Ruby on Rails Developer

Hi!
I'm looking for a full-stack Ruby developer with at least 3 years of experience.
I need help for my startup which is saas and an e-commerce platform, which creates online stores.

Required skills are Ruby, PostgreSQL, Bootstrap, Amazon API

The first tasks (among many) include:
- Improving Multi-tenant architecture
- Roles
- Apply the new Bootstrap style
- Amazon S3 integration

Looking to hire asap as my current developer has a full-time job with another project.

Thanks.
