What CRM development actually requires in 2026
2026 stack: Salesforce Apex + LWC + Flow, HubSpot custom apps via Operations Hub, Microsoft Dynamics 365 + Power Platform, NetSuite SuiteScript. Integration via Workato + MuleSoft. Custom: Postgres + Hasura/PostgREST + React for vertical CRMs. Salesforce, HubSpot, and Dynamics each require 6–18 months of platform-specific training to ship at senior level. "Generalist developer" skill rarely transfers — pick a platform deliberately rather than trying to span multiple. CRMs are deep wells, not breadth plays.
