Rapid Build
From idea to working product — in weeks, not months.
Build something real, fast
Most software projects take too long before anything works. Discovery phases stretch into months, architectural debates delay the first line of code, and by the time a prototype exists, the original idea has been forgotten or the market has moved on.
Lothringer offers a different model: a focused, time-boxed engagement that takes your idea from a brief conversation to a working, deployed product — typically in two to six weeks. Not a wireframe. Not a slide deck. A real, running application you can put in front of users, investors or clients.
This is made possible by combining 25+ years of engineering and delivery experience with modern AI-assisted development tooling. The result is a dramatic compression of the time between idea and outcome — without cutting corners on quality, security or architecture.
What we can build
- Native mobile apps (Android, iOS)
- Web platforms and SaaS products
- Customer-facing portals and dashboards
- Internal tools and admin systems
- Business websites with CMS or booking integration
- AI-integrated applications and workflows
- Expense tracking, scheduling and operational tools
How it works
1 Scope
We start with a focused conversation — typically half a day — to understand your idea, the problem it solves, who it is for, and what "done" looks like. We define a realistic MVP scope: the smallest version of the product that delivers genuine value and can be demonstrated to real users.
Deliverable: written scope, tech stack recommendation, timeline and cost estimate.
2 Build
Rapid, iterative development using modern stacks — Node.js, Flutter, React, Python — augmented by AI tooling to accelerate the mechanics of building. You receive frequent updates and can see the product evolving in real time. No big-bang deliveries, no surprises.
Deliverable: working application, source code, basic documentation.
3 Deploy
The product is deployed to a production environment — cloud-hosted, properly configured, with a domain, SSL and basic monitoring in place. You end the engagement with something live that real people can use, not a local demo that lives on a developer's laptop.
Deliverable: live deployed application, hosting handover, post-launch support options.
AI-augmented delivery — what it means in practice
Every project Lothringer delivers uses Claude AI as an active part of the development workflow. This is not about replacing engineering judgement — it is about eliminating the slow parts: generating boilerplate, writing and reviewing tests, drafting documentation, catching issues early in code review, and exploring architecture options rapidly.
The engineer remains responsible for every design decision, every architectural trade-off, and every line of code that goes to production. AI makes the execution faster; experience makes it right.
The difference in practice: a project that would typically take three months of traditional development can be scoped, built and deployed in three to six weeks. The quality bar does not change — the timeline does.
Real examples
The in-house products below were all built using the same rapid build approach — each taken from initial concept to a live, deployed product. They serve as working demonstrations of what is possible and at what speed.

List Manager
Native Android app — Flutter, SQLite, offline-first, typeahead suggestions. Built for Google Play.
Engagement models
Rapid Build engagements are scoped and priced per project rather than on a day rate, so you know exactly what you are getting and what it will cost before work begins. Typical engagements run from two to six weeks depending on scope.
- MVP Sprint — a tightly scoped prototype or proof of concept, typically two weeks. Ideal for validating an idea before committing to a full build.
- Full Rapid Build — a complete, production-ready product built and deployed end-to-end. Typically four to six weeks for a well-scoped web or mobile application.
- Prototype + Handover — we build the MVP and then hand over to your internal team with documentation, architecture notes and a structured knowledge transfer session.
- Ongoing iteration — post-launch feature development on a rolling monthly basis, with a fixed scope agreed at the start of each month.
All engagements include a free scoping conversation. No obligation to proceed.
