"I believe programming is the only field that grants us a true 'superpower': the ability to extend human capacity beyond its physical limits."
To me, technology is about transcending what is humanly possible—automating complex reasoning, memorizing infinite data, and executing tasks at a scale no single person could achieve alone. To wield this power effectively, I follow three principles:
- Reliability First: With great power comes great responsibility. I prioritize strict typing and testing because a "superpower" must be predictable, not chaotic.
- Observability: If you can't measure it, you can't control it. I design systems with deep visibility to understand how they impact the real world.
- Simplicity: Magic shouldn't be confusing. I strive to solve complex problems with simple, maintainable architectures.
My GitHub organization reflects my continuous improvement process:
- 📂 Learning & Studies: Competitive programming solutions and algorithm labs (Python/C++).
- 🚀 POC Lab: Proofs of concept for new tools, experimental architectures, and automations.
- 📚 Technical Documentation: Knowledge management, PDP, and advanced notes on software engineering and System Design.
