Legacy .NET Modernization · Production Reliability

Engagements for teams modernizing the .NET they already have.

Every engagement starts with a free diagnostic call and has a fixed price, a clear scope, and a defined timeline. Assess → Stabilize → Prioritize → Modernize incrementally — without the rewrite you don't need.

Legacy .NET Modernization Assessment

$2,500–$7,500

1–3 weeks

Assess what you have, stabilize what matters, and get a prioritized roadmap to modernize incrementally. Strangler patterns, parallel runs, safe cutovers. No big-bang rewrite required.

  • Stabilize-first assessment
  • Strangler plan (what to peel off first)
  • Parallel run + cutover checklist
  • Target architecture + operate-it runbooks
How engagements work

Assess → Stabilize → Modernize incrementally

01

Assess

Free diagnostic call, then a fixed-price assessment of your system: what is stable, what is at risk, and what is worth modernizing.

Prioritized roadmap with effort estimates

02

Stabilize

Stop the repeat offenders first — timeouts, retries, observability, runbooks. The system stops bleeding while you decide what comes next.

Shipped fixes + instrumentation + runbook

03

Modernize incrementally

Strangler patterns, parallel runs, safe cutovers. One bounded slice at a time — without the big-bang rewrite you don't need.

Safe, incremental modernization
