I scrape the “unscrapable.” I automate the repetitive. I build systems that run themselves. Before I touch the code, I dig into the problem. Most scraping and automation jobs fail because someone skipped the research phase. I don’t. Web Scraping & Data Extraction • Handling complex anti-bot protections (Cloudflare, DataDome, PerimeterX) • Browser fingerprinting and stealth automation • Large-scale extraction across millions of records • E-commerce price monitoring • Proxy rotation and CAPTCHA solving Browser Automation • Selenium, Playwright, nodriver • Daily scheduled tasks (logins, form submissions, data collection, reporting) • Headless and headful workflows depending on what the site demands • Long-running automations that survive site changes Automation & Scripting • Business process automation • Scheduled tasks and cron jobs • Data pipelines and ETL • Custom scripts that fit your actual workflow WordPress & WooCommerce • Custom plugin development, including plugins published on WordPress for clients • Recent client work: ShopWriter, an AI content generator plugin for WooCommerce • Data import/export scripts • Product feed automation • WooCommerce ↔ Shopify migrations Chrome Extensions • End-to-end extension development (Manifest V3) • Backend integration with FastAPI and REST APIs • Live example: Bazenda for Chrome, my own extension on the Chrome Web Store Backend Development • Python, FastAPI, PHP • PostgreSQL, MySQL • REST API design I also build complete systems from scratch. Bazenda is the clearest example: a US fashion discovery app I built solo, with visual search, AI recommendations, and price tracking across dozens of brands. Live on iOS, Android, and Chrome. One thing I won’t do is tell you what you want to hear. If your project isn’t a good fit for me, or if there’s a simpler way to solve it, I’ll say so upfront. Saves both of us time. Message me with your project. I’ll take a real look and give you an honest answer.

I build and integrate backend APIs using C#, ASP.NET Core Web API, SQL, PostgreSQL, and REST-based services. I can help with third-party API integration, REST API development, backend bug fixes, database-connected endpoints, authentication-related tasks, Swagger/OpenAPI documentation, and API testing. My portfolio includes an ASP.NET Core Weather API Wrapper with external API integration, Redis caching, standardized error handling, Swagger documentation, and HTTP resilience policies such as retry, timeout, and circuit breaker. I also have an e-commerce API project using ASP.NET Core, Entity Framework Core, PostgreSQL, JWT authentication, and Docker Compose. Services I can help with: • ASP.NET Core Web API development • Third-party API integration • REST API design and implementation • SQL / PostgreSQL backend work • JWT authentication • Swagger / OpenAPI documentation • API testing and debugging • Backend maintenance and bug fixing I focus on readable code, practical implementation, and clear communication.

Title: Golang Backend Developer | Cybersecurity Enthusiast | "One API to rule them all" Hello! I'm a Backend Developer and a Computer Engineering student at Karabuk University. Think of me as the Gandalf of your server—ensuring that malicious attacks "shall not pass!" while delivering secure, scalable, and production-ready solutions.My primary weapon of choice is Golang, specifically working with Fiber and GORM. Whether it's building high-performance RESTful APIs , managing complex SQL databases like PostgreSQL and MySQL , or handling lifecycle deployments on VPS environments, I love crafting efficient systems from the ground up.But I don't just build things; I know how to break and secure them. As an active member of the Siber Vatan Yavuzlar Team , I have a solid foundation in network fundamentals , OWASP Top 10 vulnerabilities , and even malware analysis. During my backend internship at BG-Tek, I also gained hands-on experience configuring pfSense firewalls and developing plugins. What I Bring to the Table: Backend Mastery: Results-oriented development using Go (MVC Architecture) alongside knowledge of PHP, HTML, and JavaScript.DevOps & Infrastructure: Proficient in containerizing applications with Docker , managing Nginx reverse proxies , and utilizing AWS fundamentals.Data Extraction & Security: Highly skilled in web scraping and analyzing web application vulnerabilities to keep your data safe.AI-Driven Efficiency: I heavily leverage AI tools like Cursor and Gemini to optimize algorithm development, design complex SQL queries, and ship code blazingly fast. Recently, I built a complete Accounting & Inventory Management Panel ("Cadının Evi") from scratch, utilizing GoFiber, GORM, PostgreSQL, and Docker.When I'm not coding or hunting for vulnerabilities, you can find me playing computer games, strumming my guitar, or re-watching "The Lord of the Rings" series. I am a native Turkish speaker , fluent in English , and currently leveling up my German (A1).If you need a developer who writes clean code and takes security seriously, let's connect and build something epic together!
