What I'm looking for

I’m seeking backend roles in Spain focused on Node.js and JavaScript, and I’m open to TypeScript and NestJS environments. I’m ready to relocate once visa or work authorisation is approved and require employer sponsorship under Spain’s PAC/HQP route or an equivalent option.

At SHENGXIN Network Technology, I build and maintain production real-time multiplayer game backends with Node.js and Pomelo. I own game logic end to end, including Domino and Monopoly modules.

I design APIs and services for live operations, model MongoDB data with Mongoose, and implement transaction-based purchase consistency with client-safe retry handling. I also support operations workflows through an Express and React admin tool.

I use Jest and TDD to protect backend logic from regressions. I’m seeking a backend role in Spain and am ready to relocate with employer sponsorship or an equivalent work-authorisation route.
