Turn Legacy Code
Into Speed
Stop fearing your own codebase. We use AI-augmented refactoring to surgically modernize monolithic applications, reduce technical debt, and unlock 10x developer velocity—without the risk of a full rewrite.
The "Strangler Fig" Pattern
Most rewrites fail because they try to boil the ocean. We take a different approach. Inspired by the "Strangler Fig" pattern, we build parallel, modern systems alongside your legacy app, gradually migrating functionality route-by-route.
- Zero downtime migration
- Incremental value delivery
- Risk-mitigated refactoring
- Preserved business logic
Decoupling
Breaking tight dependencies to allow modular upgrades.
Type Safety
Retrofitting strict TypeScript to prevent regression.
Performance
Optimizing core vitals and server-side rendering.
Schema
Modernizing DB access layers with Prisma/Drizzle.
Why Modernize Your Legacy Application?
Legacy application modernization is not just about updating code; it's about business survival. Systems built 5-10 years ago often suffer from "bit rot"—security vulnerabilities, incompatible dependencies, and a complete inability to hire talent who wants to work on them.
At Slickrock Studio, we specialize in React and Next.js migrations. Whether you are stuck on an old Create-React-App, an Angular 1.x monolith, or a jQuery spaghetti mess, we have the tools to analyze, stabilize, and modernize your stack.
Our AI-Augmented Workflow
We don't just type manually. We use large context window LLMs (like Claude 3.5 Sonnet and GPT-4o) via Cursor to "read" your entire codebase. This allows us to understand hidden dependencies and business logic 100x faster than a human contractor, ensuring no feature is left behind during modernization.
