Dener Fernandes is a seasoned technology leader and current CTO based in Poznan with 11 years of hands-on software engineering and team leadership experience across e-commerce, mobile, and SaaS product development. He blends pragmatic architecture decisions with stack modernization efforts, having moved between hands-on roles (Node.js, TypeScript, PHP, Go, React/React Native) and leadership positions that guide tech strategy and team growth. His background spans both monolithic and microservices architectures and deep experience with messaging and performance tools like Redis, RabbitMQ and gRPC. Known for an open, experimental mindset, he actively explores new languages and methodologies to solve product problems rather than defaulting to trends. He also brings operational experience integrating POS, CRM and payment systems earlier in his career, giving him a practical lens on delivering production-grade, business-critical systems.
