Software engineer at Caliper Corporation who developed an LLM layer for natural-language geographic data queries.

At Caliper Corporation, I developed the LLM-integration layer of a production microservice that lets customers query geographic data in natural language. I owned its prompt engineering and query-generation logic, backend architecture, guardrails, and evaluation framework.

I also built web mapping applications for the SaaS version of Maptitude and web applications for the Federal Highway Administration. My work included AWS infrastructure, CI/CD pipelines, and maintaining geographic analysis desktop applications.

Earlier, I built and tested features for a mobile collaboration app at LifeSize Communications and worked on Java and C# development and verification and validation at Georgian Software Solutions. In a personal project, I built a RAG pipeline with semantic retrieval, Claude API generation, guardrails, and an evaluation harness.
