Agentic AI Alignment

Role: Conversational Designer

Problem: ServiceNow’s enterprise generative AI platform faced critical deployment barriers: multi-turn context drift, ungrounded responses, and susceptibility to adversarial prompt injections. Simultaneously, an escalating taxonomy bottlenecked the Human-in-the-Loop (HITL) data curation workflow, stalling feature validation and product time-to-market. The challenge required designing guardrails for user trust while optimizing internal model training pipelines.

Process: Developed gold-standard datasets, engineered adversarial guardrails, and aligned engineering teams around data taxonomies.

Outcome: Calibrated HITL evaluation UI, driving a 25% increase in cross-functional production throughput.

Methods & Tools: Jupiter Notebooks, ServiceNow Environment, Snowflake, Sreamlit, Prompt Injection, Empircal Testing, Persona Development, Taxonomy Creation, Adversarial Testing, Conversational Design, Python, YAML, JSON, Python.

UX Writing for AI

Close-up of a smartphone displaying a Google search results page with a focus on the 'Analytics' section.

Problem: Google Gemini required massive volumes of highly constrained, gold-standard human-alignment data to mitigate model regressions, safety failure modes, and edge-case behaviors in high-risk query categories.

Process: Engineered thousands of precise training data points, stress-tested model outputs for vulnerabilities, and formulated global documentation to scale ethical AI standards across international teams.

Outcome: Expanded Gemini’s safety guardrails and accelerated data pipeline training velocity by standardizing alignment and annotation workflows across global curation teams.
