About Me

Hi! I'm Karl Macadangdang, a Full-stack Software Engineer currently based in Las Piñas, Metro Manila.

I began my programming journey during college, starting with PHP and MySQL. Later, I joined the Research & Development Unit of the College of Computer Studies and Systems at the University of the East, which led me to explore more tools like Laravel, Node.js, React.js, React Native, andMongoDB.

Currently, I'm working at a company where we use Angular, C#, andSQL Server to maintain and improve legacy web applications. For newer projects, we use React.js, Next.js and MongoDB to build modern, scalable solutions.

Development Stacks

I have experience with multiple dev stacks — one from my college projects, and two that I've used at work.

My first stack ran from 2012 to 2021, built around PHP, Laravel and CodeIgniter with MySQL behind it and jQuery on the front end. Since joining Longares Global Operations in April 2021 I've worked across two more: an older one for maintaining legacy systems in Angular, C# and SQL Server, and a modern one built on React.js, Next.js and MongoDB for newer projects.

The stack I reach for in my own personal and freelance work is TypeScript end to end — Next.js on the front, Node.js or Nest.js behind it, and Prisma ORM over MongoDB or PostgreSQL.
