partialAI Enthusiast Projects
I build tools to solve my own problems—automating the tedious stuff, making workflows smoother, and turning passive learning into something I can actually use. These aren't just experiments; they're investments that help me work smarter, not harder.
ivo-cli
CLI Tool
Before Claude Code CLI and other intelligent CLIs existed, I built my own CLI tool that automated git integrations and workflow organization. This enabled me to accelerate many processes and free up time to explore new possibilities.
Custom AI Agents
Automation
I created my own AI agents that automate tedious tasks: transcribing content, interpreting tickets, generating PR drafts with suggestions on where to start, and other productivity facilitators. When Claude Code CLI appeared, it saved me from maintaining these tools—but the experience was invaluable.
Structured AI Study Process
Methodology
I developed a structured approach to applying AI in software projects, intelligently outsourcing repetitive work to AI while preserving intellectual work for human creativity. This ensures both efficiency and quality.
ivo-whisper
Learning System
Through my `@ivo-cli`, I built agents that download audio from entire YouTube channels, transcribe content, and index it into my own vectorized database with a custom hybrid RAG implementation. This helps me study efficiently from curated channels, turning passive consumption into an active learning system.
Mentorship
I offer personalized mentorship services, especially for Brazilians who want to work for global companies. This is a customized service with limited availability, tailored to each individual's career goals and aspirations.
