Work Experience

Freelance Developer

2015 - PRESENT

JavaDB

Created the payment module for an eCommerce site (for football trips) using AngularJS.
Developed an app/cloud server to manage laser devices. These laser devices play patterns on regular intervals to repel birds. The cloud server is used to save all the setup details of these devices and CRM data of all the clients. For this we are using Node.js, Ionic 2, and PostgreSQL. I also managed the hosting on Heroku.
Built a bicycle app to motivate people to move out of their cars and get on their bikes. This app uses technologies like GPS tracking, geofencing, push notifications, and data analysis. All was setup by me using Node.js, Ionic 2, and MySQL. The hosting is managed by me on dedicated servers.
Supported the Whires application (https://app.whires.com) that was built during my employment at Netwerven/Endouble.
Built a network of possible clients using my own personal network and external network sources.

Technologies: Python, Ionic 2, AngularJS, Angular, MySQL, Java, Node.js

CTO | Senior Developer

2012 - 2015

Netwerven | Endouble

Managed and was responsible for all IT-related stuff including: hosting, development environment, hiring, and more. This company builds recruitment sites for major companies (like booking.com) and had all their development out-sourced when I entered the company. As such, I needed to set up a developer-friendly environment and started hiring developers (WordPress, PHP, HTML, CSS).
Acted as the first technical contact person on technical issues for all our clients.
Built the recruitment application (from scratch) using Node.js and AngularJS. This application combines recruitment data with Google Analytics data to show the full path from visiting the site until being hired. This application makes it possible to get a clear picture what works and what doesn't work on the recruitment site.
Integrated the application with Piwik and Google Analytics data using APIs.
Introduced a full text search on CVs using Node.js and Elasticsearch.

Technologies: MySQL, PHP, Angular, Node.js, Java

CTO | Co-owner

1999 - 2011

Connexys

Started the business and wrote the first few versions of the application (corporate recruitment management tool) by myself (including hosting and database management). Everything was created using Oracle Developer tools and PL/SQL.
Extended the application using Java tools to interface with external APIs on psychological tests/assessments, and included a full-text search on the CVs.
Became a CTO with (in the end) 10+ developers.
Transformed the application to a JSF/ADF Java application. This included CI tools, training, and complete rewriting of the application. We also got help from an external company.
Conducted more interfacing with external APIs to be able to post jobs to external sites.
Created a version 3 of the application using the Play Framework (Java).
Acted as the first technical contact for the customers and deciding upon business related changes (as co-owner).

Technologies: Oracle RDBMS, Java

Experience

Task Management Demo | API Server

https://github.com/rmoolenaar/task_management

An open-source task management application deployed on Heroku and visible at https://javadb-taskmanagement.herokuapp.com. The code sample is a generic module to create a standard RESTful API from database models using just a few lines.

Recruitment Application | Whires

The recruitment application Whires is currently used by several big clients, including a big insurance firm, Nationale Nederlanden.

This application needs to conform to the highest security standards, including a password expiration after 90 days, secure API, and more.

This app that I supported while working at JavaDB is built using Node.js and AngularJS (v. 1).
