Software engineering at Ramp

Self-serve Reserve RBA, reserve account workflows, and bidirectional editing infrastructure.

Software Engineering Intern · Jun 2025 – Present

Self-serve Reserve RBA

I was selected for Ramp’s software engineering internship while still in high school.

I owned and launched self-serve Reserve RBA end to end. Reported product figures: 700+ customers, $72M in exposure, and $33M in assets under management.

I built reserve account workflows, automated bank-letter generation, and an extensible service layer decoupling payment logic from core product flows.

Product figures are a historical snapshot, not live metrics.

Bidirectional editing infrastructure

I developed deterministic bidirectional editing infrastructure between LLM-generated policies and JSON workflow graphs, with canonicalization and round-trip consistency safeguards across representations.
