Summary
👤
SeniorJacob Johnston is a software developer and CS student based in California with 11 years of practical experience focused on backend and systems engineering. He has applied rule-based and ML-enhanced reconciliation to messy multilingual place and contact datasets, achieving high-accuracy canonicalization and producing auditable pipelines for evaluation. At Vivi Dynamics he built reliable ingestion pipelines across heterogeneous EHRs and worked on training and fine-tuning domain-specific models on NVIDIA DGX infrastructure. His interests span security, privacy, FOSS, encryption, and LLMs, and he brings a curiosity for mathematical topics like transcendental numbers and large primes to engineering problems. Comfortable moving between production data plumbing and model tuning, he combines rigorous, measurable results with a taste for research-adjacent tooling.
