Sandy Yang

Software engineer and CMU M.S. candidate (Dec 2026) with a backend internship at SLB designing 13 reusable REST APIs on a Python/FastAPI service, and hands-on experience building full-stack AI applications with async pipelines, LLM integration, and automated testing. Available February 2027

Software Engineer Intern - SLB - Houston, TX

(2026-06 - 2026-08)

• Designed 13 reusable REST APIs on a shared FastAPI backend, adopted across 4 product lines and serving both a desktop and a web app, cutting product-testing workarounds from two weeks to one day
• Built a Python/FastAPI service that automates V&V test plans, schedules, and engineering reports, cutting turnaround from two days to one and freeing 0.4 FTE of manual documentation work
• Made product support configuration-driven, so a new product type needs config changes only, and covered the service with pytest unit tests and API integration tests
• Integrated a locally hosted LLM (Ollama) to generate structured test plans from product requirements, with Pydantic schema validation and retry logic that re-prompts on malformed output
