I am a Senior PHP Developer with 13+ years of experience, building stable, scalable backend systems for real-world production applications. My core expertise is PHP (Laravel), and I also specialize in web scraping, crawler systems, and payment integrations.
I’ve worked on long-term projects involving business systems, APIs, databases, as well as large-scale crawlers for data extraction, monitoring, and automation.
I have solid experience with payment systems, including Stripe integration, subscriptions, webhooks, and secure payment workflows. I approach payment-related features with a strong focus on correctness, security, and reliability.
For crawler projects, I handle real-world challenges such as pagination, rate limits, proxy rotation, IP blocking, and anti-bot protections. I build crawlers that are designed to run reliably over time, not one-off scripts.
I enjoy working in a focused, flow-driven coding style, valuing clarity over complexity. I write clean, maintainable code and care deeply about performance, security, and long-term maintainability.
What I can help you with:
PHP backend development (Laravel)
Web scraping & crawler systems
Stripe & payment integrations
Data extraction & automation
API development & system design
Long-term maintenance & optimization
If you’re looking for a senior-level developer who can own complex backend systems and deliver calm, reliable results, feel free to reach out.

I’m especially interested in projects where AI is not just a “nice feature,” but a real part of the product: reducing manual work, improving search and decision-making, automating workflows, or helping users interact with complex data more easily.
If you’re building an AI-powered SaaS, internal automation tool, RAG system, chatbot, OCR pipeline, or MVP that needs both strong AI thinking and full-stack execution, I’d be happy to help you turn it into a reliable product.
