We'll take your app to the next level
AI builders excel at proof-of-concept. However, transitioning to a production-ready application introduces critical challenges such as complex deployments, security vulnerabilities, unoptimised costs, and performance bottlenecks.
We specialise in bridging this gap. Whether elevating an existing agentic prototype or engineering custom web and mobile applications from the ground up, we deliver robust, scalable software proudly for Kiwis by Kiwis.

Where agentic-built apps get stuck
Built with Lovable, Bolt, Replit, Cursor, or their like — and hit a wall? The pattern is remarkably consistent: a fast, exciting start, then the same walls. Every one of them is routine work for a professional software engineer.
It works on my machine
The local preview runs fine, but going live is a completely different story — domains, deploys, environments, and databases. We take apps across the line and set up the pipeline properly so future updates stay easy.
Surprise bills
Builder credits burn fast in debugging loops, and usage-based hosting or API keys can spike without warning. We map out what things actually cost, then optimise the app so your bills behave. You may be surprised how much you can save.
Security you can't see
Exposed keys, open databases, and missing access rules are the most common blind spots in builder-made apps. We audit your setup, make the improvments needed, and write the necessary safeguards into the code.
The feature bottleneck
As an AI-built app grows, its codebase becomes an unreadable web of quick fixes. Eventually, adding a simple new feature breaks three old ones or takes days instead of minutes. We refactor and clean your codebase so your product can keep evolving without slowing down.
The bug that won't die
Each fix breaks something else, and the builder keeps circling. A professional engineer reads the code, gets to the root cause, and untangles it for good. We write robust automated tests around the fix, ensuring that exact problem doesn't sneak back into your app.
Stuck at the store gates
Apple and Google frequently reject first-time submissions based on permissions, privacy, or refinement. We've taken apps through both reviews successfully — we know exactly what they look for.
The pattern, documented
The Veracode Global GenAI Security Report evaluated more than 100 leading AI models and found that 44% of AI code-generation tasks produced known vulnerabilities. Even worse, 10 out of 11 models generated code that works perfectly yet failed critical security tests. If a professional hasn’t manually reviewed your app yet, a security check-over is cheap peace of mind to protect your brand.

FAQ
Questions people ask
I built my app with an online builder. Can you take it over?
Yes — rescuing builder-made apps is core work here. We start by reading the code properly, then give you an honest assessment: fix what's there or rebuild the shaky parts, with a fixed quote for either path before anything starts. The code is yours either way.
What does an app rescue involve?
A full review of the code and security first, then the blocking bugs fixed, keys and access locked down, and a proper production deploy. You finish with a plain-English handover document, so you always understand the app you own.
My app works, but the bills keep climbing. Can you help?
Yes. We map exactly what you're paying for — builder credits, hosting, third-party APIs — then rework the expensive parts so costs track your usage. Small architectural changes often cut bills dramatically.
How can you charge fixed prices when agencies quote hourly?
We're a small studio putting modern agentic tooling to work, not a big agency — the overheads that force hourly billing mostly don't exist here. Fixed pricing also forces honest scoping up front, which we prefer anyway: you know the number before we start, and it doesn't move unless the scope does.
What's not included in a fixed price?
Third-party costs you'd pay anyway — domain registration, app-store developer fees, paid services like SMS gateways — and scope we agree to add later. Everything else in the quote is included; if it's in the deliverables list, it's in the number.
Do you only work with Auckland clients?
We're based in Auckland, New Zealand, but we work with clients anywhere in NZ. Almost everything happens over email and a staging link, so location rarely matters.
Is any of the work outsourced?
No. Design, engineering, testing, and deployment all happen locally in New Zealand, carried out by the people you deal with directly. When you email us, you're talking to the hands on the keyboard.
How much experience comes with a build?
Over eight years of professional software engineering across some of New Zealand's leading tech companies and financial institutions. It shows up in the finished app — secure architecture, full automated testing, and engineering judgement you can lean on.
Who owns the code and design?
You do, fully. On final payment everything is handed back to you — the code, the design, and the accounts. Take the repositories wherever you like, or keep us on for hosting and care under a plan — your choice.
How involved will I be during the build?
You're part of the whole build. Each week brings a fresh preview on a private staging link — click through, tell us what to change, and watch it take shape. Your feedback is what shapes the app to your imagination.
Do you design the look and feel, or just write the code?
Both — the aesthetic is shaped with you, not around you: typography, styling, motion, all of it. Professional, high-quality finishes with beautiful, purposeful animations, and every effect carries a reduced-motion fallback so accessibility is never an afterthought.
How long does a project take?
A launch site is typically under a week, a business site 1–3 weeks, and apps or web apps are scoped per project — the fixed quote always comes with a delivery window.
Do you handle the app store submission process?
Yes — that's a core speciality. Apple and Google each require privacy-policy URLs, support contacts, and review compliance before an app goes live. We prepare all of it, submit, and manage the review process through to approval.
Stuck app or fresh idea?
Either way, let's bring it to life. Tell us what you're building — big or small — and a fixed quote comes back within two business days. Or just email hello@nextleveldevs.co.nz.
