Hey, I'm
Dayton Johnson.
Full stack builder
Senior engineer at HubSpot in Commerce, responsible for frontend architecture around pricing, line items, and products. I'm also building Posing Perfect and Career Iterator.
About
I build product-facing SaaS and the systems that help teams move faster without adding complexity.
At HubSpot Commerce, I help cross-functional teams simplify pricing, catalog, and line item workflows so the product can grow with fewer hidden edge cases. I enjoy writing RFCs and leaving behind systems that are easier to maintain.
Outside work, I ship two products: Posing Perfect, a coach-and-athlete platform born from my own competition prep, and Career Iterator, a private corpus for tracking wins and mapping the next step.
- ▸Self-taught from the start
- ▸Competed in Men's Physique bodybuilding (Top 3 in debut)

- ▸Juggling and unicycling enthusiast (but not at the same time)
Experience
Senior Software Engineer @ HubSpot
Aug 2022 – Present
At HubSpot Commerce, I build frontend architecture for enterprise commerce workflows, including pricing, product records, and line item experiences.
Projects
Posing Perfect
A full-stack platform for bodybuilding coaches and athletes.
Built around a problem I ran into firsthand: preparing for my debut Men's Physique competition. I handle product, system architecture, backend (Supabase/PostgreSQL), frontend (Next.js/React), auth, testing (Cypress), and deployment (Vercel).
Career Iterator
An AI-powered career management tool.
Built independently as a tool for deliberate career growth: tracking what you've done, identifying where to go next, and making progress concrete.
