Apps and web solutions built for your business.

I build mobile apps, web apps, websites, and webshops — personally, from idea to production.

Why Me

No agency. No markup. No excuses.

Most competitors hide behind a company name so you never know who's actually writing your code. I don't — you already know exactly who you're working with, and that changes everything else too.

You know exactly who's coding your app.

Not a rotating team of unnamed developers behind a company name — you work directly with me, publicly, by name. Every line of code and every decision is mine to own.

No VAT. 25% cheaper before we even talk price.

As an independent developer under the VAT threshold, I don't charge VAT — a straight 25% you don't pay compared to most agencies, before rates even come into it.

No management layers to pay for.

No project managers, no account managers, no markup for people who never touch your code. You pay for development, because that's the only thing happening here.

One developer. One result.

No hand-offs to juniors, no diluted accountability. I build it, I ship it, and I stand behind it after launch.

AI in your product

AI integrations, assistants and agents

I integrate AI into websites, mobile and web apps, and existing business systems. From a chatbot that answers questions to an agent that performs specific tasks — built around real user needs.

Discuss an AI integration

  • AI assistants and chatbots

    Conversational assistants for questions about services, products, or documentation — like the AI assistant on this website.

  • AI agents and automation

    Agents connected to tools and APIs that carry out agreed tasks, with defined permissions and user confirmation where needed.

  • AI in existing applications

    Content search, document summaries, and assistance with everyday work, connected to your product's data and features.

Your own digital product

Have an idea you want to offer to users?

I build web and mobile products you can monetise through one-off purchases, subscription plans, or usage-based billing. It can be a SaaS platform, a mobile app with subscriptions, or an entirely new service built around your idea.

  • User accounts and roles
  • Subscriptions and plans
  • Online payments
  • Administration system
  • Web, iOS, and Android
  1. 01

    Scope and priorities

    Clarify the users, the problem, and the features that belong in the first release.

  2. 02

    MVP and development

    Build an initial version of your product with room for future improvements.

  3. 03

    Launch and further development

    Prepare for production and improve the product around real user needs.

Discuss your product

An existing project

Have an app that needs finishing or fixing?

You don't always need to start over. As an independent developer, I take over existing mobile and web apps: review the code, identify problems, and recommend what to keep, fix, or improve.

  • Code review and technical audit

    Review code quality, architecture, and technical risks, with practical recommendations for your next step.

  • Project rescue and takeover

    Continue development after a previous developer and finish an incomplete application.

  • Bug fixes and stabilisation

    Resolve crashes, bugs, and unreliable features in an existing product.

  • Refactoring and upgrades

    Clean up an existing codebase, update dependencies, and prepare it for further development.

  • Performance optimisation

    Improve loading times, reduce unnecessary rendering, and make the app more responsive.

About

Senior developer, no surprises.

I'm Matko Milić, a software developer from Croatia specialising in React Native and React. I hold a Bachelor's degree in Computer Engineering and have been building production apps since 2021.

Unlike agencies that pass your project between juniors, I work directly with you — on every line of code, every decision, from kickoff to launch. You always know who is responsible for your product.
