This is me.
Hi, I'm Darshil.
I'm a Software 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.

Scaling Beyond Limits: How Amazon ECS + Queues Supercharge High-Frequency Automation
In today’s world of fast, reliable, and scalable applications, user experience is everything. Platforms like YouTube handle millions of uploads daily without making users wait — and the secret lies in event-driven task automation, powered by Amazon ECS and message queues such as Amazon SQS. In this blog, we explore how you can design similar systems to automate heavy workloads, process tasks asynchronously, and optimize performance — all while reducing latency for the end user
