PrayAI had 35,934 lines of infrastructure code supporting 12,900 lines of app code. We replaced it all with Rails 8, Turbo Native, and 184 lines of infrastructure. Here's the full story with real numbers.
Stanford studied 100,000 engineers and found AI boosts productivity 15-20%. But your stack, seniority, and prompting strategy determine whether AI makes you 30x faster or just generates bugs.
Your tech stack has a hidden cost. The Platform Velocity Index scores it across 7 dimensions so you can see exactly where the money goes. Here's how it works, with a real case study that went from 2.2 to 8.7.
Type /prototype in Claude Code and get a clickable HTML gallery of your app's screens—device frames, lightbox navigation, dark mode. Then fill in each screen by sharing screenshots. Here's the command and the workflow.
Subscriptions via RevenueCat, rewarded ads via AdMob—two bridge components, one ERB partial, zero JavaScript API calls. Built for Fitivity, works anywhere.
We manage 800+ mobile apps. Claude Code's agents and slash commands let us define implementation standards once and enforce them everywhere.
Most managers spend 90% of their time managing. The ratio should be flipped. Here's why leadership matters more than management — and what the difference actually looks like.
I've seen too many great products get built for problems that didn't exist. Here's the systematic validation framework I use to test ideas in 4 weeks—combining AI-powered outreach with real customer conversations.
I got my CTO Academy certification a couple years ago. Best investment I made in my career. Here's why every developer should consider it.
SF Ruby Conference 2025 videos are live. Start with Carmine Paolino's RubyLLM keynote—one API for every AI model, pure Ruby elegance.
Audio keeps playing when users navigate away in Hotwire Native. Three solutions: Stimulus disconnect, viewWillDisappear override, or native player. Here's when to use each.
Hotwire Native doesn't handle tab switching out of the box. Here's the path configuration pattern I use in PrayAI and Fitivity to make links switch tabs automatically.
You can build your product idea faster than ever. But user acquisition and product-market fit are still unsolved problems. Here's the one method that works—and how to implement it.
Build a ChatGPT-style streaming chat interface using RubyLLM and Turbo Streams. Real-time AI responses, automatic persistence, zero JavaScript API calls.
assert_turbo_stream, broadcast testing, WebSocket timing in system tests. The complete guide to testing Turbo applications in Rails.
turbo_frame_tag, turbo_stream_from, Broadcastable, and all the Rails helpers that make Turbo feel native. Stop writing raw HTML tags.
Upload a CSV, kick off a background job, watch the progress bar fill in real-time. No JavaScript polling. Just Turbo Streams and Action Cable.
Turbo's speed comes from avoiding work: snapshot cache for instant back buttons, prefetching on hover, morphing to preserve state. Here's how it works.
Nine actions, two delivery methods. Server sends HTML fragments, Turbo applies them. Chat, notifications, live dashboards—no client-side state management.
Wrap content in a turbo-frame tag and links inside it only update that region. Modals, tabs, pagination, inline editing—no JavaScript required.
Include one library and every link click becomes instant. Turbo Drive intercepts navigation, swaps content via AJAX, and makes your server-rendered app feel like a SPA.
Most web apps don't need React. Turbo gives you SPA-level speed with server-rendered simplicity—19KB instead of 200KB+ of JavaScript complexity.
The era of bloated startups is over. Ruby Growth Labs is my bet on Rails, AI, and tiny teams that ship fast and generate revenue faster.
Your SSP just pitched you on "curation." Here's what they're actually selling—and the 6 questions you need to ask before opting in.
The ad tech industry loves inventing new words for old concepts. "Curation" is sell-side targeting dressed up in new clothes. But the implications are huge—it represents a real shift in where targeting happens and who controls it.
Ruby 4.0 shipped on Christmas Day with ZJIT (a next-gen compiler from Shopify), Ruby Box for isolation, redesigned Ractors, and Set/Pathname as core classes. Here's what matters for production apps and whether you should upgrade.
Ruby just turned 30 and celebrated with Ruby 4.0 on Christmas Day. While the tech industry chases shiny frameworks, Ruby keeps quietly powering billion-dollar companies like Shopify, GitHub, and Airbnb. Here's why this "boring" choice is your smartest tech bet.
I've been running engineering teams across the US, Eastern Europe, and India for over 15 years. One of the most exciting things about this model is the potential for a near-24-hour innovation cycle - work genuinely moves around the clock. But recently, I've watched some of my teams burn the midnight oil a little too hard. Engineers staying up 24 hours because they felt they needed real-time collaboration. That's not the goal. That's a failure mode.
Look, I get it. Every industry is asking this question right now. "Will AI replace [insert profession here]?" But after watching developers panic about AI coding tools only to realize they make us more productive rather than obsolete, I see the same pattern playing out in real estate.
I just published a detailed piece over at Ruby Growth Labs about why business leaders should choose Ruby on Rails, and it got me thinking about my own journey with the framework.
In many of today's apps, we have TOO MANY LAYERS of abstraction!
I've spent years building AI products for different industries. Real estate? It's sitting on a goldmine of opportunity. Most agents are either completely ignoring AI or using it like a fancy calculator. That's a mistake.
Implementing Proper 4xx Response Codes for Mobile Apps
A Model Context Protocol (MCP) server for interacting with the App Store Optimization tasks. This server provides tools for managing locales, translations, meta data, keyword ranking data and screenshots.
JavaScript went full circle in 10 years—right back to server-side rendering.
You’re already familiar with APIs—the building blocks that let software talk to other software. Whether it’s fetching weather data or connecting a frontend to a backend, APIs have quietly powered the digital world for years. Now, there’s a new concept worth knowing: MCP — Model, Context, Protocol.

Stop overengineering MVPs. Launch faster using Rails, AmericanCloud, Cloudflare, and Kamal. Simplify, ship, and scale later. Fractional CTO tips.
Scaling engineering teams demands people skills. I compare the curriculum from the Strengths Deployment Inventory (SDI) with Primal Questions to help you understand which one is right for your team. As a Fractional CTO, I use these to scale teams and drive growth.
As an early-stage founder, you’re brimming with ideas and eager to bring your vision to life through a web or mobile app. Prototyping is your first step toward validating your concept, but it’s easy to fall into traps that waste time, money, and momentum.
My wife has an impressive list of marathon and Ironman finishes. She's strong, fast, and loves pushing herself. For the past few years, she had issues with her hips. Finally, late last year, she sought help from a physical therapist and was then referred to get an MRI. We discovered...
Let me show you how to save money by deploying Docker containers to non-big-tech cloud providers using Kamal-Deploy.
Over the past month, we have cleaned up our AWS account to reduce costs significantly. Initially, we were spending $135 per day, and in this article, I'll show you how I lowered it to $47 per day.
After two decades of asking myself the question what should I use to build my personal blog? I finally have found a solution and I’m happy with and I think I’ll live with for a long time.
After graduating from the Art Institute of California, I was developing many marketing sites and working for a digital marketing firm. There, we used ASP.NET and a CMS named Ektron. It was during this time that DHH released the infamous “Oops” video where he generated a blog and released the first version of Rails. The simplicity caught my attention, and the elegance of Ruby deepened my curiosity.
