Mobile App Development Expert 🚀 3M+ Downloads across all apps I've built 🏆 6+ years providing flutter mobile app development services 🥇 Top-3% on Upwork Worldwide
🌟 The founders I work with are launching killer apps. I build them:
● "Update went successful - our Monthly Active Users crossed 35k"
● “1M downloads reached. Let's plan the next release”
● "We've worked with a lot of sub-contractors. Your process is just at another level"
Founders that work with me can sleep well at night: I, as a full stack developer, take on ALL risk with my guarantee package.
⚡︎I cannot help everybody, but we may be a great fit if you are thinking:
● "I don't want to pay first and get a laggy ios flutter app after"
● "I'm new to tech and I need a detailed roadmap"
● "I'm NOT a developer, and I don't have time to test and manage the app!"
● "I've hired a flutter developer before, and the product launch was embarrassing - I don't want that EVER again"
● "I need a flutter app developer I KNOW 100% will understand my product RIGHT"
I focus on Mobile App Development - from idea to launch. I can also accept your designs or wireframes.
🥇COMPANIES I WORKED WITH IN 2025:
kidnation com
comitas com
crossroads-gmbh ch
stanserhorn ch/en
buyrocks de/en
switch5sport com
crewksa com
Working with me, you will
★ Get clear roadmap - I handle the Planning, Wireframing, Designs, Development, Testing & App Publishing
★ Receive "concierge", white-glove support 24/7 personally from me
★ Focus on other aspects of your business (or even your current job) while I handle ios mobile app development. You won't spend more than 1hr/wk managing the project
★ Get clean, well-documented, future-proof codebase
★ Overview project status anytime - I'll send access to code and project management tool from day one
...and even save money thanks to my pre-built components of the app that speed up flutter mobile app development by up to 50%!
My clients have a LOT to say about me:
✅ Smooth work, we loved working with Roman and his Team! - Founder that did $1.5M+ in Pre-Sales of his physical device, powered by our software.
✅ Your project management process is better than literally any other team we've ever worked with. You've nailed that 3d character rendering - Product Development Company CEO after MedTech app launch
✅ Can I say that they exceed my expectations when they continue doing it release after release? - Streaming Service Founder who got 35k+ Monthly Active Users
✅ You've provided the best web developer I could ask for! I want to be your Middle East sales partner - Startup Founder that raised $300k
Not every business is my client, though. Some signs we might not be a good fit include:
✗ Data-Driven Approach is not for you. You like to take BIG RISKS not backed up by Product Research - can't build a reliable product this way, especially if it is related to ios neo banking.
✗ You don't want a Custom-Tailored Product. You just want a cheap & generic Mobile App - vibe-coding is not about me. I provide high-quality mobile app development services and charge accordingly.
I've been building flutter and react native apps for others for 6+ years. I've also bought & sold apps, and launched my own products - so I got a 360 view on the whole industry. I know what it takes to make a killer app that generates stable MRR.
🔢 My stats:
● Top-3% Globally on Upwork
● 3M+ Downloads: Streaming, Fitness, Ecommerce, Fintech, Medtech, ...
● Personally released at least 1 app each month in 2024
● Over 20 Founders successfully launched with me (not including my own apps)
● Over 30 apps built from scratch, created modular system to leverage this experience
🚀 About my company eclipt ai:
INTEGRITY IN EXCELLENCE above all things: Excellent work, on time, every time. We only take on mobile app development projects we are certain we can knock out of the park.
We provide the following services: mobile app development, flutter mobile app development, ios mobile app development, react native developer services, php developer services, react development.
Our time is LIMITED: We work fast, but we have highly personalized customer support. I (or my 50/50 partner) personally communicate with every single client. We can't build more than 8 successful apps per year, so we have to choose new clients carefully. (This is not a sales tactic. It is reality.)
What we look for in a new client:
● Open mind, relaxed attitude
● Values integrity & relationships
● Focused on delivering value to end-user
● Knows our minimum scope, and wants the BEST
