About Koushik Kumar Bug

Koushik Kumar Bug WB, India I am an experienced software developer with a Master in Computer Applications from BIT Mesra and a proven track record in full‑stack and open‑source projects. In my recent Google Summer of Code work on Chromium, I migrated audio test files from audit.js to testharness.js. I also built and integrated the Perplexity Sonar AI into Chromium’s Omnibox to deliver AI‑powered search results and contextual summaries instantly, showcasing my C++ and WebUI expertise. In addition to this, I had built a custom WebUI for Android Chromium browser for WootzApp Inc. In addition to this, in my work at AMAZON, I Contributed to the development of AI models by meticulously annotating and verifying large-scale video datasets from warehouse operations, focusing on precise object localization to generate high-quality training data achieving 99.8% label accuracy and reducing review cycles by 30%. • Ensured data integrity & AI benchmark adherence through rigorous application of SOPs, annotation guidelines, and Quality Assurance protocols, directly impacting ML system performance in robotic automation and logistics. During my Web Developer internship at PrepInsta Technologies, I architected a real‑time “PrepChat” feature using WebSockets and JWT, boosting engagement by 40% and improving system performance by 25%. I’ve designed and delivered complex applications— a real‑time BIT Mesra alumni chat platform supporting 70+ concurrent users, and a cross‑chain ETH → WETH bridge contract DApp on Sepolia‑Polygon using Distributed Ledger Technology. Combining strong fundamentals in algorithms, data structures, and system design with hands‑on skills in JavaScript, Python, C++, Node.js, Solidity, and blockchain tooling, I excel at driving projects from concept through deployment. I thrive in collaborative, agile environments and am passionate about delivering clean, maintainable code that scales. I am eager to leverage my backend, Web3, and Chromium development experience to contribute to innovative, high‑impact projects.
