Every case study is based on actual client work. We show the problem, the fix, and the measurable outcome.
A 4.7-million product e-commerce site was grinding to a halt. MySQL CPU at 76%. Every product page triggered full table scans. We fixed 12 critical queries without any downtime.
Product pages failing Core Web Vitals on mobile. CLS of 1.248, slow fonts, render-blocking CSS. We fixed accessibility, performance, and SEO in one engagement.
500+ marketplace emails per week across Amazon, eBay, Walmart, Newegg, and Wish. Manual triage was taking 3+ hours daily. We built an AI agent that classifies, prioritizes, and drafts responses.
200GB buffer pool for a 30GB database. Server was being replaced due to "performance issues" that were actually configuration problems. We cancelled the upgrade and fixed the root cause.
Outdated admin panel with SQL injection vulnerabilities, broken PO templates, and no shipping integration. We rebuilt it from scratch with modern tools and real-time carrier rates.
Email system scanning 100K+ messages with LIKE '%@domain%' queries. Contact discovery taking 2+ seconds per lookup. We added generated columns, composite indexes, and AI classification.
