Founding/Staff Engineer with strong product sense and bias toward action. Former founding engineer at Monograph (Series B SaaS) where I wrote 80% of code through $160K ARR and helped scale from 1 to 25 engineers.
What I bring: Technical leadership on high-risk architecture decisions, experience mentoring engineers, and a track record of building scalable systems from scratch. Strong product sense focused on asking the right questions and figuring out what not to build. Comfortable diving into new tech stacks and problem domains.
Looking for: Teams where I can blend hands-on IC work with collaboration and teaching. Especially interested in ML/LLM applications. Want to work on something that makes a real difference—whether that's boring business software or cutting-edge tools.
Recent projects: Esports analytics with Elo ratings, spaced repetition learning tools in Go, and an experimental musical keyboard
Looking forward to hearing about what you’re building!
