What I'm looking for

I’m looking to build reliable backend and AI-enabled products—especially RAG chatbots—where I can own integration-heavy services, collaborate closely with engineering, and continue mentoring teams while delivering high-quality, testable systems.

I’m a Server Engineer focused on backend systems, integration layers, and applied AI. I build production-ready APIs and services, and I enjoy turning research into measurable, working features.

Most recently at Wix, I worked on an AI Chatbot application based on RAG, including context management and generative AI. I handled backend and prompting, performed model research and evaluation, and delivered integration tasks using React/Redux, NodeJS, MongoDB, Jest, and OpenAI/VertexAI.

Previously at NewFire Global Partners, I served as Lead Software Engineer and Senior Software Engineer. I delivered healthcare/social community platform backend APIs, led AQA testing and automation for data/credential management, and contributed architectural design, research/discovery, mentorship, and technical interviews with React/Redux, NodeJS/NestJs, PostgreSQL, Redis, RabbitMQ, and Kubernetes.

Across earlier roles, I developed Node.js backend services for payments and casino/social gaming, handled platform API design and integrations, and supported partial team management as backup for the team lead. I also bring deep Unix experience and a broad data and database background across PostgreSQL, MSSQL, Oracle, and MongoDB.
