Why us
Years of building complex systems: payments, integrations, backend and cloud infrastructure.
Routine work moves faster, leaving more time for architecture, testing and quality.
Decisions and responsibility for the code stay with senior engineers.
Complex domains
Our engineers have worked on MedTech and food-tech products, where reliability and careful data handling matter more than speed of demo.
A product we built ourselves
Livenout is an events platform we designed and have been building since mid-2025: Next.js, Spring Boot, PostgreSQL, Stripe, vector search, cloud deployment.
Senior people, no layers
You talk directly to the engineers doing the work. Frontend, backend, DevOps, QA and analysis in one team.
What we do
Complex tasks, end to end or as a senior addition to your team.
Web platforms and SaaS
From idea to a working platform: auth, roles, data model, admin, backend, deployment.
Learn moreAI-powered search
Semantic search and RAG over your own content: embeddings, vector search, answers grounded in your data.
Learn morePayments with Stripe
Checkout, card pre-authorization, saved cards, webhooks.
Learn moreCloud and DevOps
Environments, deployment, databases and monitoring that you can rely on.

Livenout is an events platform we designed and built end to end: aggregator, search, payments and cloud deployment.
How we work
- 01
Call
30 minutes to understand the problem, the users and what has to be true for the product to work.
- 02
Written estimate
Scope, what is deliberately left out, timeline and price, in writing, before any work starts.
- 03
Short iterations
Working builds on a preview URL, so you see the product grow instead of waiting for a big reveal.
- 04
Handover
Code in your repository, deployment on your accounts, short documentation. No lock-in.
Pricing
We do not publish a rate card: the scope of complex work varies too much. After the call you get a written estimate. For a defined scope it is a fixed price; for ongoing work it is hourly or monthly. If the budget is limited, tell us upfront and we will cut the scope, not the quality.
Questions you probably have
Who is on the team?
A senior team: two frontend engineers, two backend engineers, DevOps, QA and a business analyst. We staff each project with the people it needs and list them in the estimate. We can start from zero, take over what you have and help you get to release.
What kind of tasks do you take?
Complex ones: platforms with several user roles, third-party integrations, payments with non-trivial logic (pre-authorisation, saved cards, recurring charges), search over large data sets and reliable cloud infrastructure. If a task is not for us, we say so on the first call.
Can you take over existing code?
Often yes, after a short review of the repository. We will tell you honestly if a rewrite would be cheaper than a rescue.
Which stack do you use?
Our base is Next.js and TypeScript on the frontend, Java with Spring Boot, Python and Node.js (NestJS) on the backend, PostgreSQL, Stripe, DigitalOcean and Vercel. We are not tied to it, though: we work in whatever stack your product runs on.
