Jhonatan Caldeira is a CTO and platform engineering leader with 10 years of experience building payments and checkout infrastructure from the ground up. He combines hands-on full‑stack development (Golang, TypeScript, Next.js, Deno/Node) with systems-level expertise in migrating monoliths to microservices, CI/CD automation on AWS, and ISO 27001/PCI‑DSS security programs that delivered zero compliance incidents. At Pagou.ai he cut deployment and provisioning times dramatically, refactored legacy Node.js to modern stacks, and drove cost and performance improvements while enabling rapid marketing experiments. A former aerodesign team lead and founder, he brings disciplined project management and a knack for squeezing efficiency from hardware and cloud systems alike. Based in Santa Catarina, Brazil, he blends startup grit with formal engineering training in electrical and computer systems, often working directly with remote, English‑speaking teams.
