About this Gig
Stuck on how to build, fix or scale your app? Send me your idea, spec or repo, and I'll answer in writing with a clear plan you can act on, or hand to any developer.
You get:
- Answers to your questions, specific to your project
- Recommended stack and architecture (mobile, web, backend, payments, AI)
- Risks, rough effort and a build order
- For code reviews: the main problems ranked, with exact fixes
I build and run Workspace369, a SaaS with a web app and mobile apps, so the advice comes from shipping, not theory.
Written answers mean nothing gets lost, and you can reread them anytime. If you want a call, add it as an extra.
