Our complete service architecture

We build the entire compute continuum.

From the physics of a 3nm transistor to the control software that stabilizes a city’s power grid: 8 service areas, 26 systems, one architectural foundation.

How it connects

Eight areas, one system.

Each area exists because the one below or beside it sets the limit for the next. Scroll through the stack.

01

Semiconductor & Silicon Architecture

We work at the layer most software never sees: process control inside the fab, the EDA algorithms that turn RTL into a mask-ready layout, and the mixed-signal IP that moves 224 gigabits per second down a single lane.

About semiconductor
02

Cloud & Data Center Infrastructure

A data center is one machine with a hundred thousand parts. We build the controller that programs its switches, the kernel that schedules its cores and tiers its memory, and the orchestration layer that treats every cluster as one fleet.

About cloud
03

Artificial Intelligence & Machine Learning

Model quality is bounded by how fast gradients move between GPUs and how many tokens a serving engine can return per watt. We build the communicators, partitioning schemes, quantizers, and schedulers that set those limits.

Virtualization & Abstraction

Every layer of abstraction costs cycles. We build the hypervisors and isolation runtimes that give workloads the hardware directly, and the migration engines that move a running machine without anyone noticing.

Mission-Critical & Industrial Control Systems

A power grid or a continuous process plant cannot pause for a software update. We build the protocol gateways, historians, controllers, and alarm systems that run these environments with deterministic timing and audited access.

AI Services & AI-Based Products

A model is not a product. What makes it one is the retrieval layer that gives it context, the evaluation harness that proves it is right, the guardrails that stop it when it is not, and the interface that puts the answer in front of the person who has to act on it. We build those systems for the software use cases that carry real operational weight.

About ai products
07

Enterprise Platform & Data Engineering

Most of what an organization calls software is a system of record under load. We treat it the way we treat a switching fabric or a control loop: measure it, find the layer that actually sets the limit, and rebuild that layer. This is not application maintenance. It is the architecture of the systems a business cannot switch off.

About enterprise platforms
08

Technology Consultation & Architecture Advisory

We are asked most often to say what a system will do before anyone commits to it: whether a design holds at the next order of magnitude, what a platform is really worth in an acquisition, and which layer to rebuild first. The answer comes from measurement and from having built the layer in question, not from a reference model or a maturity grid.

About consultation
An engineer holding a test antenna inside a blue anechoic chamber

We are asked most often to say what a system will do before anyone commits to it: whether a design holds at the next order of magnitude, what a platform is really worth in an acquisition, and which layer to rebuild first. The answer comes from measurement and from having built the layer in question, not from a reference model or a maturity grid.

Technology Consultation

A first read on the architecture, written by the engineer who would build it

We take the system as it is measured today, in latency, throughput, yield, uptime, and unit cost, locate the layer that sets the limit, and write down the options with their trade-offs and what each would cost to build. Delivered as a written architecture read with the measurement behind every claim, and the engineer who wrote it available to defend it.
