About Me
20+ years in IT, 10+ years focused on SRE and DevOps — designing, implementing, and automating CI/CD pipelines for cloud-based and on-premise enterprise applications. Track record of modernizing legacy systems, optimizing infrastructure, and improving software delivery efficiency across FinTech, telecommunications, and other mission-critical environments.
Currently pursuing an EMBA in AI & Digital Transformation, bridging deep technical execution with executive business strategy.
Core Focus & Modern Practice
☁️ Cloud-Native & Infrastructure as Code
- AWS production architecture: EKS, VPC networking, IAM boundaries, ALB/NLB
- Terraform and OpenTofu module design for repeatable, reviewable provisioning
- Containerization, image optimization, and private registry hardening
- Immutable infrastructure and air-gapped deployment packaging
🔄 CI/CD & Delivery Automation
- Pipeline design for both cloud-based and on-premise enterprise applications
- Legacy system modernization and incremental migration strategy
- Progressive delivery: canary releases, gradual rollout, zero-downtime deploys
- Build and release efficiency measurement, toil reduction programs
☸️ Kubernetes & Platform Operations
- Production EKS operations: workload isolation, capacity planning, HPA tuning
- Nginx Ingress Controller for TLS termination, routing, and long-lived connections
- Multi-tenant governance and platform-as-product golden paths
- GPU workload scheduling for local inference workflows
🚪 API Gateway & Traffic Engineering
- Kong Enterprise and Tyk architecture design, migration, and evaluation
- TPS benchmarking, rate limiting, and upstream failure isolation
- OpenAPI contract enforcement and service-to-service authentication
- WebSocket and long-connection routing for mobile and web clients
🤖 Hands-on LLMOps
- Enterprise LLM platform integration for production AI applications
- Prompt engineering and cross-model evaluation methodology
- Model output stability: regression detection and guardrail design
- Agent loop failure modes and token budget as a FinOps guardrail
🎯 Solution Delivery & Pre-Sales
- Technical pre-sales engagements for major financial institutions
- Enterprise PoC scoping, delivery, and acceptance criteria definition
- Architecture reviews, trade-off documentation, and decision records
- Cost and ROI framing for infrastructure and reliability investment
Selected Experience & Impact
Financial Infrastructure Modernization & Pre-Sales Delivery
FinTech & Regulated SystemsLed technical pre-sales engagements and enterprise PoC delivery for major financial institutions, including tier-1 commercial banking environments. Work covered API gateway migration, transaction-per-second capability evaluation against production traffic profiles, and isolated air-gapped deployment packages built to satisfy regulatory compliance, low-latency requirements, and high-availability standards.
Real-Time Communications Platform on AWS EKS
Platform & ReliabilityDesign and operation of the platform layer for a chat application serving Android, iOS, and web clients. Scope spans cluster architecture on EKS, ingress and long-lived WebSocket connection handling through Nginx Ingress Controller, release strategy for a multi-client surface where mobile app versions cannot be forced forward, and the Prometheus/Grafana observability stack that backs on-call.
Technical Writing & Knowledge Dissemination
Author & CommunityWriting at dockerdevops.blogspot.com since 2018, a Traditional Chinese technical blog for IT managers, architects, and senior engineers in Taiwan. The focus is production-proven engineering practice rather than neutral surveys — container optimization, cloud automation, SRE governance, and more recently AI agent architecture and cost control.
Also an active contributor on Stack Overflow, with open-source and configuration work published on GitHub.
