My name is Evert, and I’ve been a Web Developer for 15 years. I’ve been doing consulting for a wide range of companies, from small businesses to telcos, financial services and national broadcasters.
I’m especially interested in API design, implementing better engineering practices, scalability problems and application architecture. I served as CTO or technical leadership in most of the companies I’ve worked at.

Technical Lead at Yelp, Toronto/San Francisco - 2016-2018
In October 2016, I joined Turnstyle, a company in Toronto that does location- based marketing analytics.
My role there was to help drive the design and architecture of a REST API. We’ve used HAL, OAuth2, json-schema to drive the hypermedia API using NodeJS, ES6, ES7. On a docker-container infrastructure running on Amazon Web Services. I also helped mentor other developers, and act as a technical lead.
In April 2017 Turnstyle got acquired by Yelp, and I subsequently moved to San Francisco in October.
Although my role hasn’t changed that much, I helpbed onboard a quickly growing development team, and working with the needs and requirements of a much larger corporation, including integrating our existing systems and culture with Yelp’s.
Co-Founder/CTO fruux, Germany + UK — 2011 - 2015
In December 2011 I went full-time with fruux, which was a bit of a side-project at the time. We got a seed investment round, and opened the door to our office. As the technical lead I’ve been responsible for the technical and product direction, as well as leading the team from a technical perspective. Aside from that I’ve also got my hands dirty in some marketing and sales, and basically just stepped in where needed.
As a programmer I helped develop their synchronization system for personal information such as calendars, contacts and files. I acted as a liaison for the CalConnect calendar and scheduling standard consortium.
Consulting, worldwide — 2003-today
I originally incorporated at age 17 at the Chamber of Commerce in the Netherlands. I’ve been a consultant and freelancer pretty much at any point in my career where there’s gaps between jobs.
I’ve had the opportunity to work in telecommunication, social media, group ware, advertising, broadcasting, financial service companies in Australia, Portugal, Canada and The Netherlands, and remotely worked for various other companies from North America, Europe and Asia.

Lead architect/owner, Filemobile, Toronto, Canada — 2006-2014
After working with Filemobile as a contractor, I took on the job as lead architect. Being the first person on the payroll, I was given the task of making both the application and business scalable by hiring and managing new engineers and putting development processes in place. For Filemobile, I developed a scalable social network and user-generated content whitelabel engine, working with Canada’s leading media brands such as CBC, CTV, Fox, TSN, CP24.
In this job I worked with PHP, complicated multi-master, MySQL setups (with geographic redundancy), Memcached, Amazon S3 and EC2 and I was responsible for developing a multi-core, multi-machine transcoding engine as well as leading the development team. Starting August 2009 I resigned as lead architect to continue my work as independent consultant, after that I was still involved as in an advisory role and owner.
In late 2015 the company was sold to NewZulu, an Australian-based media company.
Senior Web developer/partner, Collab, Utrecht, the Netherlands — 2004-2006
Together with Collab I’ve got a taste of many experimental innovative software, such as real-time, multi-user rich internet applications including web video chat and media conversion. Using technologies such as Flash Communication Server (now Flash Media Server) and FFMpeg. In these 3 years I’ve worked with Dutch media and internet companies, such as NOS, BNN, Telegraaf/Speurders.nl, EasyConcepts, Netmasters and UDC/Dancevalley.
Application developer/Sys admin, V/d Veer, Surhuisterveen, The Netherlands — 2003
Developed and implemented a car inventory and lease database. The Database was based on Interbase, the front-end was built using Borland Delphi. I got this job as an intern, and I was forced to jump in and learn many technologies that were new for me at the time, such as SQL.
Junior sys admin/Tech support, Microdesk, Rijswijk, The Netherlands — 2001
This job involved many system administrator tasks, such as working with hardware, installing and preparing massive amounts of desktop machines and occasionally getting coffee for the more senior people in the company.

Since 2007 I started working on an open source library that would be named sabre/dav. This project spawned a number of PHP libraries that are now widely in use for various purposes. The project site is http://sabre.io/. I’m still the lead maintainer for all of these projects.
