Experience

Trading Model with Reinforcement Learning

While working with a crypto startup as a research hobby project, I analyzed the market and built a trading algorithm using reinforcement learning.

The RL model is remarkable for its ability to adjust changes automatically.

Secure Land Titles on the Bitcoin Blockchain

In 2016 the National Agency of Public Registry of Georgia became the first governmental organization in the world to integrate blockchain technology in the mainline business process to secure land titles on Bitcoin blockchain.

As a technology solution architect, I was responsible for planning the solution, leading the development, and integrating it with the existing production systems.
