I am a highly experienced Software Engineer specializing in designing and developing robust, high-performance back-end systems. With over 15 years of dedicated experience in the IT sector, I excel at building and scaling complex applications in high-traffic environments. My expertise is centered on driving business value through technical solutions, particularly within the Affiliate and Partner domains. Architecture & Development: PHP (up to 8.3), MySQL, PostgreSQL. Designed and maintained high-throughput RESTful microservices. Performance & Scalability: Successfully optimized database query and storage efficiency (30% improvement) to handle demanding traffic loads. System Ownership: Led the full development lifecycle for critical systems, including audit-proof Financial Closure platforms and high-adoption Partner Fast Payout features. Key Strengths: I am proficient in modern SDLC practices, including CI/CD workflows (Docker, Jenkins, PHPStan) and Agile methodologies (SCRUM/KanBan). I proactively leverage advanced development tools (AI assistants, PhpStorm plugins) to maximize code efficiency and accelerate project delivery. Currently, I am actively seeking a challenging Senior Software Engineer role where I can apply my deep experience in building resilient, data-intensive web applications.
