CLAUDE SOLUTIONS ARCHITECT · AI PRODUCT ENGINEER

I build with Claude.
Then I ship it.

I'm Prriyankarr "Sunny" Chakraborty. Claude Code is my primary engineering tool: since November 2024 I have built 43 products with it, 23 of them live, from AI-agent oversight and MCP tooling to data platforms. Behind that are 10+ years delivering production systems for clients.

FEATURED WORK

Live products, real data, tested code

Five builds that show the range: AI-agent oversight, agent runtimes, data platforms, SaaS and scientific computing, all built with Claude Code.

01AI oversightLive demo

Tacit

A verified-work layer that grades a company's AI agents against what its people actually do.

Problem. Companies run several AI agents, and none of them can prove its work was right.

Built. Self-hosted, MIT-licensed system that scores every agent against real team behaviour, promotes it through a shadow, propose, then act trust ladder, and keeps a verified-work ledger with EU AI Act Article 12 and 14 evidence.

OMNIRA

An intent-to-outcome runtime that verifies the result actually happened.

Problem. Automation tools run steps, but nothing confirms the outcome you wanted was achieved.

Built. Describe an outcome, get a typed plan, rehearse it, approve it, run it, then verify it. A TypeScript monorepo with a Next.js app, Hono API, Better Auth, a worker and a CLI.

03Data platform · CareersLive

AscentWork

A visa-sponsorship job platform built on government data from seven countries.

Problem. People who need sponsorship can't tell which employers actually sponsor, and job boards rarely say.

Built. Joined sponsor registers from the US (DOL, USCIS), UK, Canada, Ireland, Netherlands, Denmark and Germany to live listings from 675 employer job boards, refreshed hourly, with sponsor grading, in-browser CV matching, AI cover letters and a browser extension.

Crucible

A browser game where every move is a real molecular docking calculation.

Problem. Citizen-science drug discovery games either fake the chemistry or need expensive GPUs.

Built. AutoDock Vina scoring and Monte Carlo pose search in plain JavaScript, four real disease targets, covalent warheads, a guided mode, a shared leaderboard and an AI lab partner served through its own Worker.

OTC Tax Deed Finder

A tax-deed parcel database that surfaces the defects county files hide.

Problem. Over-the-counter tax-deed lists omit problems that make a parcel worthless.

Built. Eight state and federal sources in one subscriber product, with FEMA flood-zone and Census road-access checks, adjoining-parcel groups, an outcome ledger, a deal pipeline and a daily digest. Site and API run on one Cloudflare Worker; CI deploys and asserts the paywall.
