Hi, I'm
Laurence De Guzman
Full-stack developer & sole systems admin — I build AI-integrated apps and run the self-hosted infrastructure (ERP, CI/CD) that keeps them online.
About Me
3 years of real-world experience. Not just from a corporate title, but from freelancing, building personal projects, and solving actual problems for real clients. I specialize in full-stack development with AI integration, from production-ready chatbots to automated scheduling and real-time systems.
Currently freelancing for an Australian Shopify client, enhancing his sneaker e-commerce store and running 20 web-scraping bots that track stock, prices, and variants across major retailers like Nike, pushing real-time deal alerts straight to his Discord.
Now working as a Sole Systems Administrator in a professional setting while continuing to freelance. Everything I know was earned by doing, and I'm looking to grow with people who take tech seriously.
