1M+ Row Migration ROI: SQL Server to PostgreSQL
I engineered a Python ETL pipeline to migrate legacy SQL Server data to PostgreSQL, prioritizing cost-efficiency and absolute integrity.
The Problem: High licensing costs and a need for cloud-scalability without risking the "Source of Truth."
The Outcomes:
🔹Savings: Projected 65% reduction in annual licensing fees
🔹Integrity: 1,055,008 rows reconciled with zero violations
🔹Audit: Flagged 24,000+ quality issues (negative prices, invalid emails) during the move
The Impact: Shifted from reactive maintenance to proactive cloud-scaling on AWS/Azure with a cleaner, more reliable database.
Why Me? As an Accountant & Data Engineer, I bring "ledger-style" reconciliation to architecture. I don’t just move data; I audit it.
Open for Migration contracts. Let’s cut your costs.

Vault One is a crypto portfolio dashboard concept that brings together asset performance, portfolio allocation, transaction history, and key financial metrics in one workspace.
I focused on visual hierarchy, information density, and data visualization, using a neutral color palette, subtle UI details, and selective accent colors to keep the interface clean without compromising functionality.
The goal was to make the data easier to understand, not just nicer to look at.
Would love to hear your thoughts on the visual direction and layout!
