Deployed a containerised FastAPI inference service (Docker → ECR/ECS) and integrated it with the SPA to enable real-time GL/product recommendations and end-to-end latency benchmarking (tested on ~3.4k tenant entries), laying the groundwork for CI/CD and production roll-out.
Processed and standardised large-scale production data (~1.4M records) and revamped the clustering pipeline using HDBSCAN with GPU-accelerated embeddings, producing high-quality clusters and surfacing 300+ candidate catalogue items to expand mapping coverage.
Applied contrastive fine-tuning and rigorous evaluation pipelines (top-k accuracy, MRR, percentiles) to boost model performance ≈40% and achieve 94.5% top-3 median accuracy on recent tenants; instrumented centralised logging for inference and UI usage to improve observability.
