Work Experience
May 2023 - April 2024
Software Engineer (.NET) at TripHub
Developing mobile application with web service related to automating the creation of
transit map using mixed-integer programming (MIP) approach. Performed tasks on both
client and server-side.
Also, my experience includes:

● Improving calculation time and optimization of complicated transit networks by adding
and fixing linear constraints for existing mathematical model.

● Implementing a simplified mathematical model in MIP representation to address the
challenge of automated labeling for transit maps.

● Conducting the design and development of the database functionality.

● Developing a REST API providing secure access to optimization and graphical
libraries hosted in the cloud.

● Deploying API on Azure using containerization tools, establishing a testing
environment.

● Implementing authentication and authorization mechanisms to ensure secure access
to API resources via Azure provider.

● Integrating a module for exporting geodata about public transport from Overpass
turbo to General Transit Feed Specification (GTFS) format.

● Developing algorithms for processing raw GTFS data into the required format for
further optimization and transit map creation.

● Creating visual components in the resulting transit map image, including text
rendering and line designs for routes.

Technologies: MS Visual Studio 2022, .NET 7, .NET MAUI, ASP.NET Core Web API,
OR-Tools, Moq, EF Core, SQLite, XUnit, SkiaSharp, Docker, Microsoft Azure.
