About

As an Elasticsearch SME and Full Stack Senior Engineer, I have over six years of hands-on experience managing large-scale commercial data sets and providing consultancy services. Currently, at BJSS, I work with a diverse range of technologies across two international teams, focusing on securing and upgrading Elasticsearch clusters, developing new strategies to optimize data usage, and exploring AWS cloud architecture for enhanced failover capabilities. Additionally, I support Java Spring Boot server-side solutions and extend client-side technologies, setting up dashboards and metrics to monitor application performance. Previously, I worked at Tesco Bank as a Senior Java Software Engineer, where I was responsible for maintaining and extending web products built on Java 8 and Spring Boot, integrating CI pipelines using Jenkins and AWS, and mentoring junior developers. At the BBC, I led the integration of Elasticsearch with Java microservices and Node applications, enhancing system capabilities through AWS auto-scaling and secure configurations. My extensive experience also includes roles at Reed Business Information, Clydesdale Bank, Barclays Wealth and Investment Management, and JPMorgan, where I developed and integrated Elasticsearch solutions, led Java development projects, and established automated development pipelines. With a passion for learning new technologies and a comprehensive background in software engineering, I am committed to delivering high-quality, scalable solutions.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
