Cover image for 1M+ Row Migration ROI: SQL
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.

My latest build turns that chaos into a sleek, interactive Insurance Application Summary Dashboard built for speed, insight, and control. Traditional reports hide insights behind endless spreadsheets. This dashboard flips the script, it reveals the story instantly: Clarity isn’t cosmetic, it’s profit. Good reporting tells what happened. Creative reporting shows where to act next. By blending storytelling, interactivity, and business logic, this becomes a true decision engine for underwriting teams. If approvals still take 75 days, your reporting is the bottleneck. I build data products that turn chaos into profit-driving clarity. Now open to projects merging data strategy + design + visualization for faster, smarter decisions. 📊 Explore the vision. 💬 DM to discuss your toughest data challenge.

Cover image for Retail Inventory & Sales Forecasting
Retail Inventory & Sales Forecasting Engine: This project involved building a predictive engine designed to solve the "stockout vs. overstock" issue. Using time-series analysis on past sales cycles, seasonality, and market trends, I created a model that predicts future inventory needs with high precision. It provides business owners with a clear "buying guide" for the upcoming quarter. Key Result: Reduced potential waste from overstocking while ensuring top-selling items never go out of stock, optimizing cash flow management.

Cover image for Customer Churn Prediction & Retention
Customer Churn Prediction & Retention Analytics: Helps subscription-based businesses lower their attrition rates, I developed a "Churn Warning System." The model analyzes user engagement signals to flag customers who are showing signs of leaving before they actually cancel. This gives the business a proactive window to reach out with retention offers and save the account. Key Result: Identified the top 3 drivers of customer loss, allowing for data-driven retention strategies that protect long-term revenue.

Cover image for Automated Data Extraction & Invoice
Automated Data Extraction & Invoice Processing Built a custom automation pipeline to eliminate the "manual data entry" bottleneck in accounts payable. Using OCR (Optical Character Recognition) technology, the system "reads" scanned invoices and PDFs, extracts key financial data, and formats it into a structured database or Excel sheet automatically. Key Result: Replaced hours of manual typing with a 95% faster automated process, virtually eliminating human entry errors.
