React | NextJs | Typescript | NodeJs | Full Stack Developer
I'm a web developer with 3+ years of experience building and maintaining web applications, including working on long term projects with clients. I specialize in React and Next.js, with experience across the stack using Node.js, Express, PostgreSQL, and MongoDB. I work on both new features and existing applications, from frontend development and API integrations to database-backed functionality. I'm comfortable joining an established project, understanding its codebase, and working within an existing development workflow. My tech stack includes: Frontend: React, Next.js, JavaScript, TypeScript, Redux, Vite Data Fetching & State Management: TanStack Query (React Query), Redux UI & Styling: Tailwind CSS, Material UI (MUI), Shadcn UI, HTML, CSS Backend: Node.js, Express, REST APIs Databases: PostgreSQL, Neon, MongoDB Authentication & Deployment: Auth0, Vercel, Render Tools: Git, GitHub, GitLab, Bitbucket, Figma AI Tools: Claude, AI-assisted development I value clear communication, independent work, and writing maintainable code that fits the existing project. I take a practical approach to solving problems and aim to deliver solutions that meet the project's requirements without overcomplicating things. I've worked with clients on ongoing projects and understand the importance of being reliable, adapting to existing workflows, and communicating clearly throughout development. If you need help building a new feature, integrating an AI powered functionality, improving an existing application, fixing bugs, or contributing to a project already in progress, feel free to reach out. I'd be happy to discuss what you're working on.
