Solutions Development

// 01 · What we build

Six surfaces. One delivery rhythm.

Web, mobile, APIs, integrations, internal tools, and modernisation — the full custom-software surface, shipped on a two-week sprint cadence with a Friday demo every other week.

SD.01

Web applications

React, Next.js, design-system grounded. Server-rendered where SEO matters, single-page where it doesn't. Built for performance and accessibility from day one.

SD.02

Mobile · iOS & Android

Native Swift / Kotlin or React Native, depending on whether the product needs platform features or shared code. We name the trade-off in week one.

SD.03

APIs & backend

REST, GraphQL, or event-driven. Documented with OpenAPI, versioned, observable, and built to outlast the front-end that called them first.

SD.04

Integrations

ERP, CRM, HRIS, payment, banking. Connector engineering that handles retries, idempotency, schema drift, and the un-fun edge cases under the contract.

SD.05

Internal tools

Admin consoles, workflow engines, ops dashboards. Often the highest-ROI software your engineering team ships — we treat it that way.

SD.06

Modernisation

Legacy refactor, framework upgrades, strangler-fig patterns. Old code re-shaped into something testable, deployable, and inheritable.

// 02 · Solution shapes

Four shapes the product can take.

Custom build, SaaS product, mobile-first, or integration-led. The shape follows the buyer and the business model — not a list of frameworks.

01

Custom build

Bespoke product built for a single organisation — internal tool, customer portal, regulator-specific platform. NAS owns delivery; client owns the codebase from week one.

Best for · one-org product

02

SaaS product multi-tenant

Multi-tenant SaaS for a market — billing, plans, tenant isolation, admin portal, API access. Built to scale beyond the first customer.

Best for · scale market

03

Mobile-first

Native iOS / Android or cross-platform. Field-ops apps, consumer apps, branded engagement apps. Offline-first where the use-case demands.

Best for · mobile primary

04

Integration-led

Connector engineering between systems — ERP, CRM, HRIS, payment, banking. The product IS the integration layer.

// 04 · Sprint cadence

Two-week sprints. Demo every other Friday.

A typical sprint — what happens in each of the ten days. The shape doesn't change between products; the work inside does.

// 05 · What ships with the product

Three artefacts. One hand-off pack.

Every product ships with these three artefacts — not as extras, as part of the definition of done. The ones that decide whether the codebase is inheritable.

// auth.service.ts
export async function signIn(
  email: string,
  pwd: string
) {
  const user = await find(email);
  if (!user) throw Unauthorized();
  return issue(user);
}

Artefact · 01

Tested, typed codebase

TypeScript end-to-end. Unit, integration, and e2e tests required for every PR. Coverage gate at 85%. PRs include their own runbook.

Artefact · 02

PR review & deploy preview

Every change goes through 2 senior reviewers, a preview deploy, and a green CI before merge. No exceptions, including for hotfixes.

Artefact · 03

Design system & library

Figma design system, Storybook component library, accessibility audit. The product's visual language documented to outlive the original team.

// 06 · Methodology

Four phases. Discovery to hand-off.

Discover, design, build, ship. The phases overlap as the team matures; the inputs and outputs of each remain non-negotiable.

01
Discover
2–3 week scoping. Stakeholder interviews, user research, product brief signed by sponsor. Fixed-price, fixed-scope.
02
Design
Design system, key flows, prototype. UX validated with real users before a line of production code is shipped.
03
Build
2-week sprints, demo every other Friday, observability and tests on day one. Production deploys after sprint 3.
04
Ship & hand-off
Hand-off pack: codebase, runbooks, design system, deployment guide. Support transitioned to your team, NAS managed services, or both.

What custom development enables.

Product Velocity · Outcome

Software that ships, scales, inherits

Same product practice, framed as the engineering posture: a codebase you can hand off, a release cadence that doesn't break, and a team — yours or NAS — that can keep adding value past v1.

// 09 · FAQ

Common questions.

Q.01How long is a typical engagement?

MVPs ship in 10–14 weeks. A v1.0 production product runs 16–24 weeks. Long-running product engagements run continuously on a 2-week sprint cadence with quarterly business reviews.

Q.02Do you do fixed-price or time-and-materials?

Both. We fix scope and price on discovery and MVPs. For evolving products we run time-and-materials with a published team rate and a velocity-based forecast updated each sprint.

Q.03What stack do you build on?

Pragmatic. TypeScript on the front-end (React, Next.js); Node, Python, or .NET on the back-end; PostgreSQL or SQL Server for relational, Mongo or Cosmos when document fits; Kubernetes or serverless for runtime — picked per workload, not per fashion.

Q.04Do you provide design as well as engineering?

Yes. Every product engagement includes a design lead. Figma design system, UX research, accessibility audit, and a documented component library — designed to outlive the original sprint.

Q.05Do you support post-launch?

Yes. Every product engagement ends in a hand-off pack and a documented support model — either continued by the original team, or transitioned to NAS managed services, or transferred to your in-house team with a documented runbook.
