Summary
👤
Senior🎓
Top SchoolJ Deustua is a PhD-trained chemist and software leader with 11 years of experience bridging cutting-edge quantum chemistry research and production-grade engineering. As COO and co-founder of Examol, he builds a tech-bio platform that applies physics-first and AI algorithms to democratize drug discovery for teams of any size. His background includes postdoctoral work at Caltech and deep open-source contributions to the widely used psi4 quantum chemistry codebase, where he has improved core C++ electronic-structure algorithms. He has hands-on full-stack engineering experience from Nuxt/Vue frontends to Flask backends and AWS deployments, and a track record of improving reliability and distributed job performance. Comfortable moving between research, product and infrastructure, he also taught and mentored students and shipped specialized PSI4 plugins during his PhD. An early web entrepreneur and systems admin, he combines practical DevOps instincts with advanced computational science.
