Building reliable software
for real institutions
I work at Topscore Solutions in Ernakulam, where I've designed and shipped two full-stack systems from scratch — a payroll engine and an HR portal — both actively used across multiple institutions.
Beyond my day job, I build SaaS products on my own time: a multi-tenant payroll starter kit with WebAuthn and statutory tax adapters for three countries, a self-hosted career platform with a browser extension and Android companion, and an AI-powered jewellery e-commerce store.
I care about correctness and reliability over novelty. The domains I work in — payroll, HR, admissions — don't forgive bugs.
