BigData developer & data scientist for automotive customer
Spielraum UG
(Internet and Information Technology, < 10 employees)
Big Data Platform for Vehicle Fleets
Big Data and IoT enable the collection and analysis of large amounts of data generated by sensors in a vehicle fleet. The platform can visualize and analyze time series and data points from various vehicle sensors on a map in real-time. It can be used to improve the efficiency and safety of the vehicle fleet and applied in fields such as urban services. It also allows for predictive analysis to plan and optimize future maintenance needs and costs.
As a web developer and software architect, I developed a research prototype of a Big Data platform in ReactJS that processed vehicle data with NodeJS and DynamoDB in the AWS Cloud. The platform could access a very large amount of data efficiently and present it in real-time in a web dashboard. Additionally, AI models were integrated to perform calculations based on the data. The map visualization also allowed for the evaluation of the road condition and traffic situations to enable optimized traffic planning.

Fintech startup founder & developer for pipmyday.com
Pipmyday UG
(Banks and financial services, < 10 employees)
Pipmyday - Data Analysis Platform for Forex Trading
Forex trading is a market where currencies are traded. To be successful, traders need to constantly track market movements and trends to identify profitable trades. A data analysis platform can help by providing real-time data and assisting in the analysis. By using data analysis tools, traders can make decisions based on data, instead of relying on guesses or gut feelings. This can help minimize the risk of mistakes and ultimately achieve better results.
For the startup Pipmyday, I worked on the development of a data analysis platform for Forex traders. The platform provides users with a real-time data analysis dashboard, giving them accurate and up-to-date information about market movements and trends as well as the performance of currency pairs. To develop this system, I employed various technologies including Python, C++, S, Docker, MeteorJS, NodeJS, Streams, Big Data, MongoDB, and Redis.
The dashboard enables users to create their own indicators and trading strategies and integrate them into the system to make data-driven decisions. The use of big data technologies allows for the analysis of large amounts of data in real-time to provide users with accurate and up-to-date information. The system was designed to offer users a seamless and user-friendly experience.
