The following is a list of projects I have worked on or am currently working on.
A boilerplate-free Scala library for loading configuration files written in
HOCON, Java .properties or JSON. I started contributing to the
project in 2016 and am now one of the maintainers.
LeetCode is an online platform providing coding and algorithmic problems. Every now and then I solve problems there.
A Scala wrapper for SnakeYAML, providing a simple immutable model of the YAML language, built on top of SnakeYAML models, as well as type class based (de)serialization of custom objects.
Advent of Code is an advent calendar of small programming puzzles. There were years in which I solved the problems in Scala (2015, 2016, 2017, 2020, 2021, 2022), two years in which I solved them in C++ (2019, 2023) and a year in which I dabbled in multiple programming languages (2018).
A customer data platform for first-party data collection and segmentation for audience activation and personalization, all deployed on a private infrastructure. It has been one of the projects I’ve been involved with at Kevel since 2022 (previously at Velocidi – since 2018 – and ShiftForward – since 2014).
An engine for dashboards that only requires a browser to run. It has been used to run a dashboard in ShiftForward’s office for a while. We haven’t updated it in ages, but might be able to give support to it if the need arises.
A plugin for beets to fetch genre information from rateyourmusic.com. It’s written in Python, using lxml and requests. rateyourmusic.com doesn’t allow access via scraping or scripts which accesses the site in an automated fashion, so you should refrain from using this until they complete their API. I might revive the project once that goes live.
A forecasting engine for online advertising campaigns. It aims to accurately predict future ad impressions traffic levels and campaign inventory availability using an unlimited number of targeting variables. It has been one of the projects I’ve been involved in since joining ShiftForward (now Velocidi) in 2012.
A mobile application to monitor the risk of falling while actively reducing it through dancing exercises. I developed some signal analysis tools for it, while at Fraunhofer AICOS.
A mobile application to promote mobility among elder people. I designed and developed a new version which allowed for data to be stored and analyzed remotely, while at Fraunhofer AICOS.
A YAP module to provide an interface to R in the Prolog engine. I’m not sure if it still works, so use at your own risk.
