Building secure APIs, scalable systems,
and AI‑powered applications.

Passionate about building secure APIs, scalable systems, and AI‑powered applications.
Secure. Scalable. Built for production.
I'm Aavishkar Chaudhari, a pre-final-year Computer Engineering student at PCCOE Pune with a strong focus on backend engineering. I build software that goes beyond working locally — systems designed to be secure, maintainable, and ready for real-world use.
My primary expertise is Java and Spring Boot, where I design production-style REST APIs, implement secure authentication and authorization, optimize database performance, and build scalable backend architectures. Good software isn't defined only by features, but by reliability, clarity, and the ability to evolve as requirements grow.
I've also contributed to open source through GirlScript Summer of Code, finishing in the top 4% globally (ranked #1,790 of 47,951 participants) — an experience that sharpened how I read unfamiliar codebases, review contributions, and communicate technical decisions clearly.
Designing secure, maintainable REST APIs using layered architecture, dependency injection, and clean engineering practices.
Implementing JWT authentication, role-based authorization, refresh tokens, input validation, and production-focused API security.
Optimizing PostgreSQL and MongoDB through efficient schema design, indexing, pagination, caching, and query optimization.
Writing maintainable code, documenting APIs, contributing to open source, and building software that stays reliable beyond the first release.
Today, I'm focused on becoming a backend engineer capable of building systems that are not only functional, but dependable, scalable, and enjoyable for developers to maintain.
A snapshot of my GitHub ecosystem — projects built, code shipped, and a relentless pursuit of technical excellence.

Seeking full-stack development roles. Eager to solve complex problems and build scalable solutions with a modern tech stack.

Production-grade REST API with 25+ endpoints featuring JWT auth, refresh token rotation, RBAC, OWASP XSS sanitization, AI-powered draft generation, and real-time engagement tracking. Built with enterprise security patterns, N+1 query elimination, and deployed via Docker on Render.




Clinic management system with online appointment booking, enquiry tracking, and role-based authentication for patients and admins. Built for a real-world client.
A practical set of tools and technologies I use to build scalable and reliable applications.


A timeline of technical growth — from open-source contributions to real-world full-stack development, building scalable solutions and impactful projects.

Finished in the top 4% globally among 47,951 participants, with a final global rank of #1,790 through PR contributions across the Open Source track.
