- Independently prototyped a RAG GenAI chatbot to assist users in navigating internal documentation, demonstrating self-initiative and commitment to self-education by acquiring relevant skills and knowledge through independent research and experimentation.- Redesigned and led team to rebuild LLM Gateway with load balancing, authentication, and rate limiting for model inference. Redesign allowed team to support new models 80% faster and with no code changes.- Designed a model discovery service to allow LLM gateway to automatically know when models are on/offline. New models are discovered when new Kubernetes clusters and model deployments come online. Eliminated the need to maintain a long static list of model servers that constantly needed updating.- Created an automated login tool using Selenium and Java to streamline end-to-end testing processes, enabling production-like flow for testing.- Collaborated with our team lead to provide leadership and direction to a team of four senior engineers. Guiding them in making informed decisions regarding feature development and implementation strategies.- Assisted teammates in understanding our tech stack to empower them in building and debugging issues more effectively. Which led in fostering a collaborative and knowledgeable team environment.- Diagnosed and resolved complex intersystem issues to maintain the stability and reliability of our technology stack. Often involving tracing through proxies present in the networking stack and logic errors present in dependent up/downstream systems.- Developed a microservice deployed on Kubernetes that integrates with our unique policy service, api gateway, and security service for providing authorization for our microservices in cloud environments.
