Deep dives
Landmark projects with Challenge, Solution, and measurable Impact.
TCE-SP (São Paulo State Court of Accounts)
Challenge
COVID-19 halted in-person court sessions, threatening oversight of the public spending of the 644 municipalities audited by the Court with no existing digital alternative.
Solution
Designed and delivered a secure web-based voting platform — with session management, electronic signatures, and role-based access.
Impact
Maintained uninterrupted oversight of the 644 municipalities audited by the Court through the pandemic.
ProSolution (PSCS) — Brazilian Boards of Trade and municipalities
Challenge
Company incorporation in Brazil took five to six months due to fragmented, paper-based bureaucracy across multiple disconnected government agencies.
Solution
Built an integrated digital platform unifying state, municipal, and federal agencies into a single streamlined workflow with automated validation and real-time status tracking.
Impact
Incorporation time cut from five to six months to about 60 days. Present in more than 1,000 cities and nine Boards of Trade across Brazil.
Escola 24 Horas (Disney-licensed)
Challenge
Brazilian schools needed engaging, curriculum-aligned digital learning that could genuinely compete with entertainment for young children's limited attention.
Solution
Developed an educational game platform featuring licensed Disney characters, with activities by Brazilian educators aligned with the National Curriculum Base (BNCC) for pre-school.
Impact
Reached more than 100,000 children (client-reported), developing the literacy and numeracy skills pre-school children need.
Lionsgate (via BairesDev)
Challenge
Lionsgate's streaming platform had low content discovery rates and poor user engagement — manual curation couldn't scale to match their growing catalog.
Solution
Engineered high-performance ML recommendation APIs analyzing viewing patterns, content metadata, and collaborative signals via Python + FastAPI deployed on AWS Kubernetes.
Impact
Measurable improvement in user engagement metrics. Personalized recommendations serving Lionsgate's entire content catalog at production scale, continuously.
Brazilian Navy / COPPE/UFRJ
Challenge
The Brazilian Navy relied on disconnected legacy systems for supply cataloguing, warship maintenance logistics and financial management.
Solution
Delivered, through COPPE/UFRJ, SINGRA (supply management), SISALI (warship logistic support and maintenance, 2008–2012, as project manager) and DFM-BI (the Finance Directorate's dashboard).
Impact
SISALI was the Navy's first warship logistic-support and maintenance system; in 2013 the Navy's Integrated Logistics Support Bureau (NALIM) recorded Fabio as its project manager.
BeyondRisk
Challenge
A next-generation risk management company needed to transform raw, siloed cybersecurity data into actionable executive intelligence at scale.
Solution
Designed the full data architecture (RabbitMQ, Apache Iceberg, Spark, Trino) and built LLM-powered BI dashboards plus the AI-6 application development platform.
Impact
Real-time analytics processing cybersecurity events at enterprise scale. AI-powered insights reducing analyst workload and accelerating threat response time.
Newsela (via BairesDev)
Challenge
Newsela's K-12 platform needed a new content-discovery service to deliver personalized content to its teachers and students at scale.
Solution
Built ML-powered microservices using content similarity analysis and clusterization models to intelligently match articles to student reading levels and curriculum needs.
Impact
Content-discovery service deployed on a platform serving nearly 1 million teachers and 9 million students. Recommendation engine on AWS Lambda serving personalized feeds at scale.
TCE-SP / São Paulo State Government
Challenge
The 644 municipalities audited by the Court had no unified accountability dashboard — citizens and auditors couldn't compare management effectiveness or identify underperforming governments.
Solution
Built an interactive data visualization dashboard computing the Municipal Management Effectiveness Index (IEGM) across all state municipalities with automated audit scoring.
Impact
First unified public accountability tool for the 644 municipalities audited by the Court, enabling citizens and journalists to hold local governments accountable.
