Brand websites, apps and custom software

I’m Jan Štok. I plan, design and build each project myself, so the person on your first call is the person who ships it.

Selected work

Two systems that made complicated work simpler

Real projects, the decisions behind them and where each result comes from.

Redrawn from the live app with stand-in products; client data hidden.

A Czech technical distributor · Custom software

From Excel and Word to one quoting system

Before

Every quote was put together by hand: supplier price lists in Excel, products copied into Word, margins and the EUR/CZK rate worked out separately, then a PDF by email.

What I built
  • Guided price-list import for any supplier’s format
  • Automatic margin, discount and EUR/CZK conversion
  • Customer and internal PDFs, plus supplier XLSX orders
What changed

Built so a quote takes minutes instead of hours.

About 4,000 products from one supplier import in seconds (my own test).

BKS Hotels · Connected systems

Taking the manual work off a hotel reception

Before

Booking mistakes and phone calls were swamping a small reception.

What I built

I connected online booking to the Previo property system, configured SmartKey room access and upgraded the on-site network.

Previo and SmartKey are third-party systems; I connected and configured them.

What changed

About half as many booking errors (reported by the client).

The hotel no longer needs a full-time receptionist (reported by the client).

Brand websites

Fast, editorial, conversion-minded sites you (or your team) can actually update.

I build brand websites that do your brand justice and still load fast. Custom design, real conversion paths, and a CMS your team owns afterwards. No template look, no agency retainer to change a headline. It’s for companies and small teams who want a site that performs and that they can keep alive themselves. Before I start, you get the scope, a fixed price and the timeline in writing.

You get

  • Custom editorial design
  • Conversion paths that work
  • Next.js, WordPress or Laravel
  • Fast by default

Apps

Focused native iOS apps for small, sharp ideas. Web apps are part of custom software.

I build native iOS apps for focused, single-purpose ideas: the kind that live on your phone, talk to your watch or your health data, and do one thing genuinely well. Swift and the real platform APIs, not a cross-platform wrapper. For founders and small teams who want an app that feels like it belongs on iOS, from the first TestFlight build to the App Store listing.

You get

  • Native Swift
  • HealthKit & device APIs
  • Firebase backend & auth
  • TestFlight to App Store

Custom software

Internal tools and platforms built around how your team actually works.

When a spreadsheet, an inbox, and three browser tabs have quietly become a core process, that’s where I come in. I build the internal tools and web apps a team runs on every day: dashboards, booking flows, quoting systems, the import/export plumbing between the things you already use. It’s for small teams who’ve outgrown the manual workaround but don’t want generic off-the-shelf software dictating how they work.

You get

  • Built to your workflow
  • Dashboards & internal flows
  • Next.js or Laravel + Postgres
  • Imports, exports & integrations

AI integration

Practical AI in your products and workflows: assistants, automation, less busywork.

I build AI into the products and workflows you already run: assistants that answer real questions, automations that handle the repetitive parts, and pipelines that read and sort documents so a person doesn’t have to. This is for teams drowning in the same inbox messages, the same lookups, the same copy-paste, who want the busywork gone rather than a demo that impresses for a week.

You get

  • Assistants grounded in your content
  • Workflow automation
  • Document and data processing
  • Honest scoping first

No public case study for this yet. Bring your use case to the call.

Who’s behind Blik

Jan Štok

Blik is a studio of one: I scope, design and build every project myself, so the person on your first call is the person who ships it. I’ve built hotel websites, a quoting system that replaced a distributor’s Excel and an iOS app for health data, and connected booking and smart locks for an overloaded reception. Whatever I build, you get a written handover, and on new projects the domain, hosting, repository and accounts are in your name from day one.

Three characters, one person. Blink listens, Scribble builds, Spark launches, and all three are me.

LinkedIn (opens in a new tab)

Why one person

  1. You talk to the maker, not an account manager.
  2. Built around your workflow, not a generic template.
  3. Fixed scope and price, agreed up front. No surprise invoices.
  4. You always know exactly where the project stands.
  5. On new projects you own the code, the accounts and the documentation. Nothing is locked in my head.
  6. Made to load fast, convert visitors, and stay easy to maintain.

Questions

How do we start?

A short call or an email describing what you’re building. If we’re a fit, you’ll get a one-page proposal with scope, a fixed price and a timeline within two working days.

Who actually does the work?

I do. I’m Jan Štok. Blik is a studio of one, so the person who scopes your project is the same person who designs and ships it, start to finish.

What do you actually build?

Brand websites, iOS apps, custom internal software, and practical AI built into products and workflows. Four disciplines, one person. I take on the work I can do properly.

What’s the tech stack?

Whatever fits the job: Next.js / React or WordPress for web, Swift for native iOS, Laravel / Supabase for backends. The right tool, not a fixed template.

How long does it take?

Brand websites usually take 3–6 weeks; apps and platforms 6–12. You’ll always know where it stands along the way.

What happens after launch?

Launch isn’t the end. I hand over, train your team and stay available.

You’re one person, so what if you’re unavailable?

Fair question. The answer lies in how the project is set up, not in a promise. On new projects, the domains, hosting and repositories are in your name from day one, and the code and documentation are yours once the final payment is made. I build on mainstream tools, not a private framework, so another competent developer can pick it up. For anything in production we agree a response window in writing before it goes live.

What does it cost?

A fixed price per project, agreed before anything starts. No surprise invoices. Tell me the scope and I’ll send you a proposal.

Start a project

Tell me what you’re building. Within two working days of our call, I’ll send a fixed-price proposal.

What happens after you send it

  1. I read your brief and get back to you.
  2. We go through it on a short call or by email.
  3. If we’re a fit, you get a one-page proposal with scope, a fixed price and a timeline.

Within two working days of our call, I’ll send a fixed-price proposal. All fields are required unless marked optional.

What do you need?
Approximate budget

A rough range excl. VAT is enough. It helps me reply with something realistic.

When do you need it? (optional)

I use your details to reply and to prepare a proposal. The message also notes how you found the site. Privacy

Rather talk it through first?

Google Meet, no obligation.
