I'm technical and obsessed with turning painful problems into shipped, monetized software.

I've built products for venture-backed startups, raised angel capital for my own products, and operate a product engineering business I scaled to $330K+ ARR.

I'm especially interested in founders who deeply understand an industry/problem and need a technical counterpart who can move extremely fast.

I build hands-on myself, and I have a small engineering team I can bring in when speed matters. I'm also open to investing personally when I have high conviction.

Achievements:

• Lead a team that has built products for 4 venture-backed startups, including 2 YC-backed companies
• Scaled builtbyharness.com to $330k+ ARR
• Raised a $50K angel check from a former google exec for one of my own products
• Closed $13k + $7.2k ARR deal with a CDFI to automate their loan underwriting
• Grew @junhong.liao from 0 → 20,000 Instagram followers in less than 60 days
• 30B+ tokens burned in claude code

How I work:

• Pick a painful problem
• Test demand
• Ship in 10 days
• Kill, Refine, or Double down
