Marija Spaic

Software Engineer

Marija is a software engineer coming from an original background in hardware and digital design. Having graduated with a degree in Electrical Engineering, she decided to pivot to software, attracted to the possibility of coding in languages more nuanced than assembly. To this end, she first gained experience in the .NET world, building applications to run industrial fabrication machines. At Spantree she enjoys working across the stack, from Python and Groovy to Javascript and React Native. In her free time, you may find her at the nearest climbing gym or planning her next outdoorsy adventure.

Jonathan Freeman

Senior Software Engineer

Jonathan, who has been interested in computer programming since playing Myst and Lode Runner on his grandmother's computer, comes to software development though music. After a few years studying jazz saxophone, he decided to take his programming hobby more seriously and began consulting work. Through consulting, he's enjoyed working in various domains, from finance to healthcare to video games. While he specializes in JavaScript, both browser and server side, he also takes a keen interest in modern data stores (particularly graph databases). In his free time Jonathan tries to cook tasty treats and build things out of wood.

Kevin Greene

Senior Software Engineer

Kevin is a Senior Software Engineer, and the primary math nerd. After brief stints in physics and academic math, he realized the creation of things was just as important as the theory, and became a full time programmer. Possessing a hodge podge of tools for any job, he particularly enjoys Clojure, Elixir, Kotlin, and pretty much every data store in existence.

If you ever want to math out, Kevin would love to talk about cryptography, algebra, graph theory, or number theory. In his spare time, his preferences and hobbies tend to change with the moon, but generally board games, RPGs, and some form of creation lie at the heart of them all.

He started his career working as one of the web hosting administrators in the eBusiness hosting team at IBM, soon he got tired of the red tape that big organizations suffer. After working for one year for a very large extended warranty company, he was asked to move to Chicago to work as the team leader for the web hosting administration team. During the six years working at The Warranty Group he met Cedric. Sebastian and Cedric became friends and begun introducing concepts that back then didn't have a name and today are known as DevOps practices.

In his free time, Sebastian enjoys trying new technologies, watching movies with his wife and playing Star Wars The Old Republic. Fun fact about Sebastian is he played rugby for 14 years.

Justin Nauman

Senior Systems Engineer

Justin has been a tinkerer interested in computers since the first time that he got his hands on one. After convincing his high school geometry teacher that programming a computer to do the homework for you shows a command of the subject, he decided to make a career of it! After going to school for Computer Science and Mathematics Justin started his professional career at AT&T doing internal consulting with a variety of technologies in the telecom space. Always curious about how things work and trying to press the envelope, Justin has continued to broaden his technical skill set over the past 10 years.

At Slalom, Justin spent the last several years bringing solid engineering principles into the full software delivery lifecycle. Justin has been particularly excited helping clients adjust their development methodologies and technology stack to best leverage that AWS platform. Justin has a passion for finding the right tool for the job and is currently in love with all things Hashicorp and Kubernetes.

If you can’t find Justin at one of the many Meetups in Chicago he attends, you can probably find him playing with his daughter, spending time with friends and family or out on a boat.

Andy Hamilton

Senior Systems Engineer

Andy's memories of using the computer date back to futzing with the Commodore 64 and watching his father play games on the family's Amiga, but it wasn't until late in high school that he started exploring the web and became an intentional user of free and open source software. In college at the University of Wisconsin some of his time was lost trying out lesser known linux distributions - remember Corel Linux? - but the bulk went toward earning his Bachelor's degree in Computer Science.

After a brief stint developing with proprietary technologies, Andy has spent almost the last 15 years around or near Java, doing everything from web apps to batch jobs to swing apps. More recently, Scala and Haskell are fighting for his attention. He is currently avoiding the temptation to write yet another monad tutorial.

Outside of work Andy helps to organize the Chicago Area Scala Enthusiasts (CASE) Meetup group and frequently attends several other meetups. To relax, Andy likes to spend time with his wife playing co-op video games or traipsing around a new Chicago neighborhood.
