Description

Having a long background in software development and operations in web application systems, I specialized myself in Amazon Web Services technologies (experience of development and operating since 2014).

I am especially interested in Cloud systems with Amazon Web Service and Serverless architectures.

My favourite tools include: Serverless framework, AWS Lambda, Go, DynamoDB, Prometheus, Grafana
