At NXTGEN Analytics, I lead engineering for HIVE, a production NL2SQL analytics platform that lets business users query an enterprise data warehouse in natural language. I designed its agentic core for governed SQL generation, schema-aware entity resolution, and self-correction.
I also built HIVE’s safety layer, including SQL validation, read-only access, row limits, and prompt-injection guardrails. I created an evaluation harness that measures execution match against a golden dataset across multiple LLMs.
At ERNI Philippines, I engineered a production LLM agent that turns unstructured clinical reports into schema-validated JSON, with task decomposition, tool calls, and automatic retry-and-repair. I built field-by-field accuracy evaluation and delivered an aviation data-standards compliance solution involving ontology modeling and API alignment.
Earlier, I built and maintained ETL pipelines and prototyped an NL2SQL system at NXTGEN Analytics. At BillEase, I built backend features for a consumer-lending platform and an Alipay+ payment integration that helped grow the merchant network more than 3x in one year.
