    Labour & Payroll Compliance Copilot

    Live · Vietnam

    A compliance copilot for the one person who wears every hat at a 10–50 person Vietnamese company — HR, ops, and payroll at once.

    Checks payroll, BHXH, personal income tax, contracts, and overtime against current Vietnamese labour law, then explains what is wrong and how to fix it — in Vietnamese. Built for the reality that most SMBs here cannot afford a compliance specialist.

    Open AML & Transaction Monitoring Platform

    Open source · self-hosted

    Compliance operations infrastructure a bank can actually run on its own infrastructure: real-time transaction monitoring, sanctions and PEP screening, and one case manager to investigate what it flags.

    My work is the product and console layer — the detection navigation, the case-management workspace, and an AI triage copilot that proposes a disposition with its rationale and evidence rather than a bare score. Demoed against a Vietnam-market scenario with Travel Rule and STR-derivation flows.
