AI / LLM
AWS
AI & RAG Engineering for Enterprise Data
My present-day practice: making private enterprise data usable through LLMs. Document
ingestion and chunking, embeddings and vector search, grounded generation with citations,
and agent workflows that call real business systems — deployed on AWS with cost and
latency budgets enforced in code.
- Stack
- Python, FastAPI, Amazon Bedrock, Lambda, OpenSearch, S3, DynamoDB, Step Functions, Docker
- Focus
- Grounded, auditable AI output instead of unverifiable model guesses
- Applies to
- ERP, CRM, finance and document-heavy operations
More details
Typical scope of an engagement in this area:
- Use-case qualification — deciding what genuinely needs an LLM and what does not
- Ingestion pipelines for PDFs, spreadsheets and database records, with incremental re-indexing
- Retrieval design: chunking strategy, hybrid keyword + vector search, reranking
- Grounded generation with citation tracking so every answer is traceable to a source
- Tool-calling agents with guardrails, retries, timeouts and human-in-the-loop checkpoints
- Evaluation harness: regression tests over prompts, measurable accuracy before and after changes
- Token, latency and spend budgets enforced in code, with structured tracing in CloudWatch
- Least-privilege IAM and infrastructure defined as code
