Arpan Sarkar
I'm a 19-year-old developer who builds production software. Right now I'm an SDE at a startup in Malaysia, building a healthcare and workforce platform remotely.
Before that: a production website and an internal NestJS management platform for a 45-person team at Sequoia Print, plus freelance work spanning a hospital management system live in 2 hospitals, a hiring platform for a US client, and a coaching platform for 500+ students.
Mostly TypeScript, NestJS, PostgreSQL and Redis, with RAG and agent pipelines where they earn their place. 20+ merged PRs across FOSSAsia, CopilotKit and Nano Collective.
