Jewel Nguyen

An operator who builds — turning back-office problems into systems that run themselves.
Showcase · Selected Builds

Things I built because the manual way annoyed me.

Each one started as a personal annoyance and ended as a repeatable system. Some live, some portfolio.

The Builds

Three systems, in production or portfolio
Knowledge · Live

Second-Brain / Life-OS

Telegram capture → markdown vault → styled daily brief. A personal pipeline that turns scattered inputs into one searchable system, with a morning digest that reads it all back.

Python · launchd · Telegram bot · Obsidian

Finance Ops · Portfolio

Contract-to-Order Pipeline

Reads signed contract PDFs, verifies the counterparty across public registries, and drafts the sales order — collapsing thirteen manual steps into a single human review.

Reliability · Live

The Self-Auditing Dashboard

A morning chief-of-staff that reads yesterday's work, checks every automation ran, surfaces conflicts and drift, and pings only when a human decision is needed.

How These Get Built

The pattern behind every project
01 · Scope

Find the leak.

Map the manual steps and lost context before writing a line of code.

02 · Build

Smallest system.

One automation that removes one step, wired into existing tools, documented to hand over.

03 · Run

Make it self-watching.

Schedules and alerts that only fire on failure. Silence means healthy.
