Profile: https://flows.cv/erikostman

Senior Software Engineer (6+ years) based in New York, focused on distributed systems, backend architecture, and data-intensive products. I design and build TypeScript/Python services on AWS that power LLM features, data pipelines, and customer-facing applications at scale.At Earned, I’m the lead backend engineer, owning core distributed systems, AWS cloud infrastructure, and LLM-powered product features. Previously, I built and scaled products at early-stage startups across fintech and healthcare, taking platforms from 0→1 and then hardening them for reliability, performance, and growth.

I bring a strong engineering and analytics foundation: an M.S. in Analytics (in progress) from Georgia Tech and an engineering degree (summa cum laude) from UNSW. My work sits at the intersection of software engineering, data engineering, and applied machine learning.

Tech: TypeScript, Python, Node.js, AWS (ECS, Lambda, RDS, SQS, S3, DynamoDB), PostgreSQL, distributed systems, data engineering, ETL pipelines, LLMs, system design, microservices, CI/CD.
