LET'S BUILD SOMETHING REAL!
A collection of systems, platforms, and applications built with clean code, rigorous optimization, and modern software architectures.
Internship
QuickIntell
Software Engineering Intern
United States (Remote)
- Architected type-safe database schemas with Prisma and PostgreSQL, incorporating senior engineer code review feedback to align with existing architectural patterns and ensure consistent data contracts between independently deployed frontend and backend services.
- Onboarded into an existing production codebase and built an analytics module in Node.js and TypeScript to process and aggregate complex event data structures for internal reporting dashboards.
- Implemented JWT-based authentication and session management with input validation and sanitization across REST API endpoints, handling HTTP request/response lifecycles and enforcing secure data contracts between frontend and backend services.
Featured Projects
LOBE
HFT-grade matching engine · C++17 + WebSocket market feed
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
Gamify LeetCode grind · Chrome Extension (MV3) · Web Audio API
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 Backend
Role-based access control · Prisma ORM · Swagger docs · PostgreSQL
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
High-concurrency backend · Redis · Stripe Webhooks
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.
ThinkYr
Socket.io · Redux · Real-time sync
A real-time collaborative planning tool where multiple users work on shared boards simultaneously with conflict-free state sync.
- Real-time multi-user sync via Socket.io rooms and namespaces.
- Optimistic UI updates with Redux middleware rollback on conflict.
- Presence indicators and live cursor tracking per user.
