About

Professional summary

I am a Data Analytics Engineer with four years of experience building reliable data products for workforce planning, finance, talent acquisition, and executive decision-making. I specialize in SQL data modeling, analytics engineering, data governance, and data quality.

At ServiceRocket, I have helped move analytics from static spreadsheet reporting to more than 20 production data applications. I build and maintain raw, staging, and modeled data layers sourced from business systems including Jira, Tempo, Lever, HubSpot, NetSuite, and HRIS platforms.

I work regularly with SQL, Python, Looker, REST APIs, and cloud data systems. My approach emphasizes clear metric definitions, appropriate data grain, reconciliation, lineage, role-based access controls, and explicit communication about what metrics can and cannot support.

I also develop AI-enabled data workflows using Claude Code, Google Gemini, and LLM output verification practices. I apply written engineering rules around testing, code review, downstream impact analysis, and traceable evidence before publishing automated outputs.

Earlier in my career, I worked in workforce management and real-time analysis, forecasting staffing requirements, monitoring service levels, and supporting multiple concurrent accounts. I am currently completing an MSc in Data Science Applied to Business Intelligence and am focused on remote analytics engineering and data-focused AI opportunities.

Career history

Senior Data Analyst, Workforce Planning (Analytics Engineering & AI) ServiceRocket Inc.

I design and own analytics transformation layers and KPI models supporting workforce planning, finance, talent acquisition, and professional services decisions. I build modeled data products from Lever, Tempo, Jira, HubSpot, HRIS, NetSuite, and Oracle Analytics Warehouse data, serving more than 20 production applications. My work includes SQL and SuiteQL models, entity hierarchies, semantic KPI definitions, financial and compensation forecasting, and a WorkGraph Explorer linking engagements, sales orders, milestones, epics, stories, people, and worklogs.

I build governance and reliability controls including schema validation, duplicate-header checks, data freshness monitoring, reconciliation audits, source-to-field lineage, metric dictionaries, RBAC, and data minimization. I engineer scheduled API pipelines with pagination, incremental extraction, backoff, retries, caching, and dependency-ordered jobs. I also architect verified AI workflows using Claude Code and Google Gemini, with automated testing, evidence traceability, full-diff reviews, and human review controls for AI-generated recommendations.

Workforce Scheduler-Planner & Real-Time Analyst TELUS International

I built staffing plans and Full-Time Equivalent requirements using call-volume, Average Handle Time, and shrinkage forecasts. I supported operational workforce planning across six concurrent accounts.

I reallocated staff in real time based on changing operational demand and service requirements. This role strengthened my forecasting, capacity planning, and business decision-support experience.

Customer Service Representative (First American Account) TELUS International

I supported the First American account as a Customer Service Representative. I developed customer operations experience while working remotely.

I completed an internal analytics bootcamp, which led to my promotion into workforce planning. This transition established my path into analytics and workforce management.

Workforce Real-Time Analyst (promoted from Customer Service Representative) SYKES (Foundever)

I was promoted within 12 months from Customer Service Representative to Workforce Real-Time Analyst. I monitored schedule adherence, SLA compliance, overtime, and interval-level staffing requirements.

I supported MetLife and Hotels.com operations, providing real-time analysis to help teams maintain service performance. The role built my foundation in operational analytics, workforce metrics, and real-time decision support.
