What's my story?

I’ve been a software engineer for over 15 years, with strong experience in backend development, distributed systems architecture, and, in recent years, applied Artificial Intelligence in real-world products. I’m the CTO and co-founder of O2OBOTS, where I built the platform from scratch as the sole engineer in the early years, leading it until the company secured investment and scaled its solutions within the financial market.

I have hands-on experience with Node.js, NestJS, AWS, microservices, messaging systems (Kafka), PostgreSQL, and event-driven architectures. In recent years, I’ve been focused on building conversational AI agents, especially for credit origination and debt renegotiation via WhatsApp, generating direct business impact in millions of reais transacted.

What makes me unique is the combination of product vision, deep technical expertise, and an ownership mindset. I’ve built systems under severe resource constraints, scaled mission-critical solutions, and made architectural decisions with real business impact.

I’m looking for a Senior Software Engineer role focused on backend and applied AI, where I can contribute at a high technical level, participate in architectural decisions, and work on products that solve real problems in an intelligent and scalable way.

Employment History

CTO & Senior Software Engineer at O2OBOTS Inteligência Artificial SA Current 2017 - Now
I serve as CTO and Co-Founder at O2OBOTS, leading the technology strategy and the evolution of an AI-driven platform focused on credit, debt collection, and conversational customer service at scale, with strong adoption through WhatsApp. In the early years of the company, I was the sole software engineer, responsible for designing and building the entire platform architecture, including backend systems, integrations, infrastructure, and conversational automations. During this period, the company grew from zero to raising R$ 4.5 million in investment and began serving major players in the financial market. O2OBOTS initially started as an automation solution for the insurance sector and later expanded into the credit industry, reaching over R$ 2 billion in credit origination and generating more than R$ 100 million in annual sales in recent years. Throughout this journey, we evolved from rule-based chatbot flows to AI-powered solutions capable of intent detection, real-time sentiment analysis, and dynamic conversation routing. Currently, I lead the launch of O2OBOTS 2.0, introducing AI Agents designed to understand context, intent, and product logic, interacting in a more natural, human-like way and requesting only the information required to complete a sale or a debt renegotiation.
