Full-stack systems, CSS 3D research, and production-grade tools. Designed, built, and deployed from concept to live product.
Portfolio
Every project runs on real infrastructure, serves real users, and solves a real problem.
Equestrian stable management covering horse profiles, daily regimes, training journals, health tracking, and expense management. AI-assisted workflows, PDF generation, image processing. Used by real stables daily.
Enterprise fashion platform with AI-powered pattern nesting, voice assistant, real-time WebSockets, Stripe payments, Twilio SMS, OCR, and PDF pipelines. Multi-service Docker deployment with Celery workers and Redis queues.
Business intelligence dashboard that pulls live data from Microsoft Dynamics 365 via Playwright automation. Quarterly KPIs, profitability tracking, and deal pipeline analytics with interactive charts.
3D geometry tool for cuboids, bevels, cylinders, and NURBS surfaces built entirely in CSS transforms. LLM-driven workflow with console commands and live preview.
340+ interactive articles spanning CSS 3D geometry, mathematics, topology, probability, and Apple HIG research. Each post has live demos, copyable code, and LLM-readable breakdowns. Full web-fetch pipeline with Playwright extraction, Cheerio parsing, and PDF processing.
How I work
From architecture to deployment, every layer handled in-house.
Django, Express, PostgreSQL, Redis, Docker, Playwright. Production systems from database to UI, architecture shaped by the problem.
Docker Compose, Cloudflare Tunnels, HAProxy, WireGuard VPN, systemd services. Self-hosted production, real ops, not just dev.
Custom CSS 3D geometry engine for cuboids, bevels, NURBS, and cylinders. All pure CSS transforms with an LLM-driven workflow.
About
I design and build full-stack applications from scratch. Architecture, code, infrastructure, and deployment. Django, Express, PostgreSQL, Redis, Celery, Docker, whatever the problem needs.
AI integrations, browser automation, real-time WebSockets, payment systems, PDF pipelines. I work across the entire stack and ship self-hosted production systems with real users.
