TypeScript Developer
on Upwork

I offer full-spectrum TypeScript development: building SPAs with React and Next.js, creating REST and GraphQL APIs with Node.js and Express, database design with PostgreSQL and MongoDB, real-time applications with WebSockets, cloud deployments on Vercel and Cloudflare, and migration of legacy JavaScript codebases to TypeScript.

I enforce strict TypeScript configuration with noImplicitAny and strictNullChecks, use ESLint and Prettier for consistent code style, write unit and integration tests with Jest and Vitest, perform thorough code reviews, and maintain clear documentation. Every project follows SOLID principles and clean architecture patterns.

Yes, I have extensive experience building production applications with React and Next.js. I work with hooks, context API, server components, server-side rendering, static site generation, API routes, middleware, and incremental static regeneration. I also integrate with popular UI libraries like Tailwind CSS and shadcn/ui.

Absolutely. I develop end-to-end TypeScript applications spanning frontend, backend, and database layers. On the backend I use Node.js with Express, Fastify, or NestJS. I build RESTful and GraphQL APIs, handle authentication with JWT and OAuth, integrate with SQL and NoSQL databases, and deploy to cloud platforms.

I follow a phased approach: first rename files to .ts/.tsx and enable strict mode gradually, then add type definitions for external dependencies, refactor critical modules with proper interfaces and types, remove implicit any declarations, and finally enable full strict mode. Each phase includes testing to ensure no regressions.

I have strong experience building scalable backend systems with Node.js and TypeScript. I work with Express, Fastify, and NestJS frameworks, design RESTful and GraphQL APIs, implement authentication and authorization, handle file uploads, integrate with third-party services, and optimize performance with caching and database indexing.

I maintain clear and proactive communication through Upwork messaging, email, or Telegram. I provide regular progress updates, share demo links for deployed features, and use Git for transparent version control. I am responsive and ensure you always know the status of your project.

I use Jest and Vitest for unit and integration testing, React Testing Library for component tests, Playwright for end-to-end testing, and Supertest for API testing. I follow test-driven development (TDD) when appropriate and aim for meaningful test coverage that catches regressions without being brittle.

Yes, I have experience with both SQL databases (PostgreSQL, MySQL, SQLite) and NoSQL databases (MongoDB, Redis). I use Prisma, Drizzle ORM, and raw queries as needed. I integrate with third-party APIs including payment gateways, cloud services, mapping APIs, and social media platforms.

I am available full-time and can start new projects immediately. I communicate clearly about timelines, break deliverables into manageable milestones, and always build in buffer time for unexpected issues. I consistently deliver on or before the agreed deadline.

Yes, I provide comprehensive README files, inline code documentation, API documentation using tools like Swagger or JSDoc, setup guides, and deployment instructions. I am happy to walk through the codebase with your team and ensure a smooth handoff.
