Specifications are
defined as we build.
Monthly flat-rate engineering
that keeps up with your business.
You do not need to decide everything upfront. We deliver a working system in as little as two weeks and keep improving it while you use it. That is the most rational way to build in an uncertain era.
* No hard selling. Ever.
Ultra-efficient engineering for the AI era.
We combine AI-generated code with human logical thinking to bring your business to life at exceptional speed.
The Old Way Manual Work & Waterfall
The man-month trap
Everything is hand-coded, so every change adds time and cost.
Rigid requirements
Waterfall means defining everything before building, which cannot keep up with today's market speed.
Fragmented development
Web and apps are built with different languages and teams, doubling management cost and bug risk.
Finite Field AI x Agile
AI-powered speed
AI drafts the code instantly. Engineers focus on complex design and experience quality to maximize speed.
Specs evolve as we go
We prototype quickly and decide specs while touching real screens, minimizing rework.
Web + App
Flutter and modern tooling ship web and apps from one codebase, minimizing maintenance cost.
Three benefits of a flat-rate plan
From one-off builds to a growing asset
You own all rights, so you can invest with confidence.
In conventional development, a system starts aging the moment it ships. Our approach is different. We add features as your business grows so the asset keeps gaining value.
All source code rights belong to you. Even after cancellation, the system you grew stays in your hands.
Fast beats perfect
Your business moves in two weeks.
You do not need to wait for a perfect blueprint. Start small with core features and grow the system while generating revenue.
From vendor to team
Your dedicated engineering department.
We are more than a vendor. We share your daily challenges and keep improving the system like your in-house team.
Every touchpoint, within a flat rate.
From headquarters web admin systems to on-site smartphone apps, one team builds everything your business needs end to end.

Not theory. Proven delivery.
From complex operations systems to consumer apps, Finite Field builds systems that drive business results.
Global order management system
A robust backbone for cross-border commerce. Centralize everything from English UI to document output and chat.
International transactions were managed via email and spreadsheets, creating complexity. Language barriers, time differences, and the workload of creating quotes, invoices, and packing lists became major bottlenecks.
We built a member-based ordering system. From catalog browsing to quote requests, orders, and PDF document output, everything is handled on the web. Every screen supports English to deliver a stress-free UI for overseas buyers.
Home-visit nursing matching system
See availability instantly. Real-time sales support that stops missed requests.
When external care managers were visiting clients and needed nursing support, they had to call to check availability. Delays meant opportunities were lost to competitors.
We visualized nurse schedules in real time. External care managers received accounts so they could search and confirm available nurses on their phones, enabling matches before placing a call.
Self-serve harvest and unmanned sales app
Pick it yourself, pay on the spot. Harvest experience plus Stripe payments for a fully unmanned farm stand.
Producers wanted direct sales without staffing costs. Consumers did not know what was available until they arrived, leading to frustration and fewer visits.
We built a new model in Flutter (Flutter Web) where consumers harvest and pay on their own phones. They can check available produce before arriving, scan a QR code on-site, harvest, and pay via Stripe immediately.
No heavy specs required.
Just drop requests in chat. You can freely reshuffle priorities anytime.
1. Ticket
Turn requests into tickets
2. Develop
Build in priority order
3. Review
Review and feedback immediately
Simple pricing that eliminates management risk.
Light
Maintenance phase / small internal tool updates
Standard
New build and growth phase / full-scale delivery
Business
Large-scale, rapid delivery / multiple lines
Logical tech choices that power rapid improvement.
Flutter (Web / iOS / Android)
Ship web and apps from one codebase. The source of exceptional productivity.
htmx
We use ultra-lightweight htmx for public pages such as landing pages and blogs.
Go (Golang)
A robust language from Google that handles complex business logic.
Cloud SQL / Firestore
We choose the best fit. Cloud SQL for complex structures, Firestore for real-time needs.

FAQ
Is there a minimum contract term or any commitment?
No. It's a month-to-month contract, so you can continue or pause based on your business needs. For example, you can use it for just three months to build an MVP (minimum viable product).
Who owns the copyright to the system we develop?
All rights belong to your company. Unlike typical SaaS or no-code tools, you own all source code. If you later hire engineers and move development in-house, the handoff is smooth.
We only have a rough idea. Can we still hire you?
Absolutely — we welcome it. You don't need a detailed spec. Share the problems you want to solve and what you want to achieve. We'll turn that into screens and features, and build a working prototype. You can refine the details while using it.
Can we change the scope/specs during development?
Yes. Since it's a flat-rate model, you can change as many times as needed. If the direction changes, there are no additional fees. We simply reprioritize tickets and start on the new specs the next day.
Will the system stop working after cancellation?
No, you can keep using it. You own the rights, so the system won't be shut down after the contract ends. However, support such as server maintenance and bug fixes will end, so we recommend moving to a maintenance plan (e.g., Light) or switching to in-house operations.
What’s the difference from building with no-code tools?
There’s no “scalability ceiling,” and the result remains an asset. No-code is quick to start, but complex features can be hard to implement, and platform constraints can force a rebuild from scratch as your service grows. Finite Field uses general-purpose programming languages (Flutter/Go), so there are no functional limits and even complex, custom logic is possible. Since you own the source code, you can build an independent asset that isn’t tied to a specific tool.
