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.
