I'm a web developer who writes clean, clear, modular, well-documented code that is easy to test, integrate, and maintain. I've worked with many libraries and frameworks, including Node.js, React, Three.js, Phaser.io, Sass, and have built vanilla JavaScript frameworks from scratch. I also have a little bit of experience in a lot of different programming languages, so I'm comfortable working with whatever tech stack you're using. My favourite jobs involve creating artful user-friendly websites/apps/games that are accessible, and work consistently across devices. To create or modify assets optimized for web, I use Inkscape for SVG, Blender for GLTF/MP3, and Gimp for PNG/JPG. I'm at my best when I'm solving problems and learning new things, and am open to many types of tasks including: - new development - feature addition - 2D/3D asset creation or integration - bug fixes - testing (Windows, MacOS, iOS, Android, Linux) - code reviews - technical documentation

I build AI powered apps that real people actually use. 9M organic views and tens of thousands of App Store installs on products I built and launched myself. Most freelancers can write code. Fewer have shipped their own products, dealt with App Store review, subscription payments, scaling databases, and getting actual users. I've done the full cycle multiple times, so when you hire me you get someone who thinks about your product. What I do best: 🤖 AI App Development 🤖 LLM integrations, multi-agent pipelines (LangChain/LangGraph), AI image and audio generation, chatbots on WhatsApp and the web. I've built everything from an AI supplement scanner with a 250,000+ product database to a WhatsApp bot that composes original songs from a text message. 📱 Mobile Apps (Swift / React Native / Expo) 📱Multiple apps live on the App Store with camera-based AI features, push notifications, Apple sign-in, and subscription monetization. I handle the whole pipeline: build, App Store submission, updates. 🌐 Full-Stack Web (Next.js / TypeScript / Node.js) 🌐 SaaS dashboards, Stripe payments, Postgres/AWS backends, serverless APIs, Shopify apps, and Chrome extensions. 📈 Growth that developers usually can't offer 📈 I grew one of my own apps to 9,000,000 organic TikTok views and 19,000 installs with zero ad spend, backed by an analytics system I built to track every post. If you need someone who understands how apps get users, not just how they get built — that's me. Recent launches: Suppi (AI supplement scanner), OMG AI (photo prank generator), Artificial FM (AI song maker), Slopify (WhatsApp AI music bot), Lobster Sauce (creator research SaaS). I work fast, communicate clearly, and treat every project like it's my own launch. Tell me what you're building and let's get it to the finish line together.
