Junior Software Engineer • Frontend-Focused Full‑Stack Developer
Building performant, interactive web experiences with React, Next.js, Node.js, and modern TypeScript tooling.
- 🛠 Full‑stack experience (frontend emphasis) across React, Next.js, Node.js, and modern TypeScript ecosystems.
- 🗃 Strong grounding in data accuracy & workflow optimization (100% data integrity in prior data engineering role).
- 🎹 Passionate about interactive media (audio + 3D + algorithmic visualization).
- 🧪 Practices: incremental delivery, thoughtful abstractions, measurable improvements.
- 🧩 I enjoy turning complex state & transformations into reliable, testable modules.
I build maintainable frontends and full‑stack features that balance performance, clarity, and developer ergonomics. I care deeply about correctness, fast feedback loops, and tangible improvements (speed, reliability, usability).
