You've got an idea, or a prototype that works in a demo. The hard part is making it real. Something that holds up when real users and real money show up. And keeps working as you grow.
That's what I do. I take early-stage builds and make them production-grade. Not just features that work today, but a platform that lasts.
𝗪𝗵𝗼 𝗜 𝘄𝗼𝗿𝗸 𝗯𝗲𝘀𝘁 𝘄𝗶𝘁𝗵
You're building your first real platform. You know your business cold, you just need it built like it'll actually run.
Or you've got an AI prototype (Cursor, Lovable, Bolt, ChatGPT) that demos well but isn't ready for real users. You need someone to make it solid.
𝗛𝗼𝘄 𝗜 𝗵𝗲𝗹𝗽
🛠 Plan and build your web or mobile app, from idea to launch.
🔒 Make a prototype production-ready. Security, scale, the parts that break under real load.
⚙️ Harden and upgrade existing systems so they hold up as you grow.
🤖 Add AI and automation where it actually saves time and money.
𝗔𝗯𝗼𝘂𝘁 𝗺𝗲
I've spent 6+ years building software for businesses and founders. I've built for companies like Air Methods and Dropbox, and helped first-time founders in media and healthcare get a real business off the ground.
I care about one thing: software that does its job and keeps doing it. Fast to ship, solid under real use, built to grow with you.
𝗦𝘁𝗮𝗰𝗸
React, React Native, Next.js, Node, TypeScript, AWS, Azure. Project scoping and roadmaps. App support and maintenance.
𝗡𝗲𝘅𝘁 𝘀𝘁𝗲𝗽
Send me a message or invite me to your project. Tell me what you're building. Happy to walk you through how I'd approach it.
