Hi, I’m Jonathan Havens, a Las Vegas–based software engineer and team lead. I value clear communication, honest expectations, and steady delivery. Outside of code, I’m big on good ideas, good people, and making the most of the present.

Backstory

Ive been building reliable software systems for real users since 2016 — balancing architecture, hard deadlines, and feedback loops with great work without burnout.

My general approach to software is founded on a simple yet profound principle: no problem exists that hasn't been solved yet. This mindset, and 1st principles thinking, guide me on every project I've encountered. I prioritize understanding the core requirements and constraints before jumping to solutions. I often iterate on the problem statement itself, ensuring we're solving the right problem at the right time.
