Why Pinnacle
Small, senior and American, multiplied by AI
Pinnacle Refactoring is a small American company. The senior engineers you talk to are the engineers who do the work, here in the United States. We don't hand your code to an offshore team or bury it under layers of account managers.
Instead of adding headcount, we use AI engineering tools such as Claude Code to multiply what a small senior team can do: analyzing legacy code faster, pulling out undocumented business rules, and generating tests that confirm the new system behaves exactly like the old one. Every change is reviewed by an experienced engineer, so AI makes us both faster and more accurate.
Available for: fractional advisory · code audits · specialized part-time and full-time modernization contracts
Consulting & Advisory Services
How we help
Cloud Architecture & Microservices Design
Architecting secure, modern target systems utilizing .NET Core and Blazor with containerized deployments to cloud platforms.
Agile Fractional Leadership
Serving as a Scrum Master and technical advisor to steer internal corporate teams through highly structured, risk-free migrations.
We don't just move your application to the cloud. We re-engineer it to take advantage of it: modern .NET performance, automatic scaling during peak periods, and optimized data access, so it runs faster and more reliably than the system it replaces.
