Building high-performance backend architectures and system-level applications.
I'm a Software Engineer who loves building fast, scalable backend systems. Right now, I'm leading the development of a few complex platforms from the ground up—handling everything from initial system design to final production. When I'm not architecting APIs, you'll find me sharpening my problem-solving skills by mastering Data Structures & Algorithms in C++.

Engineering Focus & Recent Architecture
Lead Developer • Highly Scalable Microservice Architecture
A production-ready backend engine designed for a high-concurrency social blogging platform. Built with a focus on strict type safety, asynchronous processing, and robust security middleware (including custom bot interception).
- Tech Stack: Strict TypeScript, Node.js, Express, PostgreSQL, Drizzle ORM, Redis, BullMQ.
- Architecture Highlights:
- Advanced Authentication: JWT access/refresh token rotation & secure OTP email verification.
- Decoupled Async Processing: Dedicated BullMQ/Redis worker threads handling email distribution, media processing, and interaction queues without blocking the main event loop.
- Security & Performance: Custom bot-interceptor middleware, Redis-backed rate limiting, and HTTP request logging.
- Relational Data Modeling: Highly normalized PostgreSQL schema handling complex relationships (posts, hierarchical comments, likes, shares, and follows) strictly typed via Drizzle ORM.
Lead Developer • B2C E-Commerce Platform
The core architectural backbone for a high-traffic B2C e-commerce platform. Engineered to handle a highly dynamic product catalog, secure payment lifecycles, and advanced user role management.
- Tech Stack: Strict TypeScript, Node.js, Express, MongoDB (Mongoose), Redis, Cloudinary.
- Architecture Highlights:
- Polymorphic Product Catalog: Complex data modeling to support diverse inventory types (Apparel, Bangles, Fabrics, Innerwear, Accessories) under a unified system.
- Multi-Layer Security: Role-Based Access Control (RBAC) separating Admin and Public traffic, alongside Google OAuth and OTP-based authentication.
- Media & CDN Integration: Automated media uploads, optimization, and delivery via Cloudinary.
- Performance Optimization: Redis caching layers for catalog retrieval and session state management.
Daily Mastery & Problem Solving
A comprehensive, actively maintained collection of Data Structures and Algorithms solutions implemented in C++. This repository documents my mastery of core CS concepts and advanced competitive programming patterns.
