News Aggregation and Visualization Product

A progressive web application using cutting edge stack with rich data visualizations. I contributed primarily to the front end as well as helped with the back-end aggregation set up. I also contributed to hiring team members. All this was done in a fast-moving, high-pressure environment. We managed to secure funding for the project after the MVP was validated with users.

Payment Transaction Aggregation Platform

This platform is a payment transaction aggregation and visualization software. It aggregates and anonymizes billions of transactions, saving them in time series distributed database. It helps the end users by giving a single overview of how the entities are performing, giving early warnings if the behavior is not as expected. The software is used in the compliance and regulatory space.

Mortgage Approval Platform with Blockchain

Worked on the first blockchain initiative in the banking sector in the Netherlands. The project aimed at providing a transparent mortgage approval process using Hyperledger fabric. I was responsible for developing a progressive single page web application using Angular 2+ and Loopback for the API. As well as responsible for data migration from the old legacy system to the replacement product.

Automated Web Scraping with Headless Browser

Responsible for creating web scraping solution using Puppeteer to scrape and aggregate public data on scheduled bases. The solution was containerized and deployed in the cloud writing the data into MongoDB for further post-processing.
