Experience

e-FON

http://profesor.fon.edu.mk
This is a fully-featured university information system. It is an electronic student service ERP for more than 4,000 students. Features include enrollments, reporting, teacher's intranet, student's extranet, dashboards, and examination procedures, to name a few.

Gatekeeper

This is a visitor management system for use in public US facilities. It is a kiosk application built for Windows that uses a touch screen. It issues automatic on-site badges with the person's photo, name, and reason for the visit. It also has a barcode reader and was developed for OneStop Security and Technologies in the USA.

HES Scaffold Calculator

This is a .NET-based solution that saves time and reduces mistakes. It is a product developed for Hoiberg Engineering Services. Users find it easy to generate scaffold constructions where the program handles the calculations. If the scaffold is overloaded, it is possible to change the parameters and ensure it is mounted to handle the load it is exposed to.
The system also generates a list of loads in each spire. The load is the weight of the scaffold, as well as the load class for which the scaffold must be certified. Furthermore, a list of equipment needed both by specialists and included in the total.

The system also produces:
• The number of square meters of the scaffold.
• The number of cubic meters of scaffold.
• The total weight of the scaffold.
• Weight per vertical (pressure on the ground in suspension).

It is also possible to export the drawing to DFX and create an item list and calculations in Excel and PDF formats.

Sports Surebet API

A collection of odds (including live) from 80 different sports betting sites and APIs. Crawlers were developed in C# and Python. Some of them used Selenium WebDriver in both languages. Live odds change every 10 seconds; therefore, some websites, such as Bet365, require the orchestration of multiple threads on multiple machines with different IP addresses to provide valid data. The data was then pipelined in a central database and aggregated to provide live sure bets generated using 270 different cross-market combinations. The results were published as a live feed via an API developed in WebAPI 2 and secured with JWT.
