Arvin Laurent Marron
Automation Specialist & Full-Stack Developer
I connect the tools a business already uses, like Make.com, n8n, Airtable, Notion, and Slack, so repetitive work runs on its own. When those tools aren't enough, I build full-stack web apps with React, Next.js, and Laravel, backed by MySQL or PostgreSQL. I also secure and maintain live production systems. I'm a developer based in Urdaneta City, Philippines.

About
Who I am
I'm a freelance automation specialist and full-stack developer based in Urdaneta City, Pangasinan, with a background in Computer Science at Saint Louis University, Baguio.
I build automation systems that connect the tools businesses already use, like Make.com, Airtable, Notion, Slack, and Gmail. This lets repetitive work like client onboarding, data entry, and team routing happen automatically instead of by hand.
The difference with my work is that I can actually code. When those tools hit their limit, I switch to custom scripts and APIs to get the job done. I've also delivered real full-stack projects, from a responsive product website to securing a live, heavily used transaction platform where I removed critical vulnerabilities, added backend access controls and prepared statements to stop SQL injection, and documented every step.
I work across the web stack with PHP, MySQL, JavaScript, React, Next.js, and TypeScript, and I care about writing secure, reliable, readable code. I'm always learning something new.
