Kavin Jain — Engineer · Udaipur, India
Robotics, embedded systems, and applied ML: from swarm coordination to financial signal processing. The common thread: real-time decision systems with hard constraints, built from the circuit up.
See the workI design and build systems end-to-end: the PCB, the firmware, and the ML that runs on the hardware. Based in Udaipur, India, usually working on problems I couldn’t find an existing answer to.
When I’m not building, I run a daily feeding route for Udaipur’s street animals.
Nowapplying to Japanese universities for robotics & mechatronics · MARK6 paper-trading live on NSE
AlsoHead of Operations across 4 Model UN conferences (delegate awards in 4 committees) · hospitality internship, Justa Hotels

The loop · 01 — perception
Every build starts as a signal read closely: a court that double-books, dogs on a fixed route through the old city, a market that moves before the news lands.
The loop · 02 — planning
Then the model has to close: inverse kinematics for a leg, walk-forward validation for a signal, local rules for a swarm. The math works before the solder melts.
The loop · 03 — actuation
Print it, flash it, deploy it. If it doesn’t run on real hardware in the real world, it doesn’t count. Then the loop starts again.
ESP32 units coordinate over a mesh (no central controller) using local rules for collective exploration, obstacle avoidance, and dynamic task allocation. Hardware designed and soldered by hand.
Five hand-soldered nodes: ~85% arena coverage, zero collisions, <120 ms failover when a node dies.
A 3D-printed quadruped solving inverse kinematics on-board for stable locomotion. Twelve servos and four DC motors on an ESP32 with FABRIK leg-solving: control, firmware, and wiring end to end.
FABRIK at 50 Hz on-board · three gaits auto-selected by IMU · 1.1 kg, 28 h of printing.
A deployed café & court booking platform: real-time availability, a reservation flow, and an admin dashboard for slots, bookings, and customers. Real product work, running in production.
Live at pickora.in for a real venue: conflict-safe bookings across web, admin, and Telegram.
A management system for RYC Model UN: a delegate-registration site paired with an ESP32 + NFC tracker that syncs check-ins to Firebase live and generates attendance logs.
200+ delegates over 3 days; check-in cut from ~8 minutes to ~3 seconds.
monozukuri — the craft of making, taken seriously
No lab nearby. No precedent. Four years of building toward answers that didn’t exist yet.
Fifteen tools · four years · self-taught, from the circuit up.
I read everything that lands here.
