Work on integrations: Bitrix24 REST API, webhooks, external services. For Junior Developer: Deliver small tasks: component, template and form modifications; field and permission configuration. Fix defects based on QA reports. Write simple event handlers, agents and REST calls following existing examples. Build and refine interfaces (HTML/CSS/JS). Document own tasks; take part in code review as an observer. For QA Engineer: Build the QA process from scratch: test plan, checklists, acceptance criteria, pre-release regression. Functional, regression and integration testing of product modules on Bitrix24. Testing of REST APIs (Postman / Insomnia), webhooks and integrations with external systems. Automation of priority regression scenarios (UI and API). Logging and tracking defects, reproduction, prioritisation together with the lead.
