Hi, I'm
Anshika
Second-year ECE student at IIIT Allahabad with a deep interest in backend development, DevOps, and system design. I love breaking things open to see how they work — contributing to open source, building distributed systems, and occasionally losing sleep over integer overflows. Obsessed with correctness and writing software that doesn't lie to you.
About Me
I'm a B.Tech ECE student at IIIT Allahabad (2024–2028) passionate about backend systems and open source. I contribute to Node.js core with merged PRs in C++ and JavaScript — fixing runtime bugs and improving API correctness. I build distributed systems like job queues and rate limiters, and I'm actively sharpening my DSA skills with a LeetCode rating of 1722 and Codeforces Specialist rank.
