I have a high bias for action and like to move quickly and iterate. I'm a patient communicator and introvert. I'm a hacker at heart and like finding creative ways to push business to the next level.

I don't limit myself to "back-end" or any other parts of the stack.

But nowdays, I would like to focus mostly on coding things and product related work. I enjoy contributing to Open Source, it helps me grow as an engineer. You can find some projects that I built or contributed to in my github profile.

I have been developing for the web since 2007 and with Ruby on Rails since 2012. I am skilled in backend development as well as server-side rendered HTML. I have worked on a variety of projects from small scale to large legacy for a variety of different clients and employers. I have worked for startups, corporations and non-profits. I have experience working as part of team using agile methodologies, as well as working as a solo developer directly with clients. I am passionate about continuing my own education as a developer as well as helping others learn. I was the organizer of the Ruby meetup in Ann Arbor for over five years. I have also spoken at numerous conferences and user groups.

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!
