I'm Dhaatrik Chowdhury, an engineer from India building practical software from first principles. This site is my honest engineering diary, not a polished portfolio. It is an open log of what I shipped, what broke in production, and the lessons I wish I had learned sooner. I avoid shortcuts because they always come back to charge interest.
Things I'm building, abandoning, or still fixing at 2 AM.
Investigating agricultural systems from first principles—soil chemistry, plant biology, and biotech (90%)—while allocating time to quantum mechanics, rocketry, and Behçet's Syndrome literature.
STATUS: RESEARCH_ACTIVE // CORE: AGRI_BIO_TECH
I am breaking down agricultural workflows to fundamental principles. Most commercial tools optimize for corporate dashboards rather than actual ground truth. I am studying soil microbiology, chemical balance, and local weather patterns to engineer tools that solve real operational friction for farmers.
Investigating crop health telemetry, sensor networks, and offline sync.
DeltaV Lab mathematical modeling, multi-stage trajectories, and Web Workers.
Reviewing open clinical literature and immunology pathways.
Free MIT-licensed tutoring-management PWA — students, lessons, payments, invoices, offline on your device. Not note-taking; not SaaS.
"I misdocumented Vellor as note-taking with IndexedDB on this site — the repo encrypts to localStorage with AES-GCM, and I nearly buried invoicing under RPG-style gamification chrome."
Open-source browser rocket sim — VAB, Mission Control, RK4 physics in a Web Worker. Honest about what it teaches and what it cannot certify.
"I initially passed hundreds of small coordinates to the Web Worker every frame, which clogged the thread and destroyed the physics loop's real-time accuracy."
Frontend-only fuel delivery UX demo v3.0.0 — customer ordering, captain dashboard, Leaflet map UI, PWA. Not WebSocket production logistics.
"I described WebSocket live tracking and server rollbacks on this site — the repo is a frontend-only demo where optimistic UI runs on mock state with no database to fail."
BYOK multi-agent council v4.0.0 — parallel/sequential/round-robin, HITL, branching, PDF export via gemma-4-31b-it. Client-only, no backend.
"I ran an unbounded multi-agent debate test without depth caps and woke up to a rate-limited API key — v4 adds token/cost visibility but you still own the guardrails."
The full engineering workbench — deep-link handoffs, feedback terminals, POS demos, dining prototypes, and client-side compilers I've shipped, shelved, or am still patching.
Honest transmissions — fuckups, learnings, and late-night debugging sessions.
MIT-licensed BYOK multi-agent tool v4.0.0: you supply Gemini API keys, pay per token, and must cap debate depth — honest economics and limits.
Why v4.0.0 uses React 19 + Vite 6 + @google/genai with html2canvas/jsPDF export — no server, BYOK Gemini calls from the browser.
Honest origin story for The Infinite Intelligence v4.0.0: BYOK multi-agent orchestration with HITL, branching, and synthesis — not three generic Gemini roles.
