Data Platform Migration

A Series B fintech company needed to complete a stalled Snowflake migration after losing their data architect mid-project. We stepped in, delivered in 6 weeks, and handed off a clean platform to their new hire.

A migration stalled at the worst possible time

The company had been growing fast — Series B closed, loan origination volume tripling, and their legacy PostgreSQL setup was straining under the load. They'd started migrating to Snowflake with their in-house data architect leading the effort.

Then the architect left. Mid-migration. With partial dbt models, undocumented pipelines, and a PostgreSQL instance that was becoming a bottleneck for the entire business.

  • Half-completed Snowflake migration with no documentation on design decisions or data lineage
  • Legacy PostgreSQL database hitting performance limits — critical loan analytics taking 20+ minutes
  • Four disconnected data stores with conflicting numbers — nobody trusted any single report
  • Leadership needed reliable reporting for board meetings and regulatory compliance
  • New data hire starting in 8 weeks — needed a clean, documented platform to hand off

Six weeks. Zero drama.

We didn't start from scratch — we audited what existed, salvaged what was sound, and rebuilt what wasn't. The goal was never to build the "perfect" architecture. It was to build the right one for a fast-growing fintech that needed reliable data yesterday.

01

Audit & Triage

Spent the first week mapping the existing PostgreSQL schema, the partial Snowflake build, and all downstream dependencies. Identified what to keep, what to rebuild, and what to deprecate.

02

Snowflake Architecture

Designed a clean Snowflake warehouse structure optimized for their lending analytics — loan origination, underwriting metrics, portfolio performance, and regulatory reporting.

03

dbt + Fivetran Pipelines

Built a complete dbt project with modular models, automated tests, and full documentation. Set up Fivetran connectors for every source system with proper scheduling and monitoring.

04

Power BI Dashboards

Created executive and operational dashboards in Power BI — connected directly to Snowflake — replacing the manual Excel reports that were eating 15+ hours per week.

Built on modern, proven tools

Every tool was chosen for a reason — not because it's trendy, but because it's the right fit for a growing fintech that needs reliability, scalability, and maintainability.

From chaos to clarity

Six weeks after engagement start, the team had a fully operational Snowflake warehouse, automated pipelines, documented models, and dashboards that leadership actually trusted. The platform was clean enough to hand off to their new data hire with a two-day onboarding.
