I build and ship full-stack applications that work in production—not just prototypes. My core stack is React, Next.js, Node.js, and PostgreSQL. I develop complete systems including backend APIs, frontend interfaces, mobile apps (React Native), and deployment pipelines using Docker and Amazon Web Services. I’ve worked on SaaS products, dashboards, and eCommerce platforms with real users, integrating payments (Stripe), authentication, and third-party APIs. I focus on performance, scalability, and clean code so your product doesn’t break as it grows. No hand-holding needed - I can take your idea from concept to deployed product.

For The Real View, I developed a platform that uses AI to analyze strata and condo documents, giving real estate professionals fast insights. The backend runs on Laravel with PostgreSQL for reliable data handling, and the frontend was built in Nuxt for a fast, SEO-friendly interface. I integrated OpenAI for document summarization, Stripe for payments, and deployed everything on AWS with Cloudflare for speed and security.

Strata Share is a platform that makes managing and sharing condo or HOA documents really simple. You can store all your important files in one secure place, share them easily with clients or residents, and control who can see what. It's perfect for real estate pros, property managers, or strata boards who want everything organized and easy to access. I built StrataShare as a full-stack web app that simplifies how strata documents are stored and shared. Using React, TypeScript, and Tailwind, I created a clean, responsive interface, while Supabase handled authentication and storage. I also integrated Stripe for subscriptions and payments, making it a professional SaaS tool for real estate teams.

Developed an AR portal experience using Google ARCore, allowing users to place a virtual doorway in the real world and step into an immersive 3D environment. The implementation uses device motion tracking and environmental understanding to anchor the portal realistically in physical space. When users approach or walk through the portal, they transition from the real-world view into a fully rendered 3D scene with integrated models, creating a seamless mixed-reality effect.

Legends Podcast automation

Mo has been excellent to work with. He built a full production system for my podcast — episode management, a clean dashboard, Google Drive integration, and custom prompt workflows — and handled every round of changes quickly and without fuss. He's responsive, easy to communicate with, and takes feedback on board to get the details right. He clearly knows his stuff technically. Would happily work with him again and recommend him to others.
