Zephry is a full-stack cloud developer, dedicated to building browser-based web apps. On the front-end we concentrate on multi-page web apps (MPA) built by hand with HTML5, ES (JS) and CSS3. For visualization document manipulation, we make heavy use of the excellent d3.js library.
On the backend we deploy two main stacks:
- Linux, Nginx, Golang & PostgreSql (or Mysql) as REST services for front-end JAM-stack applications.
- Windows, IIS, C# & Sql Server for corporate Windows installations using Asp .NET Core REST services behind JAM-stacks (or MVC on demand).
This site is an example of a static JAM-stack multi-page frontend and a decoupled Golang REST service running on Linux, NginX and Postgres.
A major drawcard of any site is its graphical content. Just reading reams of text (like this!) is a huge put-off. And not any graphics will do. One can stomach only so many emojis before subconsciously discarding them. The same goes for photos of stuff one has no interest in. But presenting your dry information in big, colorful, transforming visuals is something else entirely! Zephry uses ES6 and D3.js to impressive effect.
Map Topography is simply a specialized area of data visualization, concerned specifically with geographic features in a standard coordinate space. The map of the world, commonly portrayed in modern websites, is a typical example. This kind of visualization should not be confused with raster images of maps (gif, png and jpg files). Instead, they are typically rendered as svg or canvas DOM components, and as such can be styled and manipulated in the same way any DOM element can.

This site is what is known as a JAM-Stack site. Like plate-cakes, with syrup between them... Who knows why tech things get weird names? Anyhow, it basically means that the site is a "static" one, entirely independent of a home server to feed it content. It gets its content from a foreign source (or sources) and renders its pages on the fly. It uses (J)avascript, to fetch content from an (A)pi and render it with (M)arkup. Get it? (J)(A)(M)? Nudge-nudge... The API in question feeds the site with JSON formatted data.
