    Hello, I am a back-end developer at Regulus Team. My stack is Python/Django. I have experience in different fields of studies. My Ph.D. degree is in computational chemistry. In my work, I dealt with theoretical chemistry, namely the applying of statistical and machine learning methods in chemistry and quantum chemistry. As the result I wrote multiple programs to carry out my research studies; first, in Fortran and after in Python3. As a rule, due to the high computational capacity of programs, their calculation was carried out on Ubuntu servers (in the administration of which I participated directly). - I have knowledge of Django, Django REST framework, PyTest, and git. - I have worked with the following Python packages: Numpy, NeuPy, Scikit-Learn, Rdkit, Chemoffice, I have basic knowledge of Keras. - I have basic knowledge of unit-testing packages, JavaScript I love learning new technologies and improving knowledge constantly. I am a team player and intend to write clean, unbuggy code.

    I develop web apps and sites using Laravel, Vue, Tailwind. My forte is to take over existing PHP project with legacy, performance issues and chaotic development cycles and put it all in order: resolve issues, implement new features, introduce proper code practices. If you have just an idea, I will help create a project roadmap with clear timeline. I like working closely with product owner, only this way I can deliver what you really need, not in the end of project but starting from day 1. I believe good code is one that is easy to change and maintain. If you want to build: - a Marketplace; - a SaaS; - a membership restricted website for something; - a backend for mobile or web app; - API for something; - anything that is not CMS but a web app; let's talk! I like and prefer asynchronous communication on project. However sometimes it's necessary and I will happy to meet you in Zoom. Seeing your idea be successful is more important to me than getting your business, so if you're not certain whether I can help you, contact me, and I'll help you figure out who can. Recent works: - Backend for app - Top-25 in Food & Drinks on App Store Denmark - Crypto prices monitoring system - Ad server - Multi-level marketing and affiliate program engine - Ride-sharing app for drivers and riders 🇺🇦

    I specialize in no-code automation using n8n. In a short time, I've built several working solutions — including an AI-powered assistant with a vector database that handles client conversations 24/7, adapts to the user's communication style and lead type (cold, warm, hot), processes requests via API, calls a human operator when needed, and easily adapts to any business. While the initial implementation was built for Telegram, the project can be adapted to any messenger — WhatsApp, Viber, Instagram, and more. Everything is flexible: logic, knowledge base, and entry points. I’ve also built a Telegram-based interface for operators: client queue, full chat history, access control, and live conversation handling — all inside the same bot. I quickly make sense of complex systems, explain clearly, and focus on results. I avoid unnecessary technical jargon and aim to deliver solutions that just work. I can take on full-cycle projects depending on the task — always with a focus on quality.
