I build systems that have to tell the truth at the edge.
I am Tarun Trilokesh, a solo founder in Bengaluru building JouleBridge: a signed edge runtime for energy sites.
I am not a pure software founder who discovered infrastructure through a cloud dashboard. I came at it from hardware. I started with small robots and UAVs when I was 16, then found my way into nanosatellite electronics, robotics, and industrial controls. The pattern kept repeating: the interesting part of a system is not the UI that reports what happened. It is the device, controller, meter, sensor, gateway, or runtime that decides what can be trusted in the first place.
At TSC Technologies, from 2020 to 2022, I worked on CubeSat electronics in Bengaluru. OBC, EPS, RF, ADCS-support electronics, telemetry, power, board bring-up, EMI and ESD validation, documentation, the unglamorous stack that makes a small satellite more than a neat render. The work covered 0.3U, 1U, and 3U buses. I was 23 when that hardware had to be treated as flight-facing, which is a good age to learn that confidence is cheap and checklists are expensive for a reason.
After that I did my Master of Engineering in Robotics at the University of Maryland, College Park. That period gave me the autonomy side of the stack: visual odometry, path planning, SLAM, perception, tracking, simulation, and the humbling reality that a robot can make a beautiful plan and still lose to lighting, friction, latency, or a sensor mount that moved half a degree. Robotics makes you suspicious of clean diagrams. Good. Clean diagrams hide what the system has not yet been forced to admit.
Wabtec made the lesson heavier. From July 2024 to December 2025, I worked as a controls engineer in Erie, Pennsylvania on off-highway drive and liquid-cooling systems, diagnostics, validation, and high-voltage safety. Heavy industrial systems do not care that a model worked once. They care whether the system behaves under duty cycles, noise, drift, component aging, operator intervention, compliance pressure, and bad days. I left Wabtec on December 26, 2025 and moved back to India because the same edge-truth problem I had seen in satellites, UAVs, and industrial controls was sitting inside the Indian energy transition.
JouleBridge is the company I am building now. It runs at an energy site, beside chargers, meters, batteries, solar inverters, and operator systems. It canonicalizes reads and commands, signs them, applies policy gates, writes a hash-chained ledger, and exports evidence packs that another party can verify without trusting the JouleBridge server. The first wedge is EV depots and energy sites where billing, dispatch, tariffs, and AI-assisted operations create disputes that a normal dashboard cannot settle.
Other engineering work runs at the side. The throughline is the same: trusted edge systems where software touches physical work, records what happened, and survives review after the fact. JouleBridge is the focus.
I am solo by design for this stage. The first hire is a senior protocol or edge engineer after a paid pilot; the second is a utility, AMISP, or EV-depot GTM partner.

Timeline
Electronics and Communication Engineering
New Horizon College of Engineering in Bengaluru. Best Outgoing Student, ECE 2020 batch. This was the period when small robots, quadcopters, CanSats, and bare boards stopped being weekend projects and became the way I learned.
Embedded systems at TSC Technologies
Designed OBC, EPS, RF, and ADCS-support electronics for 0.3U, 1U, and 3U CubeSats. Flight-facing hardware at 23.
Robotics M.Eng at the University of Maryland
Computer vision, SLAM, planning, controls, and simulation. I shipped robotics repos because I learn systems by making them fail in public enough times to respect the parts that look boring.
Controls engineer at Wabtec
Worked on off-highway drive systems, diagnostics, liquid cooling, validation, and high-voltage safety. Heavy industrial systems teach one lesson quickly: the field is the source of truth.
Back to Bengaluru, JouleBridge full-time
I quit Wabtec on December 26, 2025, moved back to India, and started building JouleBridge full-time in January 2026.
The work I want to keep doing is narrow in one sense and large in another. Narrow: build systems where the edge record is trustworthy before anyone optimizes, bills, routes, or reasons on top of it. Large: apply that discipline to energy, autonomy, AI workers, and engineering tools while India is still early enough to build the boring infrastructure correctly.
If you are reading this as an investor, customer, engineer, or future collaborator, the useful question is not whether the site looks busy. It is whether the work shows a person who can ship across the stack when the stack includes metal, protocols, risk, and money. That is the bar I am trying to meet.
