Summary
👤
Senior🎓
Top SchoolBartosz Krol is a product-focused engineering leader and founder with nine years of experience building full-stack and mobile products, now based in Berlin. He co-founded ShopAssist to solve search abandonment on Shopify stores using an AI Sales Assistant that boosts AOV and conversions without extra headcount. His background spans startups and large-scale systems—from voice AI and observability at telli (YC F24) to scaling backend services for Riot Games and leading engineering teams at Quantiva. Hands-on across TypeScript, React/Next, Go, Python, mobile stacks and serverless infra, he blends product intuition with low-level engineering rigor rooted in embedded and firmware work early in his career. Known for shipping complex integrations (voice, video, RAG/LLM pipelines, ChimeSDK) and establishing strong QA/observability practices, he thrives where product meets platform. He’s an engineer-founder who still writes production code while shaping product and go-to-market tech.
