    As a Senior Developer with over a decade of experience, I’ve dedicated my career to mastering backend development and resolving complex performance issues across the entire stack. My expertise spans coding, databases, and underlying operating systems, where I’ve consistently delivered high-performance, scalable solutions. I specialize in optimizing and troubleshooting with a deep proficiency in Rust, PHP, MySQL, Varnish, nginx, Linux, FreeBSD, and AWS. My work has empowered clients like AWS Professional Services and Shure Inc. to achieve their goals, from building APIs that handle over 100,000 requests per second to creating custom, geographically distributed high-availability CDNs. One of my proudest achievements is maintaining an eight-figure monthly billing system, ensuring both reliability and efficiency at scale. Beyond technical skills, I’m known for my ability to communicate complex ideas clearly to non-technical stakeholders while effectively leading and mentoring junior developers. I’m passionate about continuing to push the boundaries of what’s possible in backend development and am always eager to take on new challenges that require innovative solutions and high-level problem-solving.

    Hi, my name is Andrew and I began using Wordpress when it first began. I've spent most of my waking hours for the last ten years designing, programming and operating Wordpress sites. One of my specialties is taking an idea from scratch and creating a full-fledged platform. I go beyond to produce sites with a unique, outstanding, contemporary look-and-feel. With extensive knowledge of web mechanics, I'm able to optimize complex integrations to require little-to-no maintenance while running on their own for years. I am a PHP programmer at heart and create features that are best suited for the job at hand, as opposed to trying to fit a job into features that I can find in pre-existing themes and plugins. I'm also attuned to performance issues and do a lot of repurposing of plugins. I also specialize in new and creative e-commerce solutions and bringing customized login panels for administrators to handle the website, while bypassing the clunky admin panel used by most wordpress sites. I can redo sites for design and optimization and can fix anything. I'm a geek at heart but pride myself with EXCELLENT customer service.

    I'm an Oxygen Builder specialist - I had a senior support role on the Oxygen Builder support team for three years and I know the builder inside and out. I usually build based on a Figma design - it's the quickest way to build a site as it's so easy for me to see the pixel-perfect design, rather than guessing based on a PDF or something similar. I have also spent that time working with ACF, and I have built multiple sites where the content is fully editable using ACF so that users don't need to go into Oxygen. For animation, I use Motion.Page or CSS Keyframes if the animation is less complex. I appreciate that my rate may be higher than what you would be looking to pay, but I can assure you that I will be noticeably faster and more thorough than similar people applying for this gig.

    I have over 25 years of experience writing software and administering databases. I am a PHP web developer with experience in Laravel, CodeIgniter, CakePHP, core PHP, and some Vue.js. I prefer to use an MVC pattern as provided by a good framework such as Laravel or CakePHP, but can also work with older PHP applications. I design and maintain databases in MySQL, PostgreSQL, and SQL Lite. I started as a PHP developer using the CakePHP 2 framework; this is where I first learned the MVC pattern, where manipulating, presenting, and controlling data is abstracted out. I then added SASS, to make CSS easier to write and maintain. For the user interface, I use bootstrap or the tailwind responsive framework along with jQuery or Vue. For non-Vue applications, I can use Smarty for view templates, but am also well-versed in using Blade, CakePHP, and CodeIgniter templates. I prefer to use Laravel for most projects; it provides better overall functionality than other frameworks and a superb ORM. I have recently started using Vue in projects via an open-source project called Inertia.js. Inertia bridges the gap between Vue and Laravel. This gives the best of both worlds where you get the power of Laravel on the back-end and the modern, sleek feeling of Vue on the front-end where your customers interact with the system. I started life after college (1998) as a Microsoft Visual C++ developer with some Visual Basic. In that role, I developed applications for law enforcement, 911 centers, jails, retail businesses, nursing homes, and trucking companies. I then moved into the .NET Framework in 2001. I set out to learn C# and have since developed many object-oriented and tiered client/server applications. These include applications for GIS mapping systems and some data mining and sharing initiatives. I have created custom TCP/UDP servers and clients for low-bandwidth mobile applications. I have worked with O/R mappers such as LLBLGen Pro and became accustomed to using entities in data layers rather than reading/writing data directly. My first database was Access 95 (yes, I know). From there, I moved into SQL Server 7.0, where I designed and maintained many databases. Database concepts such as normalization/denormalization, primary/foreign keys, and check/default constraints are not new to me. Whether it be T-SQL, PL/SQL, or MySQL, I am proficient with database programmability, such as triggers, procedures, functions, and views. File organization and usage, backup and maintenance, and database efficiency are also strengths. I currently primarily use MySQL, where available and PostgreSQL where it is not. Other databases include SQLite and Oracle. I have used a number of servers for hosting my web applications. I prefer either Ubuntu or CentOS running nginx and php-fpm with MySQL for the database. With the right configuration, this simply offers the best performance. I am proficient in the use of source control systems such as Git, Mercurial, SVN, Vault, and SourceSafe. Git really is the best choice here but Mercurial comes in at a close second. During the past two decades, I have created and maintained custom line-of-business applications, with a focus during the past ten years on web applications. I feel that I can be an added asset to your organization, even if it is only for the short-term. I've done a mix of short projects, several-month projects, and long-term engagements lasting a year or more.
