About

Hi, I’m Adolfo Bastardo, a Senior Full-Stack Developer based in Madrid. I’ve spent 8+ years building scalable web applications and optimizing performance, delivering high-impact solutions across eCommerce, fintech, and healthcare domains. My work has helped businesses move faster and scale to handle thousands of daily users, with notable improvements like up to 40% faster app performance and robust systems serving 10K+ daily active users.

I’m comfortable across the stack—from PHP/Symfony and Python/Django to modern JavaScript frameworks like React/Next.js and Node.js—and I enjoy solving tough integration challenges, data visualization, and API design. I thrive in collaborative, cross-functional teams and love turning complex requirements into maintainable, well-tested software.
