Projects

NeoDogma — Educational SaaS Platform

Interactive app + Teacher panel | Secondary school | Region of Murcia

🏆 EduCaixa Bridge Call Award 2023 — €25,000

The problem: Secondary school teachers needed a tool to manage gamified interactive content directly tied to the official curriculum, without depending on third-party platforms.

What I built: Educational Unity/WebGL game with curriculum-adapted content, combined with an ASP.NET MVC management panel with multi-role auth, class-level activity control, progression tracking, and CSV analytics export.

Result: System live in multiple secondary schools in the Region of Murcia since 2022. EduCaixa Bridge Call Award 2023 (€25,000).

FlowHub — Multi-Tenant SaaS Platform

ASP.NET backend + CRM + Document signing | Production

The problem: Multiple client applications needed to share business logic, authentication, and persistence without duplicating infrastructure.

What I built: Multi-tenant ASP.NET Core backend with Clean Architecture centralizing tenant-aware business operations, powering two Next.js apps: a CRM and a contract generation system with document signing and n8n workflow automation.

Result: System deployed in production with Docker on VPS, actively handling CRM and document-signing pipelines.

About

I came to software development from a communication background — which gives me perspective to understand the real needs behind every system: who uses it, how, and why.

I work primarily with ASP.NET Core and Clean Architecture, focused on systems that need to hold up in production: multi-tenant, with real business rules, deployed on VPS with Docker. NeoDogma has been live in schools since 2023.

I integrate AI into my development workflow as a structured building tool — not to generate code I don't understand, but to iterate faster on architectural decisions I do control. I also work with n8n for process automation and operational pipelines.
