Hi, I'm VisheshI build the firmware that runs the things you don't think about.

I work close to the silicon — Linux on iMX6ULL, ESP32, STM32 L-series — shipping OTA, drivers and Qt apps that have to keep working in the field.

I'm a firmware engineer with four years of shipping embedded products — from eBike controllers to industrial Linux devices.

I like the layer where physics meets software: writing non-blocking drivers, tuning RTOS schedulers, fighting bandwidth limits to ship an OTA update, tracing weird behaviour with a logic analyzer at 2am.

Right now I'm at Halma India building a Qt/C++ Linux application on NXP iMX6ULL — customising device trees, cutting build times 4× with cross-compilation, and designing OTA mechanisms that work on storage-constrained hardware without A/B partitioning.

Off the clock: smart-home tinkering, finance reading, a long-running D&D campaign, and currently rebuilding a Raspberry Pi Zero 2W into a self-hosted homelab — which, yes, is what's serving this page.

Things I've built. A few are still humming somewhere.

// 01case study →

OTA without A/B

A staged update mechanism for storage-constrained Linux devices that survives flaky cellular and partial writes — without doubling up on flash.

eBike firmware platform

End-to-end firmware for a connected eBike: BMS control, brushless motor driving, BLE pairing, user profiles, and an OTA path through a phone app.

Qt on iMX6ULL

Custom Yocto image, tuned device tree, and a multi-process Qt/C++ application that cut response time in half on an industrial SBC.

Non-blocking driver kit

Reusable interrupt-driven state machines for concurrent peripheral I/O on bare-metal — read sensors without stalling the main loop.

Static-analysis pipeline

cppcheck + flawfinder + clang-tidy wired into CI for an embedded codebase. Caught 30+ classes of bug before flash and made our review process honest.
