0 to App Store

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Teams that need a real app in both stores and keep getting six-month discovery quotes.

What you get

One month. Two stores. One standard approach.
A standard architecture for iOS and Android, chosen for maintainability over novelty.
CI with code signing and store submission wired up from day one, so release is a button, not a project.
A published app in the Apple App Store and Google Play at the end of the month.

How it runs

Week 1 scope and skeleton. Weeks 2 and 3 features. Week 4 release hardening and submission.

Embedded OTA Device Management

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Enterprises and medical device makers with devices in the field and no safe way to update them.

What you get

Signed images, staged rollout, and verified rollback.
A fleet console that shows what is running where.
A design that fits your quality system, so the auditor’s question has an answer.

How it runs

Duration: 8 to 12 weeks. We can build on your existing firmware or pair this with NixOS for ARM Devices for fully reproducible images.

NixOS for ARM Devices

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Device makers running a board vendor’s Linux image they cannot rebuild, audit, or trust across a fleet.

What you get

NixOS ported to your ARM device, or ongoing support for a port you already run.
Reproducible images: the same bits on every device, rebuildable from source years later.
A natural pairing with OTA Device Management.

How it runs

Duration: 2 to 6 weeks for a port, depending on board support. Send us one or two devices and we will come back with a plan.

Tech Stack Ownership

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Companies that have been burned by vendor lock-in, supply-chain malware, or a framework that reached end of life three years after they adopted it.

What you get

A top-to-bottom redesign of the stack where you own the frameworks, the SDKs, and if needed the operating system.
A dependency inventory with a risk rating for each item: who controls it, how long it has lived, what replaces it.
A migration plan your own team can execute, sequenced so nothing stops shipping.

How it runs

Duration: 4 to 6 weeks for assessment and roadmap; migration is scoped separately. Assessment first, then roadmap, then optional hands-on migration.

Private AI Deployment & Ops

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Enterprise teams paying a recurring token bill that grows with every seat, or that cannot let data leave the building.

What you get

Hardware sized for your actual workloads, not a vendor’s reference rack.
Open models deployed and benchmarked against the hosted service you use today.
Workloads organized by latency, privacy, and cost, so the right model handles each one.
A $0 marginal cost per token once the system is running. Ops handoff to your team, or ongoing support.

How it runs

Duration: 6 to 10 weeks after a two-week usage audit of your current spend.

XR App Design: Inception to Mixed Reality

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Teams with an idea for a mixed reality experience and no build yet, or a prototype that needs to become a real product for location-based entertainment or enterprise use.

What you get

Short prototypes in days. Enough to put on a headset and decide whether the idea holds.
Full functional applications in 3 to 6 months, depending on complexity and requirements, for LBE and enterprise deployment.
Any ecosystem: Android XR, Meta Quest, WebXR, Unity, or native Apple Vision Pro.

XR Usability Design & Analysis

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Teams building for any XR platform, headset or handheld, who have an existing project that is not landing with users, or a new one they want to get right from the first prototype.

What you get

Analysis of an existing project. A usability review of your XR experience: comfort, locomotion, input, onboarding, and the places users get lost. Findings ranked by impact, with fixes.
Design from scratch. Interaction and spatial design for a new experience, from paper and grey-box prototypes through a testable build, on the platform you choose.
Session recordings and a findings report your team can act on without us.

How it runs

Duration: 2 weeks for an analysis; design from scratch is scoped per project. We can work on-device with your hardware or in our studio.

FDA / Medical Device Cybersecurity

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Device makers preparing a premarket submission who would rather find the holes now than have a reviewer find them later.

What you get

A threat model of the device, its app, its firmware, and its cloud middleware.
A findings report with concrete fixes, prioritized by exploitability and patient impact.
A hardened design you can hand to your filing consultants with confidence, before you spend the $80K on the filing itself.

How it runs

Duration: 4 to 8 weeks. We work inside your quality system and leave the documentation in a form your regulatory team can reuse.

NixOS for Enterprise

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Teams tired of snowflake servers, drift between environments, and a vendor’s roadmap deciding their upgrade schedule.

What you get

Workloads migrated to NixOS: declarative, reproducible, and rollback-safe, so every host can be audited against its definition and rebuilt from source.
An ecosystem with no single company behind it. Like any Linux, it is maintained by a community, which means no vendor can end-of-life your platform or change its license out from under you.
Follow-the-sun support for global teams through our affiliates in Asia.

How it runs

Duration: 3 to 6 months depending on workload count; support is ongoing. We migrate, we train your team, and we support for as long as you want us to.

AI Ops Training

Mon, 01 Jan 0001 00:00:00 +0000

Who it is for

Engineering teams that already have AI coding tools but no shared practice for using them to develop, deploy, and run production systems.

What you get

Hands-on sessions run against your own repositories and pipelines, not toy examples.
A playbook your team keeps: how agents fit into code review, CI, deployment, and incident response.
A review of the permissions your agents and CI runners actually hold, with a hardening list.

How it runs

Duration: 2 weeks. On site or remote. Cohort size: 4 to 8 engineers.

Welcome to Field Notes

Fri, 06 Nov 2026 00:00:00 -0800

This is the technical blog for Razortooth Communications. Expect write-ups from live projects: sizing local inference hardware, threat modeling medical devices, over-the-air update designs that survive a bad image, and moving fleets of ARM devices onto NixOS.

Posts will be tagged to the service they came out of, so if an article describes a problem you have, the offer that solves it is one click away.

Why NixOS

Sun, 09 Nov 2025 10:31:00 -0800

In case you haven’t migrated away from Windows 10 and feel stuck, or saw 11 and feel despair in a major upgrade you don’t need, feel free to reach out to us. Likewise, has the Mac OS “vision” failed to keep you motivated to upgrade when OS X seemed fine as a UX and somehow now feels worse. And yet, you can’t make a move because you need something IT friendly. There are options. Since your developers are already using Linux in the cloud, it is time, possibly, to start to think about moving a larger portion of your teams to a Linux Desktop. Things are tilting slightly this way, finally, in 2025. The year of the Linux Desktop, it has been said.

About

Mon, 01 Jan 0001 00:00:00 +0000

Razortooth Communications, LLC is a boutique agency focused on Design for Technology. Most technology consultancies focus on placing bodies on projects and building out plumbing. We focus on your design needs, customer requirements, and then generate the ideas to build great technology. With practical experience working with both startups and also large enterprises, we can help navigate innovation projects for maximum impact in the market. Rather than focus on the commodity realm of tech, we focus on areas of technology where our customers might have trouble finding the right talent, or are dealing with sensitive core intellectual property and don’t want to outsource to overseas teams. We can work both short term rapid prototyping, as well as long term as a regular part of your team. Please contact us to tell us about your project needs.

AI Devops

Mon, 01 Jan 0001 00:00:00 +0000

AI + ML DevOps

Ready to start building your AI / ML infrastructure in the cloud? When it is time to move out of theoretical designs, we can support your organization in handling the specialized DevOps needed for AI and ML. We can support Azure/OpenAI/AWS clouds.

On-premise / Locally Hosted

For certain types of data and intellectual property, it makes sense to deploy on-premise. This may be true for healthcare or classified research. Additionally, it will often make sense to train models more economically on-premise. Whatever the reason, we can help provide domestic support for your on-premise DevOps for AI and ML onsite or remotely.

Cloud Computing

Mon, 01 Jan 0001 00:00:00 +0000

Platforms

The cloud has made some things better, and some things, to be honest, more complicated. Unless you have a data center, you will need to build services in the cloud. We have experience working with the major cloud platforms: AWS, Azure, and GCP. We can work with serverless environments as well as traditional VM based deployment.

Tools

The landscape for tools and cloud orchestration can be mind boggling. It seems each year there is a new thing everyone is rushing to try to adopt. We will be honest in our recommendations about what will help you and what might hurt your project. Because there is a shortage of strong DevOps talent available to hire to come work for your enterprise, it often makes sense to work with an outside team that can handle the reins on DevOps during an early stage of a project. Our ultimate goal will be to train your team to take over anything we are doing for your project. No hiding the keys from clients. Our success begins when your team feels confident taking over responsibility for the cloud operations.

Digital Media

Mon, 01 Jan 0001 00:00:00 +0000

Audio Production

We have a complete digital audio production studio and can support development of custom, royalty free audio for use in a variety of ways: for web, mobile, embedded device, and any other way that you will need.

Digital Photography

We’ve got an up and coming rock star photographer on our team. Whether you need product shots, nature shots, or something unusual, we can get it done. Post processing can be handled as well. We also have experience in data collection using industrial cameras for use in machine learning applications. Please contact us to discuss your specific requirements.

Embedded Systems

Mon, 01 Jan 0001 00:00:00 +0000

Platforms

There are as many platform choices out there as there are stars. We haven’t seen them all, but we’ve worked with a variety from the majority of major semiconductor companies, reference kits, and ecosystems. Whether it’s a microcontroller or a 64bit ARM processor, we can work with it. If you have specific requirements, let’s talk. We’ve worked with teams to help get products built, tested, and delivered to market.

Medical Devices

Mon, 01 Jan 0001 00:00:00 +0000

Devices

The world of technology has opened many doors for healthcare innovation. We’ve worked with companies on medical devices to help them develop devices that will pass FDA and EU regulations.

Apps

Many of the new medical device designs where use is administered by a patient will often call for an app. Such apps will still need to maintain the same level of security and quality required for the medical device. We can assist in this process.

Mobile Devices

Mon, 01 Jan 0001 00:00:00 +0000

Platforms

We can thank our lucky stars that there are just two major mobile platforms to support: Android and iOS. Throw on wearable platforms. Throw on form factors. Throw on OS variations. Add on I18N. Add in accessibility. Add in Mobile Web. And don’t forget about distribution. It is a recipe for complexity. We can help you cut through the complexity, and narrow down the focus on project requirements.
