Are you looking for a "vanilla" application that is lightning-fast, perfectly responsive, and built on deep architectural knowledge rather than bloated libraries? I build web solutions that perform because I understand the engine under the hood. Why Choose My Expertise? ===================== Browser Extension Specialist: I have developed over 80 browser extensions in the last 6 years. I specialize in the modern WebExtensions API but have the deep-rooted experience of building cross-browser codebases for IE, Firefox, Chrome, Opera, and Safari. The "Zen" of Performance: With over 20 years of programming experience, I don’t just write code; I craft it. I’ve reached a level of mastery where I prioritize efficiency, security, and maintainability over "fast and messy" fixes. Business-First Automation: Entrust me with your business processes, and I will automate them into a seamless workflow. While I operate under your vision, I provide the proactive guidance you’re paying for—identifying pitfalls before they happen and optimizing your logic. Technical Philosophy ================ I am a perfectionist who views code as an art form. If you need someone who is self-managed, hyper-focused, and capable of translating complex requirements into elegant, high-performance reality, we should talk. I’m not just another developer; I’m the one who fixes what the others couldn’t. Projects best respond my experience ============================ ▸ Browser extension (single codebase Chrome+Firefox+MsEdge) ▸ Reverse engineering of web apps ▸ Custom outreach tools for LinkedIn, Instagram, X or any other platform ▸ Reactive UI ▸ NodeJS Rest API server / website ▸ Maps, Social media API apps ▸ Parallax animation (reversible) ▸ CSS animations for UI ▸ Crossite widget, or any other advanced things Next part is about my stack, it's boring to read if you're not a developer by yourself. ================================================================== I’m a vanilla JavaScript (ES6) writer. I can use libraries, but prefer to write vanilla. I make perfect non lagging animations, parallax pages, widgets. I’m pretty good at design and usability. I’ve done a lot of things with HTML5, CSS3 and relative technologies (Sass, Stylus, Haml). Using node.js in my daily life (Feathers, Express, nedb, passport, jade, gulp etc). Used backbone and knockout, mixed with knockback far before react. JQuery, prototype, underscore... Had experience with Sencha GXT(GWT) using JS and Java API's both. Had strange experience with flash. Had to deal with Google and Yandex maps API, some APIS of Facebook, Twitter, Instagram, VK, and moar. Build few REST API servers for my extensions. Used version control systems. Git(flow), mercurial, subversion. Touched CVS и Bazaar. I’ve made some desktop apps using WebView. I’ve had some experience with C/C++, Java, Python, Go, and (Fie!) PHP; nedb, mongodb, redis, MySQL. Love shell, have configured nginx, apache, php, mysql, samba. Used Jira, Mantis, Bugzilla, Trello, Basecamp, Redmine. Asana is my favorite.
