Senior Full Stack Developer | React, Node.js & AI Integrations

I’m a Senior Full-Stack Developer with 10+ years of experience building web and mobile products in the JavaScript and TypeScript ecosystem. My core technologies are React, Next.js, React Native, and Node.js, and I work confidently across both frontend and backend development. I turn product ideas and business requirements into working software end to end. I can take an application from Figma designs to a deployed production system, covering the complete development cycle: UI implementation, frontend logic, backend services, APIs, databases, testing, infrastructure, and CI/CD. Alongside hands-on development, I can take responsibility for architecture, technical decisions, task planning, code reviews, and delivery. I focus on practical solutions, maintainable code, and getting working features into production. I also implement AI-powered features and integrations with modern AI APIs and use AI-assisted development workflows to deliver faster without compromising production quality. 💻 Frontend: JavaScript, TypeScript, React, Next.js, React Native, Redux Toolkit, Zustand, TanStack Query, Tailwind CSS, Material UI, shadcn/ui, Storybook, Cypress, Vitest, Jest ⚙️ Backend: Node.js, Express, Fastify, NestJS, REST APIs, GraphQL, WebSockets, PostgreSQL, MySQL, MongoDB, Redis, Supabase, Prisma, Drizzle ORM, AWS, Azure, Docker, CI/CD, Sentry, Datadog, Grafana 🔌 Integrations: OpenAI API and AI integrations, Twilio, WebRTC, SMS, WhatsApp, Pusher, Ably, Mapbox, Google Maps, third-party APIs
