• Designed and implemented a production-ready, real-time document processing pipeline using Go, Kafka, and Couchbase, enabling scalable ingestion, enrichment, and full-text indexing of business documents, emails, and logs. • Developed microservices for content extraction, NLP enrichment (TF-IDF keywording, classification, summarization, sentiment, entity recognition), and search, with robust error handling, health checks, and observability for reliable operations. • Built custom NLP modules without LLMs to avoid trivial API-based solutions, focusing on classical techniques for language detection, keyword extraction, and document classification to ensure transparency, efficiency, and production control.
