Harmony Orakpoyovwuru

I’m a Senior Frontend Developer with over 5 years of professional experience specializing in Angular, React, and modern data visualization tools like D3.js and Chart.js. My focus is on building scalable, performant, and user-friendly interfaces for web applications that handle complex data and require clean architecture.

Over the years, I’ve delivered enterprise-grade frontend solutions for a range of domains—from real-time monitoring dashboards to analytics platforms and component libraries. I work confidently with both Angular (v2 to v19) and React, applying best practices in architecture, modular design, and state management using NgRx, NGXS, RxJS, or Redux Toolkit. I’m particularly passionate about turning data into insight through responsive and interactive visualizations, whether with custom SVGs in D3 or dynamic charts in Chart.js.

My typical tech stack includes TypeScript, SCSS, REST/GraphQL APIs, Jest or Cypress for testing, and Git workflows integrated into CI/CD pipelines. I believe in clean, maintainable code and rigorous testing practices, ensuring robust applications that scale. I also have experience leading frontend discussions, conducting code reviews, and mentoring junior developers in cross-functional teams.

Whether you need a frontend expert to craft a high-performance dashboard, optimize an existing Angular application, or build reusable React components for a data-heavy platform, I can help deliver quality software with speed and precision.

I’m currently open to remote or hybrid freelance opportunities across Europe, ideally in projects involving data visualization, real-time interfaces, or advanced UI architectures. Let’s build something impactful together.
