Renoir Boulanger

Wanna see this on my site and how I'm leveraging native custom elements? [Visit and *view-source* at **renoirb.com/notes/2023-06-29-hello-mentee**](https://renoirb.com/notes/2023-06-29-hello-mentee.html) --- Hello there! I'm Renoir, a self-taught software developer who’s been working in this field since 2002. Back then, it was known as the "Browser Wars," and I consider myself a survivor, a *veteran* from that era. Our main challenge at the time was ensuring that websites looked the same on every browser. While the basics remain unchanged, it has become much easier today, believe me! Throughout my career, I have held various roles such as founder, sole proprietorship business owner, self-employed contractor, and consultant. I have had the opportunity to work with notable organizations including the [W3C/MIT](https://www.w3.org/staff/alumni/#renoir-boulanger "For the World Wide Web Consortium attached to the Massachusetts Institute of Technology"), Mozilla on <em title="Mozilla Developer Network">MDN</em> for Compatibility Tables, <em title="Civil Aviation E.">CAE</em> (an aero simulation software manufacturer) for secure air-gapped deployment complexity, Walmart for deployment consistency, Exxon Mobil, and Ericsson Canada. Additionally, between 2002 and 2008, as well as from 2010 to 2013, I enabled design agencies to offer web services. From 2002 to 2009, I hand-built over 150 websites. During this time, I became a fan of 'Object Oriented CSS' and the concept of making CSS reusable due to repeating the same patterns frequently. Since 2009, when I started designing pattern libraries, I have constantly contemplated the idea of cascading in CSS, where base styling is combined with themes. This approach eventually came to be known as "Style Guide," "Design Systems," or "UI Libraries." Over the years, I have worked with various frameworks and libraries such as MooTools, YUI, Backbone, Angular, Vue, React, [Lit.dev](https://lit.dev/), and [FAST](https://www.fast.design/ "FAST is a collection of technologies built on Web Components and modern Web Standards"). Among them, Vue is my personal favorite due to its simplicity and native Web Components API. In recent years, I have extensively explored programmatic frontend generation techniques, including Vue's render tree, Backend For Frontends (BFF), Web Components, and even "Microfrontends." My focus has been on finding innovative approaches to enable web applications to support multiple languages effectively. Additionally, I have dedicated time to understanding and implementing proper accessibility practices, as well as adopting techniques that ensure long-term maintainability. Even before the term "full stack" was coined, I have always considered myself as one. Apart from web development, I also maintain a few Open-Source packages and have made contributions to projects like Nuxt.js, MediaWiki, [Mozilla Firefox Accounts](https://www.youtube.com/watch?v=KKeh9C4SMnw "See experimentations on self-hosted Firefox Accounts deployment that's now defunct"), and [WebPlatform.org](https://github.com/webplatform). When I mention "Constantly Thinking about the Web," it’s just that I have this fascination about it and literally can’t stop thinking about it, how it works, and ideas of how to do things with it. My interest ranges from efficiently tracing Linux kernel services using technologies like MariaDB, Redis, Memcached, PHP, HHVM, Python, and ElasticSearch, to analyzing HTTP traffic, sometimes employing instrumentation techniques like MiTM, Proxy logger, and Varnish. I also delve into how web browsers handle XML/HTML/XSL in their "Object Model" (known as DOM) and how events are handled, as well as the intricate process of CSS painting and how to annotate HTML to add meaning, like [Linked Data](https://www.w3.org/wiki/LinkedData). In terms of my personality, I must admit I am a bit quirky. I’m not the typical person, I’m rather energetic and imaginative. Even more so when it involves my passion. Be prepared for an exciting ride! If you're interested, you can find my resume in JSONResume format on my website. It is available in different forms, including HTML, PDF, and Word, all derived from the same source.

Kirill Erokhin

I teach Operating Systems and functional programming fundamentals to CS students and guide fellow professionals through legacy codebase maintenance, practical software architecture, and new language/framework learning skills. For students, I offer two types of sessions - one is a lecture-style session where I can go over course notes/slides on a particular topics and offer additional explanations and examples to improve your understanding of the material. Another type is an assignment take-up session where I can go over a past assignment and guide you through steps to solving it. For working professionals, I offer the following options: * Focused problem-solving sessions - if you have a particular issue that you're stuck with in a project you're working on, I can pair with you over Zoom screen-sharing * Code review - if you cannot understand how to work with part of your codebase or if you'd like a second opinion on work that you've just completed, I can pair with you over Zoom and do a live code review and/or prepare ahead of time and go over my findings on a call * Long-term mentorship - if you would like to learn some more fundamental skills or pick up a framework/design pattern/best practices, I can develop a custom-tailored learning plan that fits your skill level and schedule and offer regular teaching sessions with optional take-home exercises A bit about me --- I am a tech founder and a senior polyglot/full-stack developer, with a passion for teaching and mentorship. In a bit of spare time from my work, I am looking to help fellow software developers get more comfortable with our craft and exercise my teaching skills while I'm at it. So far, I've done a wide range of work - web app front-end and back-end, data pipelines at scale, DevOps/infrastructure, mobile (quite a bit of iOS and previously some Android) and some security. I have a reasonable taste for UI design and user experience, despite that not being my primary specialization. The industries I've worked in so far were heavily concentrated around finance/banking/FinTech and GovTech, although I've also been a founding developer at a couple of B2C startups and learned a lot throughout that experience. My personal research interests include operating systems and programming language theory. As cliche as it sounds, I try to learn something new all the time and I consider this of vital importance to my professional skillset. I always prioritize systems understanding and learning how to learn over memorizing APIs - and it's a philosophy that I try to share with my students as well. Teamwork and constant exchange of expertise with my peers is a close second most important value to me. A software product can be almost meaningless without a team that welcomes learning from failures, encourages curiosity and fosters true human friendships, and empathy both towards each other and towards the customers of the software we create. New client intake process --- 1. Intro/triage call [free of charge] [15 min] - this is a Zoom video call where I try to understand your background, the problem you're looking to solve and whether I believe we'd be a good fit for a productive mentor/mentee relationship. 2. Supplemental terms acceptance - as an independent contractor and not an employee of Arc, I ask my clients to accept a few additional terms that make session time measurement, scheduling and work product acceptance more precise, and further clarify the extent of our mentorship relationship. 3. Creation of Freelance Job/Scheduled Session on Codementor - if you haven't done that yet, I will ask you to create and assign me a freelance job and/or a scheduled session with a precise description of the topics we would be covering. For certain sessions, preliminary preparation may be required - if that is the case, we would discuss the details and estimated time ahead of time and a Freelance Job would be required to cover the effort of the preparation. Availability --- Please take a look at my Codementor calendar to plan intro calls and sessions. Generally, I am available between 3:30pm and 8pm Eastern Time (New York/Toronto), Monday to Saturday, but I try to schedule all of my teaching engagements between 6pm and 8pm whenever possible. *IMPORTANT: Urgent sessions are unfortunately not available at this time.* I am currently working through Codementor as a mentor, and unable to work as an on-call freelance developer. Please also note that I cannot provide consultations over chat - in my experience, it's generally more time-consuming for everyone, and copy-pasting code over chat can get messy. For those reasons, I only work through Zoom video calls with screen sharing. If you have any questions about the process or would like to book a call, I am happy to chat on Codementor - I should be usually available Monday-Saturday, 1pm - 8pm Eastern Time, subject to my other engagements. While I try to respond as soon as I can, I may take up to one business day or longer depending on how busy my schedule might get.

Aleksander Korzyński

I'm happy to help you with **C**, **Bash**, **GNU make**, **Git**, **Linux** and related open-source technologies. I've enjoyed doing this stuff since the 1990s and it's got ingrained into my memory to such an extent that I seem to remember arcane stuff (like C pointers to pointers😉) even when somebody wakes me up in the middle of the night 😎 I also have a passion for helping others to grow as software engineers. I was told I ask good questions. If you ask me for advice I won't do your homework for you, but instead ask you questions that will help you come up with your own ways to improve your code or infrastructure. 🎓 I'm also a co-author of an upcoming book on Linux: *Get Started on Linux by End of Tonight – Without Breaking Your Box*.
