Divyanshu Kumawat

• Architect and deliver production-grade full-stack applications end-to-end, independently owning the complete software development lifecycle: database design, REST APIs, React frontends, testing, and deployment.
• Conduct peer code reviews within a distributed remote team, identifying regressions and improving code quality prior to production releases.
• Contribute across React.js, Node.js, Express.js, MongoDB, and third-party API integrations on multiple client-facing applications, supporting feature development and platform scalability.

• Reduced initial bundle size by ~35% through lazy loading and code-splitting, cutting load times on critical user flows from ~4s to under 2s.
• Built and shipped 3+ production UI features with reusable component architecture, reducing reported UI bugs by 40% over the internship duration.
• Managed task lifecycles using Jira in an Agile Scrum environment; participated in daily stand-ups and sprint planning, ensuring 100% on-time delivery of feature milestones.

• Built production-grade React applications with hooks (useState, useEffect, useContext, useMemo, useCallback), Redux Toolkit for state management, React Router for navigation, and performance optimizations via lazy loading and memoization.
• Developed backend systems with Node.js and Express.js — covering middleware architecture, JWT authentication, bcrypt password hashing, Multer file uploads, WebSockets with Socket.io, Redis caching, and Razorpay payment gateway integration.
• Implemented advanced MongoDB patterns including aggregation pipelines, indexing strategies, Mongoose population for relational data, and Atlas cloud deployment.
• Practiced DSA fundamentals (arrays, linked lists, stacks, queues, trees, graphs, sorting, searching) and Git/GitHub workflows.
• Completed modules on Generative AI integration (LangChain, ChatGPT/Gemini APIs), Progressive Web Apps, SEO principles, and Next.js SSR/SSG with deployment on Vercel and Netlify.

Bachelor of Computer Applications (BCA) — 6th Semester, University of Rajasthan (NEP 2020).

• Pursuing a 3-year BCA covering full-stack web development, data structures & algorithms, database systems, OOP through C++/Java, and applied computing.
• Core coursework: Programming in C, Web Application Development, DBMS (MySQL), Operating Systems, Data Structures, OOP via C++ and Java, Python, AI & Machine Learning, Data Science, Cloud Computing, and .NET Framework with C#.
• Applied skills through lab-intensive practicals — building REST APIs, implementing sorting/search algorithms, designing ER diagrams, writing Linux shell scripts, and running ML experiments with scikit-learn and pandas.
• Completed electives in Software Engineering (SDLC, Agile, COCOMO, testing strategies), Computer Networks, and Mathematics & Statistics, building a rigorous theoretical and practical foundation.
