🚀 Production & Engineering Proof

  • Agentic AI & Commerce Gateways: Built agno-commerce-agent, an autonomous AI bookstore assistant with Python FastAPI, dynamic function tool-calling, simulated QRIS generation, and resilient multi-provider key rotation with sub-second SSE streaming.
  • Infrastructure: Migrated full application stacks between VPS providers (Vultr to Contabo) and reconfigured core services.
  • Storage & Cloud: Moved multi-cloud object storage across Vultr, AWS S3, and DigitalOcean Spaces using rclone with zero data loss. View notes
  • Agent Concurrency & Gateways: Built autonomous WhatsApp bridges with file-based mutex concurrency locks and automated FFmpeg media transcoding for AI agents.
  • AI Infrastructure & RAG: Deployed Qdrant Vector Database (qdrant.brofesional.id) with local Ollama embeddings for semantic knowledgebase retrieval.
  • Database & Backups: Automated containerized MySQL backups to Google Drive with log rotation and Telegram alert reporting. View project
  • Messaging: Set up FCM push notifications, transactional email infrastructure (Brevo, Mailketing), and automated DNS routing.
  • Delivery: Configured GitHub Actions CI/CD pipelines for automated testing, container builds, and deployment.

🧪 Selected Projects & Labs

  • Agno Commerce Agent: Production Agentic AI commerce gateway with FastAPI, dynamic tool calling, QRIS generator, multi-provider key failover, and SSE live stream.
  • Hermes Local Agent Lab: Multi-provider LLM routing, Telegram/WhatsApp agent gateways, MCP Trello, and approval-based coding automation.
  • Antigravity Session Manager: CLI session engine, SQLite database manager, and DX architecture RFC for Google Antigravity.
  • Laravel Backend Portfolio: OpsLedger API demo with JWT auth, RBAC, queues, sandbox payment webhooks, Docker Compose, and CI.
  • Laravel VPS Hardening Lab: Production-minded server hardening patterns for Laravel applications on Ubuntu (Nginx, PHP-FPM, SSL, Fail2Ban).
  • rclone S3 Operations Playbook: Practical workflows for copying, syncing, dry runs, ACLs, bucket policies, and safe IAM access revocation.
  • MySQL Docker Backup: Automated MySQL backups from Docker to Google Drive with rotation and Telegram reporting.
