As a backend developer, I specialize in creating efficient, secure, and scalable server-side systems that drive robust web and mobile applications. I have developed and deployed backend architectures tailored to meet diverse business needs across industries such as fintech, e-commerce, and media technology.
Core Capabilities
- API Development and Integration
I design custom APIs using RESTful principles and GraphQL, enabling seamless data exchange between systems. My approach focuses on scalability, security, and ease of use, making APIs reliable and developer-friendly. I also integrate applications with third-party APIs, payment gateways, and external services like email providers and cloud-based storage systems.
- Authentication and Security
Ensuring secure access to applications is a cornerstone of my expertise. I implement authentication systems using JWT, OAuth, and session-based methods while enforcing robust authorization mechanisms such as role-based access control (RBAC). Additionally, I integrate social login options (e.g., Google, Facebook) to enhance user convenience.
- Database Design and Management
I am proficient in working with both relational (MySQL, PostgreSQL) and NoSQL (MongoDB) databases. My work includes designing efficient schemas, optimizing query performance, and managing large-scale data operations. I also handle complex database requirements such as migrations, backups, and advanced aggregation queries.
I develop real-time functionalities such as live notifications, collaborative tools, and chat systems using WebSocket and Socket.IO. These implementations ensure smooth and instant interactions between users, enhancing user engagement.
I automate repetitive backend tasks using cron jobs and custom schedulers. Examples include data synchronization, report generation, and scheduled system maintenance.
