PriyanshuChauhan.

Frontend & platform engineer — Coinbase now, Razorpay before. The specimen above is forty thousand particles of ink spelling stackless, the name I ship under. Drag your cursor through it; it heals every time.

№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.

At text size

Every typeface ships with a provenance note. Here's mine.

I grew up in Lucknow and learned to code at SRM in Chennai, where I shipped my first production bug — and my first fix for it. Three and a half years at Razorpay taught me scale: authentication for a million merchants, a design system that crosses borders, an AI assistant answering support tickets before the support team woke up. Now I work remote at Coinbase, building onboarding flows used in eighty-plus countries. Give me a hard problem and room to work; the type sets itself.
