Team Lead of the JavaScript Team at Up2Technology

Noteworthy projects
  • A gamified exercise app for children with bladder malfunction.Home screen of the bladder application
  • A tool for producers from the developing countries, where they could monitor and subscribe for regulations from the countries they export to. The project was backed by the UN and was later handed over to WTOA globe on focus with headphones and a camera off focus
  • An iPad UI for the dutch ambulance services that notify hospital staff in the Emergency Unit about incoming patients and their conditionHealth workers putting a patient in an ambulance

After spending time in Up2 as a lone HTML5 developer, we decided to create a Front-End team that could help the other teams with the construction of complex UIs.

We started off using vanilla JS with strict standards on the code quality and modularity.

Beginning of 2016, after doing research and evaluation of the possible frameworks (Angular/React/Emmet), we decided to start using React for our future project.

Technologies: React, React Native, Expo, Redux, SASS, D3, leafletJS, Node.js, express, TypeScript, PostgreSQL and Sequelize, GraphQL, Bootstrap, ChartJS, Sencha Touch, jQuery, Phonegapp/Cordova, Ace/Brace, etc.

CTO of Maplese B.V.

Jul 2015 - Dec 2019
  • Implementing a pilot for remote monitoring of marine vesselsA support boat parked at a dock
  • Building a monitoring solution for the dutch railroad infra supervisorRailroad workers maintaining a track
  • Creating a modular dashboard UI with configurable widgetsA dashboard with different colorful widgets on it

Maplese is an IoT tool for data parsing, visualization, and distribution. It was a spin-off from Up2Technology
Created initially as a SaaS tool for visualization of data on a map, it evolved into a version focused on devices.
After several pilots and integration, we developed a new version. It was a complete rewrite, taking into account the lessons we learned.

After the update, we enabled the developers to reuse common logic during the implementation of an IoT project, instead of writing it every time. Functionalities, such as monitoring connectivity, unwrapping binary payload from common devices, data aggregation, data storage on the gateway, and sending data to a cloud are abstracted away from the system integrator.

My work involved:

  • Creating the architecture of the end-to-end solution with the help of our DotNet architects.
  • Creating the architecture for the front-end and implementing some of the UI components.
  • Writing technical documentation, targeted towards 3rd party developers.
  • Setting up the CI/CD jobs and automating the dev environment setup
Technologies: React, Redux, D3, leafletJS, MQTT over WebSockets, Node.js, ChartJS, PhoneGap/Cordova, Ace/Brace, PowerShell, Azure DevOps (former VSTS)

Mobile HTML5 & WordPress Developer at Up2Technology

Apr 2011 - Sep 2014
Noteworthy projects
  • Application for a dutch removal company specializing in moving hospitals, laboratories, and office equipment. The app was used to calculate and book the needed resources (trucks and workers) for the removal process.Man pushing a hand truck with big cardboad boxes on it
  • UIs for a track-and-trace solution that included a web map and work/travel time slots. These were used by construction companies in Belgium to organize the salary bonuses of the employees that commuted together with their colleagues in a shared vehicle.Big commercial trucks on a dirty road
  • Application for support engineers that helps them track the tasks that need attention. It was used by one of the big airports in Europe, a construction work company, and several service companies (like fire inspectors).Airport baggage vehicles

During that time I was building HTML5 applications for a customer targeted towards iOS Safari (only major mobile browsers supporting some of the HTML5 features).

The applications were business apps developed for an enterprise app-store based on HTML5.

After the customer sold the branch that developed HTML5 apps, I started helping the WordPress team with theme development.

Technologies: HTML5, CSS3, mobiscroll, iOS Safari, WordPress
