John Nathaniel Marquez

I'm a dedicated full-stack web developer and data extraction specialist who began my professional coding journey in October 2024. Despite being new to the field, I've demonstrated exceptional productivity with 1,452 GitHub contributions in just 4 months, showcasing my commitment to continuous learning and rapid skill development.

Website Development Expertise:

I specialize in building modern, responsive web applications using cutting-edge technologies. My portfolio includes the MinRights AI platform - a sophisticated oil & gas data management system built with Next.js 14, React 19, TypeScript, and Mantine v7, featuring 87+ integrated technologies. I've also developed the T1NKER PC Rental Management System, a full-stack real-time application with Electron kiosk integration, Supabase backend, and comprehensive admin dashboard functionality.

My website projects demonstrate proficiency in creating business solutions like restaurant management systems, e-commerce platforms, and corporate websites. I excel at translating complex business requirements into clean, scalable applications with modern UI/UX design principles.

Advanced Web Scraping Solutions:

My scraping expertise sets me apart in the data extraction field. I've built the MinRights Regulatory Platform, a sophisticated multi-state government data scraper that processes regulatory information across Colorado, Wyoming, North Dakota, and New Mexico. This system achieves 7,799+ records per second using advanced techniques including ScrapingBee API integration, OCR capabilities for PDF processing, and intelligent anti-detection measures.

I also developed the MyProtein Product Scraper, featuring JavaScript rendering with Selenium WebDriver, dynamic content handling, comprehensive data validation pipelines, and smart pagination systems. My scraping solutions incorporate production-ready features like retry logic, rate limiting, data deduplication, and robust error handling.

Technical Stack:

• Frontend: React 19, Next.js 15, TypeScript, Tailwind CSS, Mantine
• Backend: Node.js, Python, FastAPI, Flask, PostgreSQL, Supabase
• Scraping: Scrapy, Selenium, BeautifulSoup, ScrapingBee, OCR processing
• Tools: Git, Docker, Electron, AWS, Vercel

What Sets Me Apart:

My rapid learning ability, intensive development pace, and focus on production-ready solutions make me an ideal partner for both website development and data extraction projects. I combine modern development practices with practical business solutions, ensuring deliverables that are not only technically sound but also commercially viable.

I'm passionate about leveraging technology to solve real-world problems and am ready to bring this expertise to your next project.
