MOBILE APP EXPERT | 30+ APPS DELIVERED | iOS & ANDROID | FLUTTER | REACT NATIVE

Hi! I’m Kate, a Mobile App Expert and Founder of AcidSoft, a mobile development company focused on building and growing real digital products.

I’ve been involved in delivering 30+ mobile applications across different industries - from MVPs and startups to production-ready business applications. I focus not only on writing code, but on understanding the product, user flow, business goals, and what it takes to make an app actually useful for its users.

What I can help you with:

• iOS & Android app development
• Flutter & React Native
• Native Swift & Kotlin
• UI/UX design and implementation
• Backend & API development
• QA & testing
• App Store / Google Play publishing
• ASO and app growth
• Product architecture and technical consulting

Our technology stack:

Mobile: Flutter, React Native, Swift, Kotlin
Backend: Node.js, Java, Spring Boot
Frontend: React, JavaScript, TypeScript
Databases: PostgreSQL, MySQL, Firebase
Maps & Location: Mapbox, Google Maps, GPS & real-time tracking
AI: OpenAI, Gemini, RAG, AI-powered features
Cloud & Tools: AWS, REST APIs, Git, CI/CD

I have experience building applications where performance, scalability, GPS/location features, APIs, real-time data, payments, AI, and complex business logic are important.

I also understand that building an app is only part of the job. A successful product needs good UX, reliable technology, the right architecture, and a clear path to acquiring users.

That’s why my team can cover the full product development cycle - from idea and UI/UX to development, QA, release, and growth.

If you’re looking for someone who can think beyond the code and help turn your idea into a real mobile product, I’d be happy to discuss it.
