What I'm looking for

I want to build performant, user-centered web platforms using modern frontend tech, mentor engineers, and work in teams that value scalability, security, and continuous delivery.

I am a senior software engineer with deep expertise in building scalable, data-intensive web applications using React and TypeScript. I design modular component systems and engineer performant dashboards and CRM tools that support thousands of daily users.

At Fairmoney Microfinance Bank I led the design and development of a CRM/Business Development tool and redesigned sales dashboards to improve workflows, reduce bundle sizes, and support offline and limited-connectivity scenarios. My work emphasized security, real-time analytics, and reusable UI components.

I have contributed to large open-source projects and gained experience with advanced React patterns, GitHub workflows, and release management while collaborating with global teams. I also led frontend teams to build merchant portals with high availability and CI/CD pipelines.

I seek to join teams where I can continue delivering user-focused, high-performance web products, mentor engineers, and drive engineering best practices across product and platform initiatives.
