How I can help
Build and grow engineering teams: hiring, autonomy with ownership, and engineer development.
Architect and scale platforms: high-volume, low-latency distributed systems for e-commerce, data, and retail media.
Ship AI and machine learning to production: NLP, computer vision, and agents applied to operational decisions.
Connect technology to business outcomes: technical strategy built alongside product and operations.
How I lead
Autonomy with ownership. Teams grow when they have context, ownership, and end-to-end responsibility.
Engineer growth. I develop people through real challenges, direct feedback, and a commitment to technical excellence.
Technology in service of the business. Architecture, quality, and innovation measured by the impact they create for operations and customers.
Experience
ComDado · Founder & CTO
– present · Rio de Janeiro, Brazil
I founded ComDado, an AI-native platform that monitors an operation's vital signs, such as revenue, stockouts, margin, inventory, and receivables, and turns deviations into alerts with context, a likely hypothesis, and a next action.
I lead product, architecture, engineering, data integrations, and AI agents, from technical strategy to production code.
I design the platform to connect the sources a company already has (ERP, CRM, spreadsheets, databases, and BI) and detect deviations in near real time.
