Hi I'm a Fullstack developer creating robust web applications.

A web platform that enables students to book supervision slots with lecturers, submit project or thesis topics, and receive automatic schedule notifications through an admin dashboard. Built RESTful APIs for booking, user authentication, scheduling, and topic management using Node.js + Express.js. Created a relational database schema with MySQL, optimized for efficient queries and client relations. Implemented JWT-based authentication, role-based authorization, and secure file upload for topic documents via formidable + AWS S3 SDK. Automated meeting creation and notifications via Nodemailer + Node-schedule. Managed backend development lifecycle using Scrum methodology. Deployed backend on VPS (Ubuntu) using Docker, Nginx as a reverse proxy, and PM2. Led a 4-member backend team, handling API architecture, Git workflow, and code reviews.

Built a fully responsive frontend using Next.js (v14) with TypeScript, integrating modern UI frameworks such as ShadcnUI, React 18, and Redux Lite for clean, reusable components. Implemented global state management with Zustand and localStorage for seamless user and cart persistence. Integrated React Query (TanStack) for efficient server state synchronization and caching of API responses. Implemented multi-language support with next-intl and dark/light themes. Integrated real-time updates through Socket.io to client for live order status and kitchen notifications. Generated QR codes for table-based ordering using qrcode and html-to-image. Deployed the frontend on VPS (Ubuntu) using Docker and Nginx for scalable hosting.

Developed a scalable fullstack architecture using NestJS (backend) and React.js (frontend) with a focus on clean modular design and strong typing with TypeScript. Built product, order, and user management modules with Prisma ORM and PostgreSQL, implementing nestjs-zod for input validation. Implemented authentication and authorization via JWT, with role-based access for Customer (user) and Admin. Created real-time order tracking and stock updates using Socket.io. Designed background job processing with BullMQ + Redis to handle tasks like order confirmation, inventory updates, and notifications. Integrated Google OAuth login and AWS S3 storage for product image uploads. Deployed backend and frontend on VPS (Ubuntu) using Docker, Nginx, and PM2, ensuring stable CI/CD and version control with Git. Enhanced data fetching and caching using React Query (TanStack) and optimized user sessions with Zustand and Zod validation.

Developed a comprehensive healthcare microservices platform with 10+ independent services including Auth, Booking, Payment, Provider, Staff, and Media services. Built GraphQL API Gateway for unified client communication and implemented gRPC for efficient inter-service communication. Designed and implemented microservices using NestJS framework with Prisma ORM and PostgreSQL databases for each service. Created service booking system with availability management, provider onboarding and verification system, and payment processing integration with Stripe. Implemented media service with AWS S3 for file storage and image optimization. Built real-time notification system across services. Integrated Python ML models for AI-powered service recommendations. Containerized all services with Docker and deployed on Google Cloud Platform (GCP) with Cloud Build for CI/CD automation.
