Data Architecture and Governance
Year 2020
RiskNow: a lakehouse under a portfolio-monitoring product
Lake, warehouse and lakehouse we designed, with rollout and ELT, over three years and four months. Around that architecture sat the portfolio-monitoring product itself and every deployment and support operation it depended on.
Year 2012
Empresômetro: watching a country open businesses
A public monitor of the businesses being created in Brazil, published in real time. Company formation read as an economic indicator rather than as registry trivia.
Year 2011
Lupa no Imposto: the tax inside the price
A service that lets anyone look inside a price: how much goes to the merchant, how much to the government, and what the product would cost with no indirect tax embedded. It was one of the drivers of Brazil's tax transparency law.
Year 2005
Impostômetro: a country's tax collection, in real time
A live counter of every tax collected in Brazil by the union, the states and the municipalities. The innovation is tempo: collection published continuously rather than quarterly, which is what turned a statistic into a national reference.

AI Culture and Operations
Year 2026
DDC Framework: a metamodel for AI-assisted engineering
A metamodel for AI-assisted engineering, grounded in Domain-Driven Design: four layers of doctrine (business, product, engineering, operations) that an agent reads before it writes, with 18 imperative rules, 9 modelling contracts, decision records and verification gates it has to pass before work counts as done. It governs data pipelines and machine learning as well as product code. This system is built inside it.
Year 2024
Liquid AI: LGPD, GDPR and a company-wide AI-first culture
Mapping LGPD and GDPR into a written security and privacy framework, governing the data pipelines beneath it, putting agents into the critical workflows, and making AI a habit across the whole company rather than a pilot inside engineering.

Vibe Coding and AI-Based Products
Year 2026
Yala: multi-agent workspaces inside Google Sheets
A Google Workspace add-on that turns a spreadsheet's own structure into an agent workspace: tabs, rows and cells become agents and tasks, orchestrated by an LLM. Conceived and built solo, pricing and Marketplace compliance included.
Year 2026
Silv.IA: multi-agent analysis from one natural-language question
A multi-agent system that takes one question in plain language, fans it out to several LLM-powered agents for churn, upsell and data analysis, and ends in an action (an e-mail or a Discord notification) with no code written.
Year 2026
AI Reporting: Trello, an LLM and SLAs in a spreadsheet
Automated synchronisation of Trello cards into Google Sheets, enriched on the way by an LLM that classifies the phase, summarises the comment thread and monitors the SLA.
Year 2026
MaranataClub: an end-to-end generative AI pipeline
A full-stack platform where generative AI is the production line: Whisper for transcription, GPT for study material and quizzes, DALL·E 3 and Leonardo AI for illustration, and an Immersive Mode that syncs all of it to the audio in real time.
Year 2019
Trackmob: BI and AI products for 100+ non-profits
Greenpeace, Doctors Without Borders, the ICRC and ActionAid used the BI and AI products we were accountable for. So did more than a hundred other non-profit organisations, across the acquisition, engagement and analytics line.
Year 2014
Nossa Causa: an agency turned into a service portfolio
More than 70 services with a named scope, a named deliverable and a price, the processes behind them drawn in BPMN, and a content operation on the agency's own account that Resultados Digitais ranked second in Brazil.
Year 2013
Eleições Limpas: automatic signature validation against the TSE
The first popular-initiative petition tool in Brazil to validate a signer's data automatically against the TSE, the electoral court, at the moment of signing rather than months later during verification.
