I’m Zareen Khan, a Site Reliability Engineer and DevOps leader focused on reliable platforms, thoughtful automation, and making complex technology easier to learn.
RELIABILITYABOUT
Hey there, I’m Zareen Khan, a passionate and results-driven Site Reliability Engineer (SRE) and DevOps engineer with 11+ years of experience building reliable, scalable systems. I have spent 4+ years at Cisco, contributing to the reliability, scalability, and performance of critical platforms.
My professional journey includes roles at leading organizations like Comcast, McAfee, and CVS Health, where I developed a strong foundation in DevOps practices, CI/CD pipelines, cloud platforms, infrastructure automation, and system monitoring.
With more than a decade of hands-on engineering experience, I focus on practical solutions that make systems easier to operate and teams more effective. Based in the vibrant California Bay Area, I am deeply passionate about technology and its power to shape the future.
My commitment to sharing knowledge is at the core of my mission—empowering others to grow and succeed in their careers. I’m dedicated to driving operational excellence, fostering a culture of reliability, and continuously learning.
SELECTED WORK
Projects shaped by reliability, automation, and a bias toward useful outcomes.
An interactive learning-roadmap platform for Cloud Engineering, DevOps, SRE, Platform Engineering, and Software Engineering. Learners follow chapter-based curricula, use notes and cheat sheets, and track milestone progress.
Explore ZK’s OpsPath ↗A self-paced learning platform inspired by my experience supporting my children’s studies. Students follow grade-level roadmaps, practice original questions, track mastery, and build daily learning habits for SAT and AP preparation.
Explore SAT & AP PrepPath ↗A consent-first digital wellbeing platform that helps families understand device habits without invasive surveillance. Parents invite and connect with their children, while the child stays in control through explicit consent and a paired browser extension. ParentPulse shares privacy-conscious, category-level activity and time summaries—not screenshots, messages, keystrokes, or page content—so families can have healthier conversations about focus, balance, and online safety.
An eBPF/XDP-powered demonstrator that turns abstract Zero Trust into visible per-flow decisions. A BCC-based kernel program parses five-tuple network flows, checks a deny-by-default policy map, and updates allow/deny counters that Python can print or expose to a UI. The safe demo mode acts as a Zero Trust lens without dropping traffic, making it practical to run on a laptop or VM while teaching how Cilium-style policy enforcement works.
An accessible health-information companion that turns user-provided symptoms and context into preliminary, plain-language insights and suggested next steps. A React interface and Flask API orchestrate OpenAI and locally hosted Ollama models, with a modular design for future model integrations. The project emphasizes empathetic UX, responsible handling of sensitive information, and clear boundaries: it is educational guidance—not a diagnosis, a substitute for a qualified clinician, or emergency care.
AICodeMate is an AI-powered code-review assistant that evaluates source code with OpenAI GPT-4 and locally hosted LLaMA models. It detects bugs, suggests improvements, generates a software bill of materials (BOM), and checks open-source licenses through a clean React UI and Flask backend. Python concurrency enables parallel processing, while an optional NGINX setup supports production deployments. Built to balance cloud and local inference, AICodeMate turns review feedback into actionable guidance and is designed for future GitHub pull-request integration, security scanning, and review analytics.

Monitoring and alerting systems designed to make service health visible with actionable signals and useful feedback loops.

WRITING & TEACHING
Writing has always been a passion of mine. Through books and practical learning experiences, I aim to make complex DevOps, automation, and AI-driven development topics more accessible.
