Software Engineering

Design without engineering is a collection of pretty pictures. Strategy without engineering is a slide deck. At some point, everything has to be built — and how it's built determines whether it performs, scales, and lasts.

Commonwealth Creative's engineering team handles full-stack web development, native and cross-platform applications, headless CMS architecture, e-commerce platforms, and the performance and DevOps infrastructure that keeps it all running. We build what we design, which means there's no handoff gap between creative intent and technical execution. The people who understand why a design decision was made are the same people writing the code.

What We Build

Full-Stack Web Development

We develop complete web experiences — frontend interfaces, backend systems, APIs, databases, and everything that connects them. Whether the project is a marketing site, a SaaS application, a client portal, or an internal tool, we build with the same standards: clean architecture, comprehensive documentation, and code that the next developer can understand without an archaeology degree.

Our frontend work is built primarily in React and Next.js. On the backend, we work with Node.js, Python, and serverless architectures depending on the project's requirements. We choose the stack based on what the project needs, not what's trending.

Native and Cross-Platform Apps

When a project requires a mobile presence, we build native iOS and Android applications or cross-platform solutions depending on the performance requirements and budget constraints. A native app makes sense when you need deep device integration, offline capabilities, or the kind of fluid interaction that only native code delivers. Cross-platform development makes sense when you need to reach both platforms efficiently without maintaining two separate codebases.

We handle the full lifecycle: architecture, development, testing, app store submission, and ongoing updates.

Headless CMS and API Architecture

Modern content management doesn't require a monolithic platform that dictates your frontend experience. We build headless CMS architectures that separate content from presentation — giving your editorial team a clean, intuitive authoring experience while your frontend is free to be whatever the project demands.

We work with Sanity, Contentful, Strapi, and WordPress as a headless backend, depending on the project's content modeling needs and editorial workflow. The API layer between your CMS and your frontend is designed to be fast, cacheable, and resilient.

E-Commerce and Payments Integration

Selling online requires more than a product grid and a checkout button. We build e-commerce experiences on Shopify and WooCommerce with custom storefronts, tailored product discovery flows, subscription management, and payment integrations that handle the complexity of real-world commerce — multiple currencies, tax jurisdictions, shipping logic, and inventory management.

For businesses that need more control, we build custom e-commerce systems with headless architectures, connecting your storefront to the payment processors, fulfillment systems, and ERP platforms your operations depend on.

Performance Optimization and Core Web Vitals

A slow website costs you money. Every additional second of load time increases bounce rates, decreases conversions, and erodes search rankings. We take performance seriously — not as a final polish step, but as a constraint that shapes technical decisions from the beginning.

Our performance work includes image optimization and modern format delivery, code splitting and lazy loading, server-side rendering and static generation strategies, caching at the CDN, application, and database layers, and Core Web Vitals optimization for Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint. We benchmark every build against real-world performance metrics and optimize until the numbers reflect what your visitors actually experience.

CI/CD and DevOps

Reliable deployment isn't a luxury — it's what separates teams that ship confidently from teams that dread every release. We build continuous integration and deployment pipelines that automate testing, building, and deployment so your code goes from pull request to production with minimal manual intervention and maximum confidence.

Our DevOps work includes automated testing pipelines that catch regressions before they reach production, staging environments that mirror production for accurate pre-launch validation, blue-green and canary deployment strategies that minimize risk, monitoring and alerting that surfaces problems before your users notice them, and infrastructure-as-code so your environments are reproducible and version-controlled.

How We Work

Architecture First

Every engineering project starts with architecture. We define the system's boundaries, data flows, integration points, and scaling requirements before writing production code. This upfront investment prevents the kind of technical debt that accumulates when teams start building without a clear picture of where they're going.

Iterative Delivery

We ship in increments, not in one monolithic launch. You see working software early and often, which means you can give feedback on real functionality rather than static mockups. This reduces the risk of building something that technically works but doesn't serve the actual need.

Code Quality and Documentation

We write code for the next person who has to read it — which might be us in six months or someone on your team in two years. Our code follows established style guides, includes meaningful comments where logic is non-obvious, and ships with documentation that explains the architecture, setup, and deployment procedures.

Integrated With Design

Because our engineering and design teams are part of the same organization, the translation from design to code is seamless. Designers and engineers collaborate throughout the build process, resolving implementation questions in real time rather than through a weeks-long feedback cycle between separate vendors.

The Membership Advantage for Engineering

Software development is inherently ongoing. Bugs surface, requirements evolve, browsers update, dependencies release security patches, and your business changes in ways that demand new features. A one-time project engagement handles none of this.

Our membership model means your engineering support doesn't end at launch. Feature requests, bug fixes, performance improvements, dependency updates, and infrastructure changes are all part of the relationship. Your codebase stays healthy and current instead of slowly decaying until someone decides it's time for a full rebuild.

This also means we can be responsive to your business. A competitor launches a new feature? Your sales team needs a custom tool? A partner requires an API integration? You don't need to scope a new project and negotiate a new contract. You tell us what you need and we get to work.

Technologies We Use

We select technology based on the problem, not on preference. That said, these are the tools we reach for most often.

Frontend: React, Next.js, TypeScript, Tailwind CSS. We build interfaces that are fast, accessible, and maintainable.

Backend: Node.js, Python, serverless functions (Vercel, AWS Lambda). We choose the runtime that best fits the workload.

CMS: Sanity, Contentful, Strapi, WordPress (headless). We match the CMS to your editorial workflow.

E-Commerce: Shopify (custom themes and headless), WooCommerce, custom solutions.

Infrastructure: Vercel, AWS, Cloudflare, Docker. See our cloud and infrastructure services for the full picture.

DevOps: GitHub Actions, automated testing, infrastructure-as-code, monitoring with Datadog and similar platforms.

FAQ

How is this different from your web design service?

Our web design service focuses on the complete experience of creating a website — from strategy and visual design through development and launch. Engineering as a service focuses on the technical build: complex application development, API architecture, performance optimization, DevOps, and ongoing technical work that goes beyond what a typical web design project entails. Many clients use both — web design for their marketing site, engineering for their product or internal tools.

Do you work with existing codebases?

Yes. We regularly join projects already in progress — auditing the current architecture, identifying technical debt, and either improving what exists or recommending a migration path when the current stack is holding you back. We'll give you an honest assessment of whether your codebase is worth extending or if rebuilding makes more sense.

Can you build a SaaS product?

We can and we have. From MVP to production, we build software products with the same rigor we bring to client websites — proper architecture, automated testing, CI/CD pipelines, and infrastructure that scales. For SaaS specifically, we handle multi-tenancy, subscription billing, user management, and the operational tooling you need to run a product.

What does engineering cost through your membership?

Engineering work is included in your membership plan. The volume and complexity of work we can deliver depends on your tier. Visit our memberships page for current pricing. For most businesses, a membership is dramatically more cost-effective than hourly engineering consulting or hiring a full-time developer — especially when you factor in the breadth of expertise our team provides.

How do you handle project management and communication?

We work in sprints with clear deliverables and regular check-ins. You'll have visibility into what's being worked on, what's shipping next, and what's in the backlog. Communication happens through whatever channel works for your team — Slack, email, or scheduled calls. We adapt to your workflow, not the other way around.
