1 Programming Achievements
==========================

  - Website builder: I created a website constructor somewhat similar to
    MediaWiki.  See www.chalaev.com for more information.
  - Dynamic web pages: I wrote DB.js - tiny (5.8k) and fast JavaScript
    library for creating dynamic web pages, see
    <http://db.leanws.comdb.leanws.com>.
  - Fully automated website testing: I can test websites fully
    automatically by modelling human behavior, saving screenshots and
    web pages code and comparing the latter to templates.  See the video
    link on www.chalaev.com


2 Tools
=======

  - Ruby on Rails 2022-2026: dental insurance website.
  - Common LISP + Clojure: (i) LISP for website back end in 2020-2022,
    (ii) Clojure for 10% website back end in 2022-2026, (ii) LISP code
    generating dental provider catalogues in 2022-2026.
  - Dynamic web-development: I used KnockoutJS in 2017-2020, later
    replaced it with my own code, see <https://db.leanws.com>
  - PostgreSQL: Worked with big tables containing info about numerous
    healthcare providers and members. Sometimes I updated long (150+
    lines) SQL queries.
  - GNU/Linux + SHELL: I use linux since 1999, and I can configure a
    Debian server (nginx, exim4, dovecot, PostgreSQL, systemd).
  - Perl: I used Perl for fully automated website testing. See also my
    wifi-switcher: <https://github.com/chalaev/wifi-switcher>
  - C++: I used it during my University career for numerical
    calculations. Simple classes, no advanced features.
  - Python and AI: In 2017-2020 I used Python to power back end of a web
    server. In 2025 I used it for "AI Dojo" AI course provided by the
    UHG. As a final test assignment, I wrote python code for medical
    claims' adjudication.
