Projects

AI platforms I designed and built at Lintryxs, plus learning projects with live demos.

    • Query chat: an answer about credit card limits with numbered source citations and suggested follow-up questions
    • Per-department audit log, with last-24-hour totals and filters by action, resource, user and date
    • Main dashboard with a side menu (documents, queries, members, audit) and role-based access

    Multi-tenant RAG platform

    Question answering over financial documents, with per-page citations.

    Problem
    Semantic search alone missed specific figures, such as the amount thresholds in a policy.
    Outcome
    Four-stage hybrid retrieval (semantic, lexical, RRF fusion and rerank) over ~100K chunks, with streamed answers.

    Management platform with a real-time Kanban

    OKRs, a collaborative Kanban and AI analytics for a financial cooperative.

    Problem
    The cooperative ran its internal operations on scattered spreadsheets and email.
    Outcome
    One platform where managers track OKRs and projects in real time, and AI flags projects at risk.

    AI conversational agent

    From a static menu-based chatbot to an agent that understands natural language.

    Problem
    A credit union's members had to navigate a static menu to get answers.
    Outcome
    The agent answers in natural language in under 2 s and never makes up financial data: if something isn't in its knowledge base, it says so and gives the cooperative's phone number.

    TaskFlow

    Projects and tasks for small teams, with a Kanban board and AI analysis.

    Problem
    Small teams need to organize projects, owners and priorities without the complexity of big tools.
    Outcome
    Teams with roles, projects and a Kanban board with filters and search. Claude summarizes the board, flags risks and suggests next steps, streamed; permissions live in Postgres with Row Level Security.
