Web Developer in San Francisco

San Francisco is the most technically demanding market on this list and the one where I am most often working alongside an existing engineering team rather than replacing one. The usual arrangement is capacity: a startup with two or three engineers who need a marketing site, an admin panel, an integration or a customer portal built properly without pulling anyone off the core product. That means working inside their conventions — their repository, their branching strategy, their review process — rather than delivering something in isolation and handing it over.

The other recurring brief is the pre-Series-A build: a founder with a validated idea who needs a real product rather than a prototype, and who will be showing the codebase to a technical diligence process within a year. That changes what matters. Tests on the paths that carry money, a data model that will not need rewriting at ten times the volume, documented deployment, and no clever architecture that requires its author present to explain it. I build assuming a stranger will read it, because in that scenario one will.
