I build end-to-end web and mobile products — from server infrastructure and APIs to pixel-perfect interfaces. Specializing in Next.js, React Native, AI integrations and blockchain.
I deliver full-cycle development: backend architecture, frontend interfaces, mobile apps, DevOps and third-party integrations. Every project ships with clean code and production-grade reliability.
Building responsive, high-performance web interfaces with React and Next.js. SSR, SSG, ISR — choosing the right rendering strategy for each use case.
Designing RESTful and GraphQL APIs, database architecture, authentication flows and server-side logic with Node.js and PostgreSQL.
Cross-platform iOS and Android apps with React Native and Expo. Offline-first architecture, push notifications and native module integration.
Smart contract development with Solidity, wallet integration, on-chain data indexing and DeFi protocol interfaces.
LLM-powered applications, Telegram/Discord bots with conversational AI, RAG pipelines and function calling for task automation.
Full SaaS architecture: multi-tenant systems, Stripe billing, role-based access, admin dashboards and analytics from day one.
Real-time Web3 dashboard with on-chain data visualization, wallet connection (MetaMask, WalletConnect) and smart contract interaction layer.
Multi-tenant SaaS platform with GPT-powered content generation, usage-based billing via Stripe and a team collaboration workspace.
Cross-platform mobile app with offline-first architecture, background sync, push notifications and real-time data via WebSockets.
Comparing architecture, performance and DX of both approaches. Server Components, App Router and when vanilla React is still the better choice.
