about

I'm a data analyst and analytics engineer with 5+ years in B2B SaaS. Most recently I worked across Zendesk's go-to-market, finance, product, and customer success teams. I built the dashboards leaders ran on, helped move 13 years of data in a BigQuery to Snowflake migration, and shipped the dbt models behind consumption-based product launches.

Across that work I owned and maintained a large dbt model suite spanning the full analytics platform — writing heavily in SQL and LookML, building in Tableau and Looker, and partnering directly with stakeholders across Finance, GTM, Product, and Customer Success.

The part I care about most is where a number actually changes what someone decides to do.

Eight projects, real outcomes.

Each one shipped to production and moved a number leadership cared about. Tools listed are what I actually built with.

012023 – 2026

Bullseye — Predictive GTM Dashboard

Helped turn Bullseye, a prototype sales play dashboard powered by a machine learning recommendation engine, into an enterprise platform that generated $50M+ in incremental revenue in its first year. Partnered with GTM Strategy, Sales Enablement, Data Science and Data Engineering, and built the metric layer and the Tableau reporting every enterprise account executive used weekly.

RESULT → Win rates on prioritized accounts rose from 50% to 80%

Data Lake Migration: BigQuery to Snowflake

Part of the team that decommissioned the legacy BigQuery data lake and moved 13 years of data to a new Snowflake data lake. Learned dbt, Looker and Snowflake under tight deadlines, reverse-engineered the legacy curated datasets, and rebuilt them as faster, trusted Snowflake datasets. Automated the repeatable ETL work with Python and Snowflake.

RESULT → 35% faster queries; about 40% less manual processing

Consumption SKU Dashboards

Built 6 production dbt models in Snowflake and the Looker dashboards on top of them for consumption-based product launches, giving the Board of Directors a live view of revenue opportunity. Designed the models so later products dropped in without a rebuild.

RESULT → Board-level launch visibility into consumption for product & finance

BI Pipeline Rebuild

The team's Tableau/Looker usage data was unreliable, and leadership was making tooling and licensing calls on it. I rebuilt the pipeline end-to-end in Snowflake with dbt tests and ongoing monitoring — turning a broken one-off into a trusted, maintained data product.

RESULT → restored executive confidence in BI adoption reporting

Customer Success Analytics

Built dashboards giving leadership prescriptive views of churn, satisfaction, and product engagement — surfacing attrition risk and expansion signals across the customer base.

RESULT → Contributed to a $1M revenue gain

Unleash: Conversational BI Slack Bot

Built Unleash, a Slack bot that answers repeat BI questions from our Jira, Confluence and Google Docs. Scoped it to routine questions on purpose.

RESULT → Cut repeat requests by about 40%, giving the team back roughly 10 hours a week

BI Support Desk

Operationalized the BI support desk with templates, checklists and runbooks across Slack, Zendesk tickets and Gmail, so the team ran predictably.

RESULT → Scaled support from about 300 to about 1,000 users

Tableau License Audit

Gemini-assisted audit that flagged six-month-inactive users across 5,500 Tableau seats, plus a Python tool that removed them in bulk.

Let's talk.

I'm looking for my next data analyst or analytics engineer role. Based in Pittsburgh. Open to remote, hybrid or relocating. I'll need an H-1B transfer. I'm already cap-counted, so there's no lottery, and it can be filed any time of year. If you're hiring or can make an intro, I'd love to hear from you.
