Overview

I work across the whole stack: the dashboard, the Go backend behind it, and the data pipelines that feed it.

What I built

  • Frontend

    • Primary developer of the wealth management dashboard: portfolio, holdings, accounts, instruments and bond views, in React, TypeScript, TanStack Query and Tailwind CSS.
    • The statement import screens: upload a statement, review the staged entries, then commit them.
    • The investment policy statement (IPS) wizard.

  • Backend

    • Contributions to the Go backend and its API reference.

  • Data

    • Designed and built the market data pipelines: mutual fund NAVs, exchange prices and corporate actions, security identifiers, benchmark indices, regulatory registries and fund disclosures, in Go, Bash and Python on PostgreSQL.
    • Monitoring and alerting for every pipeline, and data quality audits with reviewed, reversible repairs.

  • Quality

    • Playwright end to end tests, accessibility fixes, verification in the browser and AI assisted review workflows.

Fig. 1 Where my work sits

Market data flows through pipelines I built in Go, Bash and Python into PostgreSQL, through the Go backend I contribute to, into the dashboard I built. Imported statements land as staged rows on screens I built and are committed only after review.

Key decisions

  1. D-01

    Nothing is committed blind

    Imported statements are staged and reviewed before they're committed.

  2. D-02

    Repairs can be undone

    Data quality fixes are reviewed and reversible.
