Senior Frontend Engineer building production React/TypeScript systems by day, and four independent live products by night.
4 years shipping enterprise-scale frontend — 200+ components across 10,000+ pages, and a 24/7 AI-avatar system live in two airports. Outside client work, I design, build, and operate my own products end to end under YK Builds.
ContextForge — Open-source AI-agent CLI & registry
One command makes any repo AI-agent ready for Codex, Claude Code, Cursor, and GitHub Copilot.
- Registry-powered CLI (
npx @contextforge/cli init) — 1,000+ npm downloads within 15 hours of launch - Public, statically served registry fully decoupled from the CLI release cycle
- 20+ MIT-licensed instruction packs, stack-aware auto-detection
- 📦 npm · 📖 docs · source
QwikPass — Multi-tenant restaurant operations SaaS
Digital queue, counter billing, invoicing, and kitchen state in one workspace.
- Organisation → outlet → role RBAC with backend-enforced permissions
- Razorpay Connect integration so merchant funds settle directly to the restaurant
- Metered subscription engine across four plan tiers with per-outlet usage counters
- (private repo — live product, ask me for a walkthrough)
Decisra — Real-time audio decision platform
Audio-only, ephemeral decision space with scoped AI assistance.
- Hybrid WebSocket + SSE pipeline for zero-loss UI state sync across concurrent users
- LLM assistant bound strictly to a single declared decision scope — no context leakage
- Fully ephemeral architecture — zero persistent storage, JWT-based session access
HealthLens — AI medical report companion
Reads lab reports, explains every marker in plain language, and flags concerns — without diagnosing.
- OCR + rule-based marker extraction, configurable reference-range engine
- Controlled LLM workflows validated to withhold diagnostic output
- On-device storage — medical data never touches a server
