ABOUT ME

Hi, I am Olawale Olufisoye, a Senior Full-stack Engineer with over 4 years of professional experience delivering scalable fintech, POS, and enterprise applications. I specialize in Angular (v12–19), React, Node.js, and TypeScript, building robust web applications and backend services used by thousands of users.

At CHB Technologies, I led the redevelopment of a POS system, introduced TypeScript standards for backend projects, and built APIs from scratch to integrate with legacy databases like Firebird SQL. At TechBango Corporate Services, I enhanced ERP systems with Python automation and mentored interns, guiding them in modern web development practices.

Beyond my professional roles, I have delivered responsive web applications using modern frameworks and cloud platforms including Docker, AWS, Firebase, Netlify, and GitHub Actions.

I am passionate about scalable system design, mentoring developers, and driving engineering best practices that improve development efficiency and product quality.
