At tiket.com, I led frontend and backend engineers across the hotel ecosystem, setting technical direction and supporting architecture, code quality, mentoring, and delivery.

I architected and developed core parts of tiket.com’s hotel booking platform for B2C, B2B, supplier, and internal applications. I also led modernization of legacy PHP applications using React, Next.js, Node.js, Java, and Go.

By strengthening code review, automated testing, and development practices, I contributed to ~70% fewer defects year over year. Architecture improvements, reusable components, engineering standards, and streamlined workflows improved development velocity by ~50%.

As a freelance developer for XYZ GOAT Japan, I built a Web3 NFT platform with React.js, Next.js, and Node.js, including wallet, metadata, and blockchain integrations. Independently, I’m developing CuanHero, a trading automation platform, and ALUTHRA, a fantasy RPG card game.
