12 projects across full-stack web, SaaS, payments, and AI — built end to end.
A festival-driven 3D greeting card SaaS, built for India's WhatsApp-first audience.
A free 3D animated greeting card maker. Users pick a template, customize text, photos, and music, then share an interactive 3D card via WhatsApp — opened live in the browser with no app install. Includes a Canva-style studio, community feed, premium billing, 16-language support, and an instrumented viral growth loop.
An enterprise AI platform that automates Risk & Control Self-Assessment for banks.
JARVIS RCSA ingests source documents — policies, SOPs, contracts — and uses LLMs to extract process structures, generate visual process maps and Word/PowerPoint SOPs, run verification passes, and produce audit-ready deliverables. Used by risk and compliance teams at financial institutions including Pacific Life. I contributed 528 commits across a multi-tenant codebase of ~179k lines: the Smart Router orchestration system, process-map rendering, reusable Word/PowerPoint/PDF/BPMN export pipelines, and a verification framework that gates AI outputs against regulatory standards (SR 11-7, EU AI Act, DORA, BCBS 239) before export.
