• Full-time Japanese language study in Tokyo.

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 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.

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 Integration & Data Security

• Built an AWS Comprehend PII pipeline that reduced costs by ~99% while preserving detection quality.
• Created an AI Proxy Adapter with Amazon Bedrock integration and policy enforcement.
• Developed a Kafka → Neptune pipeline for MITRE-aligned knowledge graphs.
• Implemented fine-grained AI access controls with auditability and tenant isolation.

Technical Leadership

• Produced executive-level AI demos for the CEO's NVIDIA presentation.
• Led internal workshops on AI tooling and best practices.
• Recognized as Employee of the Quarter.
• Drove cross-functional enablement through reusable platform components.

DevOps & Infrastructure

• Optimized GitLab CI/CD pipelines, reducing deployment time by 40%.
• Deployed Kubernetes clusters using Helm.
• Implemented Terraform for infrastructure as code.
• Managed Kubernetes clusters using Kops.

System Architecture & Development

• Created Docker Compose development environment.
• Integrated multiple backend services and databases.
• Built low-latency streaming server using Golang.

Research & Implementation

• Evaluated WebRTC Mesh and SFU technologies.
• Integrated Pydantic for robust data validation.
• Refactored monolithic projects for better maintenance.
• Implemented CI/CD pipeline testing integration.

API Development & Optimization

• Optimized RESTful APIs using Golang PProf.
• Reduced API response times by 30%.
• Refactored codebases for improved modularity.

Research & Evaluation

• Implemented Apache Spark for data processing.
• Demonstrated GraphQL API capabilities.
• Evaluated emerging technologies for adoption.
