At Zero Label Cropper, I co-founded and engineer a live SaaS for Meesho and Flipkart sellers. It processes shipping-label PDFs, flags high-return buyers, and turns payout reports into per-order profit.

I built most of the Python/FastAPI backend and the React front end. In the PDF pipeline, I traced memory crashes to PyMuPDF's C-level cache and bounded it, reducing peak memory from 4.2 GB to 0.75 GB on 1,681 pages.

I profiled performance hot paths and checked fixes against the old output. PDF saving improved from 102.6 seconds to 1.4 seconds, while splitting improved from 243 seconds to 26 seconds.

I also built seller-operations and offline-label projects, and completed a data analytics internship with CSRBOX × IBM SkillsBuild. My work spans production Python systems, document processing, cloud services, and automation.
