I'm a full-stack developer from the Philippines. I build web and mobile apps and take them to production. Recent ones have been for a coffee shop, an aviation company, a fitness app, and a government agency.
Hi, I'm Linus
I'm a full-stack developer based in the Philippines. Right now I'm a Software Engineer at Nerve Technologies, working on MERN and Next.js apps, and I take on freelance projects on the side.
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, and NestJS on the back end, PostgreSQL or MongoDB for data, and Socket.io when something needs to be real-time.
I'm open to full-time roles and freelance work.
