Senior🎓
Top SchoolDaniel Kiesshau is a Senior Full Stack Software Engineer with eight years of experience building high-impact consumer and B2B products across health tech, fintech, and e-commerce. He leads end-to-end delivery from system design to CI/CD, combining React/React Native front-ends and Node.js back-ends with AWS and Kubernetes to ship scalable, production-grade apps used by millions. As a tech lead he has driven revenue-generating initiatives (e.g., an inactivity-fee feature adding +R$1M/month) and improved developer productivity and release velocity through observability, feature flags, and shared libraries. Currently focused on longevity and health-coaching platforms, he blends deep mobile expertise (Expo, native integrations, complex animations) with strong skills in data structures, algorithms, and clean architecture. He also brings hands-on experience with testing strategies (unit, integration, E2E), A/B experimentation, and product-minded engineering informed by MBA and AI leadership studies. Unusually, he pairs technical ownership with a background in entrepreneurship, enabling pragmatic solutions that balance user value and business outcomes.
