Building systems & full-stack products.
Computer Science student at Parul University. Focused on backend-leaning systems architecture, Java data structures and algorithms, and developing robust web applications.
Engineering complete systems from first principles.
I am a Computer Science undergraduate focused on software engineering, system architecture, and building production-grade applications. My foundation is rooted in daily problem-solving—having solved over 600+ algorithmic problems in Java to develop strong spatial-temporal reasoning, memory management intuition, and algorithmic rigor.
I don't view software development through the narrow lens of a single tier. Instead, I approach engineering holistically: taking an idea from data schema design and API contracts down to responsive frontend interfaces, secure authentication, external API integrations, and cloud deployment. Whether designing a distributed rate limiter or multi-agent research pipeline, I care about predictable behavior under load and clean system boundaries.
My curiosity lies in how complex systems operate beneath the surface. I invest heavily in fundamental computer science primitives—Database Management Systems (DBMS), Operating Systems, Computer Networks, Object-Oriented Programming (OOP), and Low-Level Design (LLD)—because understanding these fundamentals enables me to write cleaner, more resilient software.
For me, technologies like AI agents, Redis caches, or serverless functions are execution tools to solve real engineering bottlenecks, not shortcuts. I aim to contribute to product-driven engineering teams as a Software Engineering Intern.
