## Services

Start with a free 30-minute intro call, or send a written brief (https://antonshubin.com/book#brief): I write back with 3 concrete architectural improvements, free, within one working day.

- [Strategy session](https://antonshubin.com/catalog/strategy-call) — $150, 60 minutes. A 60-minute working call about your project or idea, with notes afterwards.
- [Code & security audit](https://antonshubin.com/catalog/codebase-health-audit) — From $1,500, 3 days. I check your app's code and security and tell you what to fix first, including apps built with Lovable, Supabase, Cursor or Claude Code.
- [Build: MVP](https://antonshubin.com/catalog/zero-to-production-saas-mvp) — From $8,000, from 3 weeks. I build your product from idea to a live app on servers you own. Backends, AI features and MCP servers are built the same way.
- [Ongoing](https://antonshubin.com/catalog/cto-advisory-retainer) — $150/hour or from $3,000/month, ongoing. Ongoing technical leadership and post-launch support, hourly or on a monthly retainer.

Fixed price when the scope is fixed, hourly when the work is open-ended. A change to scope gets a quote before I start on it.

## Promises

- You own everything from day one — code, accounts, servers and keys are in your name.
- Five-day refund — if in the first five days you feel this is not working, tell me and I refund what you paid.
- A small first milestone — we start with one or two weeks of work. If either of us wants to stop at the end of it, we stop — you keep everything built so far.
- Weekly working software — you see working software every week, with a short written update. Calls when they help, not on a schedule for its own sake.
- Free bug fixes for 30 days — bugs in what I delivered are fixed free for 30 days.
