I build systems that hold. Then I teach them to think.
Founder and engineer in Kolkata. Backend engineering and AI research lead my work: APIs, microservices, AI agents and automations, built to survive production.

I see systems. Not isolated tasks.
I don't get excited by vanity metrics or fancy titles. My first question is always the same: okay, but what's actually happening here? I see systems, not isolated tasks. I see the next ten problems that appear after today's problem is solved. So I build for what works: elegant systems, honest numbers, and execution that compounds.
- 01Architecture firstDecide the shape of the system before anyone writes a line.
- 02Data models secondGet the nouns right and half the bugs never exist.
- 03Contracts thirdAPIs are promises. Write them down before you keep them.
- 04Implementation lastBy now the code is the easy part, so it ships clean.
Open source · Built in public
Tools that ship. Then keep shipping.
Products, developer tools and templates I build in the open. Each one exists because a real workflow was slower than it needed to be.
Everything in the labTypeScript
Conventional Commits CLI
AI-powered commit messages with privacy-first intelligence. Generates commits from staged changes using OpenAI, Anthropic, xAI or Gemini, with built-in secret detection, mandatory review and cross-platform binaries.
Go
thineRC
One-word superpowers for your terminal: free stuck ports, reclaim disk, read memory honestly, and turn aliases into typed recipes, with previews and undo. Go, for Linux and macOS.
TypeScript
React Native App Template
React Native + Expo template for iOS and Android with strict TypeScript, routing, validated APIs, themes, tests and CI, plus Claude Code conventions: scoped rules, skills, review and test agents.
TypeScript
NestJS Microservice Template
Production-minded NestJS + Mongoose starting point for microservices, with a sibling Express template for plain Node.js services.
Installable on skills.sh
Judgment, packaged for agents.
Reusable frameworks I wrote so AI agents prompt clearly, commit cleanly, review like a principal engineer and never lose context between sessions. Read the write-ups →
- 01Prompt design
ART Prompt Framework
Turn rough ideas into precise, effective prompts with ART: Act as, Request, and Terms.
- 02Engineering judgment
Principal Engineer OS
Principal-engineer judgment for architecture, code review, debugging, refactoring, migrations and production readiness.
- 03Developer workflows
Conventional Commits Framework
Complete, atomic, co-authored commits every time, with an offline checker and commitlint config.
- 04Decision support
CoMPaSS Prompt Framework
Analysis-first prompting: understand intention before writing the prompt, then define what done looks like.
- 05Session continuity
Handoff
Save and resume session context so any AI agent continues work from exactly where the last one stopped.
Production first, then companies
Shipped at scale. Then built companies.
Backend engineering at Quizizz and Yellow Class taught me what production really asks for. Everything I build at YourAKShaw, NayaManas and Codeinn starts from those lessons.
