Vinayak Ajith

Agents, retrieval, and eventually robots.

I'm an AI/ML engineer. I build agents that work on a company's real data (its databases, email and documents) and answer with numbers you can check.

Now

OptiFlow, at Dellizo

OptiFlow is an AI analyst that runs on a company's own servers. You connect the databases, email and documents once, then ask questions in plain English. It writes the queries, reads the relevant threads, and answers with numbers that trace back to the query that produced them. When it doesn't know, it says so.

I built it end to end: the agent architecture, the email research subagent, the retrieval layer and the front end.

Focus right now: agent memory, hybrid retrieval and reranking, and OS internals for matter-os.

Work

  • matter-osearly

    An experimental AI-native operating system on a custom RISC-V kernel.

  • mnemo

    A personal AI companion with long-term memory. It keeps facts and notable episodes across conversations and ranks them by relevance, recency and importance.

    Python · pgvector · Mem0 · Claude

  • autonomous-research-agent

    Researches a topic end to end: searches the web, reads PDFs, keeps its own state, and writes a structured summary. Runs on a local model.

    LangGraph · Tavily · Llama 3

  • Hierarchical emotion classifierexperiment

    130 emotions arranged as a feelings wheel, three levels deep. Masking keeps each prediction consistent from broad to fine, with a consistency loss and focal loss for the rare classes.
