Summary
👤
Senior🎓
Top SchoolJulia Passynkova is a Staff Software Engineer based in Toronto with 20+ years of engineering experience and a decade focused on full-stack and AI-driven systems. She builds AI-native applications that blend LangChain, LlamaIndex, CrewAI and modern React ecosystems with cloud platforms like AWS and GCP to deliver RAG, agentic workflows, and LLM-powered user experiences. Her background spans enterprise fintech and trading systems—real-time pricing engines, RFQ platforms, and workflow automation—so she brings production-grade reliability and scalability to experimental AI projects. As founder-consultant at SmartByte she prototypes practical AI products (e.g., flyer-parsing grocery intelligence, fine-tuned embeddings, multi-agent automation) and documents work on GitHub. Notably, she combines deep legacy systems experience (Java, distributed services, message buses) with modern ML toolchains, enabling tight integration of model reasoning into mission-critical apps. She pairs strong hands-on implementation skills with an uncommon emphasis on evaluations and metrics for model grounding and UI-driven agent behavior.
