What I'm looking for

I'm looking to build production AI systems where retrieval quality, reliable agent behavior, cost efficiency, and low latency matter. I value hands-on ownership from ingestion through deployment, plus opportunities to ship useful AI products at real scale.

At Dapp Mentors and Daltonic LLC, I've architected and deployed RAG systems, multi-agent workflows, and LLM automation for 5,800+ learners. I build the full path from web ingestion, chunking, and indexing to context-aware response generation across web, Discord, and Telegram.

I've built FastAPI backends with Chroma, LangChain, Docker deployment, monitoring, and metrics-driven iteration. My work spans OpenAI, Claude, Gemini, DeepSeek, Ollama, and OpenRouter, with cost, latency, retrieval quality, and predictable agent behavior treated as core production constraints.

I've also evaluated AI training data at AfterQuery AI Lab, built backend systems for ML-driven applications, and shared production AI practices through 45+ articles, 140+ videos, open-source repositories, and the Dapp Mentors community.
