I’m a Staff Engineer at Alchemy and a former Tech Lead Manager at Google, with over 10 years of experience building and scaling backend systems, low-latency services, and distributed infrastructure.
At Google, I led a 7-engineer team, optimizing large-scale data pipelines and geo-services, reducing costs by 40% and data staleness from 27 to 7 hours. I also drove Google’s Managed Prometheus integration with GKE, contributing over $14M in ARR.
At Alchemy, I currently lead the development of the 4337 account abstraction infrastructure—powering one of the top bundlers on the market. As Reliability Commander, I revamped our alerting and observability system, cutting 80% noise and ensuring 5-minute preemptive alerting.
I’ve conducted 100+ interviews across system design, algorithms, and behavioral rounds at Google and beyond. I offer mock interviews and mentorship for engineers targeting senior, staff, or EM roles, with actionable feedback tailored to your target company.

Session: Introductory Call
5 out of 5 stars
I originally reached out to Andy for help navigating a highly complex interview process. I needed someone knowledgeable to guide me, but I ended up getting so much more than just standard interview prep. Andy has a great intuition for sensing exactly how you need to be coached in the moment. We worked closely together to shape my state of mind, and he gave me the emotional context I needed to handle the pressure. He motivated me on a real, human level to approach these challenges correctly. Thanks to his guidance, I was able to walk into my interviews as the absolute best version of myself. Plus, we had a ton of fun along the way because he is genuinely a great guy with a lovely personality. I would highly recommend him to anyone needing coaching in the tech scene. Appreciate your help Andy! I hope we get a chance to work together someday.
