Your app idea deserves
to become reality.
From complex ordering systems to AI-powered mobile solutions — I build apps that generate revenue, automate operations, and scale with your business. 18+ years of development experience. 50+ shipped projects.
Sounds familiar?
Your agency quoted $80K+ and 12 months
Traditional agencies love padding timelines and budgets. They assign junior devs to your project while charging senior rates. You end up overpaying for an underwhelming MVP that needs another round of investment.
Your customers are stuck on a desktop-only workflow
Orders come in via phone calls. Delivery drivers rely on paper slips. Your team juggles spreadsheets. Meanwhile, your competitors have sleek mobile apps that automate everything and keep customers coming back.
You hired freelancers who disappeared mid-project
The cheapest bid on Upwork delivered buggy code, missed deadlines, and ghosted you after getting paid. Now you have a half-built app, spaghetti codebase, and no one to maintain it. Starting over feels impossible.
The real cost of mobile app development
- 6-18 months delivery
- Junior developers doing the work
- Separate iOS and Android teams
- $5,000+/month maintenance
- Limited direct communication
- Vendor lock-in to their stack
- 4-12 weeks delivery
- 18+ years senior experience — me, personally
- One codebase, both platforms (React Native)
- Affordable maintenance packages
- Direct WhatsApp/Slack communication
- Full code ownership — no lock-in
Apps I've shipped
Real projects. Real businesses. Real revenue generated.
Pizza Sidonio

What I build
Every app is tailored to your business. Here is what you get.
How we work together
Discovery Call
We discuss your idea, target users, budget, and timeline. I assess feasibility and suggest the optimal tech stack. Free, no obligation.
Design + Prototype
I create wireframes, UI mockups, and an interactive prototype. You see and feel the app before a single line of production code is written.
Agile Development
Weekly updates. You see progress every milestone, provide feedback, and course-correct early. No surprises at the finish line.
Launch + Support
App store publishing, deployment, monitoring. Ongoing maintenance to keep your app fast, secure, and up to date. I do not disappear after launch.
What clients say
Michal delivered our entire ordering ecosystem — customer app, driver app, and POS integration — ahead of schedule. The auto-SMS feature alone saved us hours of manual work every day.
We needed someone who could handle both the React Native mobile app and the Firebase backend. Michal did it all — and the TypeScript migration was seamless. A true full-stack mobile developer.
Our construction management app needed to work offline on job sites. Michal built a robust offline-first architecture that syncs perfectly when connectivity returns. The React Native app runs beautifully on both platforms.
Frequently asked questions
I primarily work with React Native for cross-platform apps (iOS and Android from one codebase) and Progressive Web Apps (PWA) for lightweight mobile solutions. For backend, I use Node.js, Python, and Firebase. The tech stack is always chosen based on the project's specific needs.
A simple app typically takes 4-8 weeks. A complex system like an ordering platform with POS integration, delivery tracking, and automated SMS takes 3-6 months. I provide detailed timelines after the initial consultation.
Yes. Using React Native, I build apps that run natively on both iOS and Android from a single codebase. This saves you 40-60% in development costs compared to building two separate native apps.
Absolutely. I specialize in system integrations — POS systems, CRMs, payment gateways, SMS providers, telephony APIs, and more. For example, I built a complete ordering system for Pizza Sidonio integrated with the Varyshop POS across 5 locations.
A native app (built with React Native) is installed from the App Store or Google Play and has full access to device features like GPS, camera, push notifications, and offline storage. A PWA runs in the browser but looks and feels like a native app — no app store needed. PWAs are faster to build and deploy, while native apps offer richer functionality. I help you choose the right approach based on your requirements.
Yes. I offer monthly maintenance packages covering updates, bug fixes, performance monitoring, app store management, and feature additions. Your app stays current and competitive.
I handle the entire publishing process — Apple App Store, Google Play Store, and web deployment for PWAs. This includes screenshots, descriptions, compliance, and ongoing updates.
Simple apps start from $15,000. Complex multi-app ecosystems (like the Pizza Sidonio project with ordering, delivery, and POS integration) range from $30,000 to $60,000. Every project gets a detailed quote after the free consultation — no hidden fees, no surprises.
