What I'm looking for

I’m looking for a Senior Frontend (with MERN) role where I can architect component-driven React systems, optimize performance, and build design-system quality UI while mentoring teams and collaborating with product and backend.

I’m a highly accomplished Senior Frontend Developer with additional MERN Stack expertise, bringing over 11+ years of experience designing scalable, performant, and visually refined digital products. I focus on performance optimization, user experience, accessibility, and clean code principles across SaaS, E-commerce, Banking, Design Systems, and Enterprise Products.

In recent work, I built mission-critical dashboards, admin panels, and academic management interfaces using React.js, TypeScript, Redux Toolkit, and SCSS. I integrate REST APIs, optimize global state management with Redux & Context, and reduce load times through memorization and code-splitting—while translating complex Figma designs into responsive, pixel-perfect components.

With hands-on MERN stack experience (including three production-grade projects with full backend integration), I’ve collaborated closely with backend teams using Node.js and MongoDB to align API structures with frontend needs. I also strengthen quality by implementing Jest-based unit tests and stability-focused testing practices.

I enjoy leading development teams, architecting component-driven systems, and mentoring through code reviews and engineering standards. I bring practical delivery experience from full UI/UX cycles, sprint planning, and cross-functional collaboration, always aligned with business goals.
