- SupertrônicaAI DeveloperJanuary 2021 - January 2024 (3 years)Built internal tools to optimize workflows and project management. Designed and implemented custom software solutions for internal process control.
- FreelanceAI DeveloperJanuary 2022 - Today (4 years and 7 months)Developed intelligent agents and custom automations for companies, integrating APIs, AI pipelines, and generative AI solutions.
- TrialPaid AIAI EngineerApril 2025 - July 2025 (3 months)As the creator and developer of TrialPaid AI, I designed an agent that accelerates trial user activation in SaaS products. It reads users’ digital “body language” in real time, detects friction points, and triggers ultra-contextual nudges through the right channel (in-app, email, Slack/SMS/LinkedIn). The agent dynamically adapts tone and messaging based on the user’s current stage while logging every interaction for continuous learning — shortening time-to-value and guiding users toward their “aha moment.”On the back end, I built a production-grade automation in Python using CrewAI for multi-agent orchestration and FastAPI for stable integrations, exposing endpoints for user evaluation, cohort simulations, and notifications. The stack is fully containerized with Docker, including tests and quality checks. The system measures impact using key metrics like trial→paid conversion, reduced time-to-value, feature adoption, and retention rates, while integrating with analytics tools (for example, PostHog / Mixpanel) to close the insights loop.
