01. About me
Hello! I'm Felix Vo, a Senior-oriented Frontend Engineer with over 5 years of experience in crafting high-performance web and mobile interfaces. My journey began with a deep curiosity for bridging the gap between complex logic and elegant design, which has since evolved into a passion for building scalable, user-centric applications.
Throughout my career, I've had the privilege of leading frontend development for mission-critical platforms, including a core project that recently secured $3 million in seed funding. I thrive in cross-functional environments, working closely with designers and stakeholders to deliver premium products on schedule and within budget—even under high-pressure conditions.
I specialize in leveraging advanced technologies like ReactJS and NextJS to build dynamic, responsive ecosystems. My approach is deeply rooted in detail-oriented engineering and staying ahead of the curve with the latest industry standards and design trends.
Here are a few technologies I have been working with recently:
- React 19 & Next.js 15
- TypeScript (Strict)
- TanStack Query
- Tailwind CSS v4
- Zustand & Global State
- Vitest & Cypress
- Performance Tuning
- System Architecture
