About this gig

I build custom fullstack websites and web applications using React, Next.js, PHP and modern databases. Whether you need a simple landing page, a multi-page business website with a contact form, or a full web app with a real database and e-commerce functionality, I can deliver a clean, responsive, production-ready product.


My background is over 10 years of experience solving real technical problems, with the last few years focused on modern JavaScript/TypeScript frameworks, PHP backends and database design (MySQL, PostgreSQL). I run GTresIA, an agency where I also build automations and AI integrations, so I know how to connect your website to forms, APIs, chatbots or payment gateways when needed.


Each project includes clean code, mobile-first responsive design and fast load times. Let's talk about what you need and I will recommend the right package for it.

I'm a full-stack developer, but before writing code I spent 10+ years solving real operational problems in logistics - managing shipments and customer issues under pressure. That shapes how I build: solutions that have to work in the real world, not just demos. Today I focus on n8n automation, AI agents (Claude, GPT, Gemini), and full-stack development (React, Next.js, PHP). I run my own automation agency and e-commerce business, so everything I offer is tested on my own production systems first. Based in Buenos Aires, Argentina. Available worldwide, remote.
