    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.

    I have over two decades of experience designing, implementing, and maintaining applications that meet large, complex customer needs. I have taken many critical applications from pure vaporware to working. Much of my code runs in production for large financial institutions serving their most complex corporate clients. I am always interested in positions that provide a significant new challenge over what I have done in the past. Recent projects include: • I reviewed/audited a large Java codebase that had come to the client through merger and acquisition to confirm that the code was complete and had, in fact, all been delivered to them from the seller. • Designed and implemented REST APIs and other backend components deployed in Amazon AWS. These APIs process large volumes of payments for business and individual customers. Technologies used in this job include: • Java • Spring Boot • MySQL • ActiveMQ • Docker • Amazon AWS (ECS, EC2, RDS) • Linux
