    The underlying cause of software project failure is communication. Does not matter if it is a lack of communication, or miscommunication, or just clarity of what was communicated, the problem is the same. This industry is littered with schemes and gimmicks that supposedly make building software easier and bulletproof and yet an alarming number of software projects fail. Why is that? Communication. Because I understand this, it is my strongest focus when building software, and it is why I am so successful at it. I will talk to you about what you want, help you understand what you really need, work through exactly how it will be delivered, when, and at what cost. I would be happy to talk to anyone contemplating having software built to give my thoughts, I have plenty to share. But I have to warn you if you talk to me you will want to work with me.

    I've been working with technology since 1992 in both software development and network infrastructure positions. I started as a developer and have focused on building custom financial, inventory, and workflow software for employers and customers. I have also worked in technology infrastructure positions such as network and IT management. I built my first web server in 1995 and almost immediately built my first web program using a C language CGI program. Since then I have used almost every server-side web development platform: Perl and Python CGI, fast CGI, Zope, Django and Flask with Python, ASP.Net, Node.js, and most recently Deno. Client-side, I've used Javascript (since before it was popular), spent many years using JQuery, then Knockout.js. I have used many of the popular front-end environments today, primarily Angular and Vue.js. In addition to web-based work, I have developed a number of service applications for customers, normally Windows-based services in .Net. This has allowed me to leverage my knowledge of different databases and network environments to build custom-tailored solutions to fit many diverse needs. I have also done numerous large-scale document and data conversion projects for many document imaging systems. These involve careful planning, understanding and mapping data between systems, document format conversions, and meticulous record-keeping.

    12+ years of experience with developing websites or various aspects thereof: PHP, MySQL, JavaScript, jQuery, HTML, CSS, and more (WordPress Themes and Plugins included). Can build your site with provided website designs or simply point to almost anything you see on any website you like, and I can reproduce it. From initial site creation/development to continual maintenance or upkeep (including WordPress security monitoring and updates), got you covered. Need website hosting? No problem! I am a re-seller of a premier, top-quality hosting company with an outstanding track record, and I provide NO CONTRACT web hosting for my clients, so the FREEDOM of choice will always be yours. I provide relatively low-cost, all-in-one solutions if you would like me to keep an eye on various security aspects of your site(s) and keep your site(s) updated. Site migrations, HTML-to-WordPress, site add-ons, plugins, or themes... whatever your needs, I'll do what I can to reasonably assist - with honesty, fairness, integrity, thoughtfulness, and forth-rightness. (And, I expect the same in return please.) Need a custom page-builder for your WordPress website? With your copy of Advanced Custom Fields (ACF) Pro, I can build you a custom page-builder that will make your life a lot easier, allowing you to develop and make the changes with relative ease and no need for any special HTML coding. I make the elements you specify, and you chose where to place them on your website. These days, I find myself working primarily on WordPress sites, as my life is about freedom, and WordPress allows greater freedom for myself and my clients. Also, it can reduce development costs substantially, which I think is a 'good thing', as I treat others how I wish to be treated. No need for design... feel free to bring your design files or provide examples of what you wish to build, and I can reproduce for you. For those who are reasonable, I will always be there to help. For the crazies or selfish, and it seems there are more and more all the time, I'm not your guy (and all the best to you in your endeavors)! I only work with the reasonable and those who are mutually respectful. The first sign of 'coo coo', and I am out the door. This is mainly why I don't work for a big company. I pick and choose my clients/relationships, just as much as they choose me. It's an equitable trade of mutual respect and reciprocity. Without these aspects, there is no healthiness in the relationship, and I choose healthiness all day long... it's something you should know about me from the beginning, as I do healthy and not crazy or selfish/greedy. Background working with Linux (command line only is perfectly fine), web servers, firewalls, email servers, file servers, SSH, and many other facets of running 'IT' systems/servers. Need an AWS EC2 system admin... gotcha covered. "Geek"? Yes, kinda... I also offer full hosting as well, and my goal is to develop strong, lasting relationships, and will never leave a good and reasonable person handing or alone after any initial project is completed, as a website is never truly "done". My development environment/processes: 1. Linux/localhost 2. vim - gulp with sass, minify, etc. 3. git version control - dev, staging, and production* Training: I enjoy sharing my knowledge with those who are sincere in their desire to learn if it's WordPress, HTML, CSS, or more. It's always a pleasure for me when a client has an "Ah-ha" moment. It's a fun and rewarding experience for me. :) Often times, I make videos/screencasts for clients for future reference, which can help tremendously, as there can be a lot to learn at times w/ custom sites where the client wants control and freedom. Please, if you ever have any questions, ALWAYS feel free to ask. My door is always open for good folks. verilucis.com Thanks for taking the time to read my profile, and hope to hear from you. Perhaps we will have the opportunity to work together! Hope all is well!! *Staging environment not always required
