I turn complex problems into thoughtful digital experiences.

I'm Vishnutharan Bavachelvan — a Full-Stack Developer and IT undergraduate at the University of Vavuniya, Faculty of Applied Science, pursuing a B.Sc. (Hons) in Information Technology (2023 – Present). Selected for the IT Honours programme in 2026.
From responsive interfaces to autonomous agents, I like understanding how the pieces fit together. My work spans full-stack web and mobile applications, Java-based backend systems, and distributed/parallel computing — and I care deeply about building things that are clean, reliable, and maintainable.

Explore topics I enjoy discussing
I enjoy thinking about the complete path from a user's interaction to backend processing and stored data — designing APIs, structuring data models, and connecting frontend state to server logic cleanly.
Building structured, maintainable backend services with Spring Boot. I'm interested in layered architecture, RESTful design, and how Java-based systems scale.
Building responsive, component-driven interfaces across web and mobile from a shared codebase. I care about clean component structure, state management, and cross-platform UX consistency.
Reliable applications depend on reliable data. I enjoy exploring how schemas, constraints, triggers, and validation rules preserve integrity as information changes — and where responsibility belongs between the application and its database.
Parallel execution adds another dimension to problem solving. I'm interested in MPI collective operations, OpenMP thread coordination, CUDA GPU parallelism, and the cost of communication in distributed systems.
A selection of platforms, services, and experiments. Built with curiosity. Refined through doing.

| Principle | What it means to me |
|---|---|
| Clarity | Make the intent of the code easy to understand. |
| Correctness | Think carefully about assumptions, inputs, and edge cases. |
| Efficiency | Look for unnecessary computation and resource use. |
| Maintainability | Keep solutions structured so they can evolve. |
| Curiosity | Understand the ideas behind the tools and techniques. |
I'm open to internships in full-stack, frontend, and backend development — remotely worldwide or on-site in Sri Lanka.
