Case study 01 / 03 · 2025

Sole front-end engineer (greenfield)

The problem. Quor sells trust: hardened container images with zero-CVE baselines, SBOMs, and verifiable provenance. Customers needed a console that makes that evidence usable — a growing image catalog to browse, dense package-level security data to inspect, and registry credentials that production pipelines depend on.

The outcome. Shipped to production with the product's public launch. From empty repo to customers' hands solo: a fully type-safe React SPA where heavy catalog and security datasets stay responsive, and credential flows are designed to be hard to get wrong.

Case study 02 / 03 · 2021–2023

Front-end engineer (multidisciplinary team)

The problem. The State of Ceará runs social programs at serious scale — Cartão Mais Infância alone reaches ~150,000 families, Vale Gás Social has served 450,000+ — but the data behind them lived in internal systems. The government needed a public, transparent window into social-protection data: dashboards for decision-makers and citizens alike, covering indicators across all 184 municipalities.

The outcome. Big Data Social became the public face of Ceará's social-protection data and a daily tool for government teams, who use its dashboards to guide program decisions. The portal today reports 119,000+ families visited across 182 municipalities and R$193M/year in tracked investment.

Full-stack engineer

The problem. SeaTech World needed a software-house presence that communicates a broad services catalog — custom systems, websites, landing pages, and e-commerce — and converts visitors into leads while signaling AI/ML credibility.

The outcome. Delivered a responsive marketing site with a services catalog, a CMS-driven blog, and multi-channel lead capture through a contact form, WhatsApp/email links, and a newsletter.
