About Rebeca
Versatile and goal-oriented Senior Fullstack / Product Software Engineer with 8+ years of experience.
I help startups and innovation-driven organizations turn ideas into products, with a strong focus on business impact, user experience, and project constraints (time, budget, scope).
I’ve worked on highly scalable systems, early-stage startups, and EU-funded research and innovation projects, adapting my approach to the product’s maturity and goals.
Currently, I am the right fit for a senior engineering support role in a part-time and asynchronous setup, with a focus on outcomes.
If required by the project, I work with other fellow freelancers to support product, design, and development tasks.
