Heya! I'm Patrick. Currently at Microsoft doing product-related ML insights.

Nowadays, you can find me at home making my own coffee, tending to my 16+ houseplants, attempting to bake, playing video games with friends on Discord, and obsessively staring at my saltwater nano reef tank.

I decided to leave my role at Amazon to recover from pandemic burnout.

Due to the nature of the role, I'm not able to go into deep detail about what I accomplished there to adhere to confidentiality.

Here's the gist:

  • Designed and developed a serverless Scala API which processed up to 600 requests/second.
  • Owned the ML model refresh process from inception to production to increase precision significantly, making fraud investigator efforts more efficient. I led this project and crafted organized updates with senior manager/director-level visibility.
  • Reduced production fleet CPU utilization by 30% through investigating and culling deprecated workflows.
  • Led and set sprint standards for a team of ~9 engineers, including retrospectives, task estimation and priority planning meetings.
  • Mentored 2 interns and streamlined the team onboarding process, enabling them to build a full-stack web application.
  • Resolved high-severity issues in an on-call rotation and authored runbooks and dashboards to outline production processes and prevent future issues.

Mentored someone
The Amazon Future Engineer (AFE) program aims to increase access to computer science opportunities for underrepresented communities. I had the pleasure of mentoring 2 AFE interns this summer.

Throughout the course of the summer, they were able to hone their technical and soft skills while building a full-stack production-grade application for our team. Though they only finished their 1st year of college before the internship, they continued to impress me with how quickly they picked up new skills.

Though I wish I could’ve met these two in the office (whether for social events or debugging issues), they both raised the bar in terms of the results they delivered. Remote work came naturally for them, and communication issues that I expected to arise were virtually nonexistent.

I learned a lot as well. Juggling my own projects while managing these interns wasn’t easy, so I had to find a balance between ever-shifting project priorities and being available for the interns. I found that dedicating (at least) 30 minutes every day to syncing up on blockers and celebrating small wins was a good system.

I joined Amazon right after my 4th year of university, where I worked on a ML platform that identifies seller risk in support of EU anti-money laundering and counter terrorist financing initiatives.
