I'm a Computer Science student at VIT-AP who enjoys building things that are fast, efficient, and technically challenging.
Most of my time goes into three areas:
- Competitive Programming
- Systems Programming
- Performance Engineering
I love understanding how software works beneath the surface — from memory management and operating systems to low-latency packet processing and backend infrastructure.
⚡ Building systems projects in C++ and Linux
📚 Learning more about operating systems, networking, distributed systems, and performance optimization
🏆 Preparing for ICPC, coding contests, and software engineering interviews
🚀 Exploring low-latency systems inspired by HFT infrastructure
I started competitive programming out of curiosity and quickly got addicted to the problem-solving process.
Highlights
- Codeforces Specialist (Max Rating: 1525)
- CodeChef 4★ (Max Rating: 1845)
- ICPC Huawei Winter Challenge 2025 — Rank 819 / 36,000+
- 500+ DSA problems solved across platforms
Some of my favorite topics are:
- Dynamic Programming
- Graph Algorithms
- Trees
- Number Theory
- Greedy Optimization
An adaptive Linux memory governor written in C++.
Instead of waiting for the system to run out of memory, Memopt++ proactively manages memory pressure using:
- cgroups v2
- ZRAM compression
- KSM deduplication
The goal is simple: keep Linux systems responsive under heavy workloads.
Tech: C++17, Linux, System Programming, Memory Management
A C++20 low-latency trading packet processor inspired by real trading system architectures.
It processes binary market-data packets, updates an in-memory L2 order book, runs trading logic, performs risk checks, and generates outbound order packets through DPDK-style networking paths.
What I learned while building it:
- DPDK fundamentals
- Packet processing
- Order book design
- Latency-aware engineering
- Performance benchmarking
Verified application-side latency benchmarks reached sub-microsecond levels in controlled environments.
Tech: C++20, DPDK, Linux Networking, Performance Engineering
A multimodal AI assistant capable of processing medical images, text queries, and voice interactions.
Built to explore the intersection of Computer Vision, NLP, and real-time AI systems.
Tech: Python, Machine Learning, Computer Vision, NLP
A Chrome Extension that helps contributors quickly discover GitHub repositories for open-source organizations participating in Google Summer of Code.
Reduced repository discovery time significantly by automating the search process.
Tech: JavaScript, Chrome APIs, DOM Manipulation
A privacy-focused application built using zero-knowledge proofs.
Implemented zk-SNARK circuits and on-chain verification to explore privacy-preserving blockchain systems.
Tech: Solidity, Circom, React, Node.js
Languages
C++, Python, JavaScript, Solidity
Areas
- Systems Programming
- Operating Systems
- Networking
- Backend Engineering
- Distributed Systems
- Performance Optimization
Tools
Linux, Git, Docker, CMake, DPDK, Node.js, React
When I'm not building projects, you'll probably find me:
- Solving Codeforces contests
- Reading about operating systems and networking
- Exploring low-latency trading systems
- Learning how large-scale backend systems work
- Breaking things and figuring out why they broke
