The most amazing...
...and socially relevant eHealth project I've designed and developed was an IoT server back end for monitoring older adults using a CareWatch.
Work Experience
Software Architect, Developer, and CTO
112Motion
- Designed a scalable back end to cope with a high load of messages coming from (custom) wearable sensor devices.
- Implemented both a proof-of-concept and the production version of the project.
- Oversaw the full technical landscape and interactions between various parts (wearable, data collection and data processing).
- Designed and implemented multiple API, both internal and external to support integration with 3rd-party analytics partners.
DevOps Software Engineer and Architect
Rabobank
- Introduced an API-First approach using OpenAPI to describe REST-based services for an authorization hub.
- Created a pluggable solution to design a future proof system and make it possible to easily extend with new and upcoming authorization providers.
- Developed a CI/CD pipeline for easy deployment on Pivotal Cloud Foundry.
- Onboarded and exchanged knowledge with new and existing team members.
Software Architect and Knowledge Technologist
Ictu (Dutch Government) - Project Reva
- Designed and implemented an application for registering labor migrants used by the majority of Dutch municipalities.
- Accomplished a working solution on a minimal budget which worked for several years to the full satisfaction of end-users.
- Performed technical maintenance for several years after the project was completed.
- Build the whole application on top of a framework that was specifically created for the previous application.
DevOps Software Engineer and Architect
Rabobank
- Designed and implemented API layers for existing services. Developed Soap-based services accessible as REST services for interfacing by front-end client applications.
- Abstracted direct LDAP access with API layers to prevent the client application from directly interfacing with the LDAP repository. As a result, it was easier to restructure authorization rules without breaking existing applications.
- Set up the CI/CD by modifying the existing Jenkins build server to deploy (XL Deploy) applications on DTAP environments automatically.
- Configured XL Deploy with both deploy environments and pipelines. Using XL Deploy, we reduced operations engineer dependency for deploying the application to develop, test, and acceptance environments. This dramatically boosted our development cycle.
Software Architect and Knowledge Technologist
Ictu (Dutch Government) - Project Digimelding
- Designed and implemented a framework (AStore) for storing and retrieving annotations according to W3C Annotation specification. These RDF-based annotations were stored in an RDF database and queries using Sparql.
- Improved performance and scalability of the Apache Clerezza library to such an extent that Minto was granted commit privileges for that project. (Permitted to modify the source code of a software).
- Developed and implemented a system for reporting data inaccuracies back to the original data source/owner.
- Extended existing inaccuracy reporting applications to cope with the new "Digimelding" model.
