Summary
👤
Senior🎓
Top SchoolJosé Sachs is a security-focused full stack developer with 12+ years of experience delivering secure, scalable web and mobile applications while consulting for international clients from ANIMUS Coop. He combines deep hands-on skills in NodeJS, Rust, MongoDB, Vue and Svelte with a pragmatic offensive security practice, having discovered complex vulnerability chains that led to cloud compromises (AWS/GCP), RCE and mass PII/API key exposures. José partners directly with engineering and executive teams to remediate high-impact issues, turning findings into long-term consulting relationships and multiple high-value bounties. Comfortable across R&D, frontend redesigns and app development, he brings both developer velocity and a security-first mindset to product teams. Based in San Carlos de Bariloche, he pairs formal computer engineering training with a history of server administration and responsible disclosure work that few full stack engineers combine.
