Web Application Development Perth WA

Nano Solutions builds custom web applications for Perth businesses — from internal portals and customer dashboards to multi-tenant SaaS platforms. Established 2013, WA Government CUAICTS2021 panel supplier (Contractor #225). We specialise in Laravel, React, Vue, cloud-native, hybrid, and on-premises architectures, and we have shipped production web applications used by SLSA, City of Fremantle, Trojan Recruitment, and Procom.

Custom Web Application Development in Perth, WA

Off-the-shelf software solves common problems. Web applications solve your problems — the workflow that doesn't fit any vendor's box, the integration nobody else will touch, the regulatory requirement specific to your industry, the user experience that turns a clunky internal tool into something staff actually want to use. A custom web application is software designed and built to match the way your business actually works, not the way a generic SaaS template assumes it does.

We build web applications across the full stack — backend services and APIs, modern reactive frontends, cloud infrastructure, observability, and CI/CD. Our team has shipped production-grade applications since 2013, and we partner with you from discovery through to long-term maintenance.

What "Web Application" Means at Nano Solutions

A web application is interactive software that runs in the browser. Common patterns we build:

• Customer Portals: Authenticated dashboards where end-users view orders, invoices, tickets, documents, or job status — typically integrated with your CRM, ERP, or operations systems.
• Internal Tools & Operations Platforms: Workflow tools that replace spreadsheets, email chains, and manual processes — built around the way your team actually works.
• Multi-Tenant SaaS Products: Software-as-a-Service platforms with per-customer isolation, billing, role-based access, and the operational maturity needed to satisfy enterprise procurement.
• Marketplace & Booking Platforms: Two-sided platforms with payment, availability, messaging, and reputation systems.
• Data & Reporting Dashboards: Aggregating data from multiple sources with role-based visibility, drill-down detail, and export.
• Public-Facing Services: Citizen-facing portals for government, member portals for non-profits, and high-traffic public information platforms (such as SLSA's BeachSafe).
• Progressive Web Apps (PWAs): Installable, offline-capable web applications that deliver a near-native experience without the cost of separate iOS and Android codebases.

Our Process

Every web application project follows our proven six-phase methodology:

1. Discovery (1–2 weeks): Workshops with your stakeholders to understand business goals, user roles, integrations, and constraints. Output: a project brief, user-story map, and indicative architecture.
2. Design: Technical blueprint — system architecture, data model, API contracts, and UI wireframes. You review and approve before code is written.
3. Build (Agile Sprints): Two-week sprints with working-software demos. You see and steer progress throughout, not just at the end.
4. Test: Automated unit, integration, and end-to-end tests in CI. Manual UAT with your team. Optional penetration testing pre-launch.
5. Launch: Zero-downtime deployment to AWS, Azure, GCP, DigitalOcean, or private/on-premises infrastructure, with infrastructure-as-code, monitoring, and runbooks. Data migration handled with rehearsed cutover plans.
6. Operate: Ongoing support, performance tuning, security patching, and feature enhancements as your product evolves.

Technology Stack

We choose tools based on fit, not fashion. Our core stack:

• Backend: Laravel (PHP), Node.js (Express, Nest), Python (FastAPI, Django) — RESTful and GraphQL APIs.
• Frontend: React, Vue.js, Alpine.js, Inertia.js, Livewire — with Tailwind CSS for styling and TypeScript end-to-end.
• Databases: PostgreSQL, MySQL/MariaDB, Redis, Elasticsearch, MongoDB — selected per data shape and access pattern.
• Cloud & Infrastructure: AWS, Azure, Google Cloud Platform, DigitalOcean, private cloud, and on-premises environments — deployed via Terraform, with full IaC, CI/CD, observability, and monitoring.
• Authentication: Microsoft Entra ID, Okta, Auth0, AWS Cognito, custom OAuth2 / OIDC, and SAML for enterprise SSO.
• Payments: Stripe, Pin Payments, eWAY, NAB Transact — including subscriptions, marketplace splits, and Strong Customer Authentication.
• DevOps: GitHub Actions, GitLab CI, Docker, Kubernetes (EKS, AKS, GKE), automated rollback, and feature-flagged releases.

Why Custom Web Applications Over SaaS?

SaaS makes sense when your problem is well-served by an existing tool. A custom web application makes sense when:

• Your workflow is a competitive advantage — and forcing it into a generic SaaS template erodes that advantage.
• Per-seat or per-transaction SaaS fees outgrow a one-off build cost as you scale.
• You need integrations or compliance behaviour no off-the-shelf product offers.
• You require data sovereignty, audit visibility, or customer-isolation guarantees that a shared-tenant vendor cannot provide.
• You want to build defensible IP rather than rent capability.
• You have already outgrown your spreadsheets, low-code tools, or first-generation SaaS — and the patches are accumulating faster than the value.

Industries We Serve

• Government & Public Sector: Citizen-facing portals, internal workflow tools, and integration platforms — built for City of Fremantle and accessible to all WA Government agencies via the CUAICTS2021 panel.
• Community & Safety: SLSA's BeachSafe (12,000+ Australian beaches), Operations App, and Results competition platform — running in production for years and serving millions of users.
• Recruitment & Workforce: Trojan Recruitment Group's private portal — timesheets, invoicing, e-learning, visa-status checks, and full digital workflow for staff and clients.
• Mining & Resources: Real-time geochemistry QA/QC tooling for remote sites — designed for intermittent connectivity and audit-grade traceability.
• Construction: Procom — O&M manual compilation platform replacing manual document chains for the construction and resource sector.
• Healthcare & Allied Health: Patient-data workloads under APP 11 obligations, including SECCA's sexuality education and counselling platform.
• SaaS & Technology: Multi-tenant production platforms with the security, observability, and operational maturity enterprise customers expect.

What Sets Us Apart

Senior Engineers, Hands On

You work directly with senior developers throughout the entire project lifecycle. No offshore handoff, no junior-engineer churn. The same person who wrote your discovery document is in your sprint demos.

You Own Everything

100% source-code ownership from day one. Infrastructure-as-code under your account. Documentation in your wiki. Take it to any other team at any time — no platform lock-in.

Same Timezone, Face-to-Face

Based in Fremantle. Workshops in person, sprint demos by video, hot fixes deployed in working hours. Code stays under Australian privacy law throughout.

Built-In Security & Accessibility

OWASP ASVS, WCAG 2.1 AA, automated SAST/DAST in CI, and (for regulated clients) IRAP-ready and Essential Eight–aligned architectures. Security and accessibility are baseline, not upsell.

Track Record

Production web applications shipped since 2013. Several of the platforms we built more than five years ago are still running today — and we still maintain them.

Typical Investment
