Your fractional engineering team

We build the software. You ship the roadmap. In weeks.

A fractional engineering team for companies that need senior firepower without a full-time hire. We build custom software, ship IoT systems over global cellular, automate the parts of your stack that should already be automated, and run an AI-powered diagnostic that surfaces where your cloud spend is leaking.

/ How the diagnostic works

An AI that reads
your cloud
like an engineer would.

Most consultancies start with a discovery call and a guess. We start with your actual cloud account. Give us a read-only key, and our tool inventories every resource, traces every dependency, and reverse-engineers the architecture you're paying for.

You get a full report and a presented deck — in plain English — showing what you're spending where, what's recoverable, and exactly how we'd fix it. The materials are yours either way. If you want our help executing, we quote a fixed-fee project.

Your bill today vs.

Projected ranges based on published cloud optimization benchmarks (AWS, GCP, FinOps Foundation) and the patterns our diagnostic methodology surfaces. Your actual result depends on your workload — the diagnostic gives you a concrete number.

/ What we do

A senior team for the things on the back of the roadmap.

Six kinds of work, all run the same way: scoped up front, fixed-fee plan, then we ship. Some clients start with a custom build, some with an IoT rollout, some with a cloud diagnostic — most stay for the rest.

01 start here
↗

Build custom software, end-to-end

Web apps, APIs, internal tools, mobile, hardware-integrated dashboards. Senior engineers, embedded with your team, shipping in days instead of quarters — with the architecture decisions made by someone who's done it before.

  • + Custom web & mobile apps
  • + APIs & systems integrations
  • + Internal tools & dashboards
02
↗

Connect physical devices to your software

We design and ship IoT systems end-to-end — from device firmware to global cellular connectivity to the dashboards your team actually uses. One SIM, 170+ countries, zero roaming headaches, and the software layer to make the data useful.

  • + Global cellular IoT, one SIM
  • + Device → cloud pipelines
  • + Fleet dashboards & telemetry
03
↗

Automate the boring parts of your stack

Deploys that used to take a day go to minutes. Our diagnostic flags manual processes, single points of failure, and the parts of your stack a senior engineer would automate first.

  • + Automated deployments (CI/CD)
  • + Infrastructure-as-code rebuild
  • + Auto-scaling + self-healing
04
↗

Refresh products that look stuck in 2018

Take an existing dashboard, marketing site, or app from outdated to modern — without rebuilding from scratch or slowing down your roadmap.

  • + UI/UX refresh on existing code
  • + Marketing site redesigns
  • + Conversion-focused rewrites
05
↗

Tighten up your cloud spend

Our diagnostic connects to your cloud (read-only), uses AI to reverse-engineer your setup, and pinpoints where the waste is. Teams in your bracket are usually over-paying by 30–50%.

  • + Industry-typical savings: 30–50%
  • + Read-only · zero risk to production
  • + Full report inside 72 hours
06
↗

Make your platform handle real traffic

Outages, slow APIs, dashboards that crash during demos. We diagnose where your stack will buckle next, fix what's brittle today, and rebuild what won't survive the next 10x.

  • + Performance & reliability audits
  • + Multi-region & failover
  • + Database & API scaling
/ The timeline

First report in days.
First savings in weeks.
Roadmap in 90.

The diagnostic gives you a clear picture fast. Implementation work happens on a fixed-fee project, so you always know the timeline and the cost up front.

Day 1

30-min intro call. We learn your business; you learn how we work.

Day 2–3

You grant a read-only IAM key. Our diagnostic begins.

Day 4–7

AI sweep + senior engineer review. We surface findings.

Day 8–10

We present your report + deck — quantified savings, timeline, fixed-fee plan.

Week 4–12

We execute. You start seeing the savings hit your bill.

/ Who hires us

Founders and operators whose engineering team is buried in product work.

→

Founders & CEOs

You know the cloud bill is too high. You know the site needs a refresh. You don't want to hire a team to fix it — you want it fixed.

→

COOs & Heads of Operations

Engineering is shipping product. Nobody has time for the work that doesn't have a sprint ticket — until it breaks.

→

CTOs & VPs of Engineering

Your team is great. They're maxed. You want senior help on the side projects without the cost of a full-time hire.

→

Companies between sizes

Past the prototype, not yet at the platform-team stage. The infra and the marketing site and the dashboard all need attention at once.

/ How we work with you

Four promises we make on every engagement.

P/01

Fixed price. Fixed timeline.

No hourly billing surprises. Every project comes with a quote and a date, and we hit them. If we don't, we eat the difference.

P/02

Real engineers on real work.

The person on the kickoff call is the person doing the work. No offshore handoff, no account manager, no junior consultant learning on your dime.

P/03

Plain English, no jargon.

We translate. You'll always know what we're working on, why it matters to the business, and what it's costing or saving — in dollars and hours.

P/04

Hand it back when we're done.

You shouldn't need us to keep something we built running. We document, we hand off, and we leave. Retainers are optional, not implied.
