Some projects stall. Codebases grow fragile, velocity drops, teams lose confidence in what they're shipping, and every change feels risky. ZannoTech has rescued and modernized legacy systems across more than a decade of engagements — diagnosing root causes quickly and executing targeted improvements that restore momentum without costly big-bang rewrites. In a healthcare compliance context, a brittle system was rebuilt from near-scratch into the only HIPAA-compliant web-based activity tracker of its kind in the space — on time, without a working foundation to draw from. For a major fleet management enterprise, a legacy platform was modernized by migrating aging architecture to .NET MVC and WCF services, reducing manual processes and improving operational performance significantly. For a large university's digital marketing platform, a major CMS version upgrade was executed with zero tolerance for downtime — a technically complex migration requiring careful schema migration, module rewriting, and front-end rebuilding in parallel. Across a multi-year digital agency engagement, a regular stream of inherited legacy codebases were stabilized by introducing test coverage, CI/CD pipelines, and architectural patterns that returned teams to confident forward motion. A rescue engagement starts with an honest assessment — no sugarcoating, no overselling. You'll receive a clear picture of what's broken, why, and a pragmatic roadmap to stability and sustainable velocity.

What’s included

• Rapid architecture and delivery assessment with written findings
• Identification of critical risk areas: security, performance, reliability
• Targeted refactoring with measurable before/after outcomes
• Performance profiling and query / API optimization
• Introduction of automated testing (unit, integration, E2E) where missing
• CI/CD pipeline setup for predictable, repeatable deployments
• Observability: structured logging, distributed tracing, and alerting
• Branching strategy and code-review process improvements
• Documented ADRs and handoff materials so gains are permanent
