Tom Coombs Data & Analytics
FP&A · BI · AI workflows / Open to senior roles

AI-augmented finance systems that turn data into decisions.

Two decades between the finance and data engineering teams — modeling, BI, EPM, and the operational systems that turn transactional data into the reports and dashboards that run the business. Now: applied LLMs in the FP&A stack.

01 · Featured work

Live dashboards. One integrated solution.

Each case study runs against a synthetic SaaS company's centralized database to show what FP&A workflows look like when finance, data, and AI sit on the same stack.

02 · About

The bridge between finance and data engineering.

I spend my time on the boundary where FP&A and BI engineering meet. The data model, the pipeline, the dashboard, and lately the LLM-augmented workflow that makes the end product usable.

Recently I have designed AI-driven finance workflows — taking GL-level data into a centralized database, and out to the dashboards, spreadsheets, and slide presentations that support monthly close, forecasting, and board prep.

Before that, FP&A and BI data orchestration at larger corporate entities. As a former accountant, I care about reconciliation.

Now: open to finance, analytics, and data roles at companies treating finance and intelligence systems as a product, not an end-of-month obligation.
