# Taaha Bin Mohsin > Senior SWE on Sabbatical for MS CS @ NYU | Ex-Rally UXR, Checkr, Oracle Health | Open to full-time roles from May ’26 Location: New York City Metropolitan Area, United States Profile: https://flows.cv/taaha I’m a senior software engineer currently on sabbatical to pursue my MS in Computer Science at NYU, after six years building production systems across healthcare, compliance, and research operations. Most recently, I was engineer #6 at Rally UXR, where I helped build a research CRM used by enterprise clients to manage over 50,000 interview participants. Before that, I built and maintained fair-chance hiring tools at Checkr, contributing to DoT-regulated workflows, real-time credential verification, and second-chance candidate experiences. I began my career at Oracle Health (formerly Cerner), where I modernized patient-facing wellness and incentive platforms used by millions. I’m using this sabbatical to deepen my expertise in distributed systems, backend architecture, and machine learning systems - and to become a more principled and impactful engineer. Open to full-time software engineering roles starting May 2026.
