Alexander Z
Informazioni su questo servizio
Stop building legacy code. Get a scalable, enterprise-grade web application built with the latest tech stack.
I specialize in Next.js (App Router) and NestJS 11, focusing on Feature-Sliced Design (FSD) architecture. This ensures your project is not just a "website," but a maintainable, high-speed system.
My Tech Stack:
- Frontend: React, Next.js 15, TypeScript, Zustand, Tailwind CSS, Framer Motion.
- Backend: Node.js, NestJS 11, Express, Prisma 7, PostgreSQL, MongoDB.
- Real-time & Logic: WebSockets (Socket.io), Redis, BullMQ (background tasks).
- DevOps: Docker, GitHub Actions (CI/CD), Vercel, VPS.
What I Can Build:
- SaaS Platforms & Dashboards: Complex data visualization with Recharts.
- E-commerce: Advanced filtering, Stripe integration, and SEO optimization.
- Monitoring Systems: Like my Uptime Sentinel project with Telegram bot alerts.
- Custom APIs: Secure JWT Auth (Access/Refresh) and Swagger documentation.
Why Me?
- Clean Code: No "spaghetti" logicstrictly modular FSD architecture.
- Testing: Unit (Vitest) and E2E (Cypress) testing available.
- Performance: 90+ PageSpeed scores and optimized database queries.
- Lets build something robust. Message me to discuss your project!

FAQ
What is Feature-Sliced Design (FSD) and why does it matter?
Most developers write "spaghetti code" that becomes impossible to update. I use FSD architecture, which organizes the project into clear, functional layers. This makes your application highly scalable, easy to test, and maintainable for years. It’s the gold standard for modern professional developme
Why do you use NestJS instead of plain Express for the backend?
While Express is fine for tiny scripts, NestJS 11 provides a structured, enterprise-grade framework. It ensures your backend is modular, secure by default, and ready for high loads. Combined with Prisma 7, it allows for lightning-fast database queries and reliable data handling.
Can you handle real-time features and background tasks?
Absolutely. I have extensive experience with WebSockets for real-time updates and BullMQ + Redis for complex background processing (like email queues or data monitoring). My Uptime Sentinel project is a prime example of this architecture in action.
Do you provide automated testing for the projects?
Yes. Unlike many sellers, I can cover your business logic with Unit tests (Vitest/Jest) and End-to-End tests (Cypress/Playwright). This ensures that new updates won't break your existing features, saving you thousands of dollars in future bug fixes.
