A modular, AI-driven set of business applications over a shared data layer.
Ledgi is MZ Unlimited's own product line, at an early stage of development: modular business applications that share one data layer and AI-driven workflows. The first module, Ledgi Start, is in use for MZ's own invoicing; further modules are being developed from internal use toward commercial release.
Ledgi Tech is a brand of MZ Unlimited LLC.

A learning world for children aged 3 to 6: games, narrated lessons and progress reports aligned with Brazil's BNCC curriculum.
Amazing Wise Friends (Amigos Super Sabidos) began at Arcolabs as a studio title helping children learn to read, write and do basic mathematics, and was presented at XDS 2017 and 2019 in Vancouver, Game Connection Europe 2017 and Gamescom 2018. Its second version is an educational platform delivered through partner schools: families join through their school, children play in a web browser or tablet app, in Portuguese or English, and parents follow every step in simple reports.
Unlimited Studio and Amazing Wise Friends are brands of MZ Unlimited LLC.
Visit ultd.studioActivities follow the fields of experience of Brazil's early-childhood curriculum, in three age bands: 3–4, 4–5 and 5–6.
Short games and read-along lessons, each led by a character who guides one area of learning.
Free for families through their school, with no ads or in-app purchases; parents follow progress in clear reports.
Deep dives
Landmark projects with Challenge, Solution, and measurable Impact — the same accounts as on the home page.
Tribunal de Contas do Estado de São Paulo (TCE-SP)
Challenge
COVID-19 halted in-person sessions in April 2020. Under Resolução nº 02/2020 the Court needed a session, voting and agenda system to keep deliberating on the public spending of the 644 municipalities it audits.
Solution
Designed and delivered the session, voting and agenda system that supported the Court's emergency videoconference sessions — session management, electronic voting and role-based access.
Impact
85 remote sessions held during the pandemic, keeping the Court's oversight of the 644 municipalities running.
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.
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: all 92 municipalities of Rio de Janeiro state (2022), 144 in Pará and 279 in Bahia (2026), more than 100 in Pernambuco (2023); 250 Santa Catarina municipalities by 2009, with 676 municipal servants trained.
Escola 24 Horas (Disney-licensed)
Challenge
Brazilian schools needed engaging, curriculum-aligned digital learning that could genuinely compete with entertainment for young children's 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 — as lead architect and head of development, leading front-end and back-end teams of 32.
Impact
Released in August 2019; reached more than 100,000 children (client-reported), developing the literacy and numeracy skills pre-school children need. Acquired by a national educational group in 2022 (client's account).
Lionsgate (via BairesDev)
Challenge
Lionsgate's streaming platform had low content discovery rates and poor user engagement — manual curation couldn't scale to match catalog size.
Solution
Engineered high-performance ML recommendation APIs analyzing viewing patterns, content metadata, and collaborative signals via Python + FastAPI on AWS.
Impact
Measurable improvement in user engagement metrics. Personalized recommendations serving Lionsgate's full content catalog at production scale.
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 with NATO catalogue integration), SISALI (warship logistic support and maintenance, 2008–2012, as project manager), Quaestor (led six developers) 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
Assembled a team of about ten engineers and shipped the MVP in four months. Designed the full data architecture (RabbitMQ, Apache Iceberg, Spark, Trino) and built LLM-powered BI dashboards plus the AI-6 application builder.
Impact
Real-time analytics pipeline processing cybersecurity events at enterprise scale. AI-powered insights reducing analyst workload and accelerating threat response.
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 to intelligently match articles to student reading levels and interests.
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 the interactive data-visualisation dashboard computing the Municipal Management Effectiveness Index (IEG-M) for the 644 municipalities, launched in 2015.
Impact
First unified public accountability tool for the 644 municipalities audited by the Court, enabling citizens and journalists to hold local governments accountable; cited in the Court's 2018 Innovare submission.
