Oct 1, 2025October 2025 performance summary: Delivered a broad set of end-to-end CPS, billing, and sales improvements that enhance revenue recognition, payment processing efficiency, and customer-facing reporting, while stabilizing the codebase and security controls. Highlights include end-to-end CPS enhancements with summaries, PDFs, and advance payments; money handling and complete customer payment processing across backend and frontend; finalized sales invoicing/purchase workflow with vendor search; code scaffolding and cleanup with removal of extraneous comments and pagination; and critical bug fixes (auth middleware correction and merge issue resolution) that strengthen access control and integration stability. These changes establish a solid foundation for CPS integration with the bill controller and improved financial reporting.

Sep 1, 2025September 2025 performance summary for SlnkoEnergy/bacKendSlnko focused on stabilizing the foundation, expanding PO/payments capabilities, and improving deployment parity and reporting. Key work included implementing core Redis integration (client setup and URL wiring) and deploying Redis via YAML with health checks for dev/prod, complemented by development YAML and Docker Compose updates to streamline local environments. A caching layer was introduced to boost read performance, and substantial PO/payments enhancements were delivered, including new API endpoints, summaries, PO status completion, and PO number support for approval PDFs. Data accuracy and reporting were improved through fixes to balance display (TotalAmountPaid visibility), PO amount_paid handling, and customer payment parsing. Reliability improvements included reverting a problematic Redis change to restore stability and updating MoveToTrash scheduling. Additional code quality work and infrastructure improvements supported maintainability and future velocity.

Aug 1, 2025August 2025 highlights for bacKendSlnko (SlnkoEnergy): completed a backend modernization focused on real-time communications, payments, data models, and stability. WebSocket integration was cleaned up by removing legacy socket.io references and aligning index usage to improve real-time updates and reduce debt. End-to-end payment capabilities were enhanced, including PayRequest functionality, payment approval workflow, and SCM integration, with full traceability via new cr_id in PayRequestModels and related controller improvements. Data modelling and reporting were strengthened through PO model corrections, PO CSV handling improvements, PO-number-based retrieval, and KW-to-MW corrections in Project Balance, plus Material model addition. The backend foundation was solidified with staging scaffolding, cron task enhancements, and broader infrastructure stabilization, while accounts/approvals were augmented with backend changes and UTR progress tracking. These changes boost reliability, visibility, and business velocity in payments, approvals, and reporting.
