CTO at Fire Banking

Summary
👤
Senior🎓
Top SchoolLucas De Araújo is a pragmatic CTO and founder with eight years of hands-on experience building and leading engineering teams across fintech, political tech, and consulting engagements. He combines deep backend expertise in NodeJS, NestJS, TypeScript and cloud-native tooling with product-facing work in NextJS/React and mobile, having shipped PIX-based payment APIs and PWA/web apps under tight deadlines. As founder of Arkos and Fire Banking he has delivered for clients like BTG Pactual and Carrefour while also architecting campaign-grade systems (web, monitoring, WhatsApp automation) during a presidential campaign—demonstrating an ability to move from prototype to production at scale. Lucas pairs technical leadership (code review, architecture, CI/CD, queues) with people management—recruiting teams, running 1:1s and PDIs—to drive both delivery and developer growth. Based in Ceará, Brazil, he blends polyglot experience (PHP, Python, Java, C) with a builder’s mindset and an eye for cost-optimizing infrastructure. He’s equally comfortable bootstrapping new products and stabilizing legacy systems, and often turns cross-disciplinary constraints into practical, measurable solutions.
