Jonas Hässel is a Senior Software Engineering Contractor at Hässel Kod & Form Aktiebolag. They is proficient in English and Swedish. Colleagues describe them as "I've had the pleasure of meeting Jonas when he was contracting for Divido and I was a full time worker. Although we were not working in the same project for long, every interaction we had left me amazed of his analytical capacity, his practical (no bs) approach to engineering and his technical expertise. We viewed many things the in similar ways and it was a shame we could not work longer in the same project. He was always available when I had questions about how certain things in our platform worked an he was always ready to show me the ropes anytime I needed it. An excellent individual with an outstanding sense of humor. I'll certainly miss our interactions." and "It's rare to come across a standout talent like Jonas. During my time at Divido, Jonas was the Guru whenever it came to any technical tasks. Highly skilled at PHP, Go, AWS infrastructure and many more, I don't remember a problem that Jonas could not solve. Great mentor and model for any developers, Jonas is as good as any Software engineer can get. "

Senior Software Engineer Team LeadDivido Dec 2015 - Mar 2020London, United KingdomFollowing a short stint as contractor for them, I joined Divido full time as the first tech hire and worked directly with the CTO for four years. During that time we went from our first integration with a small e-commerce site to working with the biggest international banks.The company grew from 9 to +70 with around half working in tech during my time and the biggest team I managed was 6 persons, but due to the startup nature that size fluctuated wildly.I was part of the core tech team responsible for architecture, strategy and contact with high profile accounts, but I also wrote a whole lot of Go, PHP, JS, handled a bunch of data in various databases, pipes and search indices and wrangled AWS.Due to the nature of the service provided, we handled a lot of personal data and a lot of money flowed through our systems and that gave me pretty solid experience in navigating the regulations around data retention and financial services.By far my most interesting 4 years and I learned a lot from some very smart people.

Node.Js & React ContractorAcast Sep 2015 - Oct 2015Gothenburg, Vastra Gotaland County, SwedenDuring a short but intense period I worked alongside the Lead at Acast, building their new web. It was before React had reached 1.0 and it required a bit of creativity and perserverance to keep up with the sudden changes in the API. A great oppurtunity to dive head first into something new and start delivering value right away. -
Senior Systems DeveloperStim Aug 2011 - Aug 2015I was the first hire with a focus on web and Linux and was the principal developer for their new business system, replacing and augmenting existing systems.My team grew from me to four more during my years and was my first formal foray into tech leadership, but it had no people management component. The development was based on an open source CRM project and made together with a consultant agency with which I had the main technical contact.The project went on for several years, spanning diverse parts of the business and that meant a lot of requirement management, integration with everything from IBM big iron to modern JSON services.This happened during a technical shift in the company, from legacy mainframe tech to a more modern stack and many very useful lessons were learned. -
