Production Architecture Migration & Security Hardening
Complete migration to unified Go binary architecture with enterprise-grade security, improved performance, and comprehensive workflow automation.
Unified Go Architecture
Successfully migrated from distributed Cloudflare Workers to a unified Go binary, delivering significant performance improvements and operational simplicity.
- Single binary deployment eliminating cold starts and reducing latency to <100ms
- Integrated HTTP and WebSocket servers for real-time communication
- Hand-written SQL queries with SQLite for optimal performance
- 100% API compatibility maintained during migration
Enterprise Security Implementation
Comprehensive security audit and hardening across all deployment pipelines, infrastructure, and application layers.
- Eliminated all critical security vulnerabilities (code injection, unsafe downloads, secret exposure)
- Implemented principle of least privilege across GitHub Actions workflows
- Added comprehensive security scanning, monitoring, and alerting
- Secure systemd configuration with NoNewPrivileges, PrivateTmp, and memory protection
Advanced Workflow Engine
Production-ready workflow system with intelligent retry logic, real-time monitoring, and automatic recovery capabilities.
- 12-step cluster provisioning workflow with atomic operations
- Exponential backoff and retry mechanisms for network resilience
- Real-time progress tracking via WebSocket with status broadcasting
- Automatic workflow recovery system for stuck processes
Deployment Infrastructure
Fully automated, secure deployment pipeline with comprehensive monitoring and verification systems.
- Security-hardened GitHub Actions with timeout controls and input validation
- Automated health checks and deployment verification
- Service user isolation and comprehensive file permissions
- Real-time deployment status monitoring with rollback capabilities
