About Me

Backend Engineer & Full-Stack Developer building robust web and API architectures

My Engineering Focus

I am a Computer Science graduate from Lovely Professional University and currently working at PPN Solutions Pvt. Ltd. as a developer (since May 2026). My primary focus is designing backend architectures and APIs that are robust, highly scalable, and secure, while bridging them seamlessly to modern frontend layers.

I specialize in writing structured logic across diverse technology stacks: from enterprise Java / Spring Boot configurations and PHP Laravel MVC applications to fast event-driven Node.js modules. I focus on optimizing database query latency, establishing proper authorization rules, and structuring clean API documentations.

Solving Business Problems

Instead of just implementing technical lists, I approach engineering by focusing on solving concrete business needs:

  • System Security: Implementing OAuth2, JWT token rotations, and strict Role-Based Access Control (RBAC) to secure sensitive endpoints.
  • Process Automation: Orchestrating workflows and syncing databases using custom n8n configurations to reduce administrative overhead.
  • Database Optimization: Normalizing complex schemas, managing indices, and tuning PostgreSQL, MySQL, and MongoDB queries for maximum performance.
  • Deployment Reliability: Setting up clean Docker containers, separate environments (development/production), and automated CI/CD checks.

Learning & Growth

I actively refine my logic using Data Structures and Algorithms, having solved 100+ problems on LeetCode and other platforms. I am constantly building side projects to test modern architectural paradigms (like event-driven WebSockets and microservices networks).

My goal is to design backend architectures that stay fast and clean as business requirements grow.
