ABOUT CECILIA DE SOUSA
I’m a software engineer with a unique blend of technology and communication expertise. Since transitioning into tech in 2020, I’ve focused on creating intuitive, high-impact digital experiences, optimizing user onboarding journeys, and driving conversion through user-centered design, experimentation, and observability.I specialize in front-end and full-stack development, working with technologies like TypeScript, React, Next.js, Vercel, CSS Modules, Playwright, Optimizely, Honeycomb, Node.js, GraphQL/Apollo, Jest, Testing Library, Cypress, SQL, and Git Flow.Mentorship and inclusion are central to my approach: I actively support junior and mid-level engineers through technical guidance, pair programming, and career development.Before tech, I spent 10 years in communications and marketing, working with companies and NGOs in education and technology.Portfolio on GitHub: https://github.com/cecisousa
