I build high-performance backend systems that power scalable, real-time applications. From APIs to databases, I focus on reliability, security, and clean architecture that holds up in production.
With a strong interest in system design and performance optimization, I enjoy turning complex ideas into simple, efficient solutions that deliver real value to users.
I'm Ayush Kumar, a Backend-focused Software Engineer with hands-on experience building scalable APIs, real-time systems, and data-driven platforms. Currently working at ResponseNet, I specialize in Node.js, PostgreSQL, Redis, and modern web technologies. My journey includes optimizing production applications for 1K+ users, reducing latency to under 1 second, and improving performance metrics by up to 35%. I'm passionate about system design, clean architecture, and delivering solutions that make a real impact. When I'm not coding backend services, I'm exploring new technologies like Go and Rust, or building side projects like ConfessBay and Store It that challenge me to think differently about scalability and user experience.
Throughout my career, I've had the opportunity to work across the full stack—from crafting responsive UIs with Next.js and SvelteKit to architecting secure backend services and real-time messaging systems. I graduated from VIT Bhopal with a degree in Computer Science, and since then, I've contributed to products that serve thousands of users daily. I believe in writing code that's not just functional, but maintainable, performant, and built with the end user in mind. Whether it's shaving off milliseconds from API response times or designing database schemas that scale, I'm always chasing that perfect balance between elegance and efficiency.
