Ymanol Martinez Castillo

I’m a senior software developer with 6+ years of experience building scalable web and mobile platforms, automation systems, and immersive XR applications. I focus on delivering high-impact products across fintech, enterprise environments, and emerging technology.

In my most recent role, I led internal platform and automation development used across company operations. I built modern web tools with React, Nest.js, and PowerAutomate, and I worked closely with stakeholders to define scopes, requirements, and technical solutions.

Previously, I helped launch a Neobank mobile credit card application with React Native and led frontend development for a digital lending platform used by thousands of users. I also served as Technical Frontend Lead, improving architecture, code standards, and development processes, and I’ve delivered AR/VR experiences using Unity, ARCore, and ARKit—earning first-place recognition for an Augmented Reality driver education solution and leading a technical innovation team.
