Started working in a startup with the same team. Got more responsibilities and a fast-paced environment. Honed my skills both in software development and data engineering. Architected, improved, and maintained various data systems and pipelines. Deployed various applications on AWS and Snowflake. Had a chance to adapt to very restrictive environments and work with previously untouched tools like Ruby on Rails and Java.

Software Engineer at Freelance

Dec 2020 -> Jun 2021

During the pandemic I had a bit more time which I decided to use to diversify my skills and get better at software development. I've worked on various projects from triangular arbitrage calculations for cryptocurrencies to web scraping and data processing. Vast majority of my work was done in Go or Python. This is where I've learned communicating with customers and building software that is easy to use and understand.

Digital Marketing Specialist at Hostinger

Oct 2019 -> May 2021

As strange as it sounds looking at the job title - this is the point in my career where software development started to become something more than a hobby. While I've worked on various issues related to digital marketing, due to the format of our team I was a "go to" person for all the things related to tech. These included writting blog posts about various technologies, creating custom tools for our team, or even websites depending on marketing needs. This is where I had a chance to learn about web development and use tools like Go and Python.
