Hi, I'm DJ!

I thrive in the gap between people and
the value they seek from software.

I'm an Arkansas-based Full Stack Software Engineer. I like to walk my dog Monkey, explore the hidden gems of Northwest Arkansas, and write the DJ Codes newsletter on Substack.


About me

I'm a full stack developer who excels at solving problems with code. I have multiple eight-figure exits and tons of learning experiences along the way. I love to work and expect to never stop hacking code.

Bachelor of Science, Music Education

Northwestern University1986-1990

I decided by my senior year that I didn't want to teach, but NU is expensive so I took the degree and became one of those classic liberal arts major who had no idea what he wanted to do. Luckily I discovered I have an entrepreneurial instinct and a knack for computers.

Submarine Sales Methodology

Innovative sales method that trained me to, above all, not act like a salesman. See this post on my blog about one key concept, the Up Front Contract.

DJ is a great asset to any software development team. He's a bonafide team player, and commits himself 110%. My team and I were lucky to have someone of his caliber on board at Content BLVD. And I'd be honored to work with DJ in the future.

During my time working closely with DJ at BlueSpruce, I had the opportunity to witness his exceptional leadership and organizational skills firsthand. His ability to effectively lead and inspire a team was truly commendable. DJ consistently demonstrated a strong vision for the company and effectively communicated it to the entire team, fostering a sense of purpose and motivation among employees.
