We turn your project
into reality.
CodeGeek H&S designs, builds and runs custom software for US companies: web and cloud applications in .NET, Java, Python, Node.js, Angular and React, with the DevOps to ship them. And when your product touches the physical world, we engineer the firmware, IoT and electronics too. One team, from idea to production.

01 / Software
The whole development lifecycle, in any stack.
We don't just write code — we own the loop. Requirements, architecture, implementation, automated testing, CI/CD, GitOps delivery and production monitoring, adapted to the language and cloud you already use.

02 / Hardware
And when software needs a body.
That's the "H" in H&S. Firmware for microcontrollers, Raspberry Pi systems and custom PCBs — engineered by the same people who build your cloud and apps.
Embedded Firmware
Reliable C/C++ firmware for ESP32 and ARM: drivers, RTOS tasks, low-power modes and secure OTA updates.
ESP32FreeRTOSOTA
Raspberry Pi & Edge
Linux edge devices, gateways and kiosks running containerized apps, managed remotely.
Raspberry PiEmbedded Linux
PCB Design & Prototyping
Schematics, multilayer layout, BOM and manufacturing files — from idea to a working, testable prototype.
Sensors, Power & Testing
Sensor integration, power design and bench test tooling to validate every board revision.
03 / IoT & Hybrid
Where hardware meets software: IoT, end to end.
Most connected projects stall at the hand-off between the hardware vendor and the software agency. We design every link — board, firmware, messaging, cloud and app — so they speak the same language.

06 / Why CodeGeek
One company for the device, the data and the application.
Most projects need more than one kind of engineering. CodeGeek H&S brings software, cloud and hardware under one roof, so your idea goes from a sketch to a working product without being handed between vendors.
Idea to production
We take your project through discovery, design, development, deployment and support, and stay with it after launch.
Hardware and software, together
Firmware, PCBs, cloud and apps are designed by the same team, so the pieces fit from the first prototype.
Senior engineers, no sales layer
A senior lead owns architecture, quality and delivery on every project. You talk directly to the people building it.
A team sized to your project
Frontend, mobile, QA, DevOps and PCB layout specialists join as the scope requires, and step out when it doesn't.
One contract, one point of contact
You sign with CodeGeek H&S LLC, a US company, and keep a single accountable lead for the whole project.
You own everything
Source code, pipelines, firmware, schematics and PCB files are yours, documented and delivered at project close.

08 / FAQ
Questions, answered.
Don't see yours? Send us a message — we reply within one business day.
Ask a questionWhich languages and frameworks do you work with?
.NET, Java, Python and Node.js on the backend; Angular and React on the frontend; Azure and AWS in the cloud. We adapt to the stack you already have.
Can you set up DevOps and GitOps for our existing applications?
Yes. We design CI/CD pipelines, containerize your apps and implement GitOps delivery, then train your team to run it.
Do you also do hardware?
That's the "H" in H&S. Firmware, Raspberry Pi systems, IoT and PCB design — on their own or as part of a complete connected product.
Do you work with manufacturing plants?
Yes. We build test-station software, remote monitoring, SPC and quality dashboards, downtime and OEE systems, MES and traceability, and machine vision, integrated with the equipment and systems you already run.
What hours do you work?
CodeGeek H&S is an Arizona LLC and works US business hours, on Arizona time (MST). When we work alongside your team, we use your tools: your repos, your board, your chat.
Can you work on-site?
Yes. We work remote-first and come to your office or plant for kickoffs, workshops, installations and key milestones. Tucson and Phoenix are a short drive away, and we travel anywhere in the US when the project calls for it.
Who will work on my project?
A CodeGeek H&S team sized to the project, led by a senior engineer who owns architecture, quality and delivery. Specialists in frontend, mobile, QA, DevOps and PCB layout join as the scope requires, and you keep one accountable point of contact.
How is a project priced?
Every engagement is quoted to its scope: a fixed price for well-defined projects, or a monthly rate for an ongoing team. Request a quote and you get a written estimate after the first call.
Who owns the code and the designs?
You do. Source code, pipelines, firmware, schematics and PCB files are delivered to you at project close.
