Case Study
End-to-end case studies on distributed systems and production architecture. Each one documents the problem, constraints, decisions, tradeoffs, and lessons learned.
SanketLens: A Multi-Tenant gRPC Observability Engine
A token-scoped ingestion gateway with gateway-enforced tenant labels, multi-level load shedding, and app-scoped opinionated reports — designed to remove repeated Prometheus / Grafana / Collector / Tempo / Loki setup from every backend codebase.
Keyword Extractor
Built a Bangla keyword extraction pipeline that ranks sentence tokens with transformer embeddings and produces keyword-text pairs for low-resource text generation research.
ProcessCache: In-Process LRU Cache for Go
A bounded, thread-safe Go cache package that keeps Redis out of simple hot paths while preserving exact global LRU order, O(1) prefix-scoped eviction, TTL expiration, typed reads, stats, custom sizing, and clean shutdown.
