About

Hi, I’m Nikko, a frontend-focused software engineer with about 2+ years of experience building AI-powered educational applications.

At 24/7 Teach, I’ve worked on AI-powered learning platforms, contributing across the stack but primarily focusing on building user-facing features and interactive dashboards using React, TypeScript, and Tailwind CSS. I enjoy improving performance, refining user experience, and turning complex requirements into clean, maintainable interfaces.

I’ve collaborated closely with designers, stakeholders, and cross-functional teams, and I’m always open to learning new tools when the project calls for it.
