Hi, I’m Hoàng Anh 👋

DevOps / SRE • Integration & Platform Engineer • DevSecOps (Cloud/Kubernetes)
I build reliable, secure, and observable platforms for banking & payment systems, with a strong focus on integration architecture, automation, and production excellence.

---

🚀 What I do

• Platform & Cloud Engineering: design and operate Kubernetes platforms (EKS/OpenShift), landing zones, networking, storage, and runtime hardening.
• DevSecOps & CI/CD: GitOps at scale (ArgoCD), pipelines (GitLab CI), quality gates (SonarQube), supply-chain security, policy-as-code.
• Integration Systems: ESB / API integration, event streaming (Kafka), messaging (MQ), workflow orchestration (Camunda/Zeebe) for mission-critical services.
• Observability: OpenTelemetry, log/metric pipelines (Fluent Bit), SLO/SLI, incident response and runbooks.

---

🧠 Specializations

• Banking & Payments: integration patterns, idempotency, reconciliation/traceability, resilient transaction flows.
• Kubernetes Production: reliability, autoscaling, rollout strategies, graceful shutdown, readiness/liveness, multi-tenant GitOps.
• Security by Design: secret management, least-privilege, threat modeling, secure SDLC automation.
• System Design: scalable, fault-tolerant architectures, event-driven patterns, API governance.

---

🧰 Tech Stack (most used)

• Cloud/Container: AWS • Kubernetes • Docker • OpenShift/EKS
• IaC/GitOps: Terraform • CloudFormation/CDK (Python) • ArgoCD • Kustomize • Helm
• CI/CD: GitLab CI • (plus experience with CodePipeline/others)
• Integration: IBM App Connect / API ecosystems • Apache Camel • Kafka • MQ
• Observability: OpenTelemetry • Fluent Bit • Prometheus/Grafana (where applicable)
• Languages: Java • Python

---

🏆 Highlights

• Led and delivered multiple cross-team initiatives for integration modernization and platform reliability in enterprise environments.
• Championed AI-assisted SDLC workflows: turning specs into consistent delivery artifacts (design → APIs → tests → runbooks).
• Strong experience with production change governance, risk/rollback planning, and operational readiness.

---

📌 Current focus

• Building secure-by-default GitOps templates (multi-tenant), reusable CI/CD blueprints, and standardized runbooks.
• Deepening expertise in payment architecture and enterprise integration patterns.

---

📜 Certifications

• AWS Certified Solutions Architect – Associate (SAA-C03)

🤝 Let’s collaborate

I’m open to collaborating on:

• Kubernetes / GitOps tooling and reference architectures
• DevSecOps automation (quality gates, security scanning, policy-as-code)
• Observability pipelines (logs/metrics/traces) and SRE practices
• Integration frameworks, messaging, workflow orchestration
