Experience
Ibank/mBank
http://ibank.ge/Developed an API for internet and mobile bank applications. This application is used by several thousand people daily. It has many modules that include paying communal or other bills online, transferring money, creating deposits or taking loans, the ability to convert money in different currencies, checking your pension funds, a personal financial helper, and almost all services related to the banking ecosystem.
Core Banking System
Developed a Java-based core banking system API that replaced the legacy banking app currently used by the bank's employees to server external users. It made it easier to serve users much faster and complete their requirements.
Bank Loyalty Program
Created a Java-based API for a bank's loyalty program. The bank's users are able to earn bonus points when they are using their bank cards. This application gives them the ability to manage their bonus points and spend them with different things or services. It is also possible to pay communal bills with bonus points.
Full-text Search
I was a solo developer on this project. This project’s main purpose was to accelerate searching in documents and to make searches easier and with more search options. Because there were many documents, search was getting slower, so I used better technologies like Elasticsearch. After this project, users were able to make full-text search more quickly and easily.
Digital Signature
I was a solo developer in this project. It was created for users who wanted to sign documents digitally with their ID card. Our software was connecting to a national agency of public registry and checking if the ID was valid, and then was asking for a pin code before creating a PDF document with valid digital signature.
Aces of World War II
https://www.youtube.com/watch?v=4I9I1flHihAA 3D video game about World War II plane fights. It had a single-player mission mode and also multiplayer. Players could use different planes with different stats and skins. I created the gameplay and the enemy AI.
