Wordpress / Woocommerce / Shopify / Magento:
* As I work with highly complex fields such as machine learning and quantum computing, working with these CMS platforms has become relatively straightforward for me. *
With over 13 years of experience on magento/shopify and 14 years on wordpress/woocommerce, I am confident in my ability to meet all your requirements. I am capable of handling all aspects of these CMS platforms. I have developed several highly complex WordPress/WooCommerce websites using Elementor, some of which required over a year to complete. Kindly review the "In Progress" section of my profile to view my ongoing projects. As I work with highly complex systems such as machine learning and quantum computing—which require rigorous mathematical reasoning, deep abstraction, and advanced problem-solving—CMS platforms have become straightforward for me due to the comparatively lower level of complexity and predictable architecture they involve. My experience and skills make me distinctive.
Page speed optimization skill (Wordpress / Woocommerce / Shopify / Magento):
With over 13 years of experience in WordPress programming and speed optimization, I can boost your site’s performance to achieve 100% scores, sub-1-second load times, and green Core Web Vitals for both mobile and desktop on Google PageSpeed Insights and GTMetrix. My optimization efforts will make your website load at the fastest possible speed, typically under one second. Additionally, I address Core Web Vitals issues, including Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS), as reported in Google Search Console.
Website speed is influenced by both the web server and website content. As an advanced-level programmer with expertise in complex systems such as Magento and Python machine learning, I optimize both the website and the web server using my extensive knowledge. This advanced-level expertise is crucial for achieving the fastest possible load times for your website.
On-site SEO & Security:
Experienced in WordPress on-site SEO, improving rankings, traffic, and performance through keyword research, meta optimization, schema, internal linking, and speed optimization.
Skilled with Yoast SEO, Rank Math, and custom solutions for complex sites. I also ensure strong security via server hardening, firewalls, malware protection, and secure authentication.
I integrate SEO, performance, and security to achieve lasting gains in Core Web Vitals, rankings, and conversions.
Machine Learning and Quantum Computing:
Over the past six years, I have been deeply engaged in the fields of machine learning and quantum computing. My passion for mathematics and physics, however, began in childhood and has driven a lifelong pursuit of knowledge in these areas. This strong foundation has enabled me to develop advanced expertise in both machine learning and quantum computing.
Decision-making and problem-solving sill:
Decision-making is a critical yet often overlooked skill in website development, essential at every stage—from selecting CMS, themes, plugins, and servers to implementing efficient PHP, CSS, HTML, and JavaScript for optimal performance and SEO, as well as solving development challenges.
With over 15 years of freelance experience, I have seen many poorly built websites caused by suboptimal decisions. Alongside my strong programming background, I am also advancing my knowledge in physics and mathematics, which enhance analytical thinking, problem-solving, and decision-making.
