Revise & iterate until you're 100% happy

A great user experience is usually an iterative process. We'll keep revising your project until you're 100% happy with it.

How I can help

There are a few different ways I can help you ship faster, reduce costly mistakes, and simplify your development process.

  • Analysis & Audit. I can help you identify expensive bottlenecks, hidden issues, and potential problems with your site. I’ll put together a detailed report with actionable next-steps on how to fix any issues.
  • Roadmap & Planning. We’ll identify your goals and challenges, and I’ll put together a custom roadmap to help you get there.
  • Implementation. I can build your project for you, or work with your engineering team to accelerate your progress.
  • Team Training. Give your team the skills they need to get more done. Grow, retain, and attract talented developers.
  • Ongoing Advisory. Throughout the duration of your project, I’ll be available to review progress, answer questions, recommend tools and processes, share emerging best practices, and keep your project on the right track.

I knew you were good, but I was a bit skeptical of the value versus the investment. But not now. There are several other things that have impressed me beyond your skill set.

  • You're very efficient with your time.
  • You can take the ball and work independently without needing a lot of my time. When you do need my attention, you are well prepared.
  • You’re not a cowboy in terms of imposing your own coding style on the project. You respect what is in place and fit in with that when possible.
  • You like dogs.
- Randy Craven, Stella Tainer

I leave your code better than I found it

I’ve been building for the web for a long time, and worked with a wide range of users and clients. Technology is only as interesting as its ability to solve problems.

If your code is missing a README and documentation to get developers up to speed quickly, I’ll write it. If there are accessibility or performance issues that make it harder (or impossible) for people to use your site, I’ll flag them and fix them.

🎯 My goal isn’t to close tickets, it’s to help you be more successful.

Frequently Asked Questions

How many hours do I get each month?

I don’t bill by the hour, and I don’t track hours. I’ve found it to be a very inefficient and unpredictable way of working with clients.

You might find some freelancer on Upwork for $35/hour and think “I could hire them at the same price and get 200 hours of work!” But that’s like comparing apples to oranges.

My focus is on delivering results at a consistently high level of quality and as little risk to you as possible. Without that high bar of quality, more hours of work just means more code to fix in the future.

I know hourly billing is entrenched in this industry, and this may require a mental leap you’re not yet comfortable with. That’s why I offer the money-back guarantee. Try it out and see for yourself.

How many tasks will you complete in a month?

I ship one or two meaningful deliverables each week, on average.

Because tasks can be of wildly different complexities, bigger tasks might get broken up into smaller parts. For example, “Improve validation on our checkout page” is much different than “Build an integration with this third-party API.”

Along the way, you will get a steady stream of updates and progress. No more dealing with developers that “go dark” for weeks or months at a time.

I want to make sure you are getting consistent value out of our relationship.

Can you join our daily standups or a weekly 1-on-1 call?

No. I keep meetings to an absolute minimum. It’s one of the big reasons why I’m as efficient as I am. But don’t worry, you’ll know exactly what I’m working on at any given time.

I’ve streamlined my process and made it completely transparent, so routine communication and check-ins are unnecessary. It’s better this way!

How do I request tasks?
If you already have a project management system we use, you can give me access to that and start assigning tickets to me right away. If not, I’ll set you up with Trello, a card-based project management tool.
How do I explain a complex task or project?

I love context and knowing more about what you’d like me to build.

Record a short video clip using any tool you like, and link it in the issue or ticket. If something is still unclear, we can set up a brief chat as needed. In my experience, though, that’s usually unnecessary.

Is there a limit to how many requests I can have?

Nope! Once you’re subscribed, you can add as many tasks to your queue as you’d like, and they’ll be delivered one-by-one.

You can move requests around and set your own project priority to ensure your most important tasks are finished first.

What if I don’t like how something turned out?

No worries!

Development is an iterative process. Unlike an agency that will charge you extra for change orders, you get unlimited revisions until you’re happy with the work.

Why wouldn’t I just hire a full-time developer?

The cost of a hiring full-time senior JavaScript developer averages over $150k/year, plus benefits. And if you don’t have enough to keep them constantly busy, you’re stuck paying for time you aren’t able to utilize.

With Fractional JavaScript Development, you pay less than half that. And unlike a full-time employee, you can easily pause my services at any time, and restart them when you need more work.

If you don’t have enough work to hire someone full-time, Fractional JavaScript Development can give you access to expert-level JavaScript expertise and keep your business moving forward.

Who are the developers?
Just me, Chris Ferdinandi. Unlike big agencies, I won’t farm your work off to junior developers or outsource things. You get to work directly with me, a senior developer with over a decade of experience.
