PROFILE
I have over 5 years of professional experience in PHP development, specializing in Laravel, with
strong experience in both outsourcing and product-driven environments. I have led backend
development for multiple commercial projects from scratch, owning system architecture, API
design, database structure, and third-party integrations.
I have hands-on experience with Node.js and asynchronous processes, as well as integrating and
maintaining a wide range of external services. My expertise includes implementing complex
payment systems using Stripe, PayPal, FastSpring, Paddle, PaySession, and Cryptomus, focusing
on security, reliability, and scalability.
In a product company, I worked on a high-load platform serving 200,000+ users, built with
Laravel, Angular, PostgreSQL, and ClickHouse. I contributed to developing and optimizing
complex business logic, improving system performance, and handling large-scale transactional
and analytical data. I actively participated in architectural decisions and cross-team collaboration
to ensure stability and long-term scalability.
I also mentor junior developers, conduct code reviews, define best practices, and contribute to
technical decision-making. I focus on delivering clean, maintainable code and building robust
solutions that provide measurable business value, while continuously improving my skills and
staying aligned with modern backend and product development practices.
