Rockstar🎓
Top SchoolMicael Marques is a founder and senior software engineer with 8 years of experience building high-performance, scalable systems and leading product strategy from Brazil’s Campina Grande. As CEO of araraHQ he designed a CPaaS platform that reached PMF and scalable revenue within three months, architecting high-throughput messaging with Kotlin, Spring Boot and Project Loom while keeping the business bootstrapped. Prior roles at Creditas, ZRP and others reflect deep full-stack and backend expertise across Java/Kotlin, Python/Django, Kafka, Redis, PostgreSQL, Docker/Kubernetes and CI/CD, with strong focus on security, observability and compliance for financial systems. He’s comfortable across product, architecture and execution—having implemented billing engines, no-code routing modules with Radix Trees and DAG validation, and anomaly detection for fraud prevention. Notably pragmatic, he pairs startup traction and unit economics with hands-on engineering that turns complex integrations (WhatsApp, SES, Twilio) into reliable, automated flows.
