About Oleksandr

Job Success
Kyiv, Ukraine - 10:01 pm local time
I am an Angular Developer with a 100% Job Success Score and 1,300+ hours on Upwork, specializing in building scalable web applications with Node.js and NestJS, and integrating AI solutions that solve real business problems. My work spans enterprise dashboards, healthcare platforms, e-commerce systems, and IoT applications - delivered end-to-end with clean architecture and consistent communication.
As an Angular Developer, I have worked across the full version history - from Angular 2 through Angular 21, including complex migrations from Angular 6, Angular 7 through to the latest version. As an Angular Expert, I build high-performance SPAs using PrimeNG, Angular Material, NG Zorro, and NGX, managing state with NGRX, NGXS, Signals, and RxJS depending on what the project demands. I am also a contributor to the PrimeNG library, which means I understand Angular UI architecture at a level that goes beyond typical implementation work. For SaaS product teams, this means fewer regressions, less time on bug fixes, and more time shipping features that matter.
On the Node.js and backend side, I design RESTful APIs with NestJS and TypeScript - handling authentication, SSO, role-based access, WebSockets for real-time functionality, and server-side logic built to stay stable under production conditions. As a Node.js Developer, I work with both monolithic and microservices architectures, using MySQL, PostgreSQL, and MongoDB for data, Docker and CI/CD for deployment, and integrations with AWS, Google APIs, OpenStreetMap, Stripe, DeepL, and Google Translate where the product requires it. I design APIs that are intuitive for frontend teams to consume — reducing back-and-forth and speeding up development cycles.
AI integration is where Angular development and Node.js backend work come together in the most interesting way. I have built RAG systems using LangChain, OpenAI API, and Weaviate as the vector database, as well as AI-powered chatbots and transcription features using Azure Document Intelligence — all within real client projects in the IoT and healthcare industries. I use Claude Code, Cursor and LLM tools actively in my own development workflow to ship features faster, while always reviewing and validating output manually to ensure security, maintainability, and code quality.
This approach has also allowed me to step into polyglot environments - fixing bugs and shipping features in .NET, Python, and PHP codebases at a level that meets production standards, even outside my primary stack.
What sets my work apart as an Angular Developer and Node.js engineer is my QA background. I write with edge cases, validation, and error scenarios in mind from the first line - so your application works under real conditions with real users, not just in a demo. This reduces debugging time significantly and increases your speed to market.
Over 25+ projects for US and EU clients, I have learned that clean architecture and proactive communication matter as much as the code itself. I take full ownership, keep you updated without being asked, and do not need hand-holding to move forward.
