Org: Trust and Privacy at Amazon
Team: Alexa Sensitive Content Intelligence
1. Lead organization-wide ML infrastructure cost optimization initiative, architecting solutions to reduce hardware costs from $30M to $20M (33% reduction) for 10K TPS content moderation system. Saving more than 10M $ annually.
2. [Alexa+ Content Moderation] Leading and Developing the Architecture for the content moderation inference platform, that include hosting LLM models for offline response evaluation and (Building RAG infrastructure) embedding models with in-memory vector databases for prompt engineering that will enable LLM to generate moderated response in run time itself, along with context summarisation model. Along with that working on inference servers and libraries for latency & throughput optimizations (VLLM, DeepSpeed, Triton Inference, TensorTR, TGI).
3. Leading the ML front and productionisation of BERT base Content Moderation Models serving as LLM guardrails.
(Model Deployments, ML Infrastructure, Scaling and Hardware Optimisations, Load & Integration Testing)
4. Lead Multimedia project that enabled the team to explore new dimensions and deploy Computer Vision models for images/multimedia sensitivity detection and onboard new clients and use cases apart from existing NLP ones.
5. Developing/Enhancing ML and Data platforms
6. Creating Data Pipeline(ETL) for data annotations and ML model performance metrics generation, utilising spark functionalities
7. Productionisation of text moderation(NLP) and image moderation(CV) ML/DL models
