I am backend developer with devops experience. Working professionally since April 2017.

I work mainly in Kotlin, I use vanilla* Javascript for lambdas (and for hobby projects) and Terraform for infrastructure management.

(*) because I don't wanna check everyday if someone put backdoor into my dependencies yet 😉

I have experience with distributed (often legacy) systems, various queues and database technologies.

My personal favorites are:

• RabbitMQ for events - it has simple UI, it is easy to setup and to write integration tests for and it works for many scenarios.
• DynamoDB/MongoDB as NoSQL database - when database is just a persistence layer for basic CRUD - therefore SQL strictness, transactions and/or JOINs are unnecessary.
• Docker for containerization - de facto standard, but it is cool anyway.
• ECS for container orchestration, it does the job without complicated setup.
• EC2 for managing computing fleet
• Lambdas and Javascript (spread operator is a killer) for gluing and reshaping data with fast feedback loop.
• API gateway for exposing public services and common authorization layer.

Notable mentions for my tech stack include Application/Network Load Balancers, Route53, security groups, IAM roles and basic Linux and networking skills.

Not actual technologies but stuff I find useful for debugging:

• EXPLAIN (and cousins) to debug why freaking query is sloooow
• bash (and xargs) for quick scripts to be thrown away later on
• grep for fast scanning repositories, because if "it" is there grep will reveal it
• netcat (and curl) to debug if (where) I hit firewall
• nestat and ip to debug my VPN connection issues

My usual tasks revolves around doing stuff that requires more expertise and deep dive into docs. I also like to improve things and to simplify day-to-day project life in general.
