Hey, I’m Rajan—Cloud Engineer, bug wrangler, AWS whisperer, and part-time debugger of my own mistakes. I specialize in serverless architectures, strongly typed code, and pretending my deployments worked on the first try.

I write sturdy (read: mostly functional) code in Python and TypeScript and occasionally flirt with Golang when I feel like questioning my life choices. My hobbies include taming databases, convincing CI/CD pipelines to behave, and playing 4D chess with LLM frameworks like LangChain and LlamaIndex.

When I’m not engineering the cloud, I’m adding and fixing bugs in equal measure, moonlighting as a full-time builder and part-time gamer, and scouring the internet for the best memes to distract myself from production issues.

If you need help with AWS, serverless magic, or just want to complain about TypeScript with me—let’s talk.

Find me on X (@RajanDmr) for a fine blend of tech updates, memes, and occasional existential crisis tweets about serverless pricing.
