Experience

Knowledge Management System

I used a Moodle-based platform integration to create an internal (intranet) knowledge management system in a financial institution. I extended the existing solution by adding custom features to fulfill user requirements in a few cases. We ended up with a plan with wiki pages, virtual conference rooms for training, etc.

Laboratory System

A desktop application where laboratory employees can store information about samples and laboratory tests. It was a part of a more extensive system used by customers, doctors, etc., to order tests, show results, create reports for the company board.

FliteDeck Pro

A mobile application used by pilots in their daily work. Users can see the current route with airplane position and see helpful information about air zones. In general application can work offline but there's a sync-in process implemented when crew is on land and have access to the internet.

Airline Documents Web System

A web-based app where airline employees can store documents, for example, about some issues like engine failures, repairs made, etc. Everything is stored in PDF documents. Users can download, upload, read and edit stored documents.

Light Maintenance System (LMS)

A web-based system that helps maintain lights in the buildings. Using Internet of Thing technology (Raspberry PI), users can see all issues on a graphical floor plan in real-time. After doing necessary repairs, there is a possibility to test a specific lamp if everything goes back to normal.

Mortgage Advisor

An Angular project for Nordea Bank employees to help them with advising the best mortgage option for the customer. User can see different loan scenarios, edit input values and compare them each other. After doing simulation they can create loan promise and proceed with loan process.

Case Manager

A web-based system created to prevent money laundering. Using AI technology detects unusual transactions and highlights them to the operators who can block them, decide that it's nothing suspicious, or escalate further.
