I'm a motivated young man. I'm new to adulthood, but I'm not new to coding. I have been coding for over a decade now! "WHY SHOULD I HIRE YOU OVER OTHER DEVELOPERS?" 1. I have great communication skills. Miscommunication is very rare for me. 2. I work long hours. I wake up at 4AM Mon-Fri, so your projects will get done quickly. 3. Some web developers I know are very specific in what they do. They're excellent at JavaScript, for example, but they can't code CSS or PHP at all. I'm not like them. I have broad experience from Composer to Web Host management to Calculus to Cyber Security -- things that often go overlooked. 4. I use AI assistance in everything I do which reduces the number of mistakes I make. "HOW DO YOU COMMUNICATE?" I send detailed messages round the clock and my clients gets back whenever they can. Any texting or email platform will work. However, this kind of communication only works when both parties send highly detailed messages. If the project requires more back-and-forth than that, I like to schedule for a phone call.

Hello! I’m a US-based individual consultant and all work is performed by me personally. I do not outsource and I do not subcontract without your express permission, EVER. I have verifiable references from long term clients. I am an experienced Subject Matter Expert API Implementation Engineer using PHP Javascript Python SQL HTML and CSS to build web-based apps and add functionality to websites. I have extensive experience with OpenAPI/Swagger/YAML and API documentation. POSTMAN. REST GraphQL and SOAP APIs. I’ve worked with dozens of the major APIs from Amazon, Meta, Google, Stripe and Authorize.Net, MailChimp and Constant Contact, ActiveCampaign, Dialpad, you name it I can figure it out!

I also have extensive MVC experience across all major frameworks, including Laravel, CodeIgniter, and Yii. If you need it, I can build it! I’d finished a long term project for Deloitte Touche Tohmatsu US and was mostly inactive on the Upwork platform for over a year. Before that, I was Top Rated Plus for many years. When I got back on Upwork this Fall, I accepted a project and everything was going wonderfully. I truly to this day feel that I gave this client the excellent service and care I give to all my clients. I truly don't understand the awful feedback he left, because I was diligently building the system he hired me to build, even working 7 days a week to get it done fast. Since then, my JSS was tanked, and getting work on here has been 10 times harder. Please restore my faith in humanity and look beyond the current JSS to my many, many 5 star feedbacks and hire me to help me get my JSS back up to 100%! I will truly go to the ends of the Earth to make sure you are happy with your decision to hire me.

I am a full stack web developer with 9 years experience designing, developing, and testing web applications in the cloud. I have been a contractor for the past 8 years and have worked on multiple projects ranging from website audits to database administration. I have worked with multiple APIs and SDKs that range from forecast APIs to ecommerce APIs. Since starting on UpWorks, I have worked on multiple successful projects with little to no issues learning the software and building the features or applications that the clients are looking for. Before being a contractor, I worked as the sole developer at a start-up (Delta Five Systems). Delta Five is a robotics company that works with the hospitality industry. Their main product is a bed bug trap, which will automatically lure, capture, and report a bed bug incident within the room. At Delta Five I created the website, dashboard, device interface (Which had thousands of devices connecting daily), and the API. Since becoming a contractor, I have worked on multiple successful projects. I worked on Network Insights, an email analysis tool that analyzes communication between employees and clients to determine where communication is lacking. This tool uses multiple messaging APIs (Slack, Office 365, and Gmail) to allow companies to run reports to determine the point in which employees and clients are allowing the communication to slow or stop. Another early project was eHangar, an interactive airplane panel designer that allows users to create and manage airplane panels by dragging and dropping instruments on the web page. While creating the design, it automatically updates the price and weight based on the manufacturing specifications. I have also worked with True Blue Life Insurance and helped them with their life insurance quoting system and WordPress site. When working on the WordPress site, I mainly worked on plugins and the SEO . My favorite contract to date is with BuyItLive, a company that harnesses the power of social media in order to give small businesses a step up by helping to increase their conversion rates and allowing users to manage their orders and sales in one location. By connecting to Shopify, clients have the ability to easily import from their current shop. Knowing that all users are not the same, we built multiple payment options using payment APIs (Stripe, Square, WePay, Sezzle, and PayPal). I am always interested in new and exciting projects, and always will to work with you on price. My main goal is to build your application to meet and/or exceed your expectations!
