Hello I'm
Varun Bali
As a dedicated and motivated Computer Science Engineering student, I aim to leverage my strong foundation in programming, data structures, and software development to contribute to innovative projects.Committed to continuous learning, problem-solving, and collaborating within dynamic teams to develop impactful technology solutions.
My Services
I provide a comprehensive range of development services to help bring your ideas to life
Full Stack Development
Building end-to-end web applications using React 19 and Next.js 16 on the frontend with Spring Boot on the backend. Experienced in designing responsive, accessible UIs with Tailwind CSS and TypeScript, and wiring them to robust Java REST APIs. Delivered full-stack projects like Civis (civic issue platform) and ShopSphere (e-commerce) with role-based dashboards, real-time data, and concurrent multi-user support.
RESTful API & Microservices
Designing and building secure, scalable RESTful microservices with Spring Boot and Spring Security. Proficient in JWT-based authentication, fine-grained role-based access control, and third-party integrations such as Razorpay payment gateway with webhook handling and signature verification. Experienced with unit and integration testing using JUnit 5 and Mockito, and familiar with CORS, Gradle, and agile development practices.
AI & Computer Vision
Developing real-time AI-powered systems using Python, OpenCV, and NumPy. Built a hand-gesture recognition pipeline with HSV skin-color detection and contour analysis, classifying four gestures and mapping them to system-level media commands via pynput — achieving sub-100ms response latency through NumPy vectorisation. Experienced with Pandas for data processing and applying computer vision techniques to productivity and automation use cases.
Database Design
Architecting and managing both relational and NoSQL databases to support complex application workflows. Experienced with PostgreSQL for structured schemas and complaint lifecycle management (Civis), and MongoDB for flexible document storage in high-throughput e-commerce platforms (ShopSphere). Skilled in data modelling, schema design, query optimisation, and integrating databases with Spring Boot and Next.js backends.
