I build scalable, type-safe web applications with a focus on performance and developer experience. My workflow revolves around the "T-S-P-F" stack: TypeScript, SvelteKit, Prisma, and Fastify.
- Svelte / SvelteKit: Architecting reactive UIs with server-side rendering (SSR) and fine-grained reactivity.
- TypeScript: Ensuring end-to-end type safety from the database schema to the UI components.
- Fastify: Building high-performance, low-overhead APIs with a robust plugin architecture.
- Prisma ORM: Modeling complex relational data and managing migrations with precision.
- PostgreSQL: Optimizing queries, indexing strategies, and ensuring data integrity.
- Docker & Docker Compose: Containerizing microservices for consistent environments across dev and prod.
- Nginx: Configuring reverse proxies, SSL termination (Certbot), and load balancing.
- CI/CD: Automating deployments and maintaining high code quality standards.
In my recent projects, I typically implement a decoupled architecture:
Frontend (SvelteKit)
↔️ API Gateway (Nginx)↔️ Backend (Fastify/Node.js)↔️ Database (Postgres)
- Type Safety: I leverage
zodfor runtime validation and share types between the Fastify backend and SvelteKit frontend via workspace packages. - Performance: Utilizing Fastify's schema-based serialization and SvelteKit's intelligent preloading.
- Reliability: Multi-stage Docker builds to keep production images lean and secure.
