    Howdy folks! I'm a professional web developer with over 5 years of experience, specializing in fully-custom WordPress development. This includes building out custom themes from scratch, implementing bespoke functionality via custom plugins, and other back-end customizations and integrations. In my time as a developer I've worked on a wide range of wordpress sites, ranging from small mom-and-pop business landing pages all the way up to enterprise-grade systems. I'm especially well-versed in customizing and extending GravityForms, and have built out numerous custom plugins that help businesses integrate GravityForms with their existing business logic and systems. I also have extensive experience in getting WordPress sites to properly integrate on the back-end with other third-party business platforms, such as Salesforce. Other wordpress-oriented services I offer: - PHP upgrades. If your site is running on anything below PHP v8.1, your server is running code that has passed it's official end-of-life. Usually this isn't a *huge* deal, but over time it can create security vulnerabilities on your site, especially depending on what third-party plugins you are using. - Server migrations. If you're looking to move your site from one host to another, no problem! I can setup a seamless transition that migrates all the files and database, so no content is lost and there is no downtime. - Malware/hacked site recovery. This can be a bit of a wildcard depending on the specifics, if you're facing a problem here, let's chat! So if you have any custom wordpress needs, don't hesitate to reach out! I'm a native English speaker based out of Boston, and I'm always happy to hop on a video call to chat more.

    Although I work on projects which cross a multitude of platforms and disciplines, the core of my passion is solving problems in creative ways. My wide skillset includes skills in web development, data engineering, 3D design, dev/ops, and game development. Although it may seem like I am a jack of all trades, master of none, I believe that this is actually to my benefit. My primary characteristics of flexibility, strong work ethic, and willingness to constantly develop allows me to bridge the gap between different disciplines. Throughout my college studies in Computer Science, I absorbed a lot of expertise that is immediately applicable to creating virtual experiences. Learning about computer graphics, physics, UI design, and computer aided design all enhanced my ability to create user friendly and immersive software. I also learned game engines like Unity and Godot for my own games, in which I implemented features like navigation, threat assessment, and modular unit control. Of course, I have also learned useful 3D modeling skills in my free time in software such as Blender and SolidWorks.

    I am an IT Consultant and software engineer, specializing in blockchain and Linux Administration. I have worked on a range of projects, particularly pertaining to back-end development, cyber-security, arbitrage crypto trading, pen-testing, data analysis, API integration, web scraping open source intelligence gathering, and more. My primary programming languages are Python3 and the Bash shell. My IT career began in 2014 as an IT Consultant for the city of Fitchburg, Massachusetts. Originally I offered to volunteer my time to better the community, with the theory that if you are good at something, eventually someone will pay you to do it. As it turns out, I was correct, and it wasn't long before I was offered a job. My first task was installing Linux Ubuntu on several hundred computers that were donated to the city by the Federal Reserve Bank of Boston. Obviously the disks were wiped before we got the computers, so there was no operating system. I saw this as a perfect opportunity to help my community transition away from proprietary software, embracing open source systems instead. During 2016-2017, I co-founded a server hosting company. As a client of several different hosting providers myself, I felt that I could do better. This experience taught me much, including KVM and other virtualization technologies, sharpened my web design skills, and made me a better businessman. Late 2017 through early 2019 I worked on a confidential project relating to cryptographic currency trading and automation. This job changed my life forever; the experience was a catalyst to success and financial freedom. My role was diverse; I was both the project manager, one of the developers, and the architect for the system that we built. Today I am a self employed contractor, working as a software engineer, system administrator, and consultant. I specialize in security and blockchain, and I have written countless security tools and several automated trade platforms. More recently I have began to specialize in administering various blockchain/cryptocurrency technologies -- for example, recently I began working as an engineer/sysadmin deploying a block producing node on a proof of stake network. And most recently, I am doing a lot of web3 related projects. **Note for Prospective Clients**: If you're curious why after ten years of only ever getting 5 star reviews, I somehow managed to get a 1 star review, the answer is that I was deceived, manipulated, and extorted by that so-called "client". I lost six months of my life, and then had to pay for the privilege. That was not a job. It was a hit job.

    You can think of me as a General Contractor for the web. I build and run websites; browser apps (aka SaaS); native-like mobile web apps, which can be released in app stores; API integrations; information dashboards; automation controllers; and just about anything else you can dream of that runs on the web. Small to medium projects I can turn around in matters of weeks to a few months, and for larger projects or faster timelines, I can always subcontract parts of the work or help you find subs. Also happy to consult or fill a role in databases, back-end, front-end, API development or integration, design, security, testing, QA, etc. Unlike most modern developers, I use a clean, "boring" approach, avoiding the endless new frameworks etc., which results in less bugs and headaches with the code and a better end product on the web.
