Turnkey mobile & web apps · $10000 · 8-10 weeks
Your business deserves an app that actually works.
We don't ship MVPs banking on a phase two. We don't take on projects that don't fit into $10k — or we tell you upfront. We don't take everything that comes our way: if we don't see how to do it well, we say no before the start, not in the middle.
Where it usually breaks
Development goes sideways not because everyone is bad
Most of the time it's systemic: scope isn't locked, architecture isn't thought through, communication runs through layers. We've seen it in startups, in enterprise, in agencies — and we built our process so this doesn't happen.
How it usually goes
How we work
Scope drifts, every change becomes a new invoice
Scope locked before kickoff. What's in is in. Extra work is discussed separately, not slipped into the bill quietly.
MVP now, "we'll do it properly later"
Production-ready from day one. We don't build throwaways counting on a phase two — that's not our business model.
Hours tick away, the studio is incentivized to drag it out
Fixed price. We benefit from shipping fast and well — not from stretching support contracts.
Sales sells, a junior builds it
You talk directly to the people writing the code. No middle layers, no lost requirements.
Sales doesn't know what's possible, the client doesn't know what to ask
On the first call we say it straight what fits into $10k, what doesn't, and why. No selling at any cost.
Two codebases, two teams, double the cost
Flutter — one codebase for iOS and Android. A feature ships on both platforms at the same time.
Code handed over — and they vanish
Documentation, access, 30 days of support. Any new developer can pick it up without calling us.
Mobile development
Flutter — and we know why
Not because it's trendy. Because one codebase delivers native performance on iOS and Android — and that solves most of the problems above.
One codebase — two stores
iOS and Android from a single repository. Features ship on both platforms at once. Bugs get fixed once.
Native performance
Flutter draws its own UI through Skia/Impeller. No bridge to native components — 60/120fps with no compromises.
Immutable UI layer
Widgets are immutable by design, composition over inheritance. Code you can read, test and scale.
Routing and architecture
go_router for declarative navigation, layered MVVM, state management without unnecessary dependencies — built-in tools where they're enough.
Web and backend
A modern stack
We know when SSR is needed, when static is enough, when a reactive frontend makes sense — and we don't slap Next.js on everything by default.
Backend
Elysia.js + Bun
Bun is a Rust-based runtime, 3–5× faster than Node on I/O. Elysia gives type-safe routing and validation out of the box. Less code, more speed.
Rust-based · type-safe
Web · SSR
Next.js
When you need SEO, fast FCP, server-side auth or complex server components. SaaS dashboards, marketing, portals.
SSR · RSC · App Router
Web · static + islands
Astro
When the page is mostly static. Landings, docs, blogs — we ship near-zero JS, Lighthouse 100/100.
Zero-JS · Island arch
A common question
Is this vibe-coding?
No. Vibe-coding is fine for a portfolio MVP or a weekend prototype. We build apps that run in production under load — and we understand exactly what we're doing.
Vibe-coding
How we work
AI writes the architecture — the dev doesn't understand why
We design the architecture ourselves, AI speeds up the implementation
No tests, no docs — "it works, doesn't it"
AI helps us cover tests and write docs — fast and painlessly
First bug in prod — no idea where to dig
Clear structure, logs, monitoring — bugs are localized in minutes
Can't scale — have to rewrite everything
Modular architecture — new features don't break old ones
AI generates code → copy-paste → tech debt
AI as a tool in a developer's hands, not a replacement
AI saves us 30–40% of routine time: boilerplate, tests, docs, reviews. That's why it's $10k and not $25k — not because of a "generate" button.
Why so fast
6–10 weeks is realistic
Not because we cut corners. Because we already have most of the building blocks — and AI multiplies our speed at every step.
Production-tested modules
Auth, payments, notifications, file uploads, analytics — all battle-tested in real apps under load. We don't rewrite what's already written.
AI at every step
We use AI not to generate slop, but as a speed multiplier: reviews, writing tests, docs, boilerplate. Control and architecture stay with us.
Design and development in parallel
The designer doesn't hand off mockups "when finished". We work in iterations side by side — no gap between what's drawn and what's buildable.
Scope locked at the start
Before kickoff we lock what's in and what's out. No scope creep mid-flight. Speed comes from honest planning, not crunch.
Design
Honest about design
What's included
UI design built on top of modern component systems. We generate the foundation and refine it for your product. Looks clean, works logically — enough to launch and onboard your first users.
What's not included
A custom design system from scratch, branding, illustrations, animated onboardings. That's separate work and a separate budget. $10k buys you a working product — not a design portfolio.
Why we won't disappear
"Small studios miss deadlines and vanish"
Most studios run on the same math: more clients, cheaper devs, PMs as a buffer between money and code. We're not a studio — we don't have that buffer. We write the code, we talk to the client, we own it when something goes wrong.
Experience beyond agency work
Every team member has worked in startups, agencies and enterprise. We know the difference between code that "works" and code that works under load at 3am.
We don't hire from job boards per project
No random people on the team. No junior rotations, no freelancers plugged in mid-project. The people who start the project are the ones who finish it.
Quality or off the team
There's no room for people who miss deadlines or skip on quality. That's not a corporate slogan — it's the math of a small team where everyone is visible.
A PM without busywork
Yes, we have a Project Manager. They run the tasks, talk to the client, hold the scope. No useless meetings, no posturing. A weekly update — and you see the progress.
?
What about guarantees?We don't take projects that don't fit into $10k — or we say so on the first call. Scope is locked before kickoff. If we screw up, we fix it on our dime. If scope grows beyond what was agreed, we discuss it openly — we don't slip it into the invoice.
?
How do I track progress?A weekly update on a fixed day. A live link to a staging environment from week one — you see the actual product, not slides about progress. Open task tracker if you want to look deeper.
AI in your product
Want AI features in your app?
We can add them. We have a vetted shortlist of models with the best quality/price ratio — and real experience integrating them into production.
Not "plug in ChatGPT" — but solve a concrete problem
Different problems need different models. Chat support, content generation, classification, document search, voice — these are different architectures and different models. We pick by task, not by brand recognition.
Chat and assistants
Support, onboarding, internal bots. Contextual conversations with history.
Semantic search
Search by meaning, not keywords. RAG over your document base.
Generation and classification
Automated form processing, tagging, summarization of incoming data.
Voice (STT / TTS)
Transcription, voice commands, speech synthesis. Multi-language.
Computer vision
Image recognition, moderation, extracting data from documents and receipts.
Any other model
If you have a specific task — tell us. We'll find the right tool for it.
