FAQ
What types of software do you build and what is your core tech stack?
I build web apps, mobile apps, SaaS platforms, automation systems, and AI-powered tools. My core stack is React and Next.js for web frontends, React Native Expo for cross-platform iOS and Android mobile apps, Node.js and Express.js for backend APIs, and Supabase or Firebase for database and auth
Can you build a full stack SaaS web application with authentication, payments, and a dashboard?
Yes, this is exactly the type of project I specialize in. A typical full stack SaaS build includes a Next.js or React frontend, Supabase backend with PostgreSQL database and row-level security, Supabase Auth or Auth0 for user authentication with role-based access, Stripe for subscription billing.
Do you build mobile apps for both iOS and Android, and can they be published to the App Store and Google Play?
Yes — cross-platform iOS and Android development using React Native Expo is a core part of my services. One codebase covers both platforms, which means you get an iOS app and an Android app at a fraction of the cost of building them separately. I handle the full lifecycle: Expo build configuration
Can you integrate AI features like ChatGPT or Claude into my software application?
Yes. AI integration is one of the fastest-growing parts of my software development work. I integrate OpenAI's GPT-4o and Claude API for conversational AI, content generation, summarization, classification, and data extraction use cases. For more complex AI workflows I use LangChain
Can you build n8n automation workflows and API integrations as part of my software project?
Yes — n8n automation is a service I offer standalone or as part of a larger software build. I build n8n workflows for lead generation pipelines, CRM automation, webhook processing, scheduled data syncing, email sequences, Slack/Teams notifications, Airtable/Google Sheets integrations
How fast can you deliver a working software application and what does your development process look like?
Simple modules and MVPs ship in 5–7 days. Full web or mobile apps with backend and payment integration take 10–14 days. Large SaaS platforms or full-stack products with AI, automation, and multiple user roles take 21–30 days. My process is straightforward: I review your requirements on day one
Do you provide the full source code and documentation after the software project is complete?
Always. Every software project I deliver includes the complete source code via a private GitHub repository, a README with setup instructions, environment variable documentation, and deployment guides for whichever hosting platform the project uses. For larger projects I also provide architecture doc
Can you build a React Native app that connects to Supabase with real-time features and offline support?
Yes — React Native with Supabase is one of my most-used stacks. Supabase's real-time subscriptions work natively with React Native, meaning your app UI updates instantly when data changes in the database — perfect for chat apps, dashboards, collaborative tools, and live feeds. For offline support
What is the difference between your MVP, Product, and Scale packages for software development?
For offline support I use a local cache layer with WatermelonDB or AsyncStorage synced against Supabase, so the app works without a connection and syncs automatically when it comes back online. Authentication is handled via Supabase Auth with support for email/password, Google, Apple, and phone OTP
Do you work on existing codebases or only build software projects from scratch?
Both. I work on greenfield projects built from scratch and on existing codebases that need new features, bug fixes, refactoring, or third-party integrations. If you have an existing React, Next.js, React Native, or Node.js project, send me the GitHub repo and describe what you need. I'll review the
