Code is matter — a living specimen, frontend cut №1

PriyanshuChauhan.

Frontend & platform engineer — Coinbase now, Razorpay before. The specimen is spelling my other name, stackless, forty thousand grains of ink at a time. Carve it with your cursor; it heals. Everything below is cast from the same material.

№1AI-native mentorship platform

Mentorflow

Mentorship with the clerical work removed. The machine listens, writes the minutes, tracks the goals, and books the next session.

Session intelligence: a Whisper + Claude pipeline auto-generates summaries, action items and goal updates from call recordings — backed by an eval harness with confidence-based fallbacks.
RAG-powered retrieval: pgvector embedding similarity replaces keyword search for mentor matching; a scoped RAG assistant recalls your own history in natural language.
Agentic platform: Model Context Protocol exposes Calendar and goal-tracking as tools for autonomous scheduling — Server Actions, RSC, React Query, Clerk.

The provenance paragraph. Every typeface has one; so does every engineer.

A frontend engineer is a workshop for pouring intent into interfaces. This one was cast in Lucknow, annealed at SRM in Chennai, then hardened over three and a half years at Razorpay — authentication for a million merchants, a design system that crosses borders, an AI that answers support tickets before humans wake up. Now it is set remote at Coinbase, drawing onboarding flows for eighty countries from a desk in India. Set it large. Give it a hard problem. Let the counters breathe.
