Project details
If your React or Next.js application feels slow, heavy, or inefficient, I can help you optimize it properly.
I specialize in identifying performance bottlenecks in real-world SaaS and web applications. This includes unnecessary re-renders, inefficient state management, oversized bundles, poor Core Web Vitals scores, and slow API interactions.
My approach is structured and data-driven. I analyze your application using profiling tools and performance metrics, then apply targeted improvements that make measurable impact.
Typical optimizations include:
• Reducing unnecessary component re-renders
• Improving bundle size and code splitting
• Optimizing state architecture
• Enhancing loading performance
• Improving Lighthouse and Core Web Vitals scores
• Optimizing Next.js SSR and rendering behavior
The result is a faster, cleaner, and more scalable application ready for production.

About Bernardo
Senior Full-Stack Engineer | Secure SaaS, AI Systems & Scalable Archit
Portimao, Portugal - 9:13 pm local time
I'm a Full-Stack Engineer specialized in .NET (C#), Kubernetes, and modern web stacks. I help companies design, build, secure, and scale applications that are ready for real-world traffic.
What I can help you with:
• Design and build ASP.NET Core Web APIs
• Architect modular monoliths and scalable backend systems
• Kubernetes cluster setup (from scratch or production hardening)
• Secure, production-grade Kubernetes environments
• CI/CD with GitHub Actions
• Docker & containerization
• SQL Server / PostgreSQL / MongoDB database design
• React / Vite / Tailwind frontend development
• Full-stack application development
• RabbitMQ & distributed systems
• Cloud deployments (GCP & self-managed infrastructure)
I don’t just write code — I design systems with performance, security, and long-term maintainability in mind.
If you need someone who understands both development AND infrastructure, we should talk.
