Build the web app your business actually needs

Not a brochure. Not a template. I turn your idea into a real system — CRMs, AI-powered workflows and SaaS products that earn while you sleep.

How I take you from idea
to a system that works

Six steps. No mystery. We don't start with pages — we start with your business, then build the software around it. Scroll to walk the whole journey.

01
Discovery

I learn your business inside-out

We map out your current bottlenecks, manual busywork, and lost revenue. Before designing a single screen, we outline exactly where software can save you hours. You get a prioritized workflow roadmap.

Blueprint

We map the system, not the pages

We plan the architecture, data schemas, integrations, and automation triggers. You receive a complete blueprint showing what connects to what, what runs on autopilot, and how it scales.

What I build

Choose the system you need

From a lead-generating site to a full SaaS product — one builder, the whole stack.

Engineered for AI

AI-powered apps

Chatbots that actually know your business, copilots for your team, smart automations and search over your own docs. The stuff that makes people say “wait, your website can do that?”

Best for: Teams wanting to automate 90% of manual email and database workflows.

ChatbotsCopilotsRAG searchAuto workflows
02

Lead-gen websites

Fast, sharp sites engineered to capture and qualify leads on autopilot — not just look pretty.

Best for: Service businesses losing qualified leads to slow, generic landing pages.

03

CRM systems

Know every customer, every deal, every follow-up — in one place built around how you work.

Best for: Teams drowning in disorganized spreadsheets.

04

Booking & scheduling

Let clients book, pay and reschedule themselves while you get your calendar back.

Best for: Appointment businesses with too much admin overhead.

05

ERP & internal tools

Inventory, ops, finance, HR — the unglamorous software that quietly runs the business.

Best for: Companies scaling past manual internal operations.

06

Client portals

A branded, secure space where customers log in, self-serve and stay loyal.

Best for: Client-facing service firms wanting to look premium.

07

SaaS products

Your idea, packaged with billing and accounts — a product that earns while you sleep.

Best for: Turning a repeated internal workflow into a commercial software asset.

Why work with me

Your site should pull its weight

Most sites are expensive brochures. Mine earn their keep four ways over — follow the trail down ↓

Lead generator

Built to attract, capture and qualify the right people — so your pipeline fills itself instead of going quiet.

Meet the builder

Reyes Prince

I don’t just build websites. I engineer systems that run your business on autopilot.

After years of watching companies pay thousands for pretty templates that did nothing for their bottom line, I decided to do things differently. I build custom, production-grade tools tailored exactly to how you work.

The philosophy

No templates. No compromises.

If your business is unique, your software should be too.

Most agencies reuse the same Webflow or WordPress templates, leaving you with heavy, slow, rigid sites. I write clean React and Next.js code from scratch. That means your app loads instantly, handles complex data, and integrates with anything.

The stack

Modern tech, built to scale.

We build it once, build it right, and package it to last.

From custom booking portals to AI-driven customer workflows, I use modern developer-first tools. My go-to backend database is Convex, enabling me to build real-time reactive features in days rather than weeks. If we build something game-changing, we can package it with Stripe Billing so you can sell it as a SaaS.

The promise

Your tech partner, on retainer.

You focus on the business. I handle all of the code.

I don’t just hand over code and vanish. We can work together long-term. As your engineering partner, I take care of hosting, scaling, API updates, and new features so you can focus entirely on growth, operations, and sales.

Word on the street

Proven results, no fluff

Don’t just take my word for it. Here is how custom systems transformed these businesses.

Reyes built our booking portal from scratch in 4 weeks. It handled $12k in transactions in the first weekend alone with zero issues. Unbelievable engineer.

Sarah Jenkins, CEO, Coastline Clinic

We replaced three separate SaaS subscriptions with a single custom dashboard Reyes designed. It’s faster, we own the data, and it saved us $900/month.

Marc L., Founder, Lumen CRM

The AI agent Reyes built answers 90% of our support emails instantly. Our clients get answers immediately, and our team actually gets to sleep at night.

Devon Croft, Head of Support, Halo Support

His custom billing flows and clean UX let us package our internal tools into a commercial SaaS. Reyes doesn’t just code — he understands business model design.
