Full Stack Developer with Ruby

With 7 years of experience in small startups to large companies I've worked across the stack doing front-end, backend and infra / dev tooling. I'm interested in setting up early stage products with a deep integration to the business side, or do well scoped feature or maintenance work on mature projects to bring them to the next level. Bonus points for Climate Tech, Geographical Information Systems, FinTech or infra/ dev tooling, but I'm open for any interesting challenges specially as part of a small team.
