Field Record
Apr 2025 — Present
Tech Lead & Full-Stack Developer
Computer Engineering and Systems Laboratory — Federal University of Ceará

Technical leadership of an ERP system for project management at LESC as an EMBRAPII unit, replacing manual spreadsheet-based processes with a decoupled, scalable architecture. Built the financial simulation module for project prospecting — with approval workflows and result persistence — and integrated digital signature support for research grant activity reports.

Engineering end-to-end digital solutions for the public sector — from AI-powered prototypes and secure APIs to cross-platform applications — to validate innovative ideas and transform public service delivery. One of them is CNH Popular, a pixel-art educational game whose interactive phases guide citizens through each step of the state's subsidized driver's-license program.

§ 03About Me

Profile

I came to engineering through architecture and design — which is why I care less about shipping features and more about whether a system can actually be understood.

My journey in technology is dedicated to transforming public services through code. As a Full-Stack Developer at ÍRIS — Government of Ceará’s Innovation and Data Lab , I engineer end-to-end digital solutions—from AI-powered prototypes to secure APIs—to modernize public service delivery.

Previously, I directed the development of the Ceará sem Fome Platform , where I built a unified design system, data management interfaces, and analytics dashboards to support food security efforts for vulnerable populations.

My interdisciplinary background combines Systems Analysis and Development with Architecture and Urban Planning and graphic design. This unique perspective allows me to blend technical precision with visual sensitivity, creating applications that are not only robust and scalable but also intuitive, accessible, and human-centered.
