What I'm looking for

I’m looking to own end-to-end security and distributed systems work—identity-driven access control, reliable data pipelines, and on-call ownership—while setting design standards and mentoring engineers to ship with correctness under load.

I’m a Staff Engineer with 13 years in C, C++ and Go on Linux, focused on networking, distributed systems, and security infrastructure. I take systems end to end—from design and implementation through staged rollout and the on-call pager afterwards.

At Netskope, I own a stateless Go edge service and the C++ forensics path behind it on AWS EKS, driving DLP workload identity via IRSA/EKS pod identity, building a Vault-backed AES-GCM decryption and re-encryption streaming pipeline, and re-architecting the C++ path for asynchronous processing with above 99.9% pipeline reliability. I also set design and review standards and mentor engineers across two teams, and previously led DDoS scrubbing and AAA access-plane work at Imperva and Altran.
