MAMukul Agarwal
Principal product designer @ Roblox
About
Principal product designer at Roblox, prev. at Amazon and High Fidelity (startup). I have worked at startups all the way to a FAANG company: I led the design team responsible for $1.2 Billion in annual revenue at Amazon, leading design for all platforms at Roblox (Mobile, Web, Console, VR), and was the founding designer of a startup with $73MM in funding. My work exists at the intersection of 0-1 products, systems thinking and building for scale. I hold 7 US patents, and my work has been featured in Forbes & The Washington Post. I've done 100+ design interviews at companies like Roblox. Let's talk about how I can help.
How I can help
I bring the perspective of someone who has been on the other side of hiring decisions for early career to Senior IC designers. I can help early/mid/senior product designers with: • Portfolio storytelling and visual design • Mock interviews and portfolio presentations • Executive presence, stakeholder influence, and getting ideas shipped • Building scalable AI prototypes that don't break in front of executives Expect direct, kind feedback, clear prioritization and concrete next steps to level up as a designer. I will be your biggest champion and can make you believe your next goal is way easier than you think.

A hard problem I've navigated
My career has spanned a bunch of situations including being laid off, passed over for promotion, had imposter syndrome, been the first or only designer, survived multiple re-orgs at big and small companies. I will pull from my real experience rather than speaking in generalizations.
