Plenário Virtual — Emergency Gov Voting Platform

Tribunal de Contas do Estado de São Paulo (TCE-SP)

GovTech

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.

REGIN — Integrated Company Registration

ProSolution (PSCS) — Brazilian Boards of Trade and municipalities

GovTech

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 across Brazil.

PlayEduca Disney Edition

Escola 24 Horas (Disney-licensed)

EdTech

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.

Impact

Reached more than 100,000 children (client-reported), developing the literacy and numeracy skills pre-school children need.

Lionsgate Content Recommendation Engine

Lionsgate (via BairesDev)

AI/ML

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 Defense Infrastructure

Brazilian Navy / Ministry of Defense / COPPE/UFRJ

Enterprise

Challenge

The Brazilian Navy operated with disconnected legacy systems for parts cataloging, warship logistics, and financial management across dozens of military commands.

Solution

Architected three mission-critical systems: SINGRA (supply catalog), SISALI (warship logistics), and DFM-BI (cross-command financial dashboard).

Impact

20+ years of uninterrupted mission-critical service across all naval commands.

BeyondRisk AI & Data Lake Platform

BeyondRisk

AI/ML

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 builder.

Impact

Real-time analytics pipeline processing cybersecurity events at enterprise scale. AI-powered insights reducing analyst workload and accelerating threat response.

Newsela Content Intelligence System

Newsela (via BairesDev)

EdTech

Challenge

Solution

Built ML-powered microservices using content similarity analysis and clusterization to intelligently match articles to student reading levels and interests.

Impact

IEGM São Paulo Transparency Dashboard

TCE-SP / São Paulo State Government

GovTech

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.

Impact

First unified public accountability tool for the 644 municipalities audited by the Court, enabling citizens and journalists to hold local governments accountable.
