What we do
Engineering across the whole stack
One team that can take a product from an empty repository to a system serving real users — and stay with it after launch.
Web platforms
Product surfaces that stay fast as the data grows — server-rendered, accessible, and instrumented so you can see what users actually do.
Mobile applications
iOS and Android from one codebase where that is the right call, and native where it is not. Shipped to the stores, not handed over as a build.
Backend & APIs
Services designed around the failure modes, not just the happy path. Typed contracts, real observability, and load numbers we can defend.
Real-time & media
WebRTC, streaming and low-latency transport — including the parts nobody writes blog posts about, like relays that work under restrictive networks.
AI systems
Models put to work inside a product: retrieval, agents and inference pipelines with evaluation attached, so quality is measured rather than assumed.
Infrastructure & SRE
Deployment, monitoring and the on-call rotation. We run what we build, which is why we build it to be runnable.
The stack we build on

- React
- Next.js
- Go
- Rust
- Python
- PostgreSQL
- Kubernetes
- Terraform
- Flutter
- WebRTC
- Kafka
- ClickHouse
- Redis
- GraphQL
- Docker
How it works
From conversation to production
A predictable path, whatever the project is.
- 01
Discover
We take the time to understand the business problem, the constraints and what success actually means before proposing anything.
- 02
Architect & design
System architecture and interface design decided together, so the thing that gets built is buildable and the thing that gets drawn is shippable.
- 03
Build
Short cycles with working software at the end of each one. You see progress continuously, not at a reveal.
- 04
Ship & operate
Deployment, monitoring, and the ongoing work of keeping a live system healthy as it grows.
