About Me

I'm Mayank Raj, a Software Engineer with 4+ years of experience designing and shipping scalable backend systems and cloud-native applications.
Currently at CommentSold, I build automation systems for the ECHO platform — webhook-driven social media integrations, comment-triggered auto-replies, and AI-powered DM workflows running on AWS serverless infrastructure (Lambda, EventBridge, CloudWatch) provisioned with CDK.
Previously at Sarv.com, I engineered real-time collaborative applications and high-traffic microservices using Node.js, TypeScript, Redis, and RabbitMQ. At Quantela, I contributed to enterprise API monitoring and event-driven systems.
I focus on system design, debugging complex production issues, and building reliable automation pipelines that scale.
