- Creation of performant frontend applications with Next.js
- Integration of third-party services (authentication, payment, analytics)
- Setup of CI/CD pipelines, monitoring, and observability

- Frontend: React, Next.js
- Backend: NestJS, TypeScript
- Data: PostgreSQL, Prisma
- AI: Azure OpenAI, Qdrant
- Cloud: Azure
🔹 My approach:
I prioritize robust, maintainable, and production-oriented solutions:
