Isaac Rodrigues

Full-stack developer and Computer Science student in Brasília, Brazil, focused on applied AI and cybersecurity. Online, I go by Olwtelet. At Ordfall, I built the corporate website and work on security: vulnerability analysis; code, dependency and configuration review; and support in defining secure architectures, from design to production. At Integratek, I develop the company website (Astro, TypeScript, Docker), with ongoing SEO, performance and accessibility work. I also deliver client websites and maintain open-source projects such as Argus and AgentForge. Core stack: TypeScript, Python, React, Next.js, Node.js and FastAPI.
