Measure, decide, build, hand over
Every engagement follows the same arc, scaled to its size.
Diagnose
We map the flows, read the code and measure what matters: latency, throughput, error rates and cost. Opinions come after the numbers.
Design
We compare options against your constraints and write the decision down, trade-offs included, so it survives team changes.
Prove
The riskiest part is built first, as a prototype or a benchmark, so uncertainty is resolved early and cheaply.
Build
Production code with tests, CI/CD and monitoring. Benchmarks run in the pipeline, so a performance regression fails the build.
Hand over
Documentation, runbooks, pairing and internal talks. Your team owns the result.
