What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and growth in AI and cloud technologies.

I'm Jilson Joseph, a software engineer with over 8 years of industry experience in designing and developing fault-tolerant cloud-native applications. My expertise lies in integrating large language models (LLMs) and AI workflows into production environments, building data ingestion pipelines, and creating low-latency AI inference systems. I have a strong background in using technologies such as Java, Python, AWS, GCP, and Azure, which allows me to deliver scalable solutions that meet the demands of modern applications.

Throughout my career, I have successfully led various projects, including the development of a highly available tier 0 search service at Walmart Global Tech, where I implemented performance testing and designed architecture for synchronizing Elastic Search clusters across regions. My contributions have resulted in significant cost savings and improved efficiency in processes, such as reducing human intervention in trade confirmations by 96% during my tenure at EPAM Systems. I am passionate about leveraging technology to solve complex problems and drive innovation in the software development landscape.
