Cloud Computing Researcher

University of Georgia Aug 2024 - August 2025

Designed a cloud platform in Python that runs serverless workflows on discounted, volatile AWS servers while maintaining near-perfect reliability, using cost-optimized checkpointing, workload migration, and adaptive scaling.
Simulated unreliable servers on a 20-node Kubernetes cluster with failure intervals based on AWS reclaim data.
Leveraged MySQL as a source of truth for checkpoints, logging, and compute time for 1000s of daily requests.
Reduced cost by 30%+ with dynamic programming-optimized checkpointing, benchmarked against EC2 pricing data.
