Full Stack Developer with professional experience building backend applications with C#, .NET 9, ASP.NET Core, Dapper, MySQL, PHP, and Laravel, as well as frontend applications with Angular 19, Next.js, React, and TypeScript.

I specialize in developing REST APIs, transactional domain modeling, multi-tenant architectures, authentication, authorization, tenant isolation, database migrations, and complex business logic using Clean Architecture. In my personal projects, I have delivered a CRM with 9 operational fronts, a financial system with atomic transfers, a clinical SaaS for physiotherapists, and an open-source SVG widget engine for GitHub READMEs.

An open-source TypeScript engine to generate dynamic SVG widgets for GitHub READMEs—including stats, streaks, languages, and activity graphs—with a unified theme system and hybrid delivery through an API and GitHub Actions.
