every problem I solve.
