WORK HISTORY
Principal Engineer Product Manager, Aws Commerce Platform @Amazon Web Services (AWS)
New York, NY, US
Led product for generative AI testing at AWS Commerce Platform - public AWS Consoles (browser automation) and internal APIs across a 300+ microservice architecture. RAG, MCP, agentic architectures.Identified the problem through metrics: high cost of test writing (siloed knowledge meant tests took 2+ hours), high maintenance cost (teams reluctant to invest because small upstream changes broke tests), high ticket reassignment frequency (tests didn\'t identify root cause, multiple teams needed to investigate failures, delays in mean time to resolution).Built the business case: we needed better quality tests, faster to generate, with no ongoing maintenance. Evaluated build vs buy.Defined operational metrics: adoption (teams using), usage (tests generated per month), value (tests maintained by automation, hours saved), quality (tests rejected by humans, syntax errors).Created the roadmap: Starlite web app with RAG → pipeline runner → continuous learning to update knowledge base → agent watching ticketing system and executing tests autonomously.Prototyped to win over reluctant leaders. Led prompt and context engineering - dynamic just-in-time contexts. Took the solution from assistant to trust-and-verify to fully autonomous with continuous learning.Used for the July 2025 customer-facing release - 17 work streams across multiple VP organizations. Also used for two regional expansions. Tracked adoption (teams onboarded), usage (tests generated), and value (hours saved) to measure product success.Led the org-wide innovation program (~250 engineers) and supported the parent organization innovation program (~1,200 engineers). Mentored 4 SDEs, 2 SysDEs, and 2 non-engineers across 5 teams.Took part in both annual and out of cycle performance reviews as well as promotion assessments. Responsible for code reviews, architectural reviews, cost reviews, operational readiness assessments and weekly operations reviews.

SKILLS
ABOUT EAMONN FAHERTY
I have 20 years of experience building products for internal and external customers, B2B and B2C. 10 years in cloud, 8 whilst working at AWS. In this time I have worked as a product manager, business analyst, test architect and engineer. I have worked across web, mobile and interactive TV. For the last 10 years I have been focusing on cloud infrastructure products - helping teams provision, govern, and optimize cloud environments at scale.At AWS I started in professional services, co-delivering with customers. I worked backwards from customer pain points to build an open-source project (4 million downloads) that let platform teams provision, configure, and govern cloud environments with governance controls and financial guardrails. Cost visibility, optimization, and compliance at scale. After its success I was asked to lead its evolution into a new managed service in the DevX and modernization spaces.Today I\'m technical and product lead for two platform teams building AI-powered testing tools for 1,200+ engineers across a 300+ microservice architecture. To solve the problem of system knowledge being siloed across geographically dispersed teams - which resulted in tests taking 2+ hours to write and being low in depth - we built AI that lets anyone describe what they want to test and figures out the steps. Test writing went from 2+ hours to 20 seconds and test maintenance is now fully automated.I can do this because I know where the friction is. In addition to using my own experiences as an engineer I dig into the data deciding what to measure and how to track it. I talk to the teams to understand where they are and what the pain points are.I find the real opportunity - not the symptom, the source. I roadmap. I ship iteratively. Each release proves we\'re solving the right thing because each release solves part of the problem.
