Firmware Development · BMC · Server Motherboard Technologies

Working on firmware development for server platforms, spanning low-level bring-up, board-level validation, and hardware-software integration.
Developing and debugging BMC (Baseboard Management Controller) firmware for remote monitoring, management, and control of server hardware.
Working with server motherboard technologies — schematics, interfaces, and platform-level subsystems across the system stack.

Firmware BMC / OpenBMC C C++ Embedded Linux

C++ · Bytecode VM · Language Design

Statically-typed scripting language compiled to custom bytecode and run on a register-based VM with mark-sweep GC, closures, and green threads.
Hand-written frontend: lexer, recursive-descent parser, resolver and semantic type-checker covering models, optionals, unions/enums, and match expressions.
Arena-allocated compiler memory, interned strings, bytecode assembler, module system with FFI, and a REPL — no LLVM.

C++23 · Modules · liburing

Single-threaded async runtime on Linux liburing, shipped as C++23 named modules (import rio) — Futures, Tasks, and Promises included.
Sync and async TCP/UDP/file I/O plus a buffered reader, minimal HTTP router/parser, and JSON utilities, with 17 example servers to steal from.
Benches 144k round-trips/s at ~199µs avg RTT over 64k round-trips on 32 clients.

Go · gRPC · DAG Engine

Distributed Map-Reduce / DAG engine: Go coordinator, workers, and a standalone HTTP datastore, wired together over gRPC bidirectional streams.
Affinity-aware scheduling for data locality, WAL-backed recovery, Prometheus-style metrics, and a live web dashboard with TLS/auth support.
Did 10,000×10,000 matmul in ~39s wall-clock (≈17× speedup); ships wordcount, matmul, hashcrack, and primes examples.

C++23 · Build Systems · Single Header

Single-header C++23 build system in one file — your build script is just C++, no new language, no dependencies; already powers the Phos and rio builds.
Sync/async process spawning with file, pipe, and string redirection, leveled colored logging, and a self-recompiling script helper.
Parallel task batches, incremental dependency plans, and compile_commands.json import/export, plus fs, string, time, and diff-test utilities — cross-platform Linux/macOS/Windows.

Computer Vision · Edge Inference

Built an autonomous UAV system to detect and geographically map floating lake trash using a custom semantic segmentation model.
Integrated a real-time aerial image capture and inference pipeline on edge hardware to generate dynamic pollution heatmaps.

Express · Socket.IO · React

Real-time 1:1 chat: Socket.IO presence tracking with per-user socket map, MongoDB persistence, and JWT-cookie auth with bcrypt hashing.
Image messages via Cloudinary, Zustand stores, and a Tailwind UI with sidebar, chat, profile, and settings pages.
