TAHLEEL

Turns plain-English business questions into validated T-SQL through a 17-node DAG workflow, then renders the answers as live dashboards and scheduled reports.

Dense vector search and BM25 fused by Reciprocal Rank Fusion, cross-encoder reranked, and gated in CI by 60+ automated evals so a regression never ships.

Every voice turn is intent-classified and routed to RAG, a tool call or a direct answer, holding sub-second audio latency while tracking p50/p95/p99 and cost per stage.

A small model taught to emit schema-valid JSON through QLoRA adapters and DPO preference alignment, at a fraction of full fine-tuning cost.

Fifteen cloud builds end to end: ALB/NLB autoscaling, multi-tier VPC deployments, serverless pipelines and automated cost optimisation, all provisioned as infrastructure-as-code.

An 8-node LangGraph that prospects a niche, crawls and researches each company, extracts C-suite contacts, then halts for human approval. It's checkpointed, so a run survives a restart.
