Engineering & Platforms

For when you need more than a website. We build the platforms, tools, and integrations that carry heavier work: online stores, web apps, custom systems, and the data behind them, engineered to be robust, secure, and ready to scale.

Platforms, web apps & integrations

When a website is not enough

Sometimes the job is bigger than a site: a store, a web app, a platform that holds real data and real traffic. Most companies solve it by hiring one firm for the brand and another for the build, then spend the project getting the two to agree.

We keep both in one place, so the engineering and the brand hold together.

The work speaks first

From scaling software companies to investment platforms, builds made to be robust and ready to grow.

How we build a platform

From a hard problem to a platform that scales

  1. Frame

    We map what the platform has to do and how it should be built: the requirements, the architecture, and the technical direction.

    • Discovery
    • Requirements
    • Technical architecture
    • Integrations mapping
    • Stack and approach

  2. Make

    We engineer the platform itself: the product, the integrations, and the data behind them, built to hold up under real use.

    • Front-end and back-end engineering
    • Web apps and custom systems
    • E-commerce
    • Integrations and APIs
    • Data and infrastructure
    • QA and security testing

  3. Launch

    We launch the platform with care and make sure it is secure, reliable, and ready for real traffic from the start.

    • Deployment
    • Security and performance
    • Monitoring
    • Documentation and handover

  4. Evolve

    Platforms grow and change. If you want, we stay on to maintain, improve, and scale it as you grow.

    • Maintenance and support
    • New features
    • Scaling and optimization
    • New integrations

Testimonials

What leaders say about working with Lavva

  • Sérgio Ferreira

    Brand Manager, Critical Software

    We’ve been working with Lavva for eight years. In that time, they’ve helped shape our brand and visual identity and built seven websites across our companies. Today, we see them as true partners.

  • Hermann Koch

    Founding Partner, EquityPitcher Ventures

    My experience with web agencies has always been that anything is possible and no problem during the acquisition phase, but unfortunately this was often no longer the case during execution.

    The collaboration with Lavva was therefore extremely refreshing. The Lavva team really got to grips with our identity and business model and was always one step ahead of us in terms of ideas and implementation.

    The whole process was smooth and super pleasant, always with a solution-oriented mindset and a great result. Many thanks to Lavva!

  • João Francisco Silva

    Commercial Director, Vinha Boutique Hotel

    The result was phenomenal. Today the journey starts once the client enters our website, far from stepping into the hotel yet.

    A sensorial experience which reveals our four journeys, visually attractive, stimulating and disruptive.

FAQs

Answers to common questions

Quickly find the information you need about us.

  • What can you build beyond a website?

    Web apps, custom platforms, online stores, integrations, and the data behind them.

  • What stack do you build on?

    Next.js, React, PHP, and HTML, with the architecture, integrations, and data engineered around what the platform has to do. For content and publishing, Svalla CMS or WordPress.

  • Is it secure and built to scale?

    Yes. We engineer for robustness, security, and growth from the start.

  • Do you handle the brand too, or just the build?

    Both, with one team, so the platform and the brand stay consistent.

What usually comes next

A platform still needs a brand

The best builds carry a brand and a website people actually want to use. If those are still open, look here next.
