    I'm a Python/Django developer with Linux administration experience, some DevOps skills and good knowledge of AWS Cloud. I prefer to work with the server-side but also have experience in developing for the front-end using Vue, jQuery, or vanilla JS. But the front-end is not my strong side. Along with coding, I can also help to setup environments and deploy the project. But I don't consider myself a professional DevOps: my toolset is limited mostly to AWS solutions. I've been working as a programmer for 14 years. It includes 6+ years with Python and 4+ years with Django. Here's the shortlist of keywords from my experience for the last couple of years: Python, Django, AWS (including Lambda), Heroku, Docker, ElasticSearch (ELK), PostgreSQL, MySQL, Cassandra DB, JavaScript, Vue, Bootstrap, Maps (using Mapbox and Google Maps). Integrations with various external APIs. I'm available in messengers, email to discuss the details of your project and create precisely what you expect. Progress can be tracked using Youtrack, Trello, other software of your choice, in other ways such as regular reports. I'm looking forward to collaborating to create the best solution for your needs.

    Hi, my name is Eugene, and I am a professional developer with over 15 years’ experience in the tech/web development industry. During my time doing freelance work, I decided to continue my self-development and assembled a team. I’ve put together a group of highly talented developers which is called the Regulus Team. I wanted to surround myself with intelligent and bright personalities and create a unique brand that offers a better value to clients. Previously, I have held a range of positions ranging from software engineer to CTO. Since then, I have progressed to building and working with large, highly-customized and integrated platforms, becoming an expert in Python, Apache and Nginx configuration, Unix, Typescript, Angular 2+, HTML, coding standards, infrastructure, performance auditing, back-of-house operations, single-page applications, version control, and much more. I absolutely adore writing code and in spite of my vast experience, I spend a lot of time every day learning new languages, frameworks, workflow optimizations, etc. I am trying to code in the best possible manner following the best established world practices. I am able to jump into a new project quickly and creatively solve problems. When it comes to debugging, I have a great eye for spotting bugs. I try to predict all possible complications before a project begins. During my 13 years of experience in all sorts of codebases, I’m able to start and complete work quicker than experienced contractors. Your time is valuable, so I won’t waste it. I am online and available to my clients 24/7 by phone for urgent issues. My mission is to bring you excellent project satisfaction by providing quality and professional work. The list of technologies I frequently use and the level of my experience: - Python (Django, Django Rest Framework, Numpy, Scipy, Sklearn, Wagtail, Reportlab): Senior Level; - Apache and Nginx configuration: Mid-Level; - Unix (prefer Debian-based systems): Mid-Level; - JavaScript: Senior Level; - Typescript: Senior Level; - Angular 2+: Senior Level; - Jquery: Mid-Level; - HTML/CSS/SCSS: Senior Level;
