About me

Bachelor in Information Systems and postgraduate student in Software Architecture with AI at Full Stack Club.

I am a Full Stack Software Developer with a Bachelor degree in Information Systems, currently pursuing postgraduate studies in Software Architecture with AI at Full Stack Club. My work bridges enterprise backend engineering with C#, the .NET ecosystem (ASP.NET Core and Entity Framework), and Node.js (TypeScript and Fastify), with modern and responsive frontend interfaces built with React and Next.js.

As artificial intelligence models write increasingly high quality code, I strategically focus on software architecture, structuring resilient systems, clear contracts, and well bounded domains. At the same time, I never stop studying code deeply and consistently use artificial intelligence throughout my workflow, confident that it sharpens my decisions and makes me an even better professional.

I apply artificial intelligence with engineering discipline and rigor, adopting agentic coding environments (Claude Code, OpenAI Codex, OpenCode, and Kiro), Spec Driven Development (SDD), and Harness Engineering. My goal is ensuring models operate under strict architectural guardrails, API contracts, and automated tests, whether applying hexagonal architecture and DDD or connecting tools via the Model Context Protocol (MCP).
