What I'm looking for

I seek a role where I can modernize frontend architectures, mentor engineers, partner with Product/Design, and deliver accessible, high-performance web applications while growing in technical leadership.

I am a Senior Full Stack Developer with over seven years building production-grade SaaS platforms and logistics applications, focused on React, TypeScript, and modern frontend architecture. I combine curiosity, emotional intelligence, and a mastery of detail to deliver high-performance, user-centered web experiences.

At Atrium Campus I modernized frontend architectures, introduced type-safe RPC integrations, and improved testing reliability with Vitest and Playwright while mentoring junior engineers and partnering closely with Product and Design to build AI-assisted components and scalable dashboards.

Across prior roles I designed real-time UI modules, implemented data visualizations with D3.js, built CI/CD pipelines, and delivered modular component systems. I prioritize accessibility, performance optimization, and developer ergonomics to transform complex challenges into elegant, maintainable solutions.
