December 2025 in ncc-erp/ncc-erp-workflow-w2 delivered two strategic features and strengthened security for external API integration. Key outcomes include the Day Off Reason List to streamline leave management and security hardening for Mezon API integration through environment variable updates and addition of secrets in configuration/deployment workflows. No major bugs reported this month. Overall impact: faster, more reliable leave processing; reduced token management risk; more robust deployment configurations. Technologies/skills demonstrated include backend feature development, API integration security, environment/configuration management, and CI/CD workflow improvements.

Consolidated 2025-08 work for mezonai/mmn: Delivered a comprehensive Node CLI overhaul with a dedicated node/bootnode flow, YAML-based genesis configuration, and multi-backend storage (LevelDB and RocksDB); added Genesis provisioning with multi-account initialization and faucet support, plus README guidance for multi-node deployments. Standardized and hardened transaction handling by removing TxTypeFaucet in favor of TxTypeTransfer and strengthening gRPC/ledger validation, with Jest-based test coverage for transfers. Introduced a Redis-backed debug block store, wired into the factory for faster debugging. Completed build, Docker, and documentation cleanup to improve caching, deployment examples, and remove dead code. Overall, enabled faster, scalable node deployment, stronger transaction integrity, and cleaner CI/CD workflows.

June 2025: Delivered Mezon-based identity and API exposure across AMS and related frontends, enhanced authentication reliability, and established systematic HRM data synchronization. Implemented frontend integration for mezon_id, improved token-based user_id extraction, and added robust name normalization with Vietnamese diacritics support. Introduced background jobs and logging to bolster reliability and troubleshooting. These changes improve user provisioning speed, security, and data consistency across AMS, AMS-FE, and workflow services.

May 2025: Completed the foundational Blockchain Core Platform with P2P networking, dynamic port allocation, secure signing, and enhanced Fund Transfer/BalBalance APIs. The work establishes a decentralized app foundation with robust cryptography, testability, and scalable networking, delivering measurable business value through secure transactions, reliable peer communication, and improved API capabilities.
