about me

15+ Years Building
Software That Scales

Hi, I'm Ben Serlippens, a senior full-stack developer and technical lead with 15+ years of experience. I specialise in integration-heavy, multi-tenant web apps built on Laravel and Symfony with React/TypeScript front-ends, and I connect products to the payment, payroll, accounting, messaging and AI systems they depend on. I work remotely and async, and take ownership from design to deployment.

What I Do

What I Do for Clients

Wire the hard integrations

My core strength: connecting your product to the messy external systems it lives or dies by, such as payment providers, payroll & accounting, messaging and AI. If it has an API (or barely does), I make it reliable, logged and testable.

Build & own web apps end-to-end

From zero to production: back-end, web front-end and mobile. A senior who takes responsibility for the whole thing, not one slice of it.

Modernise legacy PHP

Old PHP 7.x into modern Laravel or Symfony with DDD and TDD, incrementally and without downtime for your users.

Multi-tenant architecture

One platform, many isolated tenants: the pattern behind most B2B web apps, done cleanly at the database and application layer.

Technical leadership

Code review, CI/CD, mentoring and raising the bar on quality. 12+ years leading development teams.
