In my previous role at a startup, I was the sole Android Engineer responsible for the native mobile apps. I had the opportunity to create a new Android app. It was an app that allowed warehouse workers to scan barcodes on packages to create an electronic chain of custody. The client who requested this app was happy with the results. I exceeded expectations by delivering the app ahead of schedule (2 weeks vs. 1 month). The necessary features were in place, and the app was user-friendly. https://play.google.com/store/apps/details?id=ai.beans.isp.scan

Cover image for I recently watched a video
I recently watched a video of someone going on a trip to see the Northern Lights. At the end of the video, the person showed a timelapse of the Northern Lights, and I was in awe. Given the holiday season, I was curious to see what a Christmas tree under the Northern Lights would look like. I was able to find the following image (https://media.istockphoto.com/id/2224224036/photo/aurora-borealis-northern-lights-over-christmas-tree-strong-aurora-storm-yellowknife-northwest.jpg?s=612x612&w=0&k=20&c=1folij9hCKe3GGvXlHLu171g2uR_zUl52KZmNsGufPI=). I used this image as inspiration to create a festive EDM song on Suno: https://suno.com/s/y8UK3O8PNWftC0E9 With these themes in mind, I had Lovart generate a holiday card (second image in post). From me to you, Merry Christmas & Happy Holidays Hope you enjoy the song 🧑‍🎄

Storyluxe is a social design app that made polished, editorial story templates accessible to millions of creators. I worked across product design, native iOS implementation, template and editing workflows, subscriptions, growth, QA, App Store presentation, and release support. The project shows my ability to ship consumer creative tools at scale: translating a strong visual brand into an intuitive mobile editor, refining monetization and onboarding, and supporting a product used by millions.

Cover image for I built Runrate's design guide
I built Runrate's design guide in HTML by describing it to Codex in natural language instead of starting in Figma. It still covers what I would normally organize in a Figma library: - semantic color tokens and themes - typography, spacing, shape, elevation, icons, and motion - accessibility and responsive behavior - reusable components with states, usage guidance, anti-patterns, and live examples - product patterns for the ledger, accounts, forms, navigation, and risk or recovery states - guidance for translating the same intent between Web and iOS The difference is that these are not static frames. The tokens are implementation contracts. The components can be used in the browser. The patterns include real constraints, interaction behavior, and accessibility. Production Web remains the source of truth. Then I point the project's AGENTS.md file at the guide. The instruction is essentially this: Before creating or changing a customer-facing Runrate surface, consult the design guide. Use Foundations for tokens, hierarchy, and voice. Use Components for behavior and states. Use Patterns for composition. Reuse the existing system before extending it. That applies to new product features, email templates, marketing creative, and anything else that should match the guide. So the design system is not only a library.... it becomes part of the context used to generate the work. https://myrunrate.com/design What do you think about this? And are you making your design system readable by agents? Curious what other people are doing.

Cover image for LUXE Studio is a photo
LUXE Studio is a photo and video editing app built around focused tools instead of one crowded editor. I worked across product design, native iOS implementation, subscriptions, QA, localization, App Store presentation, and release support. The project shows my end-to-end mobile product workflow: shaping the app experience, shipping polished editing features, refining launch assets, and supporting the product through release.
