I'm Ostap, a Senior Frontend Developer specializing in Angular. Over the last 7+ years I've built and shipped enterprise, fintech, and Web3 applications, most often as the sole frontend owner working directly with the client. My core specialty is Angular across every version from 2 to 21, including full legacy migrations and version upgrades. If you have an older Angular app (v8–v14) that's slow, hard to maintain, or stuck on deprecated dependencies, migrating it to the latest version - with standalone components, lazy loading, and OnPush change detection, signals and etc. - is exactly the kind of work I do. What I can help you with: - Upgrade or migrate a legacy Angular application to the latest version - Build a new Angular app, admin dashboard, or data-heavy SaaS platform from scratch - Add complex features, reusable component libraries, or micro-frontend architecture to an existing codebase - Integrate REST APIs, authentication, and third-party services - Improve performance, accessibility, and responsive design Selected experience: - Built the wallet integration layer (EVM + non-EVM) for Allbridge, a cross-chain stablecoin bridge that has handled 1.9M+ transfers across 24+ blockchains including Ethereum, Solana, BNB Chain, Polygon, Avalanche, and Tron. - Delivered enterprise CRM for one of Canada's largest telecom providers, building role-based interfaces for call-center agents, administrators, and customer self-service portals. - Migrated a monolithic enterprise Angular application into three independent micro-frontends, enabling independent deployments. Core stack: Angular 2–21, TypeScript, RxJS, NgRx / NGXS, standalone components, Angular Material, micro-frontends, Nx monorepos, SCSS/Sass, REST APIs, unit testing (Jest, Jasmine, Karma). I write clean, maintainable, well-tested code and care about the details - performance, accessibility, and interfaces that feel fast. I take the time to understand what you actually need, then deliver solutions that are easy to scale and maintain. If that sounds like a fit, send me a message - I'd be glad to discuss your project.
