AI-AugmentedBackendEngineer
Puan Putri Saqinah Firdaus · Jakarta, Indonesia
Building cloud-native systems from Jakarta. Java/Quarkus microservices and AI-integrated APIs shipped at GenAILabs and Fajri Inc.
"I build the systems Tony Stark would deploy: reliable, fast, and a little dramatic."
Systems thinker. API builder.
Backend engineer with production experience across enterprise services and AI-powered SaaS, covering everything from schema design and business logic to Docker containers and cloud deployments. I own services end-to-end and I like it that way.
Deeply interested in AI-augmented development: LLM APIs, retrieval pipelines, and backend infrastructure that makes AI products reliable at scale. Tony Stark didn't outsource the arc reactor. I don't outsource the hard parts either.
