I'm a full-stack developer from the Philippines. I build web applications and take them to production. Recent work spans hospital and accounting systems, government HRIS platforms, and e-commerce for real businesses.
Hi, I'm Linus
I'm a full-stack developer based in the Philippines. Right now I'm a Software Engineer at Nerve Technologies, and I take on contract work on the side, building web platforms for clients across a range of industries.
Most of what I build is product and client work that ends up in production. I move around the stack depending on the job: React and Next.js on the front end; Node, Express, NestJS, and Laravel on the back end; PostgreSQL, MySQL, or MongoDB for data; and Socket.io or Convex when something needs to be real-time.
I'm open to full-time roles and freelance work.
