I have worked on computational neuroscience GPU-accelerated clustering pipelines, M&A software, market-data infrastructure, machine-learning tooling, and more. I fancy learning low-level development and building foundational architectures I understand inside and out.

Featured work

Mega Feed Handler preview

Mega Feed Handler

C++ market-data system that replays IEX DEEP+ traffic over UDP multicast, maintains ordered streams, and recovers packet gaps over TCP. Built around a custom MoldUDP64-style transport with retransmission and recovery.

 RiverML preview

RiverML

A from-scratch C++/TypeScript ML pipeline with neural networks, genetic training, backpropagation, and an implementation of gradient-boosted decision trees. Models can be trained, saved, and used in real applications in either language.

TabDock preview

TabDock

A PyQt6 dockable UI framework inspired by IDEs, game engines, and creative tools. It supports resizable docks, draggable panels, floating windows, reusable layouts, theming, and shared state across panels.

 Livestream Particle Life demo

Livestream Particle Life

A particle-life simulation focused on emergent behavior, visual interaction, and live motion. The system shows simple local rules turning into complex large-scale structures. Built during a livestream.
