Technologies & Tools
Technologies I work with every day
What I do?
I specialize in building modern, scalable web applications with a focus on Angular and cutting-edge technologies. From crafting responsive UIs to integrating AI and real-time features, I ensure robust, maintainable code that delivers seamless user experiences.
With expertise in both frontend and backend development, I bridge the gap between design and functionality—optimizing performance, state management, and deployment workflows for startups and enterprises alike.
Frontend Development
I build dynamic, high-performance interfaces using Angular, RxJS, and state management (NgRx). My focus is on clean architecture, reusable components, and pixel-perfect responsiveness.
Full-Stack Solutions
From RESTful APIs to real-time microservices (Node.js, WebSockets), I develop end-to-end systems with scalable backends, databases (SQL/NoSQL), and seamless frontend integration.
AI & Cloud Integration
I leverage AI tools (OpenAI SDK) and cloud platforms (Azure, Docker) to automate workflows, enhance apps with smart features, and ensure smooth CI/CD deployments.
