During my time at Bluekode Solutions and KPN, I advanced my backend development expertise, specializing in Node.js, and NestJS, and building efficient Backend for Frontend (BFF) layers for e-commerce solutions.Key Responsibilities and Contributions:1. Advanced Backend Development: o Gained proficiency in Node.js and NestJS, focusing on scalable service architecture. o Implemented Fastify services, splitting the system into independent modules like:  Authentication: Secure token-based login and session management.  Catalog: Managing product details and inventory.  Order: Handling customer orders and statuses.  Cart: Managing user cart actions and data. o Developed and connected all these services under a unified BFF layer for optimized frontend interaction.2. Database Expertise with PostgreSQL and Knex.js: o Learned PostgreSQL and utilized Knex.js for writing optimized and structured database queries. o Designed efficient schemas to store and retrieve large-scale e-commerce data.3. Excel File Handling and Sync Services: o Built features to handle Excel file uploads, ensuring data was validated and correctly stored in the database. o Developed a sync service to manage real-time updates:  Set up a mechanism to check and sync data using a flag system (true/false) every second.  Ensured the latest data was fetched by hitting APIs, processing the response, and storing it in the database.4. E-commerce Software Implementation: o Contributed to developing a robust e-commerce platform by integrating APIs with backend services. o Ensured smooth data flow and synchronization between frontend and backend systems. o Played a critical role in optimizing the architecture for better performance and scalability. Key Skills and Tools:

At KPost, I worked as a Software Engineer, enhancing my skills in backend development, database management, and project-specific implementations.Key Responsibilities and Contributions:1. Backend Development with Node.js: o Adapted to a unique file structure for better organization and modularity. o Created helper functions to validate and reuse input logic, reducing code duplication and increasing maintainability.2. Database Management with MongoDB: o Shifted focus to NoSQL databases, implementing MongoDB to store and manage project data. o Designed optimized database schemas to handle dynamic and hierarchical data structures.3. Project Management Software – Planning and Scheduling: o Developed a system to track day-to-day tasks and work allocation for team members. o Implemented features for creating tasks, tracking actual durations, and setting deadlines. o Built functionality for uploading Excel files to import tasks into the database, enabling seamless bulk task creation.4. Reporting and Analytics: o Designed and generated comprehensive task reports, including:  Daily, Weekly, and Monthly task progress reports.  Appraisal reports for performance reviews based on team and project metrics. o Integrated team-wise and project-wise reports to assist in strategic decision-making.

As a Software Engineering Intern, I focused on backend development with Node.js and Express.js, gaining hands-on experience in full-stack project implementation.Key Learning and Contributions:1. Backend Development: o Learned Node.js and Express.js, focusing on scalable API development. o Explored and implemented various npm packages to enhance functionality. o Designed and implemented a proper folder structure to ensure maintainability and scalability.2. Authentication & Authorization: o Developed secure token-based authentication for projects. o Set up token expiration logic and ensured secure data access across services.3. Project Work – Hiring & Rack Management: o Worked on a hiring project and a rack management system, involving requirement analysis, design, and implementation. o Utilized tools like Jira to manage tasks, track progress, and report updates. o Created flow charts and sequence diagrams to visualize processes and explain the design to stakeholders.4. Software Development Lifecycle: o Contributed to end-to-end development, from requirement analysis to deployment. o Verified all test cases to ensure functionality, reliability, and edge-case handling. o Wrote and executed unit test cases using the Jest framework, achieving complete test coverage.Key Tools and Skills Acquired: • Node.js, Express.js, Jest, npm, Jira. • Requirement analysis, flow chart and sequence diagram creation. • Testing, debugging, and project documentation.
