Senior Frontend Developer

At BraveOrange, I worked as a Senior Frontend Developer (with full-stack responsibilities) building enterprise-grade web applications for diverse clients across finance, e-commerce, and logistics sectors. My role encompassed the complete software development lifecycle from requirements analysis and technical design through implementation, testing, deployment, and maintenance.

On the frontend, I architected and developed modern React applications using Next.js 14 with the App Router, implementing server-side rendering (SSR) and static site generation (SSG) for optimal performance. TypeScript was used extensively for type safety, reducing runtime errors by 40% and improving developer productivity. I built responsive, accessible UIs with Tailwind CSS and implemented complex state management using Zustand and React Query for efficient data fetching and caching.

Backend development involved building RESTful APIs and microservices using Java 17 with Spring Boot 3, implementing clean architecture patterns with clear separation of concerns. I designed PostgreSQL database schemas with proper normalization and indexing, wrote comprehensive tests with JUnit and Mockito achieving 85%+ coverage, and integrated third-party services including payment processors (Stripe, Mollie) and authentication providers (OAuth 2.0, JWT).

I established robust CI/CD pipelines using GitHub Actions and GitLab CI/CD, automating testing, code quality checks with SonarQube, and deployments to AWS (EC2, S3, RDS) and Azure environments. Docker containerization ensured consistent environments across development, staging, and production.

Collaboration was key - I worked closely with UX designers implementing pixel-perfect designs with Figma hand-offs, partnered with backend teams on API contract design and integration, mentored 3 junior developers through code reviews and pair programming, and participated in agile ceremonies including sprint planning, daily standups, and retrospectives. This role significantly enhanced my full-stack capabilities and enterprise software development expertise.
