Hi, I'm Prajwal

An AI engineer based in California. I build AI agents and the developer tools around them, right now emberd, a runtime that runs untrusted AI-agent code inside isolated microVMs. Before this I spent three years at Opslyft on cloud cost and reliability systems, then a Master's on adversarial ML and Android malware detection. I'm open to full-time AI engineer, backend, and full-stack roles.

Re-Evaluating Android Malware Detection: Tabular Features, Vision Models, and Ensembles

Hosahalli Dayananda, P.; Chen, Z. · Peer-reviewed, Electronics (MDPI), 2026

Compares tabular features, visual byte-plot images, and ensemble strategies for Android malware detection. Evaluates where modality choice changes the detection surface and where ensembles actually pay for themselves.
