Cloud architecture
Performance optimisation

Typical Engagement

$20,000 – $120,000

6–16 weeks

Get Started

We write code that works today and is maintainable in three years. Our engineers are opinionated about quality: typed, tested, documented, and deployed with CI/CD from day one. We use Next.js, TypeScript, and cloud-native infrastructure because they're the best tools for building fast, scalable products.

Every engagement includes automated testing, code reviews, and weekly live demos of working software. You always know exactly where we are.

Who It's For

Perfect for these situations

MVPs & New Products

Full-stack delivery from database to deployed UI in weeks, not months.

Legacy Modernisation

Rewrite aging codebases to modern, scalable architectures.

API Development

High-performance REST and GraphQL APIs built for scale.

How We Work

Our process, step by step

Architecture Planning

3–5 days

We design the system architecture, choose the right stack, and set up the project scaffolding before writing a line of product code.

Sprint-Based Build

2–12 weeks

Two-week sprints with working software at the end of each. You get a live staging URL from week one and demo every sprint.

QA & Testing

Ongoing

Automated testing (unit, integration, e2e) runs on every commit. We also do manual QA before each sprint review.

Launch & Handover

1 week

Zero-downtime production deployment, full documentation, and a 90-day support window after launch.

Timeline

What to expect, week by week

Pricing Hint

Investment range

$20,000 – $120,000

Typical range · 6–16 weeks

Scope-dependent. A focused MVP (6–8 weeks) starts at the lower end; enterprise platforms with complex integrations scale up from there.

The Challenge

Legacy Rails monolith with 8-second load times, zero real-time capability, and engineers spending 60% of their time firefighting. They needed a full architectural overhaul without taking the product offline.

Our Solution

We ran dual-track delivery: maintaining the live system while building the new Next.js + TypeScript platform in parallel. Data migration happened in zero-downtime windows. The new system was 4× faster on day one.

FAQ

Common questions answered

Can't find what you're looking for? Get in touch and we'll answer any question directly.

What tech stack do you use?

We're opinionated: Next.js, TypeScript, PostgreSQL, and AWS/GCP for most projects. If you have an existing stack we'll work with it — but we'll tell you honestly if we think a different choice would serve you better.

How do we track progress during the build?

Weekly live product demos, a shared Notion project tracker, and you're invited to every sprint review. You'll always know what's done, what's in progress, and what's next.

Do we get the source code?

Yes — always. From day one. Your code lives in your GitHub repo and you have full access throughout the engagement.

What happens after launch?

We provide a 90-day post-launch support window included in every engagement: bug fixes, performance monitoring, and minor adjustments. After that, we offer retainer and support plans.

Can you work alongside our existing engineers?

Absolutely. Many clients embed us into their existing team. We integrate with your workflow, use your tools, and work alongside your engineers — not in a silo.
