Custom software development

I develop software that adapts to your business, not a rigid product you have to fit your way of working into. From the internal panel that replaces five scattered spreadsheets to a complete SaaS platform with users, subscriptions and billing.

What I can build for you

  • Custom applications and management panels — internal tools that tidy up your real processes: clients, incidents, stock, students, bookings…
  • ERP and business systems — design, evolution and maintenance of ERP systems, with years of experience in the teaching and exam-preparation sector.
  • SaaS platforms — multi-user, roles and permissions, subscriptions, payment gateway and admin panel.
  • APIs and integrations — so your CRM, your ERP, invoicing and external services talk to each other without copying and pasting data.
  • Microservices — independent, scalable pieces for systems that cannot afford downtime.
  • Legacy system modernization — rescue old applications without risking a total rewrite from scratch.

How I work

First I understand the process: who does what, where information gets stuck and what happens when something fails. Then a quick functional prototype to validate the direction, incremental deliveries you can test from day one and documented, maintainable code, designed so the system is still alive in five years and not just until the next invoice.

Usual stack

  • Backend: PHP 8, Node.js, Python
  • Data: MongoDB, MySQL, PostgreSQL, Redis
  • Frontend: Next.js, React, Tailwind CSS
  • Infrastructure: Linux, Docker, deployment and monitoring

AI integrated where it adds real value

Wherever a language model solves a concrete problem —classifying documentation, extracting data from invoices, answering questions about your own procedure manual— I integrate it in your own infrastructure, with your data and without it leaving it. No sending sensitive information to third-party services.

Do you have a process held together with Excel, WhatsApps and copy/paste? Tell me about it and I'll tell you, with no obligation, whether it is worth automating.
