Prabhubalaji Ragavan — Technical Program Manager

About Me

Building programs that ship. Building products that matter.

I'm a Technical Program Manager with 15+ years defining and driving large-scale, high-complexity engineering programs across consumer marketplaces, cloud platforms, distributed systems, and AI initiatives.

My career spans industry leaders — Amazon, Apple, and eBay — where I've shaped technical strategy, established org-wide execution frameworks, and unblocked engineering teams to accelerate velocity. I thrive in ambiguous, fast-paced environments where the playbook doesn't exist yet.

Beyond the program org, I'm a builder. I created HirePrep — an AI-powered career platform built from zero using Claude and VS Code — that's already delivered 2K+ resume reviews and 200+ voice mock interviews.

Outcome-Focused

Every program ties to measurable business outcomes, not just delivery milestones.

AI-Native

Hands-on with LLM-based agents and agentic workflows to automate program operations at scale.

Hypothesis-Driven

Test assumptions fast, learn from data, and pivot before waste accumulates.

Builder Mindset

From org-wide programs to live AI products — I execute at every altitude.
