Julian joined me as a member of the CableReady and StimulusReflex core team in 2019. He helped pioneer some of the most compelling tooling to hit the Rails ecosystem since ActionCable was introduced. He has a gift for delving deep into highly technical problems and emerging with elegant solutions. He's a major influence pushing Reactive Rails to become a viable and exciting alternative to full stack front-end. I can't imagine anyone better suited to help you level up with Reactive Rails.

Julian is part of the Stimulus Reflex ecosystem bedrock, not only a foundational member but also quick to offer support and solution suggestions!

Obie Fernandez

I’ve been working on StimulusReflex with Julian since 2019. He is an integral part of the community and has done a lot to push it forward. One of the wisest developers I have ever met, I can always trust Julian to provide great explanations to hard and nuanced problems. I have learned a lot from Julian, and I’d encourage you to take advantage of the opportunity to learn from him as well.

Andrew Mason
Remote Ruby

You want to have Julian in your corner! He went to great lengths helping me with some thorny problems on more than one occasion. He brings his hard-earned experience to the table, which he gained working in the trenches for long years: no fluff, no BS, just solid, pragmatic advice. Ignore at your own peril!

Trinity Takei

Julian works hard to make the StimulusReflex community successful. He's very active in the SR Discord Community, helping newbies and experienced folks alike, and pushes the community forward. He has developed Futurism and a StimulusReflex profiler and is very generous with many other open-source contributions. If this course is half as helpful as he is, it will be well worth the money.

Ricky Chilcott
Mission Met

I turn to Julian regularly with questions about the kind of Rails and Stimulus problems that are new and unfamiliar territory for me. He's always got the answer, or some new idea that helps me get to the answer. It's always great having his knowledge and experience close by.

    StimulusReflex Core Team

    In late 2019, after having road tested several back- and frontend frameworks, I stumbled upon a relatively young project that promised to simplify Rails frontend development by reviving the HTML-over-the-wire approach using Websockets.

    Fast forward one year, and I’m on the StimulusReflex core team. Needless to say in these times, and probably a faint anecdote in a few years, the Corona pandemic had the paradoxical effect - by requiring social distancing in the immediate community - of bringing people on opposite ends of the world closer together.

    It so happened that while I was increasingly working alone and in need of a comprehensive and productive full stack solution, I started contributing to and polishing StimulusReflex and CableReady together with a bunch of fellow enthusiasts.
