Worked on two Oil and Gas related projects.1. Worked with legacy code written in Java in a team of 24 people (1 year 2 month)- Data mining- Batch processing large csv files- Microservice based architecture (RabbitMq)- Auditing data changes- Optimized large sql queries2. The second project was written from scratch in 6 month using Kotlin programming language.Implemented these parts of the project:- Security with Spring Session JDBC (User management)- Notification system using Web-sockets- Mailing service with Spring Mail + thymeleaf- Covered every part of the project with Unit tests and Integration Tests- Auditing changes from RDBS to NoSql- GCS (Google Cloud Storage) API3.

Including smart contract transfer transactions and also native transfers- All of the above functions are implemented for Binance Chain, Binance Smart Chain, Bitcoin, Ethereum blockchains- As a one the parts of the Open Platform projects Open API had an sdk integration, so i wrote ERC20 contract and deployed on test net- One of the task on this job was to download balance of token holders on ERC20 smart contract in a specific block number.To solve this task, i had to deploy archived node of Ethereum on a google server, and parse the transactions of the blockchain. Then to export csv file.As a result we created a PR to brew repository. Since the CLI tool had no enought stars, we could not merge.
