Hello.
I'm Colin, a full stack Ruby and Rails for more than 5 years. I believe I can help to develop your system continued from an open source ror project.
About backend, I've worked on big data, data & architecture design, cache, cron job, redis, batches, etc.
About front end, I can create website UI using html, css, bootstrap, jquery. I can use some js frameworks like ReactJs, VueJs
Hope to have your response.
Regards.
Colin
