About

I build backend systems that don’t break under load. I’m a backend-focused Software Developer who enjoys working on systems that deal with real-time data, concurrency, and scale. Most of my work revolves around designing reliable architectures where performance, fault tolerance, and data consistency actually matter. At Restroworks, I worked on a multi-tenant inventory and analytics system handling real-time POS data with 20+ concurrent workers. I built event-driven pipelines using BullMQ and Redis to offload heavy processing, improved system responsiveness with caching and pre-aggregation strategies, and ensured consistency using MongoDB transactions and optimistic concurrency control. I care a lot about how systems are designed — not just making them work, but making them reliable. I write modular, loosely coupled code so failures don’t cascade, and I use structured logging and clear workflows to make systems easier to debug and scale over time. Beyond that, I’ve built full-stack applications like real-time analytics dashboards and e-commerce systems, working across APIs, async processing, and frontend performance using React and Redux Toolkit. Recently, I’ve also been exploring AI-powered systems that process unstructured data using LLMs and OCR pipelines. I’m currently looking for Backend / Software Engineer / Full Stack roles where I can work on high-performance systems and continue growing in system design and distributed architectures. Tech stack: Node.js, Express, MongoDB, Redis, BullMQ, React, Redux Toolkit, MySQL, TypeScript, Java Feel free to reach out via LinkedIn or email me at nischaysharma04@gmail.com — always open to conversations and opportunities.
