Hi, I’m Jesus.

I think about techso you don’t have to.

You’re a founder.
You have a business to grow.

You know your business. You know the people you want to serve. You have enough to think about without the technical side taking over your day.

You can build with AI yourself. I do, too. The question is what it costs your business when you’re the one doing the building. An outage can take over the morning. A stubborn problem can turn into hours of arguing with AI. Meanwhile, the customer you meant to follow up with is still waiting.

Hiring me is a different choice: you pay me to take on the product work so you can put your attention where you want it.

Maybe that’s selling to one big customer. Maybe it’s growing an audience, meeting partners, or spending more time with the people who already buy from you.

Working together

This is the part I like doing.

I’ve spent more than a decade building products for founders, end users, and Fortune 500 clients. I chose this work because I like figuring out how things should work and then building them. AI lets me do more of it.

My early career in consulting taught me to meet people where they are. You might have an idea, an AI-built prototype, or customers already using your product. We start there. You don’t need to turn what you know into a perfect set of instructions before we can work together.

We talk through what you want people to be able to do. I work out the technical approach, build it, and bring you something you can respond to. When a decision affects the business, we make it together. You shouldn’t have to chase every task or supervise a conversation between me and an AI.

More about my experience

A founder I work with

Momentum Kinetix / Martial World

Martial World’s founder came to me with an idea for connecting martial arts gyms across Chicago and a basic HTML prototype. He knew the market and the community he wanted to serve.

We worked together on the product, strategy, and requirements. I built the marketplace and the system behind it: memberships, billing, check-in, gym management, reporting, referrals, and partner payments. We continue working together as the business grows.

From Martial World’s The Network Report
Issue 02 · November 2026

What’s happening in the business

  • A network of more than 20 Partner gyms

    Boxing, BJJ, Muay Thai, karate, wrestling, and other disciplines on one Network Pass. Independent gyms participating in a shared membership across Chicago.

  • A membership people can buy

    The Explorer Pass offers four visits a month for $49. The founder’s holiday offer adds locked founding pricing, event access, a find-your-fit call, and a gift option. If a member doesn’t find a gym they want to return to within 30 days, their first month is refunded.

  • Partners doing business together

    One Mat brought gym owners, coaches, ambassadors, newcomers, and five local vendors together at Fabrik. Coaches exchanged open-mat schedules. Partner dojos are also planning a joint karate tournament and seminar.

  • A creator program to reach new members

    Chicago creators get a 30-day Adept Pass with six classes. They train at multiple Partner gyms and share three honest videos about the experience, with an additional payment tied to views.

  • A school partnership

    With Teamwork Englewood, Martial World is bringing an eight-week parent self-defense series to Englewood STEM High School.

  • A regular way for people to get started

    Common Ground offers free Sunday training across four Chicago parks. Monthly sessions at Fabrik include beginner-friendly self-defense and movement classes.

I don’t want either of us
babysitting the software.

My ideal engagement leaves you with a product that doesn’t need either of us hovering over it every day. We can spend our time on what you want to do next, rather than keeping the same things running.

That shapes how I build and where I deploy. I like Cloudflare because it makes experimentation affordable and keeps a lot of the infrastructure work out of the way. I care about what the product costs to run and how much attention it needs after launch.

The technical details

Most of my web work uses React, TypeScript, TanStack Start, and Cloudflare Workers, with D1 and R2 for data and file storage.

For accounts and payments, I use Better Auth, Drizzle, Stripe, and Stripe Connect. I handle infrastructure, deployment, and data migrations as part of the product work.

The exact stack depends on the product. I care about what it costs to run, how easy it is to change, and whether it can keep working without either of us hovering over it every day.
