I have developed countless webshops using this platform. Ranging from simple few product shops to multi store / multi brand shops and shops with a multi level marketing system behind them. Shops reaching millions of users per month were no exception. For most shops one or many platforms needed to be integrated. In my career I have integrated all sorts of third party systems with spree commerce ranging from ecommerce marketplace systems like tradebyte to enterprise class ERP systems to dynamic shipping providers.

At some point any application needs to store some data. In order to do this correctly and future proof a good understanding of relational databases is an absolute must. From the very beginning I have been deeply involved with setting up, normalizing and perfecting data storage and defining the relation between different types of data.

As a software engineer as well as a mentor, Fabian delivers a stellar performance. His in depth knowledge of ruby on rails and website architecture is unequal to other mentors on this site. I highly recommend him because he is trustworthy of your time and work. Thanks Fabian, I am so happy to have my website's emailing system fully installed and working.

Coqtail is an ecommerce agency focused on fashion and lifestyle brands. Within coqtail I manager the development of their Plug and Play system. This system has been tailor made for fashion. Customers could choose from a range of functionalities to add to their shop. A ReactJS frontend connected to the backend API. Every client has their own ERP system(s). These systems could be simply connected by a XML or JSON mapping. Third party marketplaces like Zalando, Bol.com and Amazon could be connected via a range of configurable in house integrations.

The crowd at work is a SAAS solution primarily focussed on the utility sector. The goal was a crowdsourcing solution that would take the load of customer service teams in the broadest sense within utility companies. The pilot was focussed on Qurrent and Greenchoice. Within the companies, there was a struggle to efficiently handle energy and gas meter reading validation failures. We developed a way to visually represent the data of the meter readings which resulted in a clear pattern in common failure reasons. On top of that, we developed a set of algorithms that could detect certain types of common mistakes within meter failures programmatically. Combined the system could detect 96% of common meter failure types. The system was set up in a modular fashion. This meant any type of crowd sourceable workload could be added as a module. Each individual worker in the worker pool would undergo a screening and got qualifications assigned. These could be fixing meter failures, translate french or fix complex math issues. Based on these qualifications the worker would be allowed to complete tasks in that scope. Task result quality could be tested with peer tests (another worker verifying the result of another worker), golden questions (a task of which the system knew the outcome already) and duration testing (if a task was completed faster than average any of the other QA mechanisms would be deployed earlier) I was responsible for the complete technical architecture, development strategy, development, third party integrations and client integration.

Planrepublic is an online payrolling and employee management system. The system allows company managers to create a planning within the scope of their company of division. Employees can login to the system and register for blocks on the planning takes that they have the required qualifications for the job. Hours worked by employees are tracked as well as sick days, break times, check in/out times etc. With this information the system created a payslip each month. The staffswitch function within the system enabled managers from company A to request personel from company B when required. The system would automatically bill the hours worked to the right company. I have been involved from start to finish leading the development of the system.

Harvey is a side project being developed for the EMC (erasmus medical center) focussed on eliminating common errors in health insurance declarations. Simply said there are certain rules which need to be followed when declaring procedures to the health insurance. Those rules are poorly documented. The Harvey app incorporated those rules and allows surgeons to create a declaration with ease by smart searching procedures, procedure codes or diagnosis. By intuitively displaying and enforcing the rules and limitations of their declaration the surgeons don’t have to redo their declarations when they are denied.

The Mollie payment provider integrates with as many e-commerce platforms as possible. Instead of having all the required knowledge for all platforms in house they outsource the maintenance of the integrations. Any issues on GitHub are dealt by my and new mollie features are added to the integration. This side project is ongoing but barely every requires my attention. I guess that must be a good thing :)
