    Hello and thank you for reading my profile! My name is Henry and I am at your service. I have been working with Ruby on Rails for four years now. I still love coding with Rails every day. I consider myself a polymath of many computer techonologies, with a strong focus on Web Development, and a strong focus on Rails within Web Development. I choose to focus on Rails because I find that its developers make careful and considerate choices about low level code implementations so that as an application developer I can focus on delivering high level features. Whether you need your current app debugged or you have an idea that you want to design and deploy, I will give you my honest opinion on what your app needs and how long it's likely to take. I have a lot of web development skills: 1. Modeling and implementing your business logic with ActiveRecord and MySQL or Postgres. 2. Deploying to Heroku, using Heroku plugins for SQL, SendGrid, asynchronous tasks and scheduled tasks. 3. Configuring DNS. 4. HTTP protocol examination and debugging including Cross-Origin Resource Sharing and many other headers. 5. Frontend Coding, I especially like StimulusJS, Turbo, and Hotwire as well. 6. Keeping users engaged with push notification technology. 7. Familiarity with Docker. 8. Familiarity with Ansible. 9. Familiarity with Ubuntu Server. I'm looking forwards to joining your project and making a strong contribution. Thank you very much.

And to jumpstart the process, *the first 10 hours will be at 60% discount for the next 2 clients.* Are you working with an existing web application, or have a new idea for one? I specialize in web applications that are powerful and simple to use, specializing in React, Next.js/Node.js, and Python platforms. That includes: - SaaS apps - AI and LLM apps - Crypto and Web3 apps - Mobile-ready apps When it comes to your investment in a web app, there’s factors that only experience can bring to the table. ▶ You'd like to build an MVP or prototype, but don’t have programming experience. ▶ You’ve got a skill that could be automated and marketed to hungry clients, but coding and software isn’t your specialty. I’ve experienced the launch of multiple products, and can share that experience so that you and your product don't have to get stuck in the pitfalls. What I do, in a nutshell: ▶ Build new product ideas starting with wireframes and UI/UX, so if you’re starting from scratch and don’t have everything fleshed out, there’s a process in place to take that idea all the way to a profitable launch. ▶ Take your existing web app and build new features so your business can benefit from new revenue sources, without the money lost from the time it takes to rewrite from scratch.

    With nearly two decades of experience in design and technology, I bring a unique blend of UX and frontend expertise to my role as a product design leader in Colorado. Over the past 19 years, I’ve had the pleasure of working with both startups and established brands like Droplr, Peterson’s, ETHDenver, Inspirato, American Express, Colorado.com, the city of San Francisco, and Squaremouth. My approach is deeply rooted in creating accessible, effective UI designs that balance aesthetics with functionality, enhancing user experience through thoughtful, detail-oriented design. My technical expertise spans a broad spectrum, from frameworks like Vue and React to the latest in HTML, CSS, and JavaScript. I am also skilled in using Astro, Tailwind, and Bootstrap to bring designs to life with clean, scalable code. As a performance optimization enthusiast, I prioritize site speed, Lighthouse scores, and SEO, knowing that these metrics not only improve user experience but also boost conversion rates and drive revenue growth. To this end, I leverage my skills in tools like GA4, PostHog, and Amplitude, collecting and analyzing data to inform data-driven improvements that maximize impact. I am an advocate for Agile methodologies and hold a Scrum Master certification, enabling me to efficiently lead teams and projects with iterative improvement and user-centric focus. My hands-on approach spans from design ideation to development execution, using a blend of Figma, Sketch, Adobe CS, and UXPin to visualize and prototype ideas, and tools like WordPress, Netlify, Git/GitLab, and AWS to bring them into production. In my past projects, I have led the migration of complex tech stacks (like transitioning Peterson’s from a .NET framework to Laravel and Vue) and collaborated on high-impact digital partnerships, such as 'Inspirato with American Express', which increased membership sign-ups by 40% within its first quarter. My design philosophy is inspired by minimalism, professionalism, and the powerful role of details. One of my favorite quotes is by Charles Eames: “The details are not the details—they make the design.” Whether in typography, color, or alignment, I believe in the impact of refined details, clean code, and thoughtful design choices that together create an engaging and intuitive user experience. In addition to UX and frontend work, I consult on site reviews and heuristic evaluations, uncovering ways to increase revenue by boosting conversion rates and enhancing user journeys. Driven by a passion for learning and staying on top of the latest tools and trends, I’m always eager to explore new methodologies, experiment with emerging JavaScript libraries, and continue growing my T-shaped skill set. Whether you’re looking to elevate site performance, optimize user flows, or build a standout digital experience, I’m here to help bring your product vision to life.
