This is me.
Hi, I'm Darshil.
I’m a Backend & DevOps Engineer focused on building scalable, reliable, and cloud-native systems using Node.js, NestJS, AWS, Docker, and modern infrastructure practices. Over the last few years, I’ve engineered microservices, automated cloud deployments, built real-time platforms, and worked across distributed systems that emphasize performance, security, and maintainability.
I enjoy solving backend challenges—whether it’s reducing API latency, designing fault-tolerant architectures, implementing queue-based workflows, or building end-to-end CI/CD pipelines. My work often revolves around high-throughput APIs, content-processing pipelines, authentication systems, and large-scale data platforms.
