About Me
I'm a Senior Backend Engineer with over 8 years of experience designing and building scalable, cloud-based products using TypeScript, Node.js, AWS, and GCP. Today I'm focused on AI-powered products, LLM applications, and conversational AI workflows that solve real business problems.
I integrate OpenAI and Claude into production systems, and I've collaborated on building an AI chat and its tools on top of the backend services and data pipelines that feed them. My foundation in microservices, serverless, and event-driven architecture is what lets these AI features run reliably at scale.
I've worked remotely with early-stage startups in New York and San Francisco, collaborating directly with founders and cross-functional teams to turn product requirements into reliable, high-impact solutions. I also bring technical leadership, mentoring, and engineering hiring experience.
Currently seeking contractor opportunities with product-based companies, especially AI-powered products. Let's build something great together! 🚀
