- femus — hardware for PHP developers. Arduino and Raspberry Pi GPIO, sensors, scales, LCDs, 433 MHz packet radio and GSM, driven from plain PHP: typed device drivers, an event loop, precompiled firmware that flashes with one command, and a
FakeBoardso hardware logic is unit-testable in CI. The flagship demo is an offline messenger — an iPhone in airplane mode talking to a Mac over radio you assemble yourself, with a SwiftUI terminal on the phone side. There is also an MCP server, so Claude Code and friends can scan ports, flash firmware and read pins. - ApplyWave — an AI job-search SaaS I built solo from architecture to paying users: Laravel + React/Inertia, a Python/FastAPI aggregation service, multi-model LLM pipelines (Claude / OpenAI) with schema validation and anti-hallucination checks.
Day job, mostly in private repos.
Payments / fintech. Plaid ACH end to end (bank linking, transfers, idempotent webhooks, duplicate-payment prevention), Stripe billing and subscriptions, an EU-licensed crypto escrow platform (atomic balance operations, fund freezing, disputes), and back-office infrastructure at a forex broker clearing $785B+ a month.
Scale and legacy. A top-10 global traffic platform (100M+ daily visitors) through its monolith-to-microservices split. Canada's largest auto marketplace: PHP 5.5 to 8.2, ~3,000 dealer feeds a day, Redis queues, Docker.
Other open source. php-wifi (Wi-Fi scan, join and hotspot from PHP, verified on real hardware) · laravel-rest (Eloquent-like models over REST APIs, adopted across teams at Exness) · laravel-cache-memory (shmop cache driver shared by PHP-FPM and queue workers) · php-serial (serial I/O for PHP 8.2+, extracted from femus).
