NS360 · Software design & engineering

Designed to launch.Engineered to stay up.

We design, engineer, integrate, secure, scale and maintain software: web, mobile and desktop products, AI in production, cloud platforms and connected systems. One team, from the first sketch to years in production.

01After launch

Most of a system’s life happens after launch.

Launch day gets the attention. Then the real tests arrive. We design and build for those days too, and we stay for them. That is the full circle in our name.

How we look after live systems

Where a system’s cost goes

60%of lifetime cost, on average, comes after launch

Build
40%
Enhancements
36%
Fixes & upkeep
24%

Averages. The share after launch ranges from 40 to 80%, and most of it is new work, not repairs. Robert L. Glass, Facts and Fallacies of Software Engineering (2002), facts 41 and 42.

A system’s life, to scale

A system’s life, to scaleA six-month build, then five years in production on the same time scale. Usage grows after launch, with a spike nobody forecast. Four tests arrive over the years: a traffic spike, a partner API change, a security patch and a handover. Care continues every month.BUILDAFTER LAUNCH01TRAFFIC SPIKE02API CHANGE03PATCH DUE04HANDOVERCARE, EVERY MONTH →LAUNCHYEAR 1YEAR 2YEAR 3YEAR 4YEAR 5
Illustrative: a six-month build and its first five years in production, drawn on the same time scale. Usage is a shape, not data.
  1. Traffic spike

    Traffic nobody forecast.

    How we prepare

    We load-test before launch and set scaling limits and alerts, so a spike shows up on a dashboard before it shows up in support tickets.

  2. API change

    A partner API that changes without warning.

    How we prepare

    Integrations sit behind adapters with contract tests, so a partner’s change fails one test instead of your checkout.

  3. Patch due

    A security patch due on a Friday.

    How we prepare

    Dependencies are tracked and updated on a schedule, and the release pipeline makes a small fix a routine deploy, not an event.

  4. Handover

    The one engineer who understood billing, moving on.

    How we prepare

    Runbooks, architecture notes and decision records live in your repository, so what the team knows stays with the system.

02Capabilities · seven practices

If it involves software, we can design it, build it and look after it.

Every system has layers (interface, application, data, platform, devices), and security cuts through all of them. Seven practices cover the whole stack, and most projects draw on three or four at once.

03Design × engineering

The people who design it are in the room when it’s built.

Every design decision has an engineering cost, and every constraint shapes the design. We keep both in one team, so a screen and the API behind it are decided together, and the product ships looking the way it was designed.

Interface · approval states

DefaultApprove requestpadding 24 · radius full
PendingApproving…
BlockedNeeds a second approverfrom contract: NEEDS_SECOND_APPROVER

The blocked state is on the screen because it is in the contract. Nobody discovers it in production.

API contract · typed end to end

// POST /v1/requests/:id/approve
type ApproveResponse =
  | { status: 'approved'; approvedAt: string }
  | { status: 'blocked';
      code: 'NEEDS_SECOND_APPROVER' };

// the screen cannot compile without handling both
switch (res.status) {
  case 'approved': return <Approved at={res.approvedAt} />;
  case 'blocked': return <NeedsSecondApprover />;
}
An approval button shown in three states (default, pending and blocked) next to the typed API response that defines the blocked state.

04The loop · six stages

Six stages, one team. Then around again.

A project that ends at launch leaves the hardest part with nobody. Ours loops, and every stage leaves you something to keep.

  1. 01 · 000° · Design

    Decide what to build, and why.

    Discovery with the people who will use it, the constraints that matter and the risks worth testing early. Then interfaces, flows and an architecture that fit each other.

    You keep

    • Product brief
    • Clickable prototype
    • Architecture decision records

  2. 02 · 060° · Engineer

    Build it in small, working increments.

    Web, mobile, desktop, backend and AI features, shipped behind reviews and tests from the first week. You see working software, not status reports.

    You keep

    • Source code in your repositories
    • Test suites
    • Weekly written updates

  3. 03 · 120° · Integrate

    Connect it to everything it depends on.

    Payments, identity, ERPs and CRMs, data pipelines, devices and third-party APIs, with contracts, retries and monitoring, so an outage elsewhere does not become yours.

    You keep

    • API contracts
    • Integration tests
    • Failure-mode notes

  4. 04 · 180° · Secure

    Make security a property, not a phase.

    Threat models for the parts that matter, least-privilege access, secrets handled properly and dependencies watched. Reviewed before launch, not patched after an incident.

    You keep

    • Threat model
    • Access map
    • Security review notes

  5. 05 · 240° · Scale

    Prepare it for the load you expect, and the load you don’t.

    Infrastructure as code, observability, performance budgets and load tests sized to your real growth, with costs you can predict.

    You keep

    • Infrastructure as code
    • Dashboards and alerts
    • Capacity plan

  6. 06 · 300° · Maintain

    Keep it healthy for years, not weeks.

    Upgrades, patches, restore tests and small improvements on a schedule. When the next version starts, the loop begins again, with everything learned in production.

    You keep

    • Runbooks
    • Upgrade calendar
    • Handover documentation

05In production

AI, infrastructure and security, held to production rules.

  • Applied AI

    Measured before it ships.

    Evaluation sets built from your real cases, budgets for cost and latency, citations where answers must be checked, and a human on anything consequential.

    Applied AI & Data

  • Infrastructure

    Readable, repeatable, affordable.

    Everything as code, observability tied to what users feel, load tested against real growth, and recovery that has actually been rehearsed.

    Cloud & Platforms

  • Security

    A property, not a phase.

    Threat models for what matters, least-privilege access, secrets handled properly and dependencies watched. Reviewed before launch, not after an incident.

    Security & Reliability

Station-keeping · two systems, three years

Low orbits decay. So does software left alone.

Two systems launch on the same day. One is left alone. The other gets small, scheduled corrections: updates, rotations, restore tests, access reviews. We do the dull work on a calendar, so it never becomes an emergency.

Health of two systems over the three years after launchThe system that is left alone declines as a dependency falls behind, a certificate expires, knowledge leaves with a person and a rewrite starts to look cheaper. The system that is kept stays level through small, scheduled corrections.LAUNCHM6YEAR 1M18YEAR 2M30YEAR 3HEALTHA dependency falls behindA certificate expiresKnowledge leaves with a personA rewrite starts to look cheaperKEPTLEFT ALONEYEAR 3.0

06Selected work · 4 products

Live software, and the hard problem inside each one.

Each product here is live, and each has a difficult engineering problem at its core. We describe the problem and how the product answers it. No borrowed metrics.

  1. W-01 · Consumer utility · Native macOS · On-device security checks

    SiftSpace

    A Mac cleaner where every decision can be undone.

    Cleaning a disk means deleting files, and one wrong guess destroys someone’s work. The app has to be ruthless with clutter while making loss structurally hard, and do it without sending file data anywhere.

    Glutfit

    Six fitness services behind one account.

    A fitness routine touches bookings, subscriptions, retail and health data. Putting all of it in one product means each service keeps its own rules while the person sees one account, one history and one set of goals.

    EnvVault

    Secrets and configuration, from the edge to the running process.

    Secrets leak through the gaps between tools: a pasted `.env`, a CI variable nobody rotates. One API has to serve every surface without widening those gaps.

    Every stage leaves something you keep.

    Decision records, runbooks and documentation are delivered as the work happens, not promised for the end.

    Approach

  5. 05

    You will always know where things stand.

    A written update every week: what shipped, what’s next and what’s at risk. Problems are raised early, in writing.

    Approach

  6. 06

    Security is part of done.

    Least-privilege access, reviews and dependency scanning on every engagement: before launch, not after an incident.

    Security

  7. 07

    We will tell you when the answer is no.

    If AI, a rewrite or a new service is the wrong tool for your problem, we say so and explain why.
