About this gig

Stop patching symptoms. Let's fix the root cause.


Most bugs are results of poor architecture. I don't just "fix" code; I apply systemic engineering to ensure the issue never returns. Leveraging my experience in building the QuCore Dynamic ecosystem, I provide deep-level debugging for high-performance applications.


What I solve:

  • Next.js Hydration & SSR Conflicts: Solving complex mismatches between server and client states.
  • Memory Leaks & Performance Bottlenecks: Ensuring 60 FPS and optimized resource usage.
  • Auth & Security Flaws: Fixing JWT, RBAC, and session management issues using production-grade standards.
  • Type Integrity: Eliminating "any" and fixing complex TypeScript interface conflicts.


I follow a strict "system-first" approach: clean fixes, zero-semicolon policy (if requested), and maintainable architecture.

I am a Full-stack Engineer specializing in high-performance web systems and mathematical modeling. My expertise includes Next.js, Node.js, and PostgreSQL, with a focus on scalable architecture using Kafka and Redis. I bridge the gap between complex math (Calculus I-III) and graphics, developing tools like the ORBITA orbital simulator (Three.js/GLSL). I follow strict engineering principles: architectural clarity, determinism, and 60 FPS performance. I build production-ready systems, from EdTech platforms to scientific visualizations. Let's build something complex!
