What I'm looking for

I seek roles focused on automation and scalable backend systems with strong CI/CD culture, collaborative teams, and opportunities to apply LLMs and performance optimizations.

I am a Senior Software Engineer with hands-on experience in automation, backend systems, and CI/CD, currently working in modem and software-automation domains. I focus on delivering scalable, efficient systems that reduce developer load and optimize resource usage.

At Samsung Semiconductor India Research, I built an LLM-driven GTest generation pipeline integrated into CI/CD, and redesigned a JIRA data replica reducing memory usage by 75% while improving API sync performance twelvefold.

I have implemented secure, approval-based data sharing tools and browser-extension driven automated download systems that handle hundreds of transfers and dozens of daily requests, leveraging Python, Selenium, NoSQL, and content-addressable storage.

I enjoy contributing to open-source, solving algorithmic problems, and applying emerging technologies such as LLM API integration and prompt engineering to practical automation challenges.
