"Insight Asset Management for Jira" developer at Atlassian.
My journey with Atlassian started at a small, but quickly growing company called Riada Development AB. At the time, we were about 10 people in rather small office, but we were growing at an exponential rate. As our company grew the number of developers quickly doubled, we got new offices, new structures, and a lot of big exciting projects. Insight is the parent to all of those projects, and is a testament to the excellence of the company and all of my fellow colleges. Insight is an asset management engine tightly coupled with Jira that gives you complete control over all of your companies assets and processes. Everything from complex relationships, automations, flows, graphs to even include automatic company asset discoveries with the help of external tools. During my time here I've worked with a myriad of different technologies and environments. From "old-style" large monoliths built in Java utilizing Atlassian SDK:s with Spring, Active Objects and an aging but solid Soy/Jquery front-end (ES5 era, Internet Explorer 8). To new style microservice "cloud first" architectures relying on many small de-couped components with microservices talking over GRPC. Our hosting relied on Docker/Kubernetes and amazon AWS. And our front-end contained the latest that the Javascript/Typescript world had to offer in terms of features and frameworks. Mindville AB is as of summer 2020 a part of Atlassian, with swedish offices closing in January 2022.

Shopello is an online shopping API used by a number of sites and partners to drive shopping traffic to different web-stores based on a cost-per-click model. During my time at Shopello we've made many of the systems several times faster and partook in several large, if not complete re-writes. We also added new functionality that enabled us to manage much larger volumes of traffic, which in turn have allowed us to establish ourselves in new countries. My duties also included improving our feed management for our customers, keeping things running smoothly and making sure our traffic doesn't include bots. The role has been a large growing point for me and I've learned many new development concepts and technologies. During my time at the company we unfortunately got into SEO and partner issues, and after a company merger and several cuts, me and several of my colleges had to leave.

Android developer for a project known as "Exqube", an IOT solution for measuring and storing various data about connected devices. The application consists of a background-service that communicates via bluetooth in order to measure values from our connected box that can replicate things like car dashboards.

JOTI (Jamboree on the Internet) is a scout event that occurs every october. During 48 hours, our event at Mälarscouterna holds a number of competitions and tournaments in an number of games and activities while we at the same time help them connect to other scouts The event usually held about 60 computers connected to enterprise switches and a self built linux box managing all the internet traffic.
