Hi, I'm Stephen. I've spent six years building and shipping consumer apps, AI products, and marketplaces. Started Blupalms at 21, right after I built and sold my first app in college. Since then I've taken products from a blank page to launch for funded founders, and I run my own apps too. One of them, SPF, is past 350,000 downloads. Here's the thing I keep running into lately. People build something fast with AI, get it most of the way there, then it stalls. The last stretch is where apps actually break. The polish, the store approval, the parts that have to hold up once real people are using it. That last 20% is the whole job now, and it's what I'm good at. What that's looked like over six years: 🏆 Apps I've worked on have charted on the App Store, more than once 📲 Over a million downloads across the products I've shipped 🔁 $5M+ in transactions running through marketplaces I built ⭐ 100% Job Success and Top Rated Plus across 95+ projects here When you hire me, you get me. I don't pad scope and I don't hand you off to a junior after the sales call. I cover the full path of getting a product out the door: strategy, design, build direction, launch. I bring senior engineering help when the scope calls for it, but the product thinking stays with me from day one. Most of my work right now is AI. Custom LLM features, chat and agent interfaces, AI-native SaaS, automation. Outside of that I'm strongest on consumer mobile and two-sided marketplaces. How I like to start is a paid app audit. You send me what you've built, in whatever state it's in, and I tell you exactly what's standing between it and a real launch. You walk away with a clear, prioritized plan you can run with, whether or not we keep working together. Most people have me take it the rest of the way from there. That's where it turns into build, ship, and ongoing support if you want it. If you've raised money or you have revenue, and you're building something real in mobile, AI, or marketplaces, send me a message with what you're working on. We'll go from there.
