Summary

I design and build calm software for complicated problems.

A software engineer from Braj, India. Products, AI agents and developer tools — built precisely, documented clearly, and handed over clean.

Selected work

1. devDocs

   2025 – now

   Developer tooling · Design, build and release · v4 in progress

   A CLI that documents a whole codebase — now being rebuilt to spend tokens only where they buy understanding.

   6.1k downloads on PyPI, all versions — All-time total from pepy.tech, which also counts mirrors and CI installs. Six releases since July 2025.

2. Mero Braj

   2024 – 25

   Product · Proposal, grant and technical lead

   A virtual museum for 100+ heritage sites of the Braj region — grant-funded and shipped.

   100+ heritage sites mapped

3. Stuti

   2026

   AI & agents · Design and build · in progress

   A desktop assistant with memory and web search — on its way to an agent that can talk, and act with your permission.

   20 past messages reloaded when it starts — load_history(limit=20) in memoryDB.py, passed to the chat session as history.

4. Trade It Up

   2025

   Quantitative · Research and build · in progress

   A rules-first momentum allocation engine across equity, gold and cash.

   ~10× over 20 years, in backtest — Read off the author’s own backtest chart (the cover), posted in August 2025; Nifty 50 ended near 12× and gold near 8× over the same years. Not a forecast.

   Python · NSE ETF data · Backtesting · Risk rules

5. dts-tracer

   2026

   Developer tooling · Design, build and publish

   Policy-based request tracing for Express, in one line of middleware.

   1 line to adopt — app.use(createTraceRequest())

   TypeScript · Node.js · Express · npm

Teams & engagements

1. Devslane

   2025 – now

   Client products across web, mobile and AI

   • Client-billable projects, wearing whichever hat the work needs: full-stack web, one Flutter codebase for iOS and Android apps, AdonisJS back ends on PostgreSQL and Socket.io, RAG and AI features — and the system designs behind them.
   • CRM and ERP products, owning the client-onboarding module of a live ERP from API design through UI and release.
   • A payment-gateway proof of concept whose approach was approved for production rollout, and a Storybook component library now used across teams.

   TypeScript · React · Flutter · Node.js · AdonisJS · PostgreSQL · Socket.io · Redis · Storybook

2. Legal-tech client

   2025

   A legal-AI platform: retrieval, architecture and sign-in · The client isn’t named here.

   • Cut information-retrieval latency by 40% with targeted query and architecture changes.
   • Refactored core Next.js and NestJS modules to simplify data flow and reduce coupling.
   • Rebuilt authentication end to end on Clerk — 50% fewer login failures and faster onboarding.

   40% faster retrieval · 50% fewer login failures

   Next.js · NestJS · TypeScript · Clerk

3. Mero Braj

   2024 – 25

   Grant-funded heritage platform

   • Wrote the proposal and secured grant funding.
   • Led a team of four to build its first version: a 3D map and 360° tours for 100+ heritage sites.
   • Built for low-end phones: lazy-loaded media and a modular architecture.

   Three.js · Next.js · GraphQL · MongoDB

4. Let’s Unbound

   2024 – 26

   Teaching computer science

   • Delivered 500+ hours of live Python and Java instruction to US AP Computer Science students.
   • Designed project-based curricula, so students shipped working software rather than only passing exams.
