JUL–AUG 2026 · PERSONAL

LoRa garage controller

I designed two ESP32 nodes and custom KiCad PCBs. The radio link uses AES-CTR, the home node communicates with Home Assistant over MQTT, and a distance sensor reports garage-door closure. I developed the ESP-IDF / FreeRTOS firmware and integrated button-terminal control.

Robotics lab NFC access

I replaced hard-coded OrcaSlicer verification checks with backend-managed print permissions. I designed and tested custom NFC-reader PCBs, developed C++ / FreeRTOS firmware and addressed router reliability using OpenWrt on Proxmox.

TensorHost infrastructure

I built RKE2 infrastructure, SSO, access controls, monitoring, telemetry, documentation, wiki, storage and document sharing. I configured versioned container publishing, deployment-manifest updates and pull-request checks, and built a dynamic Vast.ai GPU-pricing engine.

FEB–MAR 2026 · PAIR COURSEWORK

C to RISC-V compiler

I co-developed a compiler from C to RISC-V in C++ with a teammate. It passed 93% of unseen ANSI C tests. My work included nested structures and multidimensional arrays.

MAY–JUN 2026 · TEAM PROJECT

Self balancing waiter robot

I integrated Raspberry Pi 3B, ESP32 and LDROBOT LiDAR components. I contributed to PID control, LiDAR sensing and ZeroMQ communication. The wider team also used A* pathfinding.

JUL–AUG 2026 · PERSONAL

Ender 3 V2 PCB mill

I converted an Ender 3 V2 into a PCB mill using a mount for a Dremel flex shaft, reusing its motion system and sending G-code over UART.

FEB 2025 · IC HACK · TEAM

Wearable braille reader

Our team was runner-up for the Anthropic prize. I built the Raspberry Pi camera subsystem, camera logic and 3D-printed wearable hardware.

SOFTWARE SYSTEMS · COURSEWORK

C shell and concurrent chat

I built a shell and socket-based concurrent chat application in C, including groups. I received 80% for the coursework.

MAY–JUN 2025 · FIRST YEAR

AM-to-UART debugging

I debugged false-positive and false-negative detections using an oscilloscope, adjusting the comparator threshold and envelope detection.

2026 · IC HACK

Engraved coin awards

I designed and fabricated 700 engraved coin awards with clear cases.

IN DEVELOPMENT · SYSTEMS

RV64 operating system

I'm developing a RISC-V operating system targeting RV64 using QEMU and OpenSBI.

IN DEVELOPMENT · HARDWARE

Custom server KVM

I'm developing a custom server KVM using PiKVM and RP2040, combining hardware control with remote access.
