// PROJECTS · 15 SHIPPED
Most of these started as "let me write this from scratch to understand it". Pick a layer — every one of them is open source.
// HIGHLIGHTS
A software TCP/IP stack built entirely in C — Ethernet framing, ARP resolution, IP routing, and TCP state machine via Linux TAP devices. Validates by fetching real HTTP content over the custom stack.
Self-hosted SSH key manager for Proxmox — distributes public keys to LXC containers and QEMU VMs via the Proxmox API and pct/qm guest exec, with zero prior SSH access to the guest. Create a container, SSH in immediately.
A free, hands-on course on building AI agents with a fast brain and a slow brain — 12 short notebooks and 13 real use cases that put Jev, a decision model, inside an LLM agent loop. One API key; the whole course runs for under $0.20.
// ♥ BOOT & KERNEL · 02
A minimalistic 16-bit real mode bootloader in x86 Assembly. Demonstrates BIOS interrupt interface, segment:offset addressing, disk sector loading via INT 0x13, and protected mode transition.
An educational multithreaded OS in C demonstrating cooperative and preemptive scheduling, buddy allocator memory management, and message-queue IPC — built to expose the mechanics production kernels abstract away.
// ♥ SYSTEMS & NETWORKING · 05
A high-performance thread-safe logging library for C. Per-thread SPSC ring buffers drained by a background logger thread — zero mutex contention on the write path. 15× throughput improvement over naive mutex approach.
ESP32-based Wake-on-LAN trigger over MQTT. Sits on the LAN, subscribes to MQTT topics, and broadcasts WoL magic packets — built on ESP-IDF with FreeRTOS, lwIP, QoS 1, and hardware watchdog.
A drop-in CLI parser library for C projects. Built-in commands (show, config, debug, clear) plus a registration API for custom commands. Supports tab completion and history via readline integration.
A generic doubly linked list library for C with an integrated "glued type" pattern — one list implementation that any user-defined struct can join without casts or per-type code.
A memory-efficient intrusive doubly linked list library for C. Embedded directly in user-defined data structures — no separate allocation per node, O(1) insert/delete, and type-safe macros.
// DEVELOPER TOOLING · 02
Remote Linux perf profiling with a real-time web UI. Drop a dependency-free agent on any ARM or x86 device, point it at a PID, and watch flame graphs, function tables, and line-level annotated source update live in the browser.
Exact per-call timing for the C/C++ code you choose — and zero cost for the code you don't. One config file picks what gets instrumented at compile time; everything else emits no hook at all. No source changes.
// BACKEND, WEB & INFRA · 01
A unified proxy for OpenAI, Anthropic, Google Gemini, and Perplexity APIs. Single endpoint routes to the correct provider based on model name — swap providers without changing client code.
// AI & AGENTS · 02
Indexed code navigation for AI coding agents — replaces full-tree grep scans with GNU Global (gtags) lookups over the Model Context Protocol. ~100× faster per query on kernel-scale codebases, with radically less context noise.
A twelve-notebook course that builds an AI agent from scratch — a hand-rolled ~35-line agent loop, then RAG, MCP, structured outputs, memory, multi-agent orchestration, and evals layered on top. Works with any OpenAI-compatible provider.
