Key details about this service to help you decide. Generated by Zinn Hub, not the seller.

Tech Stack

React, Next.js, Node.js, FastAPI, PostgreSQL, MongoDB

Turnaround

3–10 days depending on tier
Basic tier delivers a 4-page responsive React app in 3 days. Upgrading to Premium extends delivery to 10 days for larger 10-page builds with design customisation and content upload.

Scope Flexibility

Landing pages up to SaaS MVPs & AI apps
Beyond the entry-level package, the team handles SaaS platforms, AI/LLM integrations, real-time apps, REST APIs, and microservices — suited for startups and growing products.

DevOps & Deployment

Docker, GitHub Actions, AWS, Cloud Run
Includes CI/CD pipeline setup, containerised deployments, and cloud hosting options, meaning buyers can receive a production-ready app rather than just local source code.

Dude’s a beast. No bs, no delays. 100% recommend if you want it done right

Sehr kompetenter und zuverlässiger Entwickler. Er hat das SaaS-Projekt technisch sauber und strukturiert umgesetzt. Besonders positiv: gutes Verständnis für Anforderungen, schnelle Auffassungsgabe und eine nahezu fehlerfreie (bugfreie) Umsetzung. Die Kommunikation war klar, professionell und lösungsorientiert. Änderungen wurden zügig und präzise umgesetzt. Absolut empfehlenswert.
