Developed audience-matching systems achieving match rates of up to 100%, significantly improving campaign efficiency.

Automated data workflows, reducing processing time several-fold and improving delivery timelines for clients.

Built and launched two SaaS platforms from scratch, delivering scalable and reliable solutions for clients in real estate and e-commerce.

The client for this project is reseller of auto parts. His business is very simple, he bought parts for one price and sell them for bigger one. He had a lot of sales managers who receive orders from customers and handle them. Customers was able to order parts from website. However, there was a problem. Sometimes part price is changed while client making is order. And sometimes that causes an issue if margin was like 10-20% and prices is change more than that value. Sales managers had to handle those changes by theirs self. There was a lot of works, because client has different parts distributors.

How I solve that? Pretty simple. At first I builded scraping system. It gather all parts in one big databases from different kind of sources: APIs, Databases, Websites, CSV/JSON files, etc. Main feature is tracking prices changed almost in real time. Then, we build new shop around it with control panel. Client was able to change prices margin depending on disributor, part time. Also the shop had discount system for customers. This automate a lot and, unfortunately for them, my client fired some of sales managers.
