Fixed a priority-client production OOM in the journal search service
Diagnosed and fixed an out-of-memory issue for a priority client in /journal/v1/overview/search by introducing batched retrieval in Metro Facade, bounding per-request memory for large result sets.
Batched retrieval over 500+ recordsNo recurrence since the fix shippedResolved a production OOM issue in the journal search service that had affected a priority client for around 2 months.

Side project
StudyBuddy
Independently built and deployed a full-stack AI tutor answering only from uploaded PDFs, with page-level citations and adaptive exams; Express 5 REST API with an OpenAPI contract generating Zod validation and typed hooks. Benchmarked 5 vision models (Gemini Flash, Qwen2.5-VL 3B/7B, Gemma 3 12B) for PDF page reading: hosted Gemini was 7-30x faster per page (6.9 s vs 46-209 s) than local open-weight models; built a 72-item eval set.
