Yevhen U.

Senior Full-Stack Engineer | Angular, TypeScript, Node.js, RxJS

Senior full-stack engineer with 10+ years building web applications with Angular, TypeScript, and Node.js. Most recently at ClickUp, where I worked on core product features used daily by millions of users, followed by modernizing the Angular frontends of a B2B SaaS platform. Before that, 8 years as a founding engineer and team lead at a US-based property management company, building everything from internal back-office tools to user-facing apps and mobile products. What I can help with: - Angular apps: dashboards, admin panels, data-heavy tables, configurable UIs, design systems - Modern Angular and state management: standalone components, signals, NgRx (including SignalStore), RxJS - Node.js and REST APIs, SQL and MongoDB - Frontend architecture: monorepos (pnpm, Turborepo, Nx), shared component libraries, Tailwind CSS, i18n, legacy migrations such as Angular Material to Tailwind and CDK - Testing and delivery: Playwright E2E, Jest and Vitest, CI/CD with GitLab CI, Docker - Technical leadership: architecture decisions, code review, mentoring I care about the outcome, not just closing the ticket. I'll flag when something doesn't add up and suggest a simpler path. Examples of similar work are in my portfolio. Send me a short description of your project and I'll reply with questions or a first plan.
