About
12+ years of experience in full-stack development and system architecture, specializing in building production-ready digital products with a strong focus on speed, scalability, and execution quality.
My core expertise lies in PHP-based ecosystems, including Symfony, Laravel, and Joomla. I have delivered a wide range of production systems, including CMS platforms, API-first architectures (REST & SOAP), complex data models, and enterprise-grade backend solutions across MySQL, MariaDB, MSSQL, and PostgreSQL.
On the frontend side, I focus on fast, clean, and performance-oriented interfaces. I work with modern JavaScript frameworks and structured UI patterns, always prioritizing usability, performance, and maintainability.
In recent years, my focus has shifted toward product-driven engineering, CRM integrations, automation-heavy workflows, gamification systems, and SEO combined with AI-driven visibility strategies. I build systems that are not only functional but also optimized for growth and operational efficiency.
I actively work in AI-augmented development environments, using tools like Cursor, Gemini CLI, and automation platforms such as n8n to significantly increase development speed and reduce iteration cycles. This enables rapid idea-to-production workflows without compromising engineering discipline.
Beyond development, I have strong experience in infrastructure planning and technical operations. I design and maintain reliable, secure, and cost-efficient systems while aligning technical execution with business continuity, performance, and scalability goals.
I value structured thinking, clear communication, and product-focused engineering. My approach combines fast execution with strong architectural awareness, ensuring that systems remain maintainable and evolve sustainably over time.
