Orchestration
Companion-Orchestrator Agent Center
Designed and shipped an agent-orchestration platform on Google ADK with clear app architecture and module boundaries.
Implemented Agent-to-Agent (A2A) communication to coordinate remote agents.
Built an LLM agent with tool use, state tracking, retries, and error handling.
Delivered a web Playground for scenario testing and prompt/tool debugging; frontend developed independently with AI-assisted workflows.
Created a CopilotKit adapter and composed multi-step LangGraph flows.
Enabled dynamic agent loading via database-backed configs for zero-downtime rollout.
Authored ADK ↔ AGUI Middleware (Python 3.13+) providing SSE streaming and Human-in-the-Loop workflows; integrated with the orchestrator.
Achieved an end-to-end pipeline A2A → ADK → LangGraph → CopilotKit adopted cross-org with other teams.
→ ADK-AGUI Middleware (GitHub)
Platform
Platform Development & API Management
Built a plugin-based API platform that lets teams ship integrations without core changes; provided lifecycle hooks, auth, and rate limiting.
Developed a Collector Manager for configurable log routing with backpressure and retry controls.
Created a Mini-Companion system with GitHub-based sync for declarative workflows.
Implemented a Companion Proxy enforcing PII redaction and policy-based request filtering.
Infrastructure
Cloud Infrastructure Optimization
Re-architected EKS node groups: moved monitoring to ARM nodes for cost savings and introduced dedicated CPU-/memory-optimized pools.
Resolved Kubernetes compatibility defects in Stream Lake environments.
Authored modular Helm charts to standardize deployments across services.
Fixed CNI IP exhaustion and routing issues to stabilize multi-tenant clusters.
AI & Security
AI Integration & Data Security
Built an AWS Comprehend PII pipeline that reduced costs by ~99% while preserving detection quality.
