Custom CRM replacing boxed Bitrix24: deals, warehouses, delivery routes and BI analytics in one place.

Boxed Bitrix24 didn't fit the process: mixed batches of aggregates, multi-warehouse routes, manual margin recalc on every deal.
Designed a domain model for deals and warehouses, deployed via Docker, integrated with Bitrix24 for migration and dual-run. Margin and logistics calculators run server-side, not «Excel formulas».
All deals and deliveries flow through one system. The dispatcher no longer spends hours recalculating; the owner sees P&L in real time.
30 minutes — and you'll have a sense of scope, timeline and price.
