At Radixweb, I own three core modules for OnPrintShop, a web-to-print and e-commerce SaaS platform. I cut order-listing response time from 10–15 seconds to about one second by changing how data is stored in MySQL and optimizing joins and indexes.
I designed and built REST APIs and an event-driven AWS file-processing pipeline, and created a custom S3 multipart uploader for print files up to 10GB. I also architected an AI agent system used by 100 developers, and led four developers through delivery of a tendering and cost estimation platform for a confidential client.
