I am a Fullstack Engineer with over 10 years of experience, having worked across multiple industries including e-commerce, insurtech, fintech, and EdTech.

My core technical stack includes Ruby on Rails, Python (FastAPI/Flask), React/Next.js, and AWS. Over the past few years, I have accumulated 4+ years in technical leadership roles, which strengthened my product vision — especially regarding scalability, observability, and modular architecture.

I have 2+ years of hands-on experience in fintech, focused on high-risk solutions, where I continuously study and implement complex systems.

Currently, I work as Tech Lead at M3 Lending (fintech), where I develop with FastAPI, Flask, Next.js, React Native, and manage infrastructure on AWS and Heroku. Our projects operate across multiple continents and include 50+ integrations with banks and financial partners.

In recent roles, I have designed, developed, and maintained Ruby on Rails applications in production, built data pipelines using Python (Pandas), and delivered analytical dashboards that directly impacted commercial teams. In parallel, I am the creator and maintainer of SaaS products and open-source contributions:

• MeBook — AI-powered audiobook platform (100% AI-generated books) built with Ruby on Rails + Azure + Kokoro API + Gemma 3
• MeLead — CRM developed in 2024 (Rails + ViteJS) with over 300 active users
• Comitante — Podcast about software development and tech careers
