Andrii B.

I am an experienced full-stack developer with a strong technical foundation and a passion for building scalable, high-performance applications across web and mobile platforms. My skill set covers both client-side and server-side development, as well as AI and data-intensive systems. On the backend, I work confidently with Node.js (including Express and WebSocket integrations), PHP, and MySQL, designing robust REST APIs and optimizing relational databases with advanced SQL queries and indexing. I also have hands-on experience with web server administration using Nginx and Apache on Linux (Ubuntu/Debian), including shell scripting, monitoring, and security hardening. On the frontend, I specialize in modern JavaScript (ES6+), React, and Vue. I focus on building responsive, user-centered interfaces using Bootstrap and HTML5/CSS3 (with Flexbox and Grid). For legacy systems, I maintain proficiency in jQuery. I'm also familiar with TypeScript for adding static typing and scalable interface design in frontend projects. I have extensive experience working with geospatial technologies, including OpenStreetMap, Leaflet.js, and GIS concepts such as spatial queries and raster/vector data integration. I’ve developed custom map layers, clustering solutions, and integrated real-time weather data using global models like GFS, ECMWF, and ICON-EU, handling GRIB2/NetCDF formats and visualizing wind, temperature, and atmospheric dynamics. On the AI side, I am a certified developer with a diploma in generative AI obtained in 2025. I have trained and deployed neural networks using PyTorch, including convolutional models (CNN), generative adversarial networks (GAN), variational autoencoders (VAE), and transformer architectures. I also integrate large language models (LLMs) such as GPT, Claude, and Mistral into practical applications like chatbots, document generation, and fine-tuned instructional agents. My mobile development experience includes building cross-platform apps with React Native, following best practices for mobile UX on Android and iOS. This diverse skill set allows me to tackle complex projects that combine web technologies, data processing, and intelligent systems — delivering end-to-end solutions with technical precision and creativity.
