You want to build a web application…

…but you fear you might have to hire a whole team.

You know hiring is hard. Hiring technical talent is even harder.

What if you could work with one trusted, passionate developer to prototype your application from idea to product?

Teejay VanSlyke

Hello! I'm Teejay. I've been developing web applications professionally for over a decade. In that time, I've built everything from social networks to ecommerce apps to highly integrated enterprise apps and everything in between.

Whether you're a startup founder with an idea and a dream or a project manager at a large company, I'm eager to help with your next custom application.

My clients are often pleasantly surprised by my ability to craft every aspect of their application, from the user interface all the way down to the server configuration. I pride myself on being a generalist:

u·ni·corn — /ˈyo͞onəˌkôrn/ — noun

  1. a mythical animal typically represented as a horse with a single straight horn projecting from its forehead.
  2. a company valued at over one billion dollars.
  3. a developer who can design, build, maintain, and deploy your web application all by themselves.

Here's who I've helped recently:


Chatlio provides live chat with website visitors directly from within Slack. They got in touch with me when they realized their user experience was lagging behind their competitors. I did a survey of their competition, made user interface recommendations, and worked closely with them to deliver a new, sparkling interface for their chat widget. And they've received great feedback from their customers.

PS Dept.

For three years, I was PS Dept.'s sole API developer, helping turn their early invite-only beta iOS product into a full-fledged e-commerce experience. Since we launched and become wildly successful in the Manhattan styling industry, I've helped maintain the Rails-based API and built tools to assist our styling team in operating more efficiently.

What my clients say about me:

Teejay can solve any problem with code. He is personable, smart and fast. Over the course of seven years I have watched him build half a dozen startups by himself.

Beyond being a great developer with a great personality, he truly wants to build the best product possible and is always pushing the envelope for design and experience. Making products that are beautiful, elegant and functional is what he does best.

There is nothing that would stop me from working with Teejay again. In fact, working with him has ruined me for working with other less capable developers.

He’s an amazing talent and a force to be reckoned with.

Teejay did an amazing job of exceeding our expectations.

I was able to engage with him immediately. And he made a a big impact, fast.

We improved our product experience quickly without many changes to our backend code.

It was well worth the investment we made and we received great feedback from our paying customers on the improvements.

We will definitely hire him again when the need arises!
