A from-scratch driver stack for the STM32F401RE (Cortex-M4) in C — no HAL, no CubeMX, no vendor libraries. Five milestones from a hand-written C runtime to an I2C driver reading a real BME280 sensor, every peripheral verified against a physical stimulus.

A caching reverse proxy in C on a Raspberry Pi 5, built four ways and benchmarked head-to-head — the study wasn't 'which is fastest,' it was how to measure honestly and how much the answer depends on what you optimize for.

A carbon-footprint tracker that turns everyday choices into CO₂e estimates, so making sustainable decisions doesn't require a research project.

A hackathon build with a team — an AI-assisted day planner that helps people carve focus out of overloaded schedules.

A class-project robot that reads light with photoresistors and steers itself through a guided maze.

An Arduino-driven combat robot built from second-hand parts and woodworking — took 2nd place, and led to me running the robotics club.

A microcontroller-driven LED display I designed in Proteus, built on a PCB, and programmed with an Arduino to run light-show patterns.

Two 555-based circuits I designed and built on breadboard — a blinking LED and a light-reactive screaming siren — documented in a full technical report.
