I am a Backend Engineer specializing in building robust, scalable, and secure server-side applications. I focus on architectural design, secure authentication systems, and database optimization using the modern JavaScript ecosystem.
- Languages & Runtimes: Node.js,
- Frameworks: Express.js
- Databases & ORMs/ODMs: MongoDB, Mongoose,Prisma
- Architecture & Security: RESTful APIs, JWT (JSON Web Tokens), MVC Pattern, Password Hashing (Bcrypt)
- Tools & Workflows: Git, GitHub, Postman, Environment Configurations
A production-ready backend infrastructure demonstrating secure identity management and session handling.
- Stack: Node.js, Express.js, MongoDB, Mongoose, JWT
- Key Engineering: Implemented stateless session management via JWTs, password encryption, and custom middleware for protected, role-based API endpoints.
A highly structured backend system designed to handle complex data modeling and high-performance querying.
- Stack: Node.js, Express.js, MongoDB, Mongoose
- Key Engineering: Designed robust data validation, optimized Mongoose schemas, and implemented server-side filtering, pagination, and sorting for efficient dataset delivery.
My engineering workflows focus heavily on implementing industry standard patterns, including:
- Identity & Access Control: Advanced Authorization mechanisms, Role-Based Access Control (RBAC), and session security.
- System Reliability: Input validation, robust centralized error handling, and secure environment isolation.
- Database Engineering: Schema design, relational indexing, and performance optimization.
I collaborate with development teams and tech experts on active, production-grade backends. I bring a strong focus on writing modular, self-documenting code, setting up clean project baselines, and maintaining strict version control in agile environments.
