    3 stories: With my web design and SEO skills, I generated $50,000/month of additional income for local service-based clients in less than 6 months. How did I do it? Pinyerd Law already had good starting point, but they were missing just a little bit to get them over the edge. Their design was a bit rowdy. Their site speed was slow. Their maps were high, but they weren't in top 3. To get great results, I can't only be a good provider, I need to work with a good client as well. Meet my custom tailor-made approach in marketing and web design. Are you tired of cookie-cutter templates that make your website look the same as everyone else? The cheap price comes with cheap looks. Let's get your aesthetics unique and tailored for higher conversions and more leads and sales. Typical problems your business is experiencing: - Unprofessional website aeshtetics murdering your sales opportunities? - Your customers not being able to fill out the form on your site? - Ranking on the 2nd page of Google? - Slow and sluggish websites? - Unreliable freelancers? Work with an official Google partner agency. It's time to put those things in your rearview mirror and look forward to Done For You, profitable websites that convert on autopilot, printing money while you sleep. If you value aesthetics, AND you want to have a blazingly fast, technologically sound website, you're in the right place. Revenue-generating websites require speed, high Google rankings, and reputable aesthetics. Your competition is investing in its online presence, and you can't afford to lag behind. Others aren't investing in cheap templates built on Fiverr. Neither should you. Getting all of this together is hard, but it doesn't have to be. I've personally overseen and built over 3,500 websites throughout my 15-year career. Do you know how High the Cost of a Slow Website Speed is? Your website's slow performance is destroying your revenue and killing opportunities that could otherwise enhance your profit margins. Decreased customer satisfaction impacts your earnings but also harms your Google rankings, leading to a decline in traffic. This cascading effect means even more revenue lost for your business. In today’s digital world, sluggish performance doesn't just lose sales; it kills your bank account. The Frustration of Waiting Picture your customers waiting for pages to load, their growing frustration, and the opportunities lost as they turn to competitors. In the era of instant gratification, no one has the time to wait. Slow speeds, poor experiences, and declining Google rankings are eroding your credibility and undermining your marketing efforts. Let me help you Achieve High Performance My specialized website optimization transforms your site into a high-performance engine. Envision your website with lightning-fast load times, seamless navigation, and a user-centric design. I offer sophisticated SEO and a premium user experience, ensuring your site adheres to core web vitals and improves your Google rankings. Converting Clicks to Customers Beyond speed, I focus on conversion design and content. It's not just about a fast site; it's about creating a journey towards a conversion for your consumers. My work aims to leave a lasting impression, turning visitors into loyal customers. With strategic placement and compelling content, I guide your audience to make purchases, maximizing your return on investment. Every element, every word, is crafted to convert and compel, ensuring that your site isn't just visited but remembered and acted upon. Unlock Market Influence Reserved for the Big Dogs Expect more profits, happier clients, and a robust brand perception. Your clients will enjoy the speed and simplicity, making their buying decisions easier and boosting your sales. With my expertise and innovative solutions, I promise not just a faster site but a comprehensive digital transformation that elevates your brand and bolsters your bottom line. Your website will become a powerhouse of conversion and a testament to high performance, providing you with the competitive edge needed in today's market. Ready to take it to the next level? Hire me for the web design consultation. I will provide you with the opportunity to overview and help you grow.

    Over the last decade, I, Michael Noe, have navigated the vast and complex world of full stack development, crafting a career that spans a wide array of technologies and platforms. My journey began in 2010, armed with a keen interest in Angular, .Net, and Python. During these early years, I delved deep into these technologies, developing a robust foundation that would serve as the bedrock for my future endeavors. However, the ever-evolving landscape of technology beckoned, and in 2016, I pivoted towards a more focused specialization in React and Node.js. This shift wasn't merely a change in tools; it represented a deeper commitment to mastering the cutting-edge of frontend and backend development. React allowed me to create dynamic and responsive user interfaces, while Node.js enabled me to build scalable and efficient server-side applications. This combination proved powerful, allowing me to deliver comprehensive solutions that met and exceeded the demands of modern web development. Parallel to my journey through the intricacies of application development, I ventured into the realms of cloud computing with AWS and Azure. These platforms have been instrumental in my work, providing the backbone for deploying and managing the applications I've built. My familiarity with these cloud services has allowed me to design and implement scalable, resilient, and highly available systems that leverage the best of what cloud computing has to offer. Reflecting on my career, it's clear that my journey is one of continuous learning and adaptation. From the foundational days of Angular, .Net, and Python to the current era of React, Node.js, AWS, and Azure, I've embraced the challenges and opportunities each shift presented. As I look towards the future, I remain committed to exploring new technologies and methodologies, ready to leverage my decade of experience to innovate and drive success in the ever-changing landscape of full stack development.
