    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.

    As a Junior Web Developer, I have over 4 years of progressive experience in the conceptualization and execution of comprehensive web sites branding and outreach initiatives for non-profits organizations and start-ups firms. Over the course of my career, I’ve worked closely with clients to optimize digital engagement and communications efforts which led to increases in audience reach. I create user-friendly fillable forms where a user can type text in, select options from drop-downs, check boxes, press buttons, etc. For more complicated conditional behavior, additional automation, and complex calculation, I use JotForm and Cognito Forms for clients with the need for easy maintenance. Being Bilingual, I had the chance to develop bilingual websites in WordPress & Squarespace as part of engaging with a more broad audience. I'm a fast learner who enjoys a challenge. My communication skills and ability to hit deadlines are 10/10. I like to say "I'm not finished until you're happy". And I mean it. My website is MarcosZapata.com and it features what I am capable of designing. I look forward to working with you soon!

    Welcome, community. Let's get down to business? Let's see the numbers: 🔹5+ years of experience as a Front-End/Fullstack M(P)ERN engineer. 🔹Next.js for more than 5 years of experience and I really enjoy working with this framework because of SSR, SEO, and other features that are not built-in in React.js. 🔹Material UI, Ant Design, TailwindCSS. For rapid development quite often we need to use these UI libs besides clean HTML/CSS. 🔹PostgreSQL / Firebase / MySQL / MongoDB / AWS S3 🔹HTML5 / CSS3 / ES6. 🔹Expert knowledge in GitHub/GitLab/Bitbucket. 🔹Figma / FigJam / Adobe XD / Zeplin / Invision - familiar with all the design managers. 🔹Slack / Jira / Click UP / Trello - familiar with all these work messengers and tasks managers. Past experience: ✅ 5+ Years of commercial experience in web development projects. ✅ More than 12 commercial projects all of which went into production. ✅ Successfully delivered multiple projects, demonstrating expertise in both front-end and back-end development. ✅ Strong knowledge and deep experience with everything related to JavaScript. ✅ Expert in TypeScript. I consider it's absolutely must-have technology to be used both on the fronted and backend. ⚛︎ A thorough understanding of the React.js library and its core principles. ⚛︎ Used Redux library in all previous projects. Thanks to it familiar with Redux-Thunk/Redux-Saga/Redux-Toolkit/Redux-Observable. Additional technical background: ✔️RESTAPi's integration/ RESTFULLAPI's integration (fetch)/ Websocket API's integration(socket.io)/ jQuerry ✔️GraphQl API's technology (Apollo,Relay) - to my mind very convenient technology and fast. ✔️Built efficient server-side applications utilizing technologies such as Node.js and Nestjs. ✔️Troubleshot and debugged complex issues, employing strong problem-solving and analytical skills. Talking about myself I'm a freelancer with conversational English and I have previous experience working in English spoken teams. I can handle daily calls and meetings with a team if they are within my working hours. By hiring me for a project, you get a reliable partner who is ready to provide a free rough estimate of how long it will take to translate your design into high-quality code. I prefer to work with the latest ES6 standards and work with functional components, not with class-based components. A functional component is commonly better because there is no need to create an instance of the class in JS/TS, so React will simply call the function and that's it (in terms of performance). Besides that, there is also Error Boundaries functionality which is not available for functional components yet (in terms of capabilities). All other stuff is pretty much reproducible by each other and the choice depends on the preferences of the developer or project requirements and/or code guidelines.
