Highlights: 10+ years of experience as freelancer in FinTech,Healtcare and HR applications Proficient in Ruby on Rails on the backend, and lots of other tech on the frontend. Specialized in optimizing, legacy code, database performance. Experience as DevOps well. Full background: As a nineties kid, I was already tinkering/dabbling around making games and invoicing software on our first pc at home. In university, while doing my engineering and mathematics degrees, I was scripting and using a lot of different technologies on complex physics problems. In 2012, I discovered Ruby/Ruby on Rails and a lot of things just clicked/felt right. I've specifically looked for RoR startups, joined an early stage FinTech startup that exploded and has had a successful exit. From then on, I turned it into my career and never looked back. I worked in FinTech, Healthcare, HR applications, picking up different domains and iterating upon complex calculations on the way. I've architected several green field/new applications from the ground up, all of them are still in use today. Amongst them are some high traffic enrollment systems in sports and leisure. I've worked with all Rails versions, even facilitating a migration from a huge (400 models plus) legacy rails 2 application to modern standards. Along the way, I've seen some very interesting PostgresQL optimization problems. You can't go so long and not pick up some DevOps as a side quest, so worked with terraform, chef, Ansible, Kubernetes and all kinds of provisioning/hosting/deployment tools and pipelines. I've used most modern frontend frameworks (React/Redux, Vue, Angular, Ember) on different projects but for smaller applications I tend to prefer to keep it simple using Hotwire. Always open for a chat to see what I can do for you!
