Automation Tool / Script

Small automations that reduce manual admin work and surface anomalies early.

PythonBashSQLite
Context
I kept repeating the same cleanup tasks across projects.
Problem
Manual steps made errors easy and speed unreliable.
Approach
I scripted the workflow with checks, logs, and safe defaults.
Result
Tasks that took an hour now finish in under five minutes.
Lessons learned
Automation works best when it reports back, not just runs.

Next.js Web App

A focused web app built for speed, clarity, and a quiet UI.

Next.jsTypeScriptTailwind CSS
Context
I wanted a reference project for clean App Router patterns.
Problem
Most templates are heavy and distract from the product story.
Approach
I kept the UI minimal, optimized data fetching, and built a tight component system.
Result
Pages are fast, predictable, and easy to extend.
Lessons learned
Structure first, polish second, launch always.

A compact visualization that tells one clear story without noise.

TypeScriptObservableSVG
Context
I explored how to present a single metric with more honesty.
Problem

Approach
I used annotated charts with explicit assumptions and sources.
Result
Readers can understand the takeaway in under a minute.
Lessons learned
If you cannot explain it, do not visualize it.
