Andrei Bondarev is a solutions architect and founder with 11 years of hands-on experience building AI, ML and generative AI systems and scaling remote engineering teams. He has led engineering and product efforts at organizations ranging from NPR and FiscalNote (helping scale an AI-powered product to $40M ARR) to startup and agency roles, and now runs Source Labs while advising as fractional CTO on client projects. Andrei blends deep backend craftsmanship—evident in open-source contributions to Ruby A/B testing tooling—with senior leadership that cuts cloud costs and drives measurable user growth. He frequently architects AI-driven search, automation and compliance platforms and has a track record of shipping both consumer-facing and enterprise-grade systems. Based in New York, he pairs entrepreneurial instincts with a researcher’s background in image processing, giving him a practical but experimentally curious approach to ML problems. He’s available for project engagements and brings a rare mix of product, operational and low-level code expertise.
