Roley — Make a Movie!
A web app that turns kids into movie directors. Physical craft boxes with scripts and props pair with a SvelteKit app that records, edits, and merges videos with 50+ transitions using ffmpeg.wasm. Features multi-camera recording, real-time processing, and AWS-backed media storage. The client chose to gate the full app behind a landing page — visitors see the marketing site by default, app is unlocked via `?is-temp-landing=false` URL param.
Built for PayBridge
PayBridge
B2B payment reconciliation SaaS built from scratch. Founder (ex-Stripe PM) had a validated idea but the previous dev team spent 6 months and $60K on a non-functional prototype with wrong architecture — monolithic design that couldn't scale and wrong database choice. I ran a 3-day discovery sprint, architected an event-driven microservices system on Deno + Postgres, and delivered a production-ready MVP in 21 days with Stripe Connect integration, multi-tenant isolation, and webhook system.
Built for MediFlow
MediFlow
Healthcare platform rescue mission. Founder (former nurse) had a working prototype built by an offshore team that was a tech debt nightmare — $8K/month AWS bill, 12-second page loads, no backups, database corruption every 2 weeks. I performed a full infrastructure audit, migrated to Hetzner ($180/mo), rewrote critical query paths, implemented proper backup strategy, monitoring, and zero-downtime deployment pipeline.
Built for WordWeaver
WordWeaver
AI-powered long-form content platform for enterprises. Founder (ex-journalist) had a prototype from AI researchers that was unusable — 40% hallucination rate, no citations, couldn't handle branded content guidelines. I designed a RAG pipeline with citation verification, built a custom MCP server for brand guidelines, implemented human-in-the-loop review workflow, and deployed on self-hosted infrastructure with GPU acceleration.
Built for PropView
PropView
Real estate virtual property tour platform infrastructure overhaul. Founder had a WordPress-based platform that was crashing under load (1.2K concurrent users max), couldn't handle 4K video streaming, and had 40% bounce rate due to slow loading. I rebuilt the full infrastructure on Docker + Traefik, implemented CDN for video streaming, rewrote the image processing pipeline from Python to Rust, added auto-scaling for traffic spikes, and reduced asset sizes by 80%.
🔧 Personal Projects

TodoApp — CalDAV Task Manager (PWA)
