I'm Dhaatrik Chowdhury — just a human from India, building stuffs, and this site is my honest engineering diary. Not a polished portfolio. A log of what I shipped, what broke, and what I wish I'd known sooner. I build from first principles because shortcuts always come back to bite you.
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
Right now, my research time is divided into two distinct paths: 90% is focused on demystifying agricultural science from first principles, and the remaining 10% is split between quantum mechanics, rocket propulsion chemistry, and offline AI-driven medical literature analysis.
I am analyzing existing agricultural solutions to get to the ground truth of soil microbiology, crop physiology, seed biotechnology, and climate interactions. This involves heavy deep-dives into organic chemistry, plant pathology, soil macronutrient cycles, and biotechnology to understand what actually drives crop yield and resilience.
Exploring quantum mechanics fundamentals and rocket science, specifically focusing on the chemistry of liquid propellants, combustion chamber heat transfer, and fuel formulations that govern orbital launch vehicle efficiency.
Running Gemma E4B model locally, when my PC is idle (duh! I sleep too) to parse medical literature on Behçet's Syndrome—a chronic systemic vasculitis characterized by HLA-B*51 genetic susceptibility, MHC-I-opathy, and neutrophilic hyperactivation causing blood vessel inflammation. The goal is to develop an early detection protocol and find a cure.
A free, open-source tutoring tool that runs in the browser, stores everything locally, and doesn't need a server or a subscription.
An open-source browser rocket sim with real RK4 orbital mechanics — Kerbal creativity, engineering-grade math, no proprietary license.
A mobile-first fuel delivery app — order from your phone, track the driver live, skip the station detour.
Multiple Gemini agents debate a problem before you get a final answer — not one model talking to itself in a mirror.
The full workbench — Electron utilities, security sandboxes, dining prototypes, and client-side compilers I've shipped, shelved, or am still patching.
Honest transmissions — fuckups, learnings, and late-night debugging sessions.
An honest engineering transmission on building a browser-based orbital mechanics simulator — Kerbal Space Program motivation, 4th-order Runge-Kutta integration, and why I moved physics off the main thread.
My teaching philosophy in plain language — observation before equations, sibling-centric trust, and why I refuse to let students memorize what they do not understand.
An engineering diary on Vellor v4 Power-Tutor — why I built a free offline tutoring tool, how IndexedDB keeps student data private, and what solopreneur teachers actually need.
