How I can help

We can start anywhere – with a first idea or a finished app. And I think about security from the start.

  • Work it out

    I help you clarify whether a digital product makes sense, and which one.

    • Assessing the idea and goals
    • Market and competitor research
    • Scope of the first version (MVP)
  • Build

    I design and develop a mobile app, website or whole system – as a first version or straight away as a finished product.

    • UX and UI design
    • iOS and Android in Flutter or native
    • Backend, admin and integrations with your systems
  • Secure

    I review the security of your app – even if someone else or an AI built it – and fix what I find.

    • Code, server and setup review
    • Apps built with AI
    • Secure AI features and agents
    More about app security
  • Grow

    After launch I look after the product and keep developing it based on how people actually use it.

    • Maintenance, updates and fixes
    • Further versions driven by data and feedback
    • From MVP to a complete product

Security from the first line

Apps are built faster than ever, often with AI – and speed brings more vulnerabilities. I review your app and fix what I find straight away.

How a review works
  • Access to data

    Does every user see only what they should?

  • Keys and passwords

    Have access keys or passwords leaked into the app or the code?

  • Server and communication

    Is the server set up properly and the communication with devices secure?

  • AI features and agents

    Can the AI in your app be abused?

How I work

Every project is different, so I don't have one fixed process. First I listen, then I tell you honestly what I think and suggest the next step.

Free introductory consultation

60–90 minutes in person or online. We talk through what you're dealing with and you leave with a proposed next step – no obligation.

  • Understand first, then build

    I ask about the goal, not just features. Sometimes the best advice is not to build yet.

  • Security from the start

    I think about security from the first design, not after launch.

  • Open and fair

    We agree scope and price up front, and after each part you can decide again.

Jakub Smolík

One person. A team of AI agents.

My name is Jakub Smolík, and for more than six years I have been designing and developing apps – for banks, the public sector, large companies and startups. On the projects I lead, I'm responsible for the whole solution, from design and development to security.

Technology is a tool for me, not the goal – what interests me is what the product will bring you. I like looking after a whole product best, from the idea to running it. I'm based in Prague and happy to come to a meeting.

How I work with AI agents

A team of AI agents helps me with research, drafts, coding and testing. That lets me do the work of a small team – faster and without agency overhead. Decisions and responsibility for the result stay with me.

Sensitive data and know-how I process only with local models on my own secured computer. Hence the name smolikja team – me and my team of AI agents.

What you can count on

  • The product is yours

    The code, the App Store and Google Play accounts and the servers belong to you.

  • Someone else can pick it up

    I use mainstream technologies and document every project carefully.

  • Schedules with a buffer

    I plan with room for the unexpected, so you always know where things stand.
