## About

```text
As an independent software developer, I build websites and applications for project requirements, along with WhatsApp bots using Meta Business APIs and WhatsApp Web.js. I also integrate external services to connect applications and automate processes.

At Software Testing Bureau, I developed automated web interface and regression tests using Selenium with Java, Appium, and WinAppDriver. My automation reduced validation time from as much as three days to about five hours.

I also developed a web form automation flow that uses OCR to extract information, processes it through the OpenAI API, and helps fill in web forms. At Software Testing Bureau, I also supported the Stela tool and installed and configured solutions on Windows and Linux servers.

In my personal development and AI lab, I experiment with web pages, SaaS prototypes, and AI integrations using JavaScript, Node.js, React, Express, Ollama, and Claude Code. I hold a technologist qualification in software analysis and development and a technical qualification in software development.
