In this role at 4D, I was responsible for building fast and performant web and mobile apps, primarily using React, Angular, Ionic, and Node.js. My tasks spanned various aspects of front-end and back-end development, as well as optimizing code and application performance.
Key Responsibilities
- Enhanced existing codebases to improve performance, reduce technical debt, and make the code more maintainable.
- Introduced best practices for code readability and modularity.
- Created clean, well-structured codebases that adhered to modern development standards.
- Integrated version control tools like Git for seamless collaboration across teams.
- Conducted performance audits, identifying bottlenecks and improving app performance by implementing best practices in caching, lazy loading, and request optimization.
- Regularly used tools like WebPageTest and Google Lighthouse to ensure optimized performance.
- Created test suites using Jest, Cypress, and React Testing Library to ensure robust and reliable applications.
- Maintained high test coverage and addressed bugs proactively.
Achievements
- Performance Enhancements: Improved app performance, reducing load times and increasing responsiveness by over 35%.
- High Code Quality: Implemented and maintained test-driven development practices, resulting in fewer bugs in production.
- Scalable Solutions: Designed and implemented scalable architectures that were future-proof and easy to maintain.
