## Services

# I build emails and websites that just work.

I turn designs into responsive email templates and custom HubSpot websites. You get clean, modular code your team can edit without breaking anything. I work with agencies and in-house teams, and I manage each project myself from kickoff to handoff.

12+ Years building emails and websites

50+ Agencies and brands worked with

30+ HubSpot sites and migrations launched

500+ Email templates built

## How it works

1. 01
   
   ### Discovery
   
   We go over your designs, platform and deadline. You get a clear scope and timeline before any work starts.
2. 02
   
   ### Build
   
   I code the templates, modules or pages and share progress links along the way so you can give feedback early.
3. 03
   
   ### Test
   
   Everything is tested across email clients, browsers and devices, and any issues are fixed before you see the final version.
4. 04
   
   ### Launch and handoff
   
   I upload and go live, then walk your team through editing so you're never stuck waiting on a developer.
