You will get A scalable web application with AI features, backend, and deployment ready
Project details
I build complete web applications from scratch, handling both frontend and backend with a focus on real functionality, not just visuals. My work is centered on delivering usable products: systems that manage data, automate processes, and solve concrete business problems.
I typically work with Next.js for the frontend and architecture, combined with Supabase (including self-hosted setups) or custom backends for database, authentication, and logic. I also integrate AI capabilities when needed; chat systems, assistants, or automated workflows using APIs like OpenAI or Anthropic.
Clean and structured UI that is easy to use
Backend logic and database designed for scalability
API integrations and external services when required
Deployment to VPS or AWS environments, ready for production
I approach each project from a product perspective. That means understanding the goal first (automation, conversion, internal tool, SaaS, etc.) and then building only what is necessary to make it work efficiently, without overengineering.
Each project is built based on the specific use case, ensuring performance, maintainability, and the ability to scale or extend in the future.
