At a glance

What I do, how deep, and what I reach for — before the details.

What I do

Design and build the backend that must not break — money movement, integrations, data at scale. I refactor legacy into something maintainable, then make it fast. Increasingly, I wire AI into the workflow so the whole team ships faster.

// How I think

I connect ideas.

Every place I've worked and the tech I used there, my projects, my craft, and the ideas I can't stop generating — one living graph. Nodes drift in slow orbits; drag to spin it, hover any node.

Things I've built

A live marketplace I own end-to-end, and the platform I lead by day.

A peer-to-peer rental marketplace with Stripe escrow — built solo from schema to production: Laravel API, Filament admin, Next.js web and a mobile app, on a single VM behind Caddy.

Inkomerc — Technical Lead / AI Automation Lead SmartMonitor fleet-monitoring platform — leading the backend in a 12–14-dev team. Refactored the legacy core and introduced a new stack (PHP 8.3→8.4, Laravel 12), scaled the platform horizontally and vertically, and drove speed optimisation across the board. Led the evidence-video (EMS) pipeline, vehicle-camera streaming and CSDD state-registry integration; rolled out Claude Code with ~20 custom skills, adopted team-wide. Built the company code knowledge base — a cross-repo AST code graph linking the Vue frontends to the Laravel API, with on-device vector doc search, served to the team's AI tools over MCP (zero API keys).
