SUMMARY

PHP developer with evidence of development and support for web add-ons, CRM systems and a solution
for business automation.

My main specialization includes PHP, MySQL, JavaScript, REST/SOAP integration and working with legacy
codebases. I have experience supporting and extending existing projects, implementing new business
features, optimizing SQL queries, integrating third-party services, and troubleshooting complex production
issues.

I am most interested in remote work opportunities, long-term project support, and feature development for
existing products. Comfortable working independently, exploring unfamiliar codebases, and solving
production problems.
