Production reference
ToyCRM.com is built and maintained by the same engineering team — the patterns in our consulting deliverables and courses come directly from that codebase. The receipts are public.

Five honest answers we give weekly to people about to write.
Will I really get a reply, or is this just a marketing form?
Real reply. Every message reaches a senior engineer on our team. There's no autoresponder beyond the form's submit confirmation. Median reply time: same business day. Slowest case so far: 26 hours, on a holiday.
How fast — and on weekends?
Within 24 business hours, Mon–Fri Tbilisi time (GMT+4). Weekend messages get a reply Monday morning. If something is genuinely urgent, mention it in the message and use the Telegram chat for parallel signal — that's seen faster.
Can I write in Russian / Ukrainian / Georgian and get the reply in that language?
Yes. Write in any of EN / RU / UA / KA — you'll get the reply in the same language. We don't make career-changers translate their own questions.
My project is small — do you still take inquiries?
Yes. A two-hour code review is treated with the same seriousness as a multi-month architecture engagement. The fit conversation is what matters — small projects with the right shape often turn into long collaborations.
Do you sign NDAs for B2B engagements?
Yes. There's an "NDA available on request" checkbox on the B2B form — tick it and we'll send a standard mutual NDA before any sensitive code or architecture is shared. Custom NDAs are also fine.
Maybe you don't need to write yet

Six weeks ago I installed @fission-ai/openspec. Yesterday I shipped a 14-file change in 90 minutes from a 200-line spec, in a brownfield codebase three engineers have been editing for two years — no merge conflicts, no review escalation. This is the senior-architect deep-dive on why OpenSpec is the first SDD tool that doesn't collapse under production reality.
