Hello, I'm

Okiror Samuel Vinald

Computer Engineer

Vinald

I'm a Results-driven Software Developer with a Bachelor of Science in Computer Engineering, specializing in full-stack web and mobile development. With professional expertise in JavaScript (React and React Native), Python (Django), and Java, with hands-on experience building scalable, user-centric applications.

Since transitioning from academia to professional development, I've focused on bridging the gap between theoretical knowledge and practical implementation. My engineering background gives me a unique perspective on system design, while my hands-on experience allows me to create efficient, scalable applications that solve real business problems.

What drives me is the opportunity to transform complex requirements into intuitive digital experiences. Whether optimizing backend performance or crafting pixel-perfect UIs, I approach each challenge with a problem-solving mindset and commitment to clean, maintainable code.
