About Divyanshu Kumar

Software Developer || B.Tech (CSE), NIT Manipur (2025)|| MERN Stack || System DesignFrom ideation to implementation, I enjoy building robust backend systems and owning problems end-to-end with a strong focus on scalability, performance, and maintainability.I am a Software Developer and Computer Science Engineering graduate from NIT Manipur (Class of 2025) with hands-on experience in backend development using Node.js and Express.js, and strong fundamentals in system design and Low-Level Design (LLD).Backend & Design Strengths:• Low-Level Design (LLD) and working knowledge of High-Level Design (HLD)• Object-Oriented Programming, SOLID principles, design patterns, modular architecture• Data Structures and Algorithms (DSA) for performance-driven backend systemsBackend Tech Stack:• Node.js, Express.js, RESTful API design• MongoDB and SQL-based databases• Database schema design, normalization, and data modelingSQL & Data Expertise:• Complex SQL queries using joins (INNER, LEFT, RIGHT)• Indexing strategies for performance optimization• Query optimization, execution plans, and efficient data retrieval• Transactions, constraints, and data integrityCore CS Fundamentals:• Operating Systems• DBMS• SQLTools & Practices:• Git for version control and collaborative development• GitHub for code management, reviews, and CI workflows• Postman for API testing, debugging, and validationI have worked across the complete backend development lifecycle including requirement analysis, system design (HLD/LLD), API development, database design, testing, debugging, and deployment. My exposure to product thinking and management fundamentals allows me to translate business requirements into reliable and scalable backend solutions.I value clean code, performance optimization, and scalable architecture. Driven by curiosity and continuous learning, I actively explore backend scalability, system design, and modern engineering practices.Open to Backend Developer, Software Engineer, Full Stack, MERN, and Product Engineering roles.Let’s connect and build high-impact backend systems together.

Experience

1. Software Engineer Ii

   HCLSoftware

   Sep 2025 — Present · Noida, IN

   Worked across the complete Software Development Life Cycle (SDLC), including designing, developing, and maintaining scalable software components.2. Implemented secure API wrapper functions to prevent direct API exposure, improving system security, abstraction, and reliability.3. Developed generic, reusable, and user-facing functions to ensure consistent and standardized API interactions across multiple applications.4. Identified the minimum and critical set of testing parameters required for UI-driven validation, reducing unnecessary input complexity and improving test efficiency.5. Contributed to the implementation of the Builder Design Pattern, enhancing object creation flexibility, code readability, and long-term maintainability.
