Über Juan Pablo

Senior Software Engineer with 30+ years in software development and 12+ years of proven remote delivery for international companies.

I specialise in building secure, scalable payment systems and FinTech solutions. At Retail InMotion, I led PCI-compliant payment gateway processing of 500,000+ daily transactions for 30+ airline clients, integrating with 15+ payment acquirers. At UpCo Technologies, I built payment solutions including Stripe Connect, Bank of Ireland integration, and subscription billing systems.

As Co-Founder at EdiEZ.Online, I've built a complete B2B platform for Electronic Data Interchange and electronic invoicing, and I've become an official AEAT Social Collaborator for VeriFactu invoice submission to the Spanish Tax Authority.

Tech stack: NestJS, Node.js, .NET Core, C#, TypeScript, Angular, Vue.js, MongoDB, SQL Server, MySQL, GraphQL, AWS, Google Cloud.

Available for remote contract work from April 2026.
