Hello

I'm Andrew Crookston

Product engineer, developer and designer craftsman.

I’m passionate about building great products and companies, combining experience across engineering, design, and management to build and grow great products.

About

Developer

As a full stack developer, I work on everything from: backends, APIs and websites with high amounts of traffic, to designing and building user interfaces. I’ve built business applications, information retrieval, and search systems, as well as several consumer and social media apps.

With over fifteen years in the software industry, I've worked with many programming languages and frameworks like: Swift, Ruby, Objective-C, Java, and many more.

Designer

Growing up in Scandinavia, the son of a designer, I’ve been exposed to beautiful and functional craftsmanship throughout my life that has translated into the work I do today.

Good design is key to the success of any application, and at the core of all work that I do. I primarily design and develop user experiences and interfaces but I occasionally draw illustrations, logos, etc.
