I have 21 years of general linux experience with apache, php, bash, python and various other scripting/programming languages. I have 7 years of expert level experience using memcache/redis and nginx application accelerator proxies based on Redhat and Ubuntu with php-fpm, apache, nodejs, java, .net and other application servers. These include zend, wordpress, drupal and several other web software suites In one of my previous projects I was been able to allow for up to 40,000 simultaneous user sessions across twenty apache application servers utilizing nginx reverse proxies, behind several F5 load balancers. Initial hardware was able to accommodate up to 4,000 users. Since the application was not stateless nor was it designed for data segregation between private/public data the nginx rulesets were very complex requiring rewrites, header injections/strips and even body regex find/replaces. I also have expert level experience with large scale wordpress clusters from the file service and db aspects. I have experience with appdynamics, nagios and large scale ELK logging. I have experience with AWS, especially linux EC2 containers, elastic beanstalk and cloudformation. I am highly skilled in troubleshooting complex multi-tier interaction issues using system logs, stack traces and wireshark packet traces.

**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 have extensive experience in building Simulations, Algorithms, predictive Machine Learning models and whole software ecosystems with multiple algorithms working together. My expertise includes classic Algorithms, Statistics and Machine Learning, Simulation, Backed development, Mathematical Optimization, Data Science and Cloud Engineering. I also have a lot of expertise in creating solvers for combinatorial optimisation problems using local-search based meta-heuristics in the Optaplanner framework (now called Timefold). I have extensive experience with deploying this kind of software and the whole development cycle, including maintenance. I also do the setup and deployment of these applications on cloud infrastructure. I can complete the whole project pipeline or only do a specific part of the project. Up to you! My previous experience includes writing Algorithms for large companies dealing with dredging, pharmaceutics, manufacturing, delivery, workforce organisation, waste management, banking, financial trading and others. I created algorithms for these companies solving problems related to scheduling, routing, task-sequencing, route-optimisation, predictive modelling, quantitative analysis, automatic Algorithm configuration and Simulation. Some of these algorithms were implemented using Optaplanner, some were completely custom, some where done using machine learning and statistics (using Python and Python frameworks), some with Simulation, but most were a combination of some of these.
