As a Senior Frontend Architect, I was responsible for defining the overall frontend architecture and driving the technical vision for large-scale web applications. I led the design and implementation of scalable, high-performing, and maintainable UI solutions while ensuring alignment between product, design, and engineering teams. My role involved establishing coding standards, optimizing performance, modernizing tech stacks, and mentoring development teams to deliver consistent, high-quality user experiences across platforms.

Key Outcomes

• Architected a modular and scalable frontend framework that improved code reusability and accelerated development cycles by 30%.
• Enhanced application performance and load time by 40% through efficient rendering, caching, and build optimizations.
• Modernized the frontend stack by migrating legacy systems to modern frameworks (e.g., Angular → React / Angular 12), improving maintainability.
• Implemented a unified design system that ensured UI consistency and reduced development effort across multiple products.
• Established best practices and CI/CD integration, enabling smoother deployments and faster release cycles.
• Mentored and up-skilled frontend teams, fostering a culture of technical excellence and continuous improvement.
• Contributed to cross-functional architectural decisions, aligning frontend strategies with overall product goals and user experience vision.
