FAQ
Which tech stack do you use for development?
I build high-performance ecosystems using a modern stack: Vue.js (Composition API) for the web frontend, Python (Flask/FastAPI) for the AI-powered backend, and Flutter for native iOS and Android apps. This ensures a single, scalable codebase with native performance.
Can you integrate AI features into my existing app?
Yes! I can integrate LLMs, custom AI agents, and automated data processing into new or existing projects. Whether it's a chatbot, smart analytics, or content generation, I’ll ensure the AI is seamlessly connected to your UI and backend.
Will my app work on both iOS and Android?
Absolutely.I develop a single codebase that compiles into truly native apps for both Apple and Google stores. This saves you significant development time and budget while maintaining 60FPS performance and a consistent look across all devices.
How do you handle large data and image hosting?
For performance and scalability, I don't store large files directly in the database. I implement industry-standard AWS S3 buckets for media storage and use PostgreSQL or MongoDB for structured data. This ensures your app stays fast even with thousands of users.
Do you handle the App Store and Play Store submission?
I offer submission support as a Gig Extra (included in the Premium tier). I will guide you through the technical requirements, generate the necessary build files, and help manage the review process to ensure your app goes live successfully.
Who owns the source code once the project is finished?
You do. Upon completion and 100% payment, the full ownership and intellectual property of the source code are transferred to you. I provide well-documented code via a private GitHub repository so your team can maintain it easily in the future.
Do you provide post-deployment support?
Yes! I provide 14 days of complimentary technical support after your app goes live to ensure everything is running smoothly. For long-term peace of mind, I also offer extended maintenance packages that cover security updates, OS compatibility checks for iOS/Android, and performance monitoring.
How do you handle future updates or feature requests?
build all applications with a modular, scalable architecture so that adding new features in the future is easy and cost-effective. If you need a new feature later, we can simply open a new project. I provide full documentation so any developer—including myself—can pick up right where we left off.
