Engineering that survives contact with the field.
ISDG builds connected products for clients — embedded systems, wireless, AI-enabled applications, and the fabrication to prototype them. And we build Kalos, a C++ runtime that runs complete backend applications from a single YAML specification.
Guardrails for Vibe Coding
AI collapsed the cost of writing code, but not verifying it. Watch how ADL and the Kalos runtime engine eliminate the security liabilities of generated backends.
The product
Kalos: the spec that runs
Kalos is a C++ application server that interprets ADL — a YAML Application Definition Language — as a complete backend: data model, REST API, role-based permissions, state machines, validation, business rules, workflows, and audit history. One binary. No generated code. The specification isn't documentation of the application; it is the application.
The spec is small enough for a human to review in an afternoon, precise enough for the runtime to enforce on every request, and structured enough for an AI agent to author.
What we build for clients
From prototype to connected product
ISDG combines AI engineering, software, embedded systems, wireless networking, PCB design, and in-house fabrication — so a product can move from idea to testable system without waiting on a dozen vendors.
Embedded Linux & firmware
Yocto builds, bring-up, drivers, update flows, production device software in C++, C, and Python.
Wireless & networking
BLE, BLE Mesh, Zigbee, Wi-Fi, secure provisioning, gateways, field connectivity.
Mobile & application software
iOS, Android, companion apps, operational dashboards, backends on Kalos.
PCB & contract engineering
Board design, system architecture, test fixtures, focused execution when a team needs hands.
Digital fabrication
3D printing, laser work, additive and subtractive manufacturing for practical prototypes and parts.
How we work
Practical engineering for real devices
ISDG is built for teams that need a technical partner who can move between AI workflow, local model, enclosure, board, firmware, Linux image, wireless network, mobile app, and deployment details without losing the whole system picture.
01
Define
Constraints, interfaces, materials, budget, and field conditions before engineering time is spent.
02
Prototype
Working systems in hand quickly: firmware, boards, enclosures, software, AI workflows.
03
Validate
Connectivity, mechanical fit, thermal limits, update paths, and manufacturing assumptions before scale-up.
04
Deliver
Build artifacts, source, documentation, and support paths that make the next revision easier.
