What I build for businesses like yours.
AI Chatbots & Assistants
An AI assistant that knows your business inside out — your services, your prices, your hours, your policies — and answers customer questions 24/7. No more missed leads at midnight. Your chatbot learns from YOUR business data, handles inquiries, guides customers toward booking, and sounds like part of your team — not a robot.
Workflow Automation
Those repetitive tasks eating your week? The copy-pasting between apps, the manual follow-ups, the data entry nobody wants to do — I build systems that handle all of that automatically. Connect your tools, automate your processes, and get hours back every week.
Websites & Web Apps
Fast, modern, mobile-ready websites built to convert visitors into customers. Not a template — a custom site designed for YOUR business, with the features you actually need. Everything is built with the same technology used by companies like Netflix and Airbnb.
Power Platform Solutions
Already using Microsoft tools? I build custom apps, automated workflows, and dashboards using Microsoft’s Power Platform — designed to fit into the systems your team already knows. Perfect for businesses that run on Microsoft 365.
From first call to launch — here’s what working with me looks like.
Discovery Call (Free — 30 minutes)
We talk about your business, your challenges, and what you need. No tech jargon, no pressure. I listen, ask questions, and figure out how I can help. If we’re a good fit, I put together a plan.
Custom Proposal (Within 48 hours)
You get a clear proposal with exactly what I’ll build, how long it takes, and what it costs. No surprises, no hidden fees. You’ll know the full scope before you commit.
Build & Collaborate
I build your solution and keep you in the loop with regular updates. You’ll see progress as it happens — not just a final delivery after weeks of silence. Your feedback shapes the final product.
Launch & Support
Your project goes live, and I make sure everything works perfectly. I don’t disappear after launch — I’m here for questions, tweaks, and ongoing support as your business grows.
Real projects. Real businesses. Real results.

I'm Kevin — an AI developer based in Costa Rica.
Before I wrote my first line of code, I was a competitive kickboxer. Muay Thai, kickboxing, BJJ — I spent years training to read opponents, build strategy under pressure, and never quit when things got hard.
That same discipline is what I bring to every project.
For the past 8+ years, I've worked as a Senior Web Developer at a Fortune 500 company, building and maintaining systems used by teams across the Americas. Enterprise-scale problems. Tight deadlines. Zero room for “good enough.”
Now I take that experience and put it to work for small businesses.
I build AI chatbots that answer your customers at 2am. I automate the repetitive tasks that eat your week. I create websites that actually convert visitors into paying customers. And I do it all with the precision of someone who's been solving complex problems for nearly a decade at the enterprise level.
I'm a one-person operation — and that's a feature, not a bug. When you work with me, you get me. Not a junior developer, not an account manager, not a chatbot pretending to be helpful. You get the person who builds your solution, explains it in plain language, and picks up the phone when something needs fixing.
Based in Costa Rica. Working in US timezones. Fluent in English and Spanish. Available evenings and weekends to fit around my full-time role — which means I bring fresh Fortune 500 skills to your project every single day.
“Fortune 500 precision, startup speed.”
Built with precision. Backed by results.
Exceptional work — delivered fast, explained clearly, and it just works.
Kevin built our AI chatbot from scratch and had it live within days. He took the time to understand our business, trained the bot on our actual content, and the results were immediate — customers stopped messaging us asking basic questions because the bot handles it all. Communication was smooth, timelines were respected, and the quality was exactly what we needed. Highly recommend for any business looking to save time and look more professional online.
