We know, many Rails experts are undervalued. Paid like it's the 90s. They deserve more than they value themselves. While businesses can't find real talent. One platform. Rails-only. Personally vetted. No BS. This is why we built Rails Expert 👇 https://t.co/teJwAm6kUR

Do y'all know @chatwootapp? Just onboarded them as a client and if you're a rubyist you should pay attention. Chatwoot makes an open source customer support tool in Rails and it's open source! I know several developers from their team and I can assure you - it's a great team.
