At Kon'ya Japan, I provided front-end technical support for a live production website, resolving issues with React, TypeScript, Vercel hosting, and CloverAPI integrations. I also explained technical issues and solutions to the client and worked with API developers and business stakeholders on integration fixes.
As a Freelance Front-End Developer for FuwaFriends, I resolved issues in a live ecommerce checkout workflow and made focused UI/UX improvements. I tested user and checkout scenarios with React Testing Library and followed up with stakeholders to confirm reported issues were resolved.
I developed and tested a secure authentication system using Node.js, Express, MongoDB, JWT, Google OAuth, and HTTPS, then configured its infrastructure on AWS. My hands-on projects also include assembling and troubleshooting custom PCs and configuring network topologies with Cisco Packet Tracer.
