Why Jonathan
As a former NCAA Track & Field athlete, I know what it takes to train for something bigger than yourself — discipline, repetition, and the drive to execute when it counts. I bring that same mentality to every app I build. I don't just write code. I obsess over bringing your vision to life, the same way I used to obsess over shaving milliseconds off my time.
Athletes don't miss practice. I don't miss deadlines. Every sprint, every milestone, delivered on time with the same discipline that defined my athletic career.
I've built apps from zero — an AI wellness app, a social card game, healthcare platforms. I don't just code what you hand me. I help you think through the details that make the difference.
Six years at Infosys and Bridgeview building production iOS apps for real users. Your app won't be a side project — it'll be built to the standard of a seasoned professional.

Pricing
Fixed-price projects. No surprises, no hourly billing. Every project starts with a free estimate call where I scope exactly what you need.
What to expect
All third-party accounts (Square, etc.) are set up and owned by you.
How it works
We walk through your idea, goals, and requirements. I scope the project accurately and give you a clear number — before any money changes hands.
You receive a detailed proposal with a full feature list, fixed price, and timeline. Once signed, development begins with a deposit.
I build in focused sprints with regular check-ins. You see real progress at each milestone before the next payment is due.
Two dedicated weeks of QA before launch. I handle App Store submission and make sure everything runs smoothly on day one.
First month of support is on me — no charge. Ongoing maintenance available at $1,000/month covering updates, OS compatibility, and API changes.
Tell me about your project. I'll get back to you within 24 hours.
