I am a Backend Engineer focused on building scalable, production-grade systems. My expertise lies in designing robust APIs, optimizing database architectures, and implementing microservices. I am passionate about clean code, system design patterns, and distributed systems.
- Current Focus: Advanced Backend Architecture, System Design, and Go ecosystems
- Core Stack: TypeScript, Node.js, NestJS, Go (Golang), PostgreSQL
- Interests: Microservices, Database Optimization, Scalability Patterns
- API Development: Designing RESTful APIs with a focus on performance and security.
- System Architecture: Experience with Microservices architecture, Reverse Proxies (Nginx), and Event-Driven patterns.
- Database Management: Schema design, complex querying, and performance tuning (SQL & NoSQL).
- Infrastructure: Containerization using Docker and cloud deployment on AWS.
I maintain a strong grasp of Data Structures and Algorithms (DSA) through consistent practice.
- LeetCode: 500+ Problems Solved
- Proficiency: Arrays, Strings, Trees, Dynamic Programming, and Graph Algorithms.
- Focus: Writing efficient, optimized code with low time and space complexity.
I am always open to discussing backend engineering, system design, or potential collaborations.
