Experience

Travel Booking System

I worked alone on this travel booking software—building both the client-side and the back end. The back end was developed on ASP.NET Core 2.2 and used a RESTful API and Swagger. Every operation has unit tests.

I also integrated 21 service providers simultaneously while monitoring the system, sending requests to service providers, and processing responses without delay. All of the projects are deployed in Azure.

APP FEATURES:
• Two factory authentication and social authentication (based on the IdentityServer)
• Search for flight tickets, tour packages, and hotels
• Checkout system
• Payment methods: bank wire and credit card
• Discount feature
• Wishlist (add bookmarks for tour, ticket, hotel)
• Search history
• Azure blob storage
• Real-time price change (SignalR)
• Administrator panel

HR Management Software

On this project, I developed an HR management system using ASP.NET Core 2. The back end was developed on an ASP.NET Core RESTful API and used a microservice architecture.

FEATURES:
• Payroll is integrated with the financial software
• Create, read, update and delete (CRUD) employee data
• Record attendance and attendee reaction
• Working plan
• Two or three approval request levels
• Document flow
• Role and authentication by LDAP

Ticket Booking System

This project involved a ticket reservation system which was developed on ASP.NET MVC 5. The server-side was built with a RESTful API.
Tickets are sold from a web app, mobile app, and from the cash desk. All services are deployed on Azure.

Remote Identification/Authentication

https://application.rebank.ge/
I developed a remote identification/verification application for a new customer onboarding. I integrated Facetec product for liveness check and Microblink for OCR.
I also developed client/server-side functionality. I used React for the client-side and ASP.NET Core 3.1 RestAPI for the back end. Finally, I implemented CI/CD pipelines for this project.
This app made it possible to acquire new customers remotely, without getting them into the branch office.
