Andrew Lehmann

I am a Senior Full Stack Software Engineer with 8+ years building and scaling production-grade web applications for high-traffic consumer platforms and enterprise SaaS. I design end-to-end systems across frontend, backend, data pipelines, and cloud infrastructure, prioritizing performance, reliability, and maintainability.

I've led engineering efforts using React, TypeScript, Node.js, Django, MongoDB, and AWS, integrating AI-assisted workflows and ETL pipelines to reduce manual work and improve data consistency. My work has improved page load times by 20–30%, cut query latency by 30–50%, and reduced manual processing by 30–40% through automation and AI integrations.

I partner closely with product and design to translate ambiguous requirements into scalable solutions, mentor junior engineers, and shape architecture and operational practices that support 99.9%+ uptime and continuous delivery for large-scale systems.
