      Web Development Review from James Leonard Ehrlich, DVM

      I wanted to outsource front end development while maintaining back end services myself.They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used.The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have.Their professionalism and competency were impressive.I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.

      May Halpirn's Review Sourced from Google

      Curious about another reviewer who looked older, a job applicant, who didn't have his call returned. Frogslayer slung cliche pablum his way. Apparently they hire Jr. Devs but do they hire over a certain age? Do they know the law? Their Senior Dev is under 30 and was hired from being a student employee. Curious and curiouser. Maybe Frogslayer isn't as woke as they appear. Friend of mine went through the ringer with them was told they'd get feedback either way. Instead they got the standard blow off rejection after devoting way too much time on a company that might not value "employees over a certain age." Heads up Frogslayer. There are laws.

      one of the only companies in town actively seeking real beginners/students to become junior level developers using all stacks and not focused on a particular one but most importantly not stuck with legacy tech debt.
