Hi, I'm Nebiyou Tesfaye —
I build things that get used.

I build web applications, rank them at the top of search, and turn data into clear decisions — shipping fast with AI in the loop.

01 — About

A developer who likes shipping.

I'm a developer who likes shipping things that people actually use. My work spans custom web and application development, data analysis and visualization, and rapid "vibe coding" — prototyping working software quickly with AI in the loop.

On the engineering side I work across PHP, Python, JavaScript, and C#, and I'm comfortable deep inside content platforms like WordPress, SharePoint, and Drupal — building custom plugins, directories, and integrations rather than just configuring themes. I'm also an SEO obsessive: I've taken policy pages to the top of Google, rebuilt a high-traffic site for sub-2-second loads and clean Core Web Vitals, and tuned enterprise search so the right content actually surfaces. On the data side I turn messy inputs into dashboards and visuals that make a decision obvious — and I lean on modern AI tooling to move from idea to working prototype fast, without cutting corners on correctness.

Projects.

A mix of shipped work and projects in progress, across the three things I do most.

Web & Application Development

Member Intelligence Hub

A WordPress plugin that replaced a four-tab member list with a single search surface. It reads about 800 companies and 18,000 people straight from the association's membership system, refreshes itself every three hours, and adds four public directories plus an analytics view—expertise, geography, and growth all derived from the export itself.

Staff directory for a trade association

Replaced a hand-typed staff page with a plugin: a searchable directory that sorts itself by surname, an admin-only form for new hires, and a spreadsheet import that shows every change before saving it.

Faith-education platform for kids & youth

A ground-up WordPress build for a children's and youth faith-education nonprofit. I hand-coded a custom block theme and brand system, a library of illustrated lesson pages, and an interactive app that surfaces a saint for any day of the year — then added free membership and donations, plus a Grades 1–12 curriculum across twelve sites, each with its own style guide.

Data Analysis & Visualization

Content Freshness Decay plugin

A WordPress plugin that pulls Google Search Console data and scores a "freshness decay" per post — turning a vague content-maintenance chore into a ranked, data-driven queue of what to refresh first.
