Bitcoin onboarding - release of a comprehensive documentation

ChrisYoon April 17, 2025

Bitcoin is not only a highly fascinating rabbit hole, it is also a huge white pill that gives me hope for our future. In recent years I was frequently asked by friends and clients to help them implement a Bitcoin setup. Before I implemented the setup I tested the entire onboarding process on my own devices and documented the main steps. In doing so, I created a documentation that gives an overview of the main advantages of Bitcoin and discusses different risk scenarios, solutions for key storage and other security considerations.

ChrisYoon July 9, 2024

Just recently I completed a desktop app for Signum News that allows us to organize our data management process at the business level. The high level functionalities of the desktop app include the management of data sources, the control and monitoring of data crawling jobs, data processing and editing as well as data quality management.

Release of new website

ChrisYoon June 4, 2024

This is it! I'm excited to announce the launch of my new website! Over the years, I relied on a simple WordPress website for my portfolio, as it was convenient and sufficient while working as a 9-5 software engineer and data scientist. With no urgent need for a personal online presence and limited web development skills, it served its purpose. However, things changed in recent years and I dived deeper into web development. As a Python programmer, I naturally turned to Django for the task, which proved to be an incredibly powerful library.

Data architecture and GUI in the real estate industry

ChrisYoon April 2, 2024

A common problem of businesses in all kinds of industries is the integration of data from different sources into a central database. In one of our recent projects we built an entire data architecture from the scratch for a real estate company. The data architecture included an ETL-pipleline extracting and processing data from APIs and data entry masks, a central database plus a web front-end that allows users to manage the data pipeline and interact with the database - a simple but effective architecture.

Medical mobile app for Mobimed

ChrisYoon September 15, 2023

This week I completed my first Android mobile app project for the medical patient management software company MobiMed. The app was written in Python Kivy and serves as an extension for a browser-based patient management software. The app allows users to search for patients, take photographs, record and play audio files, save the files on the phone or upload the audio files and pictures to the patient file on a server.

Recommendation system for streaming platform completed

ChrisYoon March 2, 2023

In recent days I finalized one of my first large exciting projects since I founded my own company, which was the development of a recommendation system for a podcast and music streaming company. Recommendation systems are a common machine learning application, which allow content providers to curate and suggest content to users based on their preferences.

Web crawler and price algorithm for tourism company

ChrisYoon May 27, 2022

When it comes to data crawling Python Selenium can be a good choice to crawl data from Javascript websites, which are non-static and require the crawler to navigate through the website. In other words, Selenium allows you to transform your webbrowser into a robot - a tool that can be used in many use cases such as site maintenance, performance analysis, or data crawling. One recent use case for such a browser bot was a data crawler for an Irish tourism company, which allowed the company to extract data from Booking.com and calculate price changes.

Automated industry classification system for business data company Herold

ChrisYoon January 10, 2022

As part of my last projects for an Austrian business data company I developed an automated industry classification system. One of the main problems of the company's database was that the categories and the taxonomy of the industry groups were messy and unstructured. Additionally, for a large chunk of the data the categories were missing. So, the goal of the project was to automatically classify business data into their respective industry categories and to automated the process using a neural network and an automated data stream.
