VerifiedAbout
Backend and automation engineer with 11 years across enterprise delivery, product teams and independent consulting, including a previous tenure at UST Trivandrum as Lead Developer. I build production services in TypeScript and Node.js and connect systems that don't talk to each other — CRMs, messaging platforms, third-party APIs, internal tools — so data moves without anyone copying it by hand. Currently building multi-tenant SaaS products: a WhatsApp-based lead intake tool for clinics, a B2B outreach CRM, and a bilingual sales platform for vehicle dealers. I've led small engineering teams end to end, covering architecture, code review, CI/CD and delivery. MSc in Information Technology (UK). Currently taking on new work.
