================================================================================
PROFESSIONAL SUMMARY
================================================================================
Experience:
6+ years building production-grade infrastructure, backend systems, and LLM
applications. Specialized in Kubernetes orchestration (Talos Linux, ArgoCD),
Infrastructure-as-Code (Terraform), distributed systems design, AWS scale
operations, and GPU-accelerated inference.
Core Competencies:
Production Kubernetes (Talos, GitOps/ArgoCD, 99.2% uptime). Terraform IaC
with drift detection. AWS distributed systems (57+ regions). Golang backend
services. Observability (Prometheus/Grafana/Loki/Tempo). Message queuing
(Kafka/Temporal workflows). GPU inference (vLLM, 60% latency improvement).
Zero-trust networking (OIDC/RBAC).
Strengths:
Owning systems end-to-end—design doc through oncall. Building fault-tolerant
platforms with 99.2% automation. Unblocking teams with clear technical
communication.

SELF-HOSTED PRODUCTION (riotpiao.com)
DevOps / SRE / SDE
Home Lab | May 2025 — Present
Challenge & Solution:
Built AWS from scratch at home on bare-metal Kubernetes—Talos Linux for
secure immutable OS, ArgoCD for GitOps pipeline automation, SOPS for
encrypted secrets management, cert-manager for PKI. Result:
production-grade multi-tenant platform with Kafka, PostgreSQL, S3, GPU LLM
inference, Temporal workflows in 4-node cluster.
Tech:
• Kubernetes (Talos, ArgoCD) — Talos immutable, atomic updates, no SSH, full
GitOps state. ArgoCD automatic sync with drift detection. Cilium eBPF CNI.
• Terraform + Kustomize — Declarative infrastructure. State management via
Terraform Cloud. Kustomize overlays for multi-env.
• Secrets & Security — SOPS age encryption with git audit trail. Authentik
OIDC SSO with Kubernetes RBAC. cert-manager + Let's Encrypt (30d renewal,
7d pre-expiry alerts).
Infrastructure & Services:
• Longhorn 3-replica block storage. MinIO S3-compatible API. CloudNativePG
PostgreSQL with pgvector for embeddings. vLLM GPU inference (Qwen3-32B,
60% latency vs baseline).
• Observability stack: Prometheus metrics, Grafana dashboards, Loki logs,
Tempo traces, OpenTelemetry. 99.2% uptime via monitoring automation.
• Kafka/Redpanda streaming. Temporal workflows for fault-tolerant jobs.
Forgejo CI/CD with Docker registry. DinD runners for parallel builds.

ROYAL BANK OF CANADA (RBC)
Lead Software Engineer
Toronto, ON | Nov 2024 — May 2026
Challenge & Solution:
Deployments were manual and slow—teams blocked 2+ hours per release waiting
for provisioning. Standardized on Terraform Cloud for idempotent IaC. Built
Temporal workflows for multi-cloud orchestration with built-in retry logic
and idempotency keys. Reduced deploy time from 2 hours to 20 minutes,
achieved 99.2% automation.
Drift Detection & Reconciliation:
• Built Kubernetes CronJob (Golang) to continuously detect and reconcile
Terraform state drift against actual infrastructure. Automatically
detects divergence (network policies, security groups, storage) and
triggers remediation without manual intervention.
• Coordinated across 4 platform teams, unified 200+ microservices into
single IaC standard. Cut onboarding time for 12 teams.
Notifications & SLA:
• Designed Slack notification service with Golang workers. Alerts on apply
failures, drift detection, provisioning bottlenecks. Operators resolve
issues in <5 minutes via notification-driven workflow.
Stakeholder Alignment:
• Led requirement gathering across 4 platform teams. Translated technical
decisions for non-technical stakeholders. Secured buy-in for platform
migration. Unblocked 3 stalled projects by disambiguating specs.
Tech:
• Golang, Kubernetes, Terraform Cloud, IaC, Distributed Systems
• Slack API, multi-cloud orchestration, state drift reconciliation
• Notification-driven operators, 99.2% automation

AMAZON WEB SERVICES (AWS)
Senior Software Engineer (Step Functions)
Seattle, WA | 2022 — 2024
Challenge & Solution:
Owned Distributed-Map from design doc to production launch across 57+
regions. Under tight deadline, introduced separate state in Map vs new
functions—simplified customer adoption. Built checkpoint recovery for
mid-workflow failures so customers resume without full re-run.
Distributed Systems Engineering:
• Solved critical edge cases: race conditions in concurrent state updates,
dependent service failures, message deduplication, exactly-once semantics
across distributed workers.
• Introduced JSON state input for larger payloads—unlocked new customer use
cases (batch processing, ML model serving, data pipelines).
Production Ownership & Reliability:
• Full oncall ownership—built CloudWatch dashboards, wrote operational
runbooks, debugged production issues live. Achieved sub-100ms P99 latency
across 57+ regions and 20x burst traffic scaling.
• Disaster recovery procedures and incident response. State management for
failed/retried jobs.
Tech:
• Java, AWS Step Functions, DynamoDB state storage, gRPC, Distributed Systems
• CloudWatch observability, ownership, disaster recovery, exactly-once delivery
• 57+ regions, sub-100ms P99, 20x burst traffic

NETFLIX TITUS (Container Orchestration)
Software Engineer Intern
Los Gatos, CA | May — Aug 2019
Challenge & Solution:
Streamlined Personal Data Detection (PDD) to identify classified data
exfiltration anomalies—achieved 97.8% accuracy with minimal false positives.
Built fault-tolerant Golang connector for PDD integration with 28% p99
latency improvement over legacy implementation.
Compilation & Integration:
• Re-integrated SmartRegex with CMake & C++ on Linux/Unix platforms.
Achieved 5x faster deployment through automated build pipeline and
dependency resolution.
• Prevented classified data leakage across Netflix's distributed workload
platform.
Tech:
• C++, CMake, Golang, Docker, pattern matching, fault tolerance
• Build automation, 97.8% detection accuracy, 28% latency improvement
