Senior frontend developer crafting scalable, performance-first web apps.

What I'm looking for

I’m looking for a senior frontend role where I own architecture, build scalable React/TypeScript systems, and ship high-performance, maintainable features for data- and geospatial-heavy products in distributed teams.

I’m a Senior Frontend Developer with 8 years of experience building complex, data-driven web applications. I specialize in designing scalable frontend architectures with a strong focus on performance, maintainability, and developer experience in long-lived production systems—especially in distributed teams.

At TranscendWater Ltd., I re-architected a complex geospatial module by migrating to the Google Maps API, reducing the codebase size by ~25% while expanding functionality. I also refactored a legacy form engine into a fully dynamic, API-driven system that supports large schemas and eliminates frontend dependencies for backend-driven changes.

I’ve owned key parts of the UI architecture—rebuilding internal admin modules with modern React + TypeScript patterns and introducing TanStackQuery for standardized data handling. I built and maintained a reusable internal component library and design system, mentored frontend trainees and backend engineers, and delivered UI modernization work across legacy Angular/React surfaces.
