I ship AI that earns its keep — zero-LLM heuristic supervisors, hybrid RAG with BM25 reranking, and multimodal clinical pipelines. Latency-obsessed, source-grounded, readable at 2am.

— 01 / About

Engineer, scientist, researcher — in that order on Mondays.

04years of focused practice

I build retrieval-grounded AI systems that are honest about what they don't know — and fast enough that you don't notice the work underneath.

I'm an AI Engineer, Data Scientist, and Researcher focused on retrieval-augmented systems, multi-agent architectures, and applied machine learning. I have shipped commercial AI products across travel, healthcare, Islamic education, and B2B matchmaking — and published peer-reviewed work in computer vision and optimal control. I care about source-grounded outputs, latency budgets, and code that other engineers can read at 2am.

# retrieval pipeline I actually ship
retriever = HybridRetriever(
    dense  = ChromaDB(k=20),
    sparse = BM25(k=20),
    rerank = FlashRank(top_k=5),
)

Betopia AI Products

A connected AI suite for model access, AI workspaces, platform operations, and AI-assisted software development.

Betopia AI Products1 / 6

Betopia AI Products is a connected suite for the full AI-product lifecycle: access, creation, governance, and development. The Developer Platform gives teams one workspace for model discovery, API keys, usage analytics, request logs, and OpenAI-compatible integration examples. Platform Admin gives operators the controls to manage users, providers, limits, feedback, and live platform health. Betopia Chat and Chat Admin pair an AI workbench—with streamed chat, Deep Research, image generation, files, Knowledge Base context, and artifacts—with the administrative controls for moderation, spend, RAG operations, SSO, memory, and system health. Betopia Coder completes the suite with a terminal-first agent and a desktop app builder for inspecting, editing, running, and iterating on local projects. I contributed across these products, translating complex AI and operational workflows into clear, dependable interfaces.
