Internal operations systems to automate workflows and reduce manual work

Real estate and property platforms (listing management, lead routing, agent tools)

Enterprise dashboards and data-driven decision tools

Booking, order, and service management platforms

B2B platforms with complex permissions, pricing rules, and integrations

Optional add-ons (commonly requested in the US)

UX/UI design system and component library for a consistent brand experience

Performance optimization and Core Web Vitals improvements

Advanced security: SSO, MFA, audit trails, IP allowlisting, WAF configuration

Analytics and event tracking for product decisions (GA4, server-side events)

Content-ready marketing pages with best Shopify website design standards and SEO foundations

Ongoing SLA: monitoring, incident response, and continuous improvements

If your priority is a premium digital presence as well as a robust product, we can align UX, performance, and engineering to meet the same standard you’d expect from the best Shopify web design services and top website design agencies—while keeping enterprise-grade reliability at the core.

What makes a Stralya build different

Project-first delivery

We define success upfront and manage delivery to reach it. The result is a usable, production-ready application—not a collection of unfinished features.

Maintainable engineering

Clean architecture, documentation, and quality gates reduce long-term costs and make future changes faster and safer.

Performance as a requirement

Fast load times and responsive UX are built in, not bolted on—especially important for conversion-focused platforms and Shopify website design services.

Built for enterprise realities

Roles, permissions, approvals, auditability, and integration constraints are handled properly—ideal for SMBs, large enterprises, and mid-market teams working with a serious Shopify ecommerce development company or custom web build partner.

Delivery approach

How we build custom web applications

Our delivery is structured for high-stakes projects common in the US: multiple stakeholders, strict deadlines, and zero tolerance for instability.

We align on objectives, users, workflows, constraints, and success metrics. We translate this into a clear scope, delivery plan, and fixed-price proposal with measurable acceptance criteria.

We design user journeys, wireframes, and UI that match your brand and operational reality. We document key features, edge cases, permissions, and integrations to reduce ambiguity.

We define the technical architecture, data model, and security controls. Environments are set up with CI/CD, observability, and best-practice cloud foundations (AWS, Azure, or GCP).

We build in increments, validate frequently, and test thoroughly (automated + manual). Performance, security, and reliability are treated as first-class requirements—not last-minute fixes.

We prepare deployment, run release checklists, and support go-live. You receive documentation and a clean handover (or we continue as your long-term delivery partner).

We provide monitoring, upgrades, security patching, and feature evolution. This keeps your application stable and future-proof as your business grows.

Find Commonly Asked Questions

A custom web application is built around your exact business needs—features, workflows, roles, and integrations—rather than forcing your team to adapt to generic software or off-the-shelf tools. It’s designed to be scalable, secure, and maintainable from day one.

Yes. Fixed-price is our primary model. We only commit to a fixed price after proper scoping and clear acceptance criteria. This protects your budget and ensures both sides share the same definition of success.

Yes. We can audit the codebase, stabilize the platform, fix critical issues, and take ownership of delivery. If the project is salvageable, we create a recovery plan with priorities, risks, and a realistic timeline.

We build cloud-native solutions on AWS, Azure, or GCP. We design for scalability, resilience, and observability, using modern patterns such as containerization, managed services, and automated CI/CD where it makes sense.

We implement security-by-design: least-privilege access, secure authentication, encrypted data flows, audit logs, and hardened deployments. We also align with your internal policies and any sector requirements (SMB, enterprise, or public sector).

Timelines depend on scope and complexity. Many projects launch an initial production version in 8–16 weeks, followed by iterative enhancements. During scoping, we propose a phased plan to deliver value early without compromising quality.

Yes. We commonly build integrations with CRMs/ERPs, payment gateways, email/SMS providers, analytics, and SSO/identity solutions. Integrations are defined during discovery to avoid hidden complexity later.
