Experience
Open Banking Platform

Legal eDiscovery Platform
For the project, I helped to develop new features for the Legal eDiscovery Platform. This platform assists lawyers and their data analysts by obtaining data from numerous possible data sources, such as Salesforce, Outlook, phone systems, and more and then cleaning and transforming the data into appropriately normalized databases for automated (as much as possible) creation of reports and analysis.
Derivatives Trade Lifecycle Platform
For this project, I developed new features for a derivatives trade lifecycle platform that significantly improves trading, the derivatives lifecycle, and risk management capabilities in one of the biggest financial institutions.
Automotive Dealership Management Platform
I developed new features and maintained the existing code for a fully customized platform that manages an automotive dealership business from end-to-end.
DevOps Automation Platform Based on a Public Cloud
Here, I developed new features for the DevOps automation platform.
This project gave me a great opportunity to dive into the Angular 2 framework. It also required perfect communication skills within an international team which turned out to be the key to success.
