Hi, I'm Nebiyou —
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

Associate Members directory plugin

A custom WordPress plugin (v2.3) powering a searchable, paginated member directory for a professional association — four member-type shortcodes, button-triggered search, custom pagination UI, and parameterized, injection-safe queries.

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.

Web & Application Development

Corporate intranet build-out

Converted a set of corporate intranet mockups into seven clean, standalone, responsive front-end pages using CSS Grid and a cohesive navy-and-bronze palette — handoff-ready and consistent across screens.

Nonprofit education website
