I am a software engineer with 15 years of experience with PHP

(Laravel),Python, JavaScript (Node.js, Vue.js, jQuery) languages. I'm working with both SQL and NoSQL databases: MySQL, PostgreSQL, MongoDB, Redis, Elasticsearch. I have led the full-stack development of custom ERP systems with messaging app integration. I created mobile and progressive web apps with purchasing, order flow, and data analytics capabilities. I have also created SMS messaging and voice verification APIs supporting peak loads of 25 requests per second. I am interested in working with non-technical leadership to translate business requirements to software solutions that I design, develop, and support by myself or as a hands-on leader of a small team.

I enjoy full-stack website development and have made dozens of internet-facing websites for my telecommunications business, for e-commerce clients and for my own hobbies and personal projects, such as an audiobook repository and playback client. I am experienced with several frameworks and real-time web technologies. I prefer to work with PHP (Laravel), JavaScript (Vue, Node)
