Francisco Márquez Arenas

I develop modern web applications and connect them with artificial intelligence so that businesses save time and do not lose customers by not responding promptly.

My differentiator compared to other web development profiles: I don't stop at the web. I integrate AI chatbots that truly respond — not generic bots, but assistants connected to the business's real information, capable of executing actions (checking prices, capturing contacts, managing appointments), not just holding a conversation.

I built Invexia (invexia.app), a platform of financial calculators with an integrated AI assistant that performs real user calculations — not a chatbot that only talks, one that does the work. Full-stack in Next.js, with custom design, SEO, and production deployment.

I work with a closed scope and price from the beginning, with no surprises mid-project, and with regular updates as I develop. If your business needs a website, an assistant to attend to your clients 24/7, or to connect tools that currently work separately, let's talk.
