Data Pipelines for a Snowflake Data Warehouse

The project included creating 30 data pipelines for a US-based D2C eCommerce client. I replaced as their pipeline provider, reducing their monthly data pipeline cost from $10,000 to $1,500. I also created pipelines for data sources not supported by Fivetran.

Shopify Support for DHL

Shopify did not support pulling order status from DHL. Therefore, I created a reverse ETL pipeline that would pull the tracking information from the customer database and push it back to Shopify. It enabled Shopify to send emails about the order status update and show order tracking information to the customer.

Poker Hand Evaluator

The aim was to create software that would calculate game theory and optimize the play in different situations for poker players. This project was purpose-built for a high-stakes poker player regularly playing in Las Vegas. The software was integrated with PokerTracker 4.

Product Marketing Dashboard

I created a cross-platform dashboard, allowing the client to see product-specific marketing spends and metrics across marketing platforms such as Google, Facebook, Pinterest, TikTok, and Snapchat. This report enabled the CMO to drive higher efficiency for every marketing dollar spent.

Logistics Auditing Function

I set up a system to identify and report potential overcharges on logistics freight applied to orders. It was done by codifying the rate cards of various providers, calculating the billed cost, and comparing them with the contracted cost for each order.
