AI products
Smart assistants that answer from your own knowledge, with sources.
- RAG over your documents and databases
- Streaming answers and voice questions
- Cost control, quotas and content screening
Complex product development
Complex projects.
No compromises.
AI, real-time, mobile and cloud. From idea to production, with the right tool for every layer.
Anyone can build a landing page. Complex systems need someone who knows the tools.
Real-time
Chat, notifications and live updates with WebSockets and Redis. No refresh, no lag.
Streaming
AI answers that appear word by word, live voice, and queues that never get stuck.
Scale
Architecture that grows with your users: autoscaling, caching and databases that hold the load.
Automated deploy
Full CI/CD: every change is tested, built and shipped, including to the app stores.

How I work

- 03
Build with weekly demos
Every week you see something working and give feedback. No surprises at the end.
- 04
Launch and support
Deploy, monitoring and handoff. I stay available after launch.
About me
I'm Gavriel, a developer and infrastructure engineer. I built three production products on my own, end to end: an AI assistant with voice and streaming, a mobile game published on Google Play, and a community platform with real-time chat. I love the hard parts, the things that happen below the screen.
