PHP developer with approximately 3 years of commercial experience in
the development, maintenance, and optimization of web applications. I
have experience working with PHP-based frameworks, REST APIs,
third-party service integration, front-end technologies, and database-driven
applications.

I am proficient in AI-powered development tools, including:

● Claude Code
● OpenAI Codex,
● Gemini CLI
● Figma Make,

which I use to optimize development workflows and boost productivity.

I have also worked without using AI.

I have experience collaborating with designers and developers to
implement new features, improve existing applications, and create easily
maintainable solutions for projects of varying complexity. I am open to
feedback, technical discussions, and continuous learning.

During this time, I have completed projects of varying levels of
complexity. I always deliver high-quality work in accordance with SOLID
standards and other programming principles. I am open to discussion and
any constructive criticism.
