A senior engineer as your part-time technical lead: architecture decisions, code review, hiring help, vendor and agency checks, and hands-on building when it's faster, through a monthly retainer you can pause or cancel.
What you get
- Architecture and stack decisions, written down.
- Code review and engineering process for your team.
- Help hiring and interviewing engineers.
- Hands-on building on the parts that matter most.
Good fit if
- You're a non-technical founder with a product to build.
- You have developers but nobody senior reviewing them.
- You need technical answers for investors.
