20–35 days to MVP. E2E, crypto wallet like Coin Chat — scope at brief.
Why custom messenger
Telegram/WhatsApp — foreign rules and data. Your messenger — closed community, B2B comms, or vertical chat with monetization.
Niche UX
Coin Chat: chat + wallet for collectors. Your fields, moderation, CRM.
Real-time
WebSocket, offline sync, typing, read receipts. Load tested.
Mobile + web
One backend; FCM/APNs push; deep links.
Monetization
Subs, PRO, paid groups — your model.

Technical aspects
Reliability, security, and scale built in from day one.
Performance
DB indexes, cache, and queues keep the system fast as data and users grow. Load testing on staging before production.
Security
HTTPS, role-based access, audit logs, and API key protection. Personal data handled per your compliance model.
API & webhooks
REST and webhooks for website, 1C, Telegram, and partners — no manual re-entry. API docs included.
Mobile web
Responsive layout and PWA — most users work from phones. Native iOS/Android apps when needed.
Backups
Automated DB and file backups with verified restore on staging. Data loss in normal ops is unacceptable.
Staging
Test environment for team training and integration checks before release. Updates roll out without blocking core ops.
How we build it
-
01
Brief & scope
Scenarios, roles, integrations — MVP and estimate in 1–2 calls. We lock v1 priorities and what moves to phase two.
-
02
Prototype
Wireframes for key screens and admin — revisions before build. UX flows agreed so logic isn't rebuilt mid-project.
-
03
MVP
Working flow on your domain: core modules and test data. Your team walks through scenarios on staging before live integrations.
-
04
Integrations
Payments, 1C, Telegram, partner APIs — verified on staging. Test payments, doc exchange, and webhooks before go-live.
-
05
Launch
Deploy, team onboarding, monitoring first operations. Handover of access, docs, and support for first iterations.
