A note from the studio

Good software begins
with good judgment.

We are a small practice of senior engineers. We work where the questions are difficult, the constraints are real, and the quality of the answer matters. AI, applications, systems, algorithms: different disciplines, the same care.

We read the problem before prescribing the stack. We measure before optimizing. And we stay close to the work, from the first architectural decision to the details that make it dependable.

I / Areas of practice

Depth, in five disciplines.

The right expertise.
Not just the familiar stack.
01AI & machine learningFrom promising prototype to dependable production.

Retrieval, agents, model integration, and evaluation. We build the surrounding system as carefully as the model at its center.

LLMs / RAG / Evaluation / MLOps

Explore this discipline
02Application developmentThe interface and everything that makes it work.

Web, mobile, desktop, and command-line applications. We choose the stack for the problem, then carry the work from the first interface to deployment.

Rails / React / SwiftUI / Phoenix

Explore this discipline
03Systems & infrastructureBuilt for the load. Designed for the failure.

High-performance services, distributed systems, and the infrastructure behind them. Explicit trade-offs, measured performance, and clear operational ownership.

Rust / Go / Kafka / PostgreSQL

Explore this discipline
04Algorithms & optimizationFirst principles, where the defaults fall short.

Graph, geometry, numerical, and combinatorial problems inside real products. We model the constraints, establish correctness, and measure the improvement.

Graphs / Search / Geometry / Numerical methods

Explore this discipline
05Consulting & architectureIndependent judgment on the consequential decisions.

Architecture reviews, technical audits, and fractional CTO engagements. A practical diagnosis, an honest view of risk, and a plan your team can execute.
