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. ---------------------------------------------------------------------------------------------------------------- 🔖 Hashtags #php #laravel #webcrawling #datascraping #dataextraction #html #datamining #microsoftexcel #webscraping #curl #json #webcrawler #css #jquery #bootstrap #api #restapi #ajax #docker #linux
