Computer Science Student & Developer
Building practical systems with AI and automation.
I'm a Computer Science student from Brazil focused on building, testing, and documenting practical software systems.
My projects span AI, software development, automation, algorithms, and cybersecurity, with a growing interest in understanding not only how systems are built, but how they can be evaluated, improved, and made more reliable.
I'm currently open to remote international opportunities where I can continue learning through real-world engineering challenges.
- Merlin — Multimodal voice agent integrating real-time AI with workflow automation.
- Nexus — Secure communication platform exploring client-server architecture, applied cryptography, and secure-by-design principles.
- Giro — AI-assisted financial transaction classifier combining rule-based logic with AI.
- GraphRoute — Algorithm benchmarking tool comparing BFS, DFS, and Dijkstra over a real geographic road network.
- Vidas do Campo — Interactive learning simulation built around clinical decision-making and educational gamification.
Each project is documented through case studies covering the problem, solution, architecture, technical decisions, results, and limitations.
- Artificial Intelligence — Neural networks, multimodal systems, AI APIs, and intelligent agents.
- Software Development — Practical systems, algorithms, data structures, APIs, and maintainable architectures.
- Automation — Workflow automation and AI-assisted processes with tools such as n8n.
- Cybersecurity — Security fundamentals, applied cryptography, NFC/RFID systems, and hands-on experimentation.
I'm currently exploring several directions for future projects:
- Computer Vision — Practical and experimental projects involving image processing, neural networks, and performance evaluation.
- Cybersecurity — More structured hands-on security projects and experimentation.
- SaaS & Product Engineering — Building and maintaining a complete software product end to end.
- AI & Intelligent Systems — Going deeper into neural networks, multimodal systems, and evaluating system reliability.
This roadmap is intentionally open and will evolve as I learn, experiment, and discover new problems worth solving.
