Full-cycle product partner — not just server first aid

Sound familiar?

The hidden cost of a fragile system

Most businesses don't need more features — they need the software they already have to stop letting them down. If any of these hit home, we should talk.

Your site goes down and nobody picks up

Every hour of downtime is lost revenue and lost trust. You need someone who answers — fast.

You've outgrown your current setup

The thing that got you here is now slow, brittle, and scary to change. Scaling shouldn't mean starting over.

Manual work is eating your team alive

Reports, data entry, repetitive tasks — hours every week that automation and AI could quietly hand back to you.

You inherited code nobody understands

A previous dev disappeared, docs don't exist, and every change is a gamble. We stabilize it and take the wheel.

We fix all of that — then build whatever comes next.

Product development

We build complete products, not just static websites

Whether you need a new product from scratch, a mobile app, a business dashboard, an AI-powered workflow, or a legacy system rebuilt, LIENOU handles the full cycle — planning, development, deployment, and long-term maintenance.

New project or existing system — we can plan, build, launch, and maintain it.

Frequently asked questions

What do you need for a first conversation?+

For the first conversation, we only need a short explanation of what you want to build, fix, improve, or automate. If you already have a website, app, server, document, design, or existing system, you can share the link, screenshots, access details, or a short description of the current problem. You do not need to prepare a full technical specification — we help you clarify the scope, risks, timeline, and next steps after the first review.

Can you build a product from scratch?+

Yes. We can help you build a new digital product from the first idea to production. This includes planning, UI structure, frontend development, backend APIs, database design, authentication, payment integration, admin dashboards, deployment, and long-term maintenance. We can also start with an MVP first, then improve the product based on real users and business needs.

Do you build mobile apps?+

Yes. We build mobile applications for iOS and Android, including MVPs, customer apps, internal business apps, booking apps, ecommerce apps, and apps connected to existing backend systems. Depending on the project, we use cross-platform technologies such as React Native or Flutter to reduce cost and speed up delivery. We also handle API integration, authentication, push notifications, payment flows, and app deployment support.

Can you add AI features to an existing business?+

Yes. We can integrate AI into existing websites, apps, workflows, and internal systems. Common use cases include AI chatbots, custom AI assistants, OCR document processing, automated reports, customer support automation, content generation workflows, and business process automation. We focus on practical AI features that reduce manual work or improve operations — not vague AI hype that sounds impressive and does absolutely nothing.

Do you offer emergency support?+

Yes. We provide urgent technical support for websites, applications, servers, deployments, bugs, downtime, performance issues, and production incidents. For maintenance clients, urgent issues are handled with a priority response window, typically within 2–4 hours depending on the agreed support plan. For new clients, we can still review the issue first and let you know if we can safely help without risking your current system.

How much does a project cost?+

The cost depends on the scope, complexity, timeline, integrations, and level of long-term support required. A simple website or landing page costs less than a full web application, mobile app, backend system, AI workflow, or infrastructure migration. After the first conversation, we provide a clear estimate with the recommended scope, timeline, deliverables, and maintenance options — no hidden fees, no vague technical fog machine.
