About Me
Passionate about creating high-quality software
With over 5 years of experience in software development, I specialize in creating scalable software with good coding practices. I have extensive experience building mobile applications, web apps, and APIs, and I'm currently also using AI tools to improve workflow and productivity.

AI in my Workflow
AI Coding, not Vibe Coding
I integrate AI as a central part of my development workflow, with an approach that goes beyond vibe coding. Before writing a single line, I plan the solution, define the implementation plan, and we work step by step: I review and validate every advance. Project knowledge, quality criteria, and architectural decisions always remain mine.
Faster Deliveries
I eliminate repetitive tasks and automate build pipelines, freeing time for what actually generates value.
Enhanced Code Reviews
I built my own assistant to review my PRs before submitting them, catching improvements before they reach the team.
Custom-Built Tools
I developed custom skills and a Karpathy-style LLM wiki, tailored specifically to my own workflows.
Always My Own Judgment
I plan the solution first, then refine it with AI. Never code without a plan: I work in steps and validate every advance.
