AI-assisted software studio
Ship at the speed new tools allow. With the rigor they don’t bring.
CODE X builds production software with LLMs, agents and modern tooling at the core of how the work gets done — backed by the architecture, testing and review discipline that keeps fast work correct.
Working with
- LLM agents
- Tool use & MCP
- Retrieval (RAG)
- Evaluation harnesses
- Typed contracts
- CI/CD pipelines
What changed
The bottleneck in software has moved. It used to be how fast a team could write correct code. With capable models in the loop, the expensive part is deciding what to build, shaping the system it lives in, and proving it actually works.
That shift is why a small studio can now take on work that recently needed a team — and why the discipline around the tools matters far more than the tools themselves. Anyone can generate code now. Knowing which of it to keep is the job.
What we do
Three ways companies work with us. Most engagements combine more than one.
Product Delivery
Web platforms, APIs and backend systems taken from architecture through to production. We act as your engineering team, or work alongside the one you have, with an AI-assisted workflow that shortens the distance between a decision and working software.

LLM features built to production standards rather than demo standards — agents that use real tools, retrieval grounded in your own data, and the evaluation harness that tells you whether any of it works before your users find out for you.

Independent judgment on decisions that are expensive to get wrong — and help getting AI-assisted development into a team without loosening the standards that keep software correct.

A small studio can offer things a large agency structurally cannot. These are ours.
AI-assisted, engineer-owned
Models generate a large share of the code. A senior engineer owns every line that ships. The review bar does not drop because the typing got faster.
The harness comes first
Types, tests, linters and evaluations are what make speed safe. We put that scaffolding in place early, then let the tools run hard inside it.
The stack follows the problem
We are not loyal to a language. The cost of working in an unfamiliar stack has collapsed, so we pick what fits your system and your team — not what fits our habits.
Direct access
You talk to the engineer doing the work. No account managers, no handoffs, no telephone game between you and the person who understands the system.
Small increments, visible early
Work is broken into pieces you can see running. You are never waiting months to find out whether the thing works.
Accountable in production
The measure of success is a system that runs reliably under real load — not a closed ticket or a delivered deck.
