If you are passionate about delivering clean, efficient, and production-grade solutions while collaborating in fast-paced Agile environments, we would love to hear from you.

Key Responsibilities

• Utilize TypeScript for type-safe development.

• Build reusable UI components with modular design principles.

• Apply performance optimization techniques such as lazy loading, code splitting, and memoization.

• Leverage CSS frameworks such as SASS/SCSS, Tailwind CSS, or Bootstrap for responsive UI.

• Work with Next.js for server-side rendering (SSR) and static site generation (SSG).

• Architect, build, and maintain backend APIs and microservices using Node.js and Express/NestJS.

• Implement secure authentication/authorization mechanisms (JWT, OAuth2, SSO).

• Work with RESTful APIs, WebSockets, and backend service integrations.

• Design, model, and manage relational databases using PostgreSQL.

• Implement optimized query patterns for scalability and performance.

• Write unit and integration tests using frameworks like Jest or React Testing Library.

• Maintain high code quality through version control, code reviews, and CI/CD pipelines.

• Collaborate with cross-functional teams in an Agile environment, participating in sprint planning, code reviews, and daily standups.

• Communicate effectively with clients and internal stakeholders, providing technical insights and solutions.

• Familiarity with cloud services such as AWS, Vercel, Supabase, and Neon.

• Knowledge of modern build tools such as Webpack, Vite, or Parcel.

Qualifications, Skills, and Experience

• Bachelor’s degree in Computer Science, Software Engineering, or related field.

• 5–6 years of professional experience as a Full Stack Developer.

• Strong expertise in React.js, TypeScript, Node.js, and Express/NestJS.

• Proficiency in front-end technologies: HTML5, CSS3, JavaScript (ES6+), and modern UI frameworks.

• Solid understanding of microservices architecture and secure API development.

• Experience in PostgreSQL database design and query optimization.

• Familiarity with Next.js, CI/CD pipelines, and containerized environments (Docker).

• Strong communication skills and prior experience in client communication.

• Experience in Agile development environments.

• Exposure to AWS, Vercel, Supabase, or Neon is a plus.
