Work Experience
Data Science and Analytics Engineer
Google Fiber
- Built SQL pipelines with temporary tables and CTEs to integrate multi-source operational, behavioral, and transactional data. Used Python (Pandas) for quantitative analysis and data transformation, creating unified views of performance drivers.
- Designed hypothesis-driven experimental loops using Python and SQL for quantitative analysis to validate capacity decisions.
- Developed PLX, Looker, and BigQuery dashboards tracking KPIs and communicating system behavior findings through data visualization reports to both technical and executive audiences. Utilized AI tools to accelerate analysis and reporting.
- Partnered cross-functionally with revenue, engineering, and operations to translate ambiguous data requirements into structured research problems and actionable insights.
Data Analytics Engineer
Meta
- Maintained and optimized Python and SQL pipelines ingesting contact center operational data across call volume, agent performance, issue type, managing partner, vendor, location, and language dimensions.
- Built and maintained Tableau dashboards tracking key CX KPIs, delivering data visualizations and reports to leadership and analyst audiences.
- Conducted quantitative analysis on contact center performance trends to surface actionable CX insights for operational decision-making.
LLM Data Engineer
Airbnb
- Applied NLP and LLM pipelines to classify, summarize, and extract structured insights from large-scale unstructured text (regulatory documents, stakeholder feedback) using Python (Pandas, scikit-learn) and SQL.
- Built ETL pipelines integrating behavioral and operational data sources to deliver decision-ready reports and data visualizations. Utilized AI tools to accelerate data processing and insight generation. Surfaced cross-functional insights.
- Designed evaluation rubrics and selection criteria for LLM providers across accuracy, latency, and cost. Defined governance standards for enterprise deployment.
AI Engineering Lead, Product Owner
2Xplore Immigration (LegalLanguageModels)
- Designed and implemented NLP pipelines and evaluation frameworks measuring reasoning accuracy, hallucination risk, and retrieval groundedness across agent workflows using Python. Applied quantitative analysis to benchmark model outputs.
- Built a production multi-agent system with RAG-based semantic retrieval, document classification, and confidence scoring to determine automation vs escalation routing across real paralegal workflows.
- Surfaced and prioritized system failure modes using targeted test datasets and experimental protocols. Utilized AI tools throughout development to accelerate iteration. Led V1-to-V2 redesign to enterprise multi-tenant architecture.
- Produced detailed SQL-backed reports on system performance for stakeholder review.
Customer Insights, Business Analytics Lead
ServiceNow
- Built self-service CX analytics platforms integrating NPS, CSAT, and product adoption data, producing Tableau data visualizations, KPI dashboards, and executive reports in Python and R for cross-functional stakeholders.
- Designed longitudinal causal frameworks quantifying the financial value of CX improvements. Built quantitative analysis models in Python and R, modeling relationships between product implementation, adoption, and renewal outcomes.
- Synthesized customer feedback with operational and transactional data to identify root causes of recurring issues using SQL-based data pulls; developed action plans, produced remediation reports, and measured effectiveness against KPI targets.
- Conducted A/B testing and multivariate analyses, quantifying causal impact on retention with structured hypothesis validation. Utilized AI tools to accelerate analysis and communicated findings through data visualization.
Senior Business Analyst, Workload Analytics
Teradata
- Partnered with data science teams to develop and validate an automated reasoning system that used internal telemetry to recommend database performance and capacity improvements.
- Used SQL to analyze database workload and performance data, translating complex telemetry into actionable findings for technical and business stakeholders.
- Applied Python and R for quantitative analysis and developed data visualizations and proof-of-concept prototypes to demonstrate proposed solutions to key stakeholders.
- Gathered customer feedback and translated business requirements into technical specifications, aligning enterprise needs with product and data science teams.
Experience
Stylin'
https://github.com/IsabelEscobarRivas/stylin-The system creates a persistent StyleProfile that captures user preferences and supports increasingly personalized recommendations. I contributed to the product concept, agent workflow, structured data model, technical architecture, API integration, and prototype development. The project was recognized as a 3rd-place finalist in the Complete AI Hackathon hosted by lablab.ai and Complete.dev.
Proto Circlem, an Attribution and USDC Micropayments Engine
https://github.com/IsabelEscobarRivas/proto-circleI implemented a recency-weighted attribution model that allocates conversion value according to the timing and influence of eligible interactions, while preserving a human-readable rationale for each decision. The application includes an evidence timeline, a payout-status dashboard, REST API endpoints, transaction tracking, and Arcscan links for independent settlement verification.
