Shared Intelligence
Practical lessons from building ML systems that scale.
馃憢 Hi, I'm Slava!
I鈥檓 a Machine Learning Engineering Tech Lead II at HubSpot with 10+ years of experience shipping production AI systems across embeddings, recommender systems, LLM-powered applications, forecasting, churn detection, scam and fraud prevention. Right now I鈥檓 building Embedding Hub on top of Qdrant and establishing a Context Layer that helps AI agents stay grounded, efficient, and compliant.
I lead cross-functional ML teams, mentor engineers, and partner with product, data, and go-to-market stakeholders to launch customer-facing AI features worldwide. I thrive at the intersection of infrastructure and product鈥攐wning the roadmap from data pipelines and model lifecycle to agent orchestration, evaluation, and safety guardrails.
Day to day, I stay focused on embedding systems, retrieval quality, LLM evaluation, and agentic workflows鈥攅xperimenting with Google ADK, FastMCP, LlamaIndex, LangGraph, CrewAI, and SmolAgents to push new ideas into production-ready form.
I write here about practical aspects of developing LLM applications and AI agents, and I stay active in the broader community through mentorship and knowledge sharing.
Check out my experiments on GitHub: github.com/slavadubrov.
If you're exploring LLM-powered products, agent frameworks, or robust ML platforms, let's connect鈥擨'm always happy to swap ideas.
