Work Experience
Co-founder
2018 - PRESENT
Aetherix Web
- Designed and implemented the architecture for building custom-build websites with just a single click, without any code or database duplication. All the pages load under 0.03s, and the project hosts 1,000+ websites on a 4vCores and 4GB RAM VPS.
- Built an SEO system that auto-creates proper SEO tags for each page based on its type and content and automatically converts images to WebP, helping many clients' websites rank in Google's top results, including the highly desired "position zero."
- Developed and implemented large-scale crawlers and data scrapers with the highlighted features: URLs and data auto-discovery, a crawler crash recovery system, low resources usage. The crawlers are used in WhatPSU.com and Laptop-Finder.com websites.
- Created and executed a supervised AI based on a neural network for solving numeric-based web captchas.
- Coded a managing and timing system for Facebook business pages. It includes automatic creation, timing, publishing of posts, smart templates, and more. For some clients, this Facebook bot replaced the person maintaining the company’s Facebook page.
- Designed and implemented a REST API from scratch used as a back end for a Chrome extension. The API is based on the Yii2 framework with auth. It's very responsive and lightweight as it was designed to serve thousands of users at a time.
- Planned and built a complex Docker-based architecture for a team of six web developers as part of a migration project from VMware-based virtual machines. This DevOps' work goal was to cut costs on the development environment and move to the cloud.
- Implemented an ads system, DJint Ads, for our site-in-click platforms, where an intelligent algorithm is placing advertisements on very subject-diverse websites. I developed the advertiser panel, the statistics dashboard, and the placing algorithm.

WhatPSU
This website calculates the power draw of users' PC for any given CPU, GPU, or both, and suggests the best PSU. It would also advise on links for buying the recommended PSUs from the industry-leading brands, filtering them. All CPU and GPU models are fetched and updated regularly using web crawlers to scrape data off the web.
I was the technical lead, architect, and senior full-stack developer, working on this project from scratch with another full-stack developer. Thanks to my SEO work on this website, it is ranked as the top result in Google for popular queries like “PSU for Intel 11900k”. It is also ranked first for even more popular and general queries like “3070 ti power supply” and “3080 ti power supply.”

DevOps: Migrating a Development Environment to Docker
I designed and implemented a complex Docker-based architecture for a team of six web developers as part of a project to migrate the workstations from VMware-based virtual machines with PhpStorm—a VM for each developer—to Docker. The goal was to cut costs on the development environment and move to a cloud environment.
The original structure was deployed on dedicated servers that needed to be upgraded every other year and was very expensive to scale for new developers who joined the team.
The new architecture consists of:
• Apache, PHP, and MySQL custom-built stack
• Six code-servers on custom-built containers
• A local Git container
• A Twingate container (instead of VPN)
This new architecture utilizes Docker’s volume-mounting capability to share each developer’s work folder with the Apache server. I chose Twingate instead of VPN to limit the bandwidth usage of the cloud and to secure access to the source code.
As a result of this migration, we were able to run everything on a light 2-core, 4GB RAM server with enough resources left to spare for future scaling, which saved a lot of money and boosted the developers' productivity as it is faster, more stable, and more secure.
