260 Hours Saved with Claude Code: Audit & Security Timeline Cut by 1 Month

Real EstatePoland

Case study summary

The client needed to modernize a mission-critical Building Management System (BMS) whose core module relied on outdated technologies and contained 87 security vulnerabilities. The challenge was to upgrade the platform without disrupting production while preserving years of accumulated business logic. VM.PL delivered the project under a Fixed Price model, using Claude Code and GitHub Copilot to accelerate legacy code analysis, refactoring, testing, and security improvements. The result: 25-30% faster delivery, 220-264 engineering hours saved, all vulnerabilities eliminated, and a future-ready platform with lower technical debt.
