Web systems built
clean, fast & secure.
I design and build websites, web applications and the databases behind them, from first line of code to production deployment.
Services
End-to-end web engineering. I handle every layer, so nothing gets lost in translation between design, code and data.
Web Development
Custom websites and web applications built with modern, maintainable code, responsive by default and fast by design.
Databases
Schema design, optimisation and migrations for SQL Server, MySQL, PostgreSQL and beyond. Data that scales with the product.
Security
Hardened backends, sane authentication and defensive coding practices baked in from the first commit.
UI / UX
Interfaces that feel obvious to use: clean layouts, purposeful motion, zero unnecessary friction.
I'm a developer who cares about the whole stack.
Let me introduce myself: I'm Francisco Javier, and I've always been passionate about computers, retro computing, and classic consoles alike.
I work across web development and database engineering, building products where the frontend, backend and data layer are designed to work together, not bolted on afterwards.
Every project starts with the same question: what's the simplest, most reliable way to build this? That's the BitGecko approach.
If it's repetitive, it shouldn't be manual.
Accounting. Communications. Payroll. HR. The tasks quietly eating your team's week were never meant to be done by hand, they were meant to be automated.
Every repetitive process can be scripted. Every action can be logged. The only thing that should never repeat itself is you, doing the same task for the hundredth time.
$ stop feeding the busywork. build something that runs without you.
Currently building
Not case studies, live systems, in production, doing exactly what the philosophy above preaches.

Local Heritage
Puerto de la Cruz: Un Toque de Color
A historical photo archive of Puerto de la Cruz, researched and hand-colorized frame by frame by Rafael Afonso Carrillo: a proud neighbour of the town, my father, and simply the best one there is. This one isn't just a project, it's a thank you.
