About

Who builds Blinkimg: ten years of shipping, and one engine I wrote

A decade of client work, a degree, a certification, and one image engine written end to end.

I publish a number only when the engine has produced the file behind it, so every figure on this site can be re-run.

I am a full-stack software engineer. I have been building for the web since 2016, more than a thousand sites, with WordPress at the centre of the work. What I do best is turn an idea into a working web product: the code, the data and the page.

On Blinkimg I build all of it: the engine, the workers, the API and the pages. I also teach programming on DevsDemy, on Udemy and at Sahadat.dev. Everything the site publishes about a file, it can reproduce on demand.

Expertise

What I can be held to

Five areas, and where each one shows.

  • Every benchmark on this site

    Image formats and encoders

    JPEG, PNG, WebP, AVIF and HEIC end to end: the encoders, the quality ladders and the byte-target search behind Blinkimg.

  • WPManageNinja, since 2022

    WordPress at scale

    More than a thousand sites since 2016, and Web Developer III on the team behind the Fluent plugins.

  • In development

    Mobile apps

    Developing mobile apps now, from the same full-stack base as the web work.

  • 16.3K subscribers

    Teaching web development

    16K+ students through DevsDemy, Udemy and Sahadat.dev, still teaching weekly.

  • Sources and settings are public

    Measurement you can re-run

    Every figure comes from a build step that runs real images through the engine and writes the result into the page.

Editorial standards

How I write and test what I publish

Three rules a reader can check on any page of this site.

  • Figures

    A number is a file

    Every size on the site comes from a build step that runs real images through the engine and writes the results into the pages. None is typed from memory.

  • Limits

    The better tool is named

    Tool pages carry a section on when to use something else, and they name what to use instead, ours or not.

  • Changes

    An edit is dated

    When a post changes after it goes out, it shows the day it changed beside the day it was first published.

The method behind every figure is on how we measure.

Also mine

Three products I build and run

Same engineer, same standard for published numbers.
