LeanIX

Senior Software Engineer • March 2021 — Present • Ljubljana, Slovenia

In March 2021, Cleanshelf was acquired by LeanIX, and the product was renamed to LeanIX SMP (SaaS Management Platform). I stayed in the same team and my role did not change much since then while LeanIX is continuing the "empowered engineers" culture. Since the acquisition, we have been dealing with product maturity while also focusing on the new functionalities and connecting with LeanIX's main product (EAM), where I am mostly responsible for the development of private API. Soon after the acquisition. we also completely migrated from Angular.js to Vue.js, and from Google Cloud to Azure Cloud.

Cleanshelf

Senior Backend Engineer • Jan 2021 — March 2021 • Ljubljana, Slovenia

After 2y working as a platform engineer, I decided to go back to development while having a close connection to the product. In Cleanshelf, engineers were empowered to lead the projects, talk to customers, and be involved in planning. I have been working mostly with Go and MySQL, while also touching Angular.js, Vue.js, and Python quite often. We were used to continuous deployments while running altogether on Google Cloud.

GoAvio

Full Stack Developer • Jul 2016 — Oct 2018 • Ljubljana, Slovenia

GoAvio was meant to combine millions of low-cost flights, buses, and trains to find cheaper and faster routes. I took care of data integration (API/scraping), API development, features for B2B customers, and back office maintenance (CS functionalities, data analysis, and KPI views). The technologies involved were PHP (Laravel, Lumen), Angular2 (for back-office applications), Postgres (the database was our UI), Redis, AWS, Docker, Vagrant, Grafana, InfluxDB, etc. In the latest stage, a part of the team was starting to build various microservices with Go lang, so I also got involved in Go learning.

I worked on 15+ projects, from large-scale to small-scale. Most of the applications were built with Symfony2 (PHP framework), but I also started to learn Ruby and Ruby on Rails here. We used open source libraries and I had the chance to contribute to some of those. Since we had dedicated front-end developers, I was also introduced to the modern (well, at least at that time) front-end technologies such as Grunt, SASS, Compass, Bower etc. As developers, we were closely involved in the development process (workflows, planning etc.) and I also had a chance to organize internal monthly tech talks.

I also wrote and used Python parsers to collect data from various websites, and I worked on a few other experiments during the internal Hackdays.

Agile Team and Project Management

Good knowledge of agile project development processes like Scrum or Kanban. From my experience, there is no perfect predefined process that fits every organization, but this is something that should be incrementally developed and improved – just like software. I have some experience with implementing workflows and functionalities in Jira, but I do not mind using any other project management tool, as long as it covers all the needs. I also have experience with leading sprints, and organizing meetings and events such as tech talks and hack days. Also, I got really confident using Confluence or similar tools for documentation, meeting minutes, async discussions, etc.
