About

I'm a systems-focused engineer working across embedded firmware, low-level C, and backend infrastructure. I care about code that is correct, efficient, and easy to reason about — whether that's a memory-constrained microcontroller or a server handling real traffic. Based in Ladakh, I work on hardware/software integration projects and contribute to IT systems engineering at Infotech Solutions Ladakh and also founded the company in 2013.

Projects

FIG. 01

Bare-Metal ARM Bootloader Featured

A minimal bootloader written from scratch for ARM Cortex-M targets.

Wrote a minimal bootloader for ARM Cortex-M processors, handling memory initialization, interrupt vector setup, and peripheral configuration without an OS. Used to understand the full boot chain before an RTOS or application code runs.

Network Protocol Analyzer Featured

A C-based tool for inspecting and analyzing network traffic at the packet level.

Built a lightweight protocol analyzer in C for capturing and parsing network packets, useful for debugging custom protocols and understanding traffic patterns in embedded networked devices.

Quantum Gallery Featured

A self-hosted PHP media gallery built for shared hosting constraints.

A PHP-based media gallery application designed to run on shared hosting (DirectAdmin/LiteSpeed), with chunked uploads engineered to work around WAF restrictions on multipart form data, using raw binary POST bodies instead.

PHP SQLite JavaScript

NexusFiles

A single-page PHP file manager with editing and media tools built in.

A full-featured file manager for shared hosting: chunked uploads, image cropping, in-browser code editing, file sharing with expiring links, and EXIF/GPS metadata display — all in a single PHP application.
