Chi sono
Backend engineer, 4+ years with Node.js, NestJS and Ruby on Rails on GCP and AWS.
Right now I keep a live booking platform stable at around 10,000 concurrent users: Redis caching, SQL query tuning, and a database-level fix for double-booking. I have also led a backend team of 5 on a microservices platform, and shipped Stripe, PayPay and Fincode payments.
Best fit for: new REST or GraphQL APIs, fixing slow or broken Node.js backends, payment gateways, Cloud Run and AWS deployment.
Send me your repo or error log and I will tell you honestly if I can help.
