About
I'm Arsh Tiwari, a Computer Science undergraduate (CGPA: 9.2) with hands-on experience building scalable full stack and AI powered applications. I've worked as a Software Developer Intern at MathonGo (serving 1L+ users), Developer Intern at Mappls, and Software Developer Intern at Eterna Infotech, contributing to production-grade platforms and intelligent systems.
I have a strong understanding of computer science fundamentals, including Data Structures & Algorithms, Operating Systems, DBMS, Computer Networks, and System Design (LLD & HLD). I actively participate in competitive programming and hackathons to sharpen my problem-solving skills.
Beyond full-stack development, I am genuinely fascinated by Generative AI. I explore LLMs, retrieval systems, and AI-powered applications to understand how intelligent systems can solve practical problems.
I also publish tech content on YouTube, sharing insights on Data Structures & Algorithms, System Design, and practical engineering concepts.
Disciplined, self-driven, and constantly learning, I thrive in dynamic environments where curiosity, innovation, and meaningful work are valued. I'm always looking to collaborate, innovate, and grow.
I absolutely love Competitive Programming

Software Developer Intern
Mathongo
Bangalore, Karnataka, India (Onsite)
Revamped the Quizrr platform (1L+ users) using React.js, improving page load time by 35% and boosting user engagement through consistent, scalable UI architecture.
Built the Notebooks feature end-to-end, designing reusable components and integrating backend APIs for data persistence, increasing feature adoption by 25% and improving session retention.
Implemented request deduplication for API calls by caching in-flight requests, reducing duplicate network calls by 40% and improving performance of data-heavy workflows.
Integrated RabbitMQ to handle asynchronous tasks of note-saving and analytics, offloading heavy operations from synchronous APIs and reducing API response time by 25% during peak usage.
Software Developer Intern

ApplyStack is a full stack job application tracker I built because I was managing 30+ applications in Google Sheets and losing track. It lets you log every application with its full lifecycle, applied, shortlisted, interviews, offer add tasks around them, save reusable cold message templates, and export everything to PDF. Under the hood it uses Redis caching to reduce DB load, RabbitMQ for async email delivery, and the whole thing runs in Docker so setup is one command.
GoSearch is a lightweight, self hosted full text search engine that can index a million documents and answer queries in under 2 ms, with zero external dependencies beyond Go itself, built to be a cost free alternative to the amazing Elasticsearch.
gortc is a work-in-progress real-time video conferencing platform written in Go using Pion, WebRTC, Fiber, and WebSockets supporting peer-to-peer video rooms, live streaming, and real-time chat with auto-reconnect and TURN relay fallback.
Signal-X is an hackathon-winning project that leverages AI and advanced computer vision to optimize real-time traffic flow. Using YOLO-based vehicle detection, Arduino-controlled signals, and MapMyIndia's geospatial analytics, it dynamically adjusts traffic lights to reduce congestion, prioritize emergency vehicles, and improve road safety.
Incentix is a decentralized platform designed to reward contributors for their work on open-source projects by rewarding PR system. Contributors can access bountied issues, complete them, and earn cryptocurrency through automated smart contract payments. built with blockchain tech, it promotes transparency, security, and accountability in open-source contributions.
Recap is an innovative study companion designed to revolutionize how students organize and interact with their study materials. Our platform leverages artificial intelligence to create an intelligent note-taking ecosystem that grows with your learning journey.
