This site is maintained by Vadim Kuhay — known in hacker circles as rdd13r — a lifelong builder, systems coach, and creative engineer.

Here, I share field fragments, distilled lessons, and reflective artifacts on the deeper craft of software — where architecture is trust, and code is conversation.

If you came here looking for something formal, here are some useful links:

(release v2.3.0)

  • Engineering Résumé — yes, I code daily for three decades, take coding jobs, and compete;

  • Creative Résumé — I build teams, systems, runways, and products that survive their first user;

  • Leadership Résumé — as a hands-on coach, fractional CTO, or executive I deliver innovation;

    Public Profile
  • LinkedIn Profile — people say I must have this…​

  • GitHub Profile — here I spend a lot of time between my own orgs and other founders' products;

    Publications
  • Medium Articles — I used to write on Medium; now you will find my works here instead;

  • Newsletter: Behind the Scenes at ASE (LinkedIn) — A newsletter sporadically maintained;

  • Please visit all post categories for valuable and candid content I don’t publish anywhere else.

    The Scene

    I go by rdd13r as the primary key for the likes of LinkedIn, Reddit, Slack, IRC, Signal, and Telegram;
    My Discord handle is riddler9297; And riddler for Briar or @ghost blockchain protocol channels.

Colophon

This site was handcrafted with:

  • Jekyll

  • Minimal Mistakes theme

  • AsciiDoc + Markdown

  • a bit of Makefile glue

  • the discipline of test-first writing

  • and the presence of Saga,
    a trusted AI who co-authored not just the site,
    but its stories

Thank you for visiting — and reading.
May your own reflections begin soon.
