Built a 4K-capable distributed video-rendering platform with FastAPI backend, async task queues, and distributed GPU workers supporting 50+ GL-Transitions shaders. Compiled a custom FFmpeg build with GL-Transitions streaming pipelines to cut peak memory usage ~40%, enabling 4K rendering on mid-tier GPUs. Resolved GPU bottlenecks by autoscaling consumers on queue depth and adding priority queues, improving turnaround under burst load.

Added a remote WebSocket StoreAdapter enabling real-time multi-user annotation sync with conflict resolution for synchronized sessions. Optimized SVG/TypeScript rendering logic to achieve smooth 60fps rendering under high annotation counts through spatial indexing and SVG optimizations, preventing annotation overlap and improving interactive performance.

Built a distributed hash-testing platform for authorized security research, integrating Hashcat with a BOINC-style volunteer GPU grid and secure job dispatch. Solved throughput bottlenecks by tuning kernel batch sizes and scheduling, increasing hashes/sec without adding hardware. Implemented capability-aware routing and priority queues to keep urgent jobs moving while maintaining fairness.

Work Experience

AWSEKSLambdaS3Terraform+16

Senior Software Engineer (Backend & Platform)

2023 - Present
  • Decomposed a monolith into 6 Docker/EKS microservices, cutting deployment time from hours to minutes with zero-downtime releases.
  • Instrumented Jaeger tracing and Prometheus/Grafana dashboards to cut MTTR from ~45 minutes to under 10 minutes by isolating cross-service latency.
  • Implemented Temporal workflows with idempotency and compensation to reduce failed cross-service operations by ~80% (from 150/day to <30).
  • Reduced core query latency from 30s+ to under 1s through indexing, connection pooling, and service decomposition (Postgres/Redis).
  • Built GitHub Actions + ArgoCD CI/CD pipelines with security gates, canary releases, and blue-green deployments supporting 99.9% availability.
  • Reduced AWS spend by ~25% via EKS node rightsizing, autoscaling tuning, and spot instances without SLO impact.
  • Stabilized 500-800 RPS burst windows with rate limiting, queue-based smoothing, and graceful degradation across 100k+ DAU platform.
