01
Production web apps
Developed and maintained production-grade web applications using Next.js, React.js, TypeScript, Node.js, and REST APIs.
02
Reusable UI systems
Designed responsive, reusable frontend components with React.js, Next.js, Tailwind CSS, and TypeScript for scalable application development.
03
REST APIs & services
Developed backend services and REST APIs with Node.js and Express.js, with structured request handling and frontend–backend integration.
04
Auth & access control
Implemented authentication and authorization with JWT, OAuth, and NextAuth.js for secure, role-based access.
05
Data & persistence
Integrated MongoDB and PostgreSQL with Mongoose and Drizzle ORM for data management and persistence.
06
State at scale
Managed application state with Redux Toolkit and optimized client-side data handling for complex workflows.
07
API integration & validation
Integrated APIs and validated endpoints with Postman for reliable communication between frontend, backend, and external services.
08
Redis performance
Worked with Redis for application-level data handling and performance-oriented backend workflows.
09
Git & collaboration
Used Git and GitHub for source control, branching, collaboration, and version control.
10
Docker & delivery
Containerized environments with Docker and supported deployment workflows with Vercel and GitHub Actions.
11
Design to product
Collaborated with development and design teams to turn requirements and Figma designs into functional, responsive, user-focused applications.
