Case Studies
Real project results with before/after metrics from our engineering engagements.
Server Optimization Case Study: Database Lag From 5 Seconds to 100ms for $149
A European e-commerce site had 5-second database lag during peak hours, causing 68% cart abandonment. Optimum Web's senior Linux engineer resolved root cause (MySQL misconfiguration + missing indexes + wrong I/O scheduler) in 2 business days for $149. Result: 98% faster database, cart abandonment dropped from 68% to 47%.
Docker Container Crash Loop: Production Back in 47 Minutes for $99
A production e-commerce app went down when a Docker container entered a crash loop — restarting every 3 minutes due to OOM kills. Client team unable to identify cause for 4 hours. Optimum Web engineer connected via SSH, identified root cause (Node.js memory leak — unbounded event listener array) and fixed it in 47 minutes for $99. Zero OOM events in 5 months since.
Telegram AI Bot Case Study: 80% of Support Automated, $1,200/Month Saved — $290 Setup
An online fashion store in Chisinau deployed a GPT-4o Telegram AI bot for $290. The bot was trained on 45 pages of content (FAQ, catalog, shipping, returns). In month 1: handled 82% of messages, response time dropped from 23 minutes to 4 seconds, support labor cost fell from $1,400/month to $200/month. ROI: 7 days.
AWS to Dedicated Server: Hosting Cost From $3,500/Month to $89/Month — Zero Downtime, $299
A SaaS company in the Netherlands was paying $3,500/month on AWS for an app serving 2,000 daily users. Optimum Web migrated the entire stack to a Hetzner dedicated server ($89/month) with zero downtime in 3 business days for $299. Performance was identical (TTFB 180ms → 165ms). Annual savings: $40,920.
