    **NOTICE:** I AM NO LONGER ACCEPTING ANY PROPOSALS. After more than a decade on Upwork, I'm leaving. It's terrible and abusive to freelancers and you should leave too. Upwork lies to their freelancers, changes ToS mid-contract, do not protect their freelancers from abusive businesses, and ignores the community's support needs. They're greedy, greedy, greedy, and have taken to trying to squeeze freelancers for everything they can instead of improving their platform or making the market safer. They ignore the abuses of scammers while milking their freelancers. It's not a coincidence that scammers flock to this platform and Upwork has no interest in doing anything about it because it makes the platform look more active than it really is. I suggest you get out! ----------------- Hey, My name is Jason! I'm a spirited PHP programmer and software engineer with a broad spectrum of talents. I've spent half of my life coding in some capacity or another, but most of my focus and energy in the last 12 years has been on web development for the Wordpress framework, both front-end and back-end. The non-nerd TL;DR ---- If you're a small business looking for an experienced developer with a proven track record for the Wordpress platform, then you've probably come to the right place. I've built up and torn down enough Wordpress sites at this point that I would safely use the "e" word - expert. I know the pitfalls, 'gotchas', and nuanced behaviors in Wordpress that only comes from long and committed experience with the platform. Whether it's site migration, custom plugin creation, or theme development, I can get you where you need to go. The Juicy Parts ---- Most of my work has been development for Wordpress. I'm an experienced developer for plugins and themes on the Wordpress platform and a competent back-end developer and server administrator. I build highly-available, resilient and secure distributed website applications. Preferred Work - **Implementing New Website Features** - I love system design! I love planning the data structure, building out system requirements, and implementing the final solution! - **Front-end Design and Creative** - I love UX/UI design and am a competent Figma user. I can design, slice and implement my own designs, or one that you provide. - **Large Projects** - I prefer longer contracts with lots of different kinds of tasks. Tiny contracts or monotonous work don't really appeal to. - **Maintenance/On-call Retainers** - My services are available on retainer. This means that I can handle your site's issues as they crop up, without having to find a developer every time. Most experienced with - Server Administration (*NIX, VPS, Docker) - PHP (Wordpress framework) - Javascript/Typescript (Frontend/React and Gutenberg Blocks development) - CSS3/SCSS (Frontend styling and design) I am an experienced administrator of LAMP stacks (Primarily Ubuntu server management.) I've developed dozens of custom plugins and themes for clients on the Wordpress platform. I've also done a number of "emergency interventions" for compromised websites. (Hardening the platform, using Apache to strengthen sensitive areas, using CLI tools like grep to search for and eliminate compromising scripts, etc.) Experienced user in: - Github/Git - A number of IDE's (I prefer VSC and GNU Emacs) - Unix CLI (I use WSL for my development) I have experience with the following technologies and have done or worked on projects with them, though they haven't been my primary focus. - socket.io - Mozilla Audio Webkit - Java - Python (Primary experience with matplotlib, pandas, numpy and datasets) - C/C++ - Unreal Game Engine (C++ and Blueprints) Other ---- As a well-rounded geek, it's inevitable that I end up with my fingers in multiple cookie jars over the years. I have passion for and have done personal projects over the years in other fields such as: - Video production - Game development - Visual Effects and AV post-processing - 3D Animation and modeling - Audio Engineering and sound design - Music Production (Production and Mastering) - Data Analysis (Python) - Photo Manipulation and Editing - Icon and graphics creation Misc Talents - Fluent Spanish speaker (Viví en Chile por dos años y aprendí el Éspañol mientras que estuve allí.) - I'm a musician as a hobby and write music in my freetime. - I can probably kick your butt in a round of Mario Smash Brothers Melee My earliest programming memory is of my father teaching me procedural programming logic with Q-Basic on an old MS-DOS machine at about age 10. When I was 16, I built and maintained my first site. I also have countless years of online SEO/Marketing experience through everything from Google Adwords, Direct Online Marketing, Backlinking, and modern Ad Campaigns through social media. Go ahead and shoot me an invitation. I'll take a look at it.

    I write code that smells like Lilac and reads like Byron. I have a compulsive love for elegant architecture, Stockholm syndrome for clear documentation, and a solid background in clean code. I’ve taken multiple projects from ideation to production, discovered new mathematical transforms, led teams of developers, wrangeled interns, and presented to executives. I’ve tested my mettle contending with stormy seas in small watercraft, particularly puckering precipices on skis, and freezing desert nights without so much as a tent to shelter under. I’ve gone ice breaking in a canoe, sent the fingers on ski blades, been skinny dipping in frigid alpine lakes, driven in LA, and have stories enough to last long into the night. All this to say, your biggest, grimiest, oldest ball of mud doesn’t scare me in the slightest. When things go awry in the worst of ways, I get loud and I lead. I combine the knowledge of a software engineer with the swarthy gumption of an adventurer, and the hard won experience of both. Let me build you something beautiful!

    I am a software developer and consultant with 25+ years of broad experience. I am currently focused on web applications and iPhone/Android mobile apps and games. My clients are small to medium organizations as well as design agencies and freelancers needing help with their client projects. I am a principal at Supercosm LLC in Seattle and a member of the digital arm of Local No. 12, an experimental game design collective. I take a thoughtful approach to all projects. I am adept as balancing the competing needs of budget, time, and scope, and my focus is always on solving the problem at hand rather than any specific technology. I desire long term relationships and many of my clients are repeat customers that have been with me for many years. Web Development I work with clients as well as other designers and developers in roles from architecting and building entire web applications to solving specific technical problems on short notice. CakePHP and Laravel are my current platforms of choice, but I also have experience building web apps in Java+Spring and, more recently, Node.js + Elasticsearch, and Magento, among others. I can work on very specific parts of a project, build an entire site or app from design documents, or help you take an idea all the way from discovery to launch. Mobile and Game Development I have 10+ years experience developing native iOS apps and games and have also done some Android work. As part of Local No. 12, I led development of Dear Reader, an award-winning launch title on Apple Arcade in September 2019. I have also developed, launched and continue to maintain numerous iOS/iPadOS/tvOS apps for clients.
