Projects
Client work and open-source projects I have built.
💼 Client Work
Built for Michael Distel
FoodRazor
From paper chaos to automated procurement — built the platform that digitizes restaurant invoice processing, automates supplier ordering, and tracks ingredient price fluctuations in real-time. The founder (a serial restaurateur) was drowning in manual paperwork across 5 locations. I architected an Angular + Node.js stack with Firebase real-time sync, OCR-based invoice scanning, and ML-driven price trend predictions. What started as a single-restaurant tool grew into a multi-country operation.

Corecircle
Fitness social network that actually kept people moving — built the backend and ML recommendation engine that matched users with workouts, trainers, and accountability partners. The founder had a vision for AI-driven fitness personalization but the existing codebase was a monolithic Nest.js app that couldn't handle real-time interactions. I introduced Nx monorepo for shared code, Redis pub/sub for live workout sessions, and a collaborative filtering ML pipeline that boosted engagement 3x.
Built for Lila King
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 founder (a former children's TV producer) wanted to combine physical play with digital creativity — I made the tech invisible so kids just have fun.
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 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%.
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 Nastassia Ponomarenko
Connectful
Networking app with Tinder-like UI and Machine Learning algorithm to match like-minded professionals. Built during the pandemic when in-person networking vanished. The founder needed a platform that could replace conference hallway conversations — I built real-time matching with collaborative filtering, virtual event integration, and icebreaker automation that drove 40% weekly active user retention.
Built for Peter Visser
GoPingu
Marketing team management platform with a Trello-like interface and a marketplace of reusable project templates. The founder needed to standardize how 50+ marketing agencies ran their campaigns — I built a drag-and-drop workflow builder, real-time collaboration on task boards, and a template marketplace that reduced campaign setup time from 3 days to 2 hours.
Built for Andy Gough
Microwork
Human-in-the-loop text classification platform — a marketplace connecting businesses needing data labeling with a global workforce. Built the full-stack platform handling user onboarding, task assignment, quality control, and payment processing. The founder needed a reliable way to scale human classification without managing a distributed team manually.
Built for Thomas Wusatiuk
CallTrack
Call center analytics platform — ingests call metadata from Twilio and telephony providers, visualizes agent performance, detects call drop patterns, and automates phone number provisioning based on geographic routing rules. The founder needed visibility into a chaotic multi-provider setup.
Built for Hamish Ogilvy
Sajari
Enterprise dashboard for a search and recommendations engine-as-a-service. Built a single-page application that let customers configure search relevance, monitor query analytics, and A/B test ranking algorithms — without touching code. The founder needed a UI that could surface complex ML model performance to non-technical product managers.
Code Review & Architecture Audit
Deep-dive code review for a Node.js REST API codebase that was falling apart under production load. Documented callback hell, code inconsistency, missing error handling, and security gaps. Delivered a prioritized refactoring roadmap that the team used to cut incident rate by 60% in 3 months.
🔧 Personal Projects
Homelab
