Andrew Killian

I've built and shipped enterprise software at Southwest Research Institute, where I reduced regression testing effort by 43% and automated server communication workflows to save 15+ hours of weekly operational work.

At HomeStead HotLeads, I build responsive websites, marketing funnels, REST API integrations, and automated lead-delivery workflows. My work has improved lead capture rates by 30%, saved approximately five hours per week of manual processing, and maintained 99%+ uptime across client sites.

As a contract AI Prompt Engineer at Handshake AI, I designed multi-turn LLM prompts, evaluation frameworks, and rubric-based test suites across 10+ task categories. I improved task-completion consistency by 35% and reduced API latency by 20% through token optimization.

I work across Python, Flask, automation, REST APIs, CI/CD, and cloud-hosted web products, with experience collaborating in Agile teams and translating requirements into production-ready solutions.
