Principles
How we think about engineering
Six positions that shape every system we ship. They are the reason our work behaves predictably after launch, not just in staging.
Determinism over demos
01We ship systems that behave predictably under real load, not demos that perform under staging. If it cannot hold its budget in production, it is not done.
Contracts before code
02Typed interfaces and interaction protocols are defined before any implementation. Correctness is reasoned about up front, not debugged after the fact.
Observability is not optional
03Every system we ship emits metrics, traces, and structural tests by default. You cannot operate what you cannot see, and neither can we.
Sub-50ms is the floor
04Latency budgets are architectural constraints, not post-launch optimizations. They shape the data path, the deployment topology, and the technology choice.
No black boxes
05We document every decision, every trade-off, and every failure mode. You own the system we build, including the reasoning behind it.
Boring infrastructure, sharp edges
06We use proven tools for the foundation and reserve novelty for where it creates leverage. The boring parts stay boring so the interesting parts can be ambitious.
From uncertainty to verified systems
A deterministic pipeline. Each stage produces an artifact the next stage can verify.
- 01
Architecture
We model the problem as a system: boundaries, data flows, failure modes, and the contracts every component must honor.
- 02
Protocol
We define typed interfaces and interaction protocols before any implementation, so correctness can be reasoned about up front.
- 03
Deployment
We ship infrastructure as code with progressive rollout, observability hooks, and rollback wired in by default.
- 04
Telemetry Verification
We verify behavior in production through metrics, traces, and structural tests, closing the loop against the original contract.
Engagement
Three ways to work with us
Each model is designed for a different kind of problem. Pick the one that matches your stage, or write to us and we will tell you which fits.
Fixed-scope
Defined deliverable, fixed price
We scope, architect, and ship a defined system with an agreed timeline and price. Best when the problem is well-bounded and the outcome is concrete.
- Best for
- Greenfield builds, replatforming, one-shot infrastructure
- Cadence
- 4 to 12 weeks
Retainer
Ongoing engineering capacity
A monthly cycle of dedicated engineering capacity against your roadmap. We operate inside your stack, ship continuously, and own production telemetry.
- Best for
- Evolving systems, scaling workloads, continuous iteration
- Cadence
- Month-to-month, 30-day notice
Fractional
Embedded technical leadership
Architecture review, technical direction, and team enablement on a quarterly cycle. We raise the ceiling of your existing team without replacing it.
- Best for
- Teams that need senior direction, not more hands
- Cadence
- Quarterly, renewable
Performance, measured
Representative figures from systems we operate in production. Sub-50ms execution is the floor, not the target.
- 0.00%
- uptime across operated workloads
- 0ms
- p95 execution latency
- 0k
- requests sustained per second
- 0.0M
- agent tasks dispatched daily
Voices
What clients say after launch
They shipped a system that handles thousands of generation jobs a day without us touching it. The architecture decisions paid for themselves in the first month.
Founder
AI production studio
We replaced three services with one orchestrated pipeline. p95 dropped from 800ms to under 50ms, and the handoff documentation was the best I have seen in a decade.
CTO
Analytics SaaS
The booking flow they built converted immediately. But what actually impressed us was the telemetry. We can see every drop-off in real time and fix it the same day.
