Custom digital products, built to ship and run.

FeiNiao Dev builds custom software for small businesses and founders, covering AI apps, Telegram bots, mini apps, mobile apps, trading systems, and SaaS dashboards across the full stack.

We believe software's value isn't in the code itself — it's in whether it actually solves problems, runs reliably, and can keep improving. So we don't deliver a feature list. We deliver complete products that launch, operate, and evolve.

On the AI application side especially — from LLM integration and prompt engineering to RAG retrieval and multi-tier fallback architectures — every project is a real, production-grade system.

Every case in our portfolio is a live production system serving real users.

If you have an idea — clear or rough — reach out. We'll walk with you from scoping to launch.
