Key Strengths

  • Built and deployed production NLP document-understanding system (extraction, classification, structured outputs)
  • End-to-end ML delivery: fine-tuning on domain data through AWS deployment with Docker and CI/CD
  • Inference-latency reduction via distillation, quantization, preprocessing optimization, async batching, and autoscaling
  • Orchestrated reliable ML/data workflows using Airflow (dependencies, retries/backoff, alerts) with CloudWatch monitoring
  • Reliability-focused evaluation approach: unit tests, synthetic/edge-case simulations, continuous monitoring, drift detection, retraining
  • Pragmatic model/retrieval/prompt selection driven by empirical testing and latency/accuracy constraints
  • Effective collaboration with non-technical stakeholders; delivered operational automation with dashboard-based adoption
