Ivan Edrennikov
Summary
Leading a small Balance team responsible for design and maintenance of Balance subsystem which is a part of payments processing system. Balance subsystem is for keeping and processing funds on users' accounts at Bolt.
At Bolt I had designed and built a Payment Allocation System which matches users' payments and orders to track which order is paid by which payment and which orders are not paid. This had resulted in a better visibility of fraud cases.
At Mail.ru I had designed and built a Promo Action system which gave easy way to setup promo campaigns.
My current technology stack is TypeScript and Node.js, but I also used PHP and Laravel, with all these backed up by MySQL as well as Git, Redis, AWS SNS, SQS and RabbitMQ.
I also have an extensive experience in the role of QA engineer. I have an experience with Selenium and WebDriver. I also have a good programming skills in Java as I used it to write automated tests.
