Software engineer · Open to SDE opportunities

👋 HELLO, I’M

Jason Bu.

A software engineer.
A curious builder.

I’m Jason Bu, a computer science master’s student at the University of Southern California and a computer science graduate of the University of Utah. I focus on backend development, AI agents, and infrastructure, and enjoy turning complex problems into practical solutions.

During software engineering internships at MW Polar and Sunline Tech, I worked on AI workflow automation, banking-system performance, and CI/CD pipelines. Through Maestro, Revieu, and Spreadsheet Engine, I also explore multi-model orchestration, backend architecture, and software systems design.

Outside of coding, I enjoy traveling, cooking, researching AI, and analyzing the stock market. I’m seeking SDE opportunities where I can work with a team to build useful, reliable products.

Software Engineer Intern

MW Polar · Los Angeles, CA
  • Built an AI document-extraction pipeline for purchase orders, inventory checks, duplicate detection, and validated record storage; cut processing time from 5–20 minutes to 30 seconds–3 minutes across 30 test cases.
  • Led an LLM sales-operations agent from warehouse coordination to shipment tracking, removing three manual coordination steps per request.
  • Built CI/CD pipelines with GitHub Actions, Jenkins, Docker, and AWS EC2; automated 134 regression tests and standardized releases.

Multi-model orchestration · In development

Maestro

01

A Python orchestration core for model routing, event-based recovery, budget accounting, and controlled agent execution.

Engineering details

Implemented configuration, event storage, artifact storage, budget accounting, and policy modules. The complete execution loop is still in development; performance targets await benchmark evidence.

Revieu

02

An AI-enhanced discovery and e-coupon platform. Led backend technical design within a six-person team.

Engineering details

Built pgvector retrieval for merchant-grounded review drafts and a Redis/PostgreSQL coupon workflow. Resume-reported internal testing: draft acceptance rose from 61% to 83%, with 5K+ concurrent claim requests and 20% fewer duplicate claims.
