CUSTOM WEB PROGRAMMING

API Development & Integrations

Make your systems talk to each other and stop manual data entry.

Do you have sales data in one place and invoicing in another? That's a recipe for error. I specialize in building RESTful APIs and connecting third-party services (Stripe, PayPal, CRMs, ERPs, Google Sheets). I build the digital "bridges" needed for information to flow automatically between your platforms, saving you hundreds of hours in manual management and ensuring data integrity.

Automation Scripts (Python)

If it's repetitive, a robot should do it.

Your time is too valuable to spend copying Excel rows or downloading daily reports. I create custom Python scripts to automate tedious tasks: web scraping (data extraction), automatic PDF report generation, bulk email sending, or image processing. Free your human team from mechanical work so they can focus on strategic tasks.

Database Design & Optimization

Solid architecture for when Excel can no longer keep up.

Poor data design can sink your application's performance. I design and optimize relational databases (PostgreSQL, MySQL) built to scale. I ensure your information is structured, secure, and accessible at high speed. If your current system is slow or you have duplicated and messy data, I restructure your architecture to support future growth without bottlenecks.

Refactoring & Legacy Code

Fix and modernize your current software before scrapping it all.

Did you inherit a project with "spaghetti" code or have an old application that is impossible to maintain? Starting from scratch isn't always necessary. I analyze and refactor existing code to improve its readability, security, and performance. I update library versions and clean up technical debt so your software becomes manageable and secure again, extending its lifespan and protecting your previous investment.

VeriFactu & Bilteo Integration

Solution for the new mandatory electronic invoicing (Crea y Crece Law).

The VeriFactu regulation requires your invoicing software to be certified for secure, direct communication with the AEAT (Spanish Tax Agency). If you use Bilteo or a proprietary web system, I develop the necessary API connector to ensure your system is fully compliant.

I guarantee that your invoices are communicated to the Tax Agency automatically, securely, and on time, saving you from penalties and giving you the peace of mind of being in full legal compliance without disrupting your business processes.

Web Application Development

Powerful software accessible from any browser.

Forget about installing programs on every computer. I develop centralized and secure web applications that your team can use from anywhere. From admin dashboards to complex booking or inventory management systems. I use modern technologies (Django, React, etc.) to create fluid, fast tools designed specifically to solve your company's unique workflows.
