What I'm looking for

I’m looking for global remote roles (Europe/Asia overlap) where I can own backend architecture, deliver scalable GraphQL/Postgres systems, and build pragmatic LLM automation that improves productivity and reliability.

Senior Software Engineer (5+ yrs) specializing in high-throughput B2B SaaS architectures, GraphQL/PostgreSQL performance optimization, and production GenAI workflows. 2x promoted at Toddle, a global edtech platform serving 2,000+ schools across 100+ countries.

Key Highlights:

• 0-to-1 Architecture: Led backend & DevOps for a public curriculum publishing platform, designing safe public-read models with PostgreSQL Row-Level Security (RLS) and public Apollo GraphQL APIs.

• Database & API Performance: Reduced critical PostgreSQL query latency by ~95% (11s to 335ms) across 10M+ row datasets and eliminated N+1 GraphQL query bottlenecks with DataLoader.

• Applied GenAI & Automation: Built production LLM pipelines, including an automated sales follow-up agent saving 20–50 hrs/month and an LLM localization pipeline cutting language rollout cycles to ~1 hr.

Tech Stack: TypeScript, Node.js, PostgreSQL, GraphQL, AWS (Lambda, SQS, S3, RDS), Redis, Python, LLM APIs / n8n.
