Figures from real projects. You can open every one in the portfolio section.
I started programming at 15, as a hobby and entirely self-taught: small programs in PHP, jQuery, JavaScript and MySQL, built on documentation, forums and breaking things until they worked. 14 years later I still learn the same way.
Today I build web applications with React and Node.js, Shopify stores and WordPress sites. I also integrate artificial intelligence into real workflows: chatbots with Claude and OpenAI, automation with n8n and custom agents.
Of everything I've done, the work I'm proudest of wasn't for a client. In 2020 I kept the IT infrastructure running for the United Nations peacekeeping mission in the Democratic Republic of the Congo, with the Guatemalan Army special forces contingent: 150 people connected, where going down wasn't an option. Watch the video.
I brought back an idea I apply to everything I build: infrastructure only gets noticed when it fails. The same goes for a store, a website or an AI agent.
I work with companies and founders across Guatemala, Mexico and Central America.
Let's talkShopify stores, WordPress sites and real estate platforms for companies in Guatemala. Every project links to the live site: you can open them and check for yourself.
Most projects that reach me don't need to start over: they need someone to work out why they aren't working. When something has to be built, I build it. When it doesn't, I save you the budget.
How I workFrom online stores and web applications to artificial intelligence integrations. Complete solutions to take your business to the next level.

I build online stores optimized to sell. Complete setup, payment gateways, inventory and custom design that converts visitors into customers.

Corporate websites, blogs and landing pages with WordPress. Custom themes, personalized plugins and speed optimization so your site loads fast.

Custom web application development with React, Next.js and Node.js. Dashboards, SaaS platforms and internal systems tailored to your business needs.

Cloud deployment and management with Google Cloud, Cloudflare and Firebase. Optimized servers, SSL, CDN and monitoring for maximum availability.

Technical optimization so Google finds you. Page speed, Core Web Vitals, meta tags, schema markup and organic positioning strategy.

I integrate artificial intelligence into your business: chatbots with Claude and OpenAI, process automation with n8n, custom AI agents and MCP connections so your team works faster.
What you see here is what I do myself. At Luic I work with a team and we cover larger projects, ongoing maintenance and services that do not fit in a personal portfolio.
I master the most in-demand tools on the market: from frontend frameworks like React and Next.js, to backend with Node.js, PHP and SQL and NoSQL databases.
