Cascade Created Duplicate API Endpoints
API has duplicate endpoints with the same path and method after Cascade generated new controller methods. This causes routing conflicts where requests hit the wrong handler, or Spring Boot fails to start due to ambiguous endpoint definitions.
Cascade generated endpoints without checking for existing implementations.
Error Messages You Might See
Ambiguous handler methods for request
Conflicting request mappings
Handler already registered for path
Duplicate endpoint definition
Common Causes
- Cascade added @GetMapping("/api/users") when it already exists in same controller
- Cascade added new controller with overlapping routes as existing controller
- Path parameter mismatches: /users/{id} and /users/{userId} treated as duplicates
- Cascade didn't check base @RequestMapping value on controller class
How to Fix It
Search codebase for duplicate @RequestMapping/@GetMapping/@PostMapping annotations. Verify each unique path is handled by only one method. Review Cascade's generated code and remove duplicate endpoints. Consolidate logic if both versions handle same functionality. Run './gradlew compileKotlin' to detect conflicts.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Get HelpFrequently Asked Questions
How do I find duplicate endpoints?
Use IDE search for @RequestMapping/@GetMapping/@PostMapping. Check both method names and full path (base + method path).
Can two endpoints have same method and path?
No, only one handler per HTTP method+path. Different path params (@PathVariable) create different routes.
