I am more experienced and established on other freelancing platforms. - 15 years in web development (PHP, JavaScript, HTML, CSS), including - 13 years in WordPress programming including performance optimization & server administration and 12 years in Magento & Shopify. - Proven ability to deliver high-ranking, SEO-friendly websites without additional SEO efforts. - 6 years of experience in Python-based machine learning. - Fluent in English. - Strong knowledge in mathematics, physics, and quantum computing, continuously advancing knowledge in these fields. - Advanced expertise in complex systems (Machine Learning, Quantum Computing, Magento, WordPress), enabling precise decision-making, high efficiency, and consistently reliable results. Magento/Woocommerce/WordPress/Shopify: 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. 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 in this field. Page speed optimization & on-site SEO skill: I specialize in advanced PageSpeed optimization with over 14 years of hands-on experience improving real-world website performance across WordPress, Magento, and Shopify platforms. I optimize every layer of a site—from server configuration and database efficiency to clean, optimized code, caching systems, and lightweight front-end assets—to ensure exceptional speed and user experience. I resolve Core Web Vitals issues such as LCP, CLS, and INP/FID while preserving full design integrity and functionality. My focus is on sustainable, long-term performance improvements rather than temporary fixes, and after my work, PageSpeed scores can reach up to 100 on both mobile and desktop, helping websites load faster, rank better, and convert more visitors into customers. In addition, I implement strong on-site SEO practices, including proper HTML structure, schema markup, optimized headings, internal linking, metadata optimization, and search engine–friendly coding to enhance visibility and indexing. Python machine learning, deep learning and quantum computing: 6 years of experience in python machine learning and quantum computing. Web Scraping: 15+ years in advanced web programming, expert in Python web scraping, with experience in complex systems including machine learning and quantum computing. menos -

But when was the last time you used something that made you think, "This actually gets me"? That's the gap we're closing. We Build Products People Actually Want to Use. Not because they have to. Not because it's "good enough." But because it solves a real problem so elegantly that going back feels impossible. Web apps. Mobile apps. AI-powered automation. SaaS platforms. WordPress sites that convert. WooCommerce stores built to sell. SEO-optimized content that ranks. Banner and web designs that stop the scroll. Whatever you need — we build it to feel intuitive, perform flawlessly, and scale without falling apart. From pixel-perfect HTML/CSS interfaces and Node.js backends to cloud-computed data pipelines and WordPress/Elementor builds — our stack is as broad as your ambition. We handle everything from WordPress Design and SEO Writing to full-scale SaaS architecture and AI automation, all under one roof. Our Philosophy Simple beats complicated. Every time. We strip away the noise so your users focus on what matters. Your business drives the tech — not the other way around. Innovation should be invisible: the best technology doesn't announce itself, it just works faster, smarter, and more reliably than anything before it. What We Actually Do We partner with businesses to build new products from the ground up, modernise legacy systems, automate intelligently with AI, launch scalable SaaS platforms, optimize for search with data-driven SEO strategies, and connect everything — APIs, cloud services, third-party tools — seamlessly. We don't just write code. We ask the hard questions, challenge assumptions, and iterate until the solution feels obvious all along. Why We're Different The market is drowning in agencies churning out generic MVPs. What's rare? Teams who genuinely care about craft — balancing innovation with practicality, speed with reliability, and function with feeling. We're obsessed with building software and digital experiences that don't just check boxes — they earn loyalty. Who We're For If you want a quick fix or the cheapest option → We're not your team. If you want a product, a website, or a digital presence that starts strong and gets better over time — one your users, your team, and your investors are proud of — let's talk. menos -
