Platform Engineer

Self employed / Freelance • Full-time

Sep 2025 - Sep 2026 • 1 yr

Designed and enhanced a cloud-native asynchronous AI inference platform on Google Cloud, leveraging Python, FastAPI, Cloud Run, Pub/Sub, and Vertex AI. Focused on scalable Producer–Consumer architecture, fault tolerance, high-throughput stress testing, performance optimization, and Grafana-based observability to evaluate system scalability, identify bottlenecks, and improve operational visibility. Developed asynchronous inference workflows using Python, FastAPI, Google Cloud Run, Pub/Sub, and Vertex AI, decoupling request ingestion from model execution. Enhanced system resilience through circuit breakers, dead-letter queue handling, fallback mechanisms, health checks, and Firestore TTL management. Designed and executed Locust-based distributed stress tests using Google Cloud Run Jobs to evaluate throughput, latency, error rates, resource utilization, and autoscaling behavior. Achieved approximately 1,500 requests per second in Producer-side ingestion tests using multiple parallel Cloud Run Jobs. Analyzed Cloud Run concurrency, instance scaling, CPU and memory utilization, network throughput, and Vertex AI capacity to investigate performance bottlenecks. Developed Grafana dashboards integrated with Google Cloud Monitoring custom metrics to visualize request throughput, P50/P95/P99 latency, and Producer–Consumer performance. Integrated OpenTelemetry distributed tracing and custom metrics to improve observability across asynchronous processing workflows.
