VENTURE SHOWCASE
Low-Latency Limit Order Book & Matching Engine
A price-time priority (FIFO) order book matching engine in C++17 achieving P50 latency of 102ns and P99 of 378ns across 100K operations, with a live TypeScript/Node.js WebSocket feed server bridging the engine via IPC.
- Engineered a price-time priority (FIFO) order book matching engine in C++17 achieving P50 latency of 102ns and P99 of 378ns across 100K operations.
- Designed core data structures using std::map for O(log N) price-level access and std::unordered_map for O(1) order cancellation by ID, supporting Limit, Market, and Cancel order types.
- Built a real-time WebSocket feed server in TypeScript/Node.js bridging the C++ engine via stdin/stdout IPC, broadcasting live trade events and order book snapshots to connected clients.
- Wrote a Python benchmarking harness using std::chrono-timed C++ output to profile latency distributions across 100K operations, validating P50/P99 targets under simulated order flow.
LeetCode Sound FX — Chrome Extension
A Manifest V3 browser extension that gamifies LeetCode by playing customizable sound effects for Run and Submit actions, processing local audio using the Web Audio API.
- Engineered a Manifest V3 browser extension to play custom audio feedback on LeetCode Run/Submit actions and Wrong Answers.
- Architected a non-intrusive dual-content-script setup, utilizing an injected script to intercept page-context fetch/XHR events and communicate them to isolated content scripts.
- Implemented high-performance, low-latency audio playback using the Web Audio API to bypass browser CORS restrictions and eliminate bulky DOM dependencies.
- Designed a popup interface with options for file upload, active toggle buttons, and independent volume sliders utilizing Chrome extension local storage.
Finance Data Processing & Access Control Backend
A production-ready REST API built with Node.js, TypeScript, Express, Prisma ORM, and SQLite/PostgreSQL, featuring secure JWT-based login, role-based permissions (RBAC), transactional CRUD, soft deletes, and automated Swagger documentation.
- Engineered a production-ready financial management REST API in TypeScript, implementing secure JWT stateless authentication and bcrypt password hashing.
- Designed and implemented fine-grained Role-Based Access Control (RBAC) supporting VIEWER, ANALYST, and ADMIN permissions for transaction management and user administration.
- Integrated Prisma ORM with SQLite for local development and PostgreSQL support for production, deploying soft deletes (isDeleted) to maintain data audit trails.
- Developed custom dashboard analytics endpoints to calculate real-time category breakdowns, transaction summaries, and monthly/weekly trend charts.
- Authored comprehensive integration tests using Jest and Supertest to validate authentication logic, access control barriers, and database transactions.
Baskit – Scalable E-Commerce Platform
A full-stack e-commerce platform engineered for high concurrency with a Redis caching layer, Stripe payment integration, and decoupled modular architecture.
- Architected a high-concurrency e-commerce backend handling 500+ daily transactions with strict data consistency via MongoDB.
- Engineered a custom caching layer using Redis, reducing database read load by 40% for high performance and reliability.
- Implemented secure payment pipelines using Stripe Webhooks and ensured data consistency with MongoDB transactions.
- Designed with decoupled modules to support future feature extensions without changes to core business logic.
I build systems that run at nanosecond scale.
Final-year CSE undergrad at IIIT Bhopal, currently Rank 1 in my department. I build low-latency systems in C++ and ship full-stack products that work in production — not just in demos.
My flagship project LOBE is a C++17 limit order book engine with a real-time WebSocket market feed, clocking P50 latencies of 102ns across 100K ops. I care deeply about how code interacts with hardware, and I think most software is far slower than it needs to be.
Outside of code I grind competitive programming (LeetCode Knight, 1933 rating, AIR 70 nationally, 900+ problems solved), prep system design, and actively hunt for SDE roles at companies where performance actually matters.
