Backend Engineer building production APIs & AI-powered tools | Node.js, PostgreSQL, Redis, AWS, LLMs

About

I’m a backend-focused software engineer working on production systems, not demos. At my current role, I build and scale SaaS infrastructure for Amazon sellers, handling high-volume scraping pipelines, API-driven ingestion, background job orchestration, and LLM-based policy evaluation across multiple marketplaces (US, UK, CA). I’ve worked on systems processing 10k+ reviews per day, improving reliability, throughput, and latency. Outside work, I build backend side projects like a URL shortener with analytics and AI-assisted products that combine structured data with LLMs for real user workflows. I enjoy designing APIs, modeling data, optimizing backend performance, and using AI tools pragmatically to ship faster without compromising system quality. Tech: Node.js, PostgreSQL, Redis, BullMQ, AWS, Docker, LLM APIs, RAG
