Summary
👤
Senior🎓
Top SchoolKarl Appel is a Senior Software Engineer and two-time founder with 11 years of hands-on experience building full-stack and embedded systems from microcontrollers to cloud at-scale deployments. He blends practical machine learning (RNNs and LLMs) with IoT engineering—designing AWS-based real-time pipelines that supported tens of thousands of devices—and has shipped production React/Electron UIs and APIs backed by MySQL. Karl led the technical build for an analytics-style e-commerce platform early in his career and later developed leak-detection ML for FlowActive, contributing to $1.25M in SBIR funding. Comfortable across C, Python, JavaScript and SQL, he’s equally at home prototyping scraping/NLP workflows as he is optimizing backend performance. His background includes competitive IR research (NIST STIRS) and a mix of entrepreneurship and applied research that makes him a pragmatic problem-solver who thrives on owning end-to-end systems.
