David’s like that friend who throws the coolest tech parties but somehow forgets to send out the invites — the Rails world’s best-kept secret, cruising the timeline with 7,489 tweets but still waiting on the crowd to notice the DJ spinning fire.

David’s biggest win is building a reputation as the go-to curator of Ruby on Rails talent, creating a weekly spotlight that brings attention and connection to both emerging and veteran developers, strengthening the entire Rails community fabric.

David's life purpose is to empower and elevate the Ruby on Rails ecosystem by bridging talented developers with opportunities and knowledge, fostering a thriving and well-informed community. He aims to be a trusted guide and resource, spotlighting innovation and practical wisdom in tech.

David values transparency, collaboration, and continuous learning, believing that code should be both elegant and effective without unnecessary complexity. He trusts the power of community in driving open-source innovation and believes in pragmatic approaches over perfectionism. He has a strong belief in sharing knowledge for collective growth and improvement.

David’s strongest asset is his ability to sift through vast amounts of tech information and spotlight what truly matters, serving as a compass for developers navigating the Rails landscape. His consistent engagement, expert insights, and knack for community-building are key strengths.

While David follows over 3,000 people and tweets frequently, his follower count is undefined, hinting that he might be undervalued or lacking targeted audience growth strategies. His broad approach might spread his influence thin, making it harder to build a deeply engaged core audience.

To grow his audience on X, David should leverage his curated lists by threading them into engaging tweetstorms, encouraging user participation through polls or retweets, and using hashtags strategically to increase reach beyond the Ruby community. Collaborations or AMAs with featured Rails devs could also amplify visibility and deepen connections.

Fun fact: David doesn’t just talk Ruby on Rails — he curates a weekly 'Rails devs you should follow' list, helping both seasoned pros and newcomers discover the brightest minds in the community.

This week's @Rails devs you should follow: A weekly curated list of folks, both well-known and unknown in the Ruby on Rails community, you should consider following. @onedevdeving aka Devin Starks, a Rails-loving software engineer, roams the globe with his family, building a marketplace for travelers while preaching the gospel of Hotwire over React’s soul-crushing complexity. Devin's been geeking out over Ruby on Rails tricks, hyping digital nomad visas, and building a slick travel guide tool. @_st0012 aka Stan Lo, a Taiwanese Ruby wizard at Shopify, crafts killer debugging tools like IRB and believes patience is key to driving epic open-source change. Stans’s been flexing their Ruby chops, from topping IRB contributions to boosting Sorbet with C++ flair and dreaming up a Ruby MCP server. @typecraft_dev is a 40-year-old Rails enthusiast and Neovim aficionado who believes shell scripts trump nixOS and vibes over perfectionism in coding. Typecraft_dev’s hyping a million-view video, teasing a big release delay, and geeking out over interactive Vim and cool art @jnunemaker is a seasoned Ruby/Rails maestro who’s been coding for 20 years, geeking out over shrinking databases by 35GB and merging monoliths, all while preaching the gospel of feature flags and chill software vibes. John’s been geeking out over shrinking databases, debugging Heroku woes, and raving about Screen Studio’s share links—all in a day’s code @djfpaagman aka Dennis Paagman, a decade-long Springest vet turned freelance Rails wizard, believes in turbocharging slow forms with Hotwire and proudly shipped his first contribution to Rails 7.1. Dennis has been geeking out over Turbo preloading tricks and Hotwire Native sharing, while riffing on Arctic Monkeypatches. @maciejmensfeld aka Maciej Mensfeld is a Ruby wizard who resurrected bricked Chromecasts, crafts Karafka to turbocharge Kafka on Rails, and believes open-source maintainers deserve more than GitHub stars to pay the rent. Maciej’s been hyping their Tides project, nerding out over RubyKaigi, and saving Chromecasts from Google’s outage chaos. @adrianthedev aka Adrian Marin, a Rails-savvy developer with a knack for hosting epic Ruby events, believes most apps are just CRUD waiting to be supercharged by tools like Avo, all while geeking out over Trix internals and dreaming of markdown magic. Adrian’s hyping up MicroConf, cheering Rails pals, and teasing Avo’s superhero powers at SF Ruby Meetup. @kennnG aka Ken Greeff is a seasoned coder and ex-CTO at Realbase, now crafting Clipflow, who swears coding sans AI is faster and believes custom demo videos are the secret sauce to winning clients. Ken has been spilling startup tea, from pitch decks to debugging woes, while building Clipflow into a creator’s dream tool, plus releasing YouTube tutorials for covering, amongst others, Rails.

Used to be on the fence re annotations in @rails apps. I now believe the added context is immediately available to us mere mortals, can benefit onboarding amongst others and, may improve assistive LLM coding. The annotaterb gem has you covered. github.com/drwl/annotaterb

I was so confused - Prism is just a tokenizer? What the… 🤦‍♂️ This right here is why LLMs won’t replace devs anytime soon. Context may be king, but nuance? That’s the crown. 👑 Thanks to @SourcegraphCody 's CodeSearch and the ability to chat with the source code as context this was clarified soon enough. Both time OpenAI models where used. The difference was valid context and knowing something was not right about the response in the table.

Hey @rails fam, my US freelance gig has ended so I'm now open to new ones or the right fulltime Ruby on Rails roles. I'm remote based out of Cape Town and can accommodate hours for overlap if required.

I was reminded earlier of the pains around configuration management and ENV vars even in @rails apps. More so on growing projects, where config has side effects on tests scenarios and so many other cases For an opinionated framework, Rails credentials does not seem to make the grade based on use and adoption. At least in my experience across a number of projects. With so many ways to config and load ENV vars in Rails there's a saving grace in @palkan_tula's anyway_config Gem. It's a seriously underrated way to maintain the sanity of a project's configuration. github.com/palkan/anyway_…
