High Performance

Built on modern edge networks (Vercel/AWS). Sub-second load times, efficient caching, and code-splitting ensure your app feels instant.

Verified

Clean Architecture

We write maintainable, typed code (TypeScript). Modular components, automated testing, and strict CI/CD pipelines prevent technical debt.

Verified

Data Integrity

Reliable database design (SQL/NoSQL). We ensure your data is structured logically, queried efficiently, and backed up reliably.

Verified

UX First

Complex logic doesn't mean complex interfaces. We build intuitive, accessible UIs that make powerful features easy to use.

What clients are saying
Case Evidence.

CLI_TES_104
"I've worked with ONE° on several projects over the years, and it's always been a positive experience. Building a website can get complicated, especially with multiple stakeholders involved, but they bring a steady, can-do approach that really helps keep things moving. They listen closely to what clients want and offer thoughtful, practical solutions—especially when the challenges aren't straightforward."

[FAQ]

Frequently
Asked.

Our core stack is TypeScript, React, Next. js, Node.js, and PostgreSQL (via Supabase). We deploy on Vercel or AWS. We choose tools based on your project needs — not trends.
Yes. Once the final payment clears, you own 100% of the codebase and intellectual property. We hand over the full repository, documentation, and deployment credentials — no ongoing licensing fees.
An MVP typically takes 8–12 weeks. Larger platforms can take 4–6 months. We demo progress every 2 weeks so you always know what's been built and what's next.
Yes. We integrate with CRMs (HubSpot, Salesforce), payment systems (Stripe, PayPal), ERPs, email platforms, and any service that provides an API. We've built custom integrations for dozens of platforms.
Yes. We're based in Ulverstone, Tasmania and work with businesses across Australia, the US, and Canada. Custom app development works well remotely — we communicate through weekly video calls, Loom updates, and Slack throughout the project.
Custom web apps start from $8,000 AUD for a simple app with user authentication. More complex apps with integrations and dashboards range from $15,000–$60,000+.
We provide 30 days of post-launch support with every project. After that, we offer monthly maintenance retainers for updates, bug fixes, and new features.
MVPs typically range from $15,000 to $40,000. Full-scale platforms start at $50,000+. We provide fixed-price quotes based on a detailed technical scope document agreed before work begins.
Yes, but we do a paid technical audit first. We assess code quality, security vulnerabilities, and technical debt before agreeing to maintain or extend an existing codebase. This protects you and us from surprises.
We build responsive web apps that work perfectly on mobile. For native app store apps (iOS/Android), we use React Native — which shares 70%+ of code with your web app, saving significant budget compared to building two separate apps.
Security is built in from day one: proper authentication (Auth0 or NextAuth), role-based access control, input validation, secure API design, environment variable management, and regular dependency audits. We don't bolt security on after the fact.
Book a free discovery call at onedegree. studio/book. We'll talk through what you're trying to build, what's been tried before, and what the right technical approach looks like. You'll get a detailed proposal with fixed pricing within 48 hours.
Yes. We've built SaaS platforms, internal tools, client portals, and booking systems. We help with the full product: UI design, API, database, hosting, and feature development.
