I build the engine room of the web.

Hi, I'm Lars van Teeffelen, a backend developer from Noord-Brabant. I build APIs, data models and web applications with PHP and frameworks like Symfony and Laravel: the solid, invisible parts that make a website actually work.

What I do

The parts you don't see, built to last.

Great websites need more than a pretty face. I take care of the logic, data and integrations underneath, so the front end has something reliable to stand on.

APIs & integrations

Connecting systems that were never designed to talk to each other. I pull data from external APIs, shape it, and turn it into something useful, from clean JSON endpoints to generated PDF reports.

Web applications & content management systems

Building and maintaining PHP applications and content-driven websites: data models, custom functionality, and an editing experience that keeps clients in control.

Databases & performance

Well-structured schemas and efficient queries. Data that stays consistent, and pages that stay fast as content grows.

SELECT c.name, COUNT(o.id)
FROM customers c
JOIN orders o ON o.customer_id = c.id
GROUP BY c.id;

Support & maintenance

Live websites need care. I pick up client service tickets, track down bugs, and ship improvements that keep platforms healthy long after launch.

Writing code, from hobby to profession: 8+yrs
PHP frameworks & content management systems in my toolbox: 4
Languages spoken: Dutch, English & German: 3
Saved by finishing my degree on the accelerated track: 1yr

Experience

8+ years of turning requirements into reliable software.

From internship projects pulling data out of external APIs to building and maintaining production platforms at a full-service internet agency. I've worked across the whole backend: architecture, databases, integrations and day-to-day support.
