Krueger | Product engineer
I turn messy product ideas into systems people can trust.
My edge is not just shipping interfaces. It is shaping the route map, the hierarchy, the visual language, and the product story so the thing feels coherent the first time someone touches it.
I like startup-stage products where the UI still needs a point of view. Recent work spans Kineo, a premium health and coaching system, and SimDex, a live market product built around scanning, wallet context, and action-adjacent surfaces.
Kineo
Guided health system
SimDex
Live market arena
About
I work where product strategy, interface systems, and frontend execution all have to stay connected.
Shape the product, not just the UI
I define route roles, motion language, conversion surfaces, and interaction hierarchy alongside the actual build.
Early and fast-moving teams
I do my best work when the product thesis is still sharpening and the frontend has to help clarify it, fast.
Mobile wellness to trading surfaces
Kineo and SimDex show the range I care about most: calm guided systems on one side and dense operational surfaces on the other.
Founder-style bio
I like products that need taste, structure, and speed at the same time.
That usually means the work is not just component implementation. It is deciding what deserves a route, what deserves a system, where the premium story lives, and how to make the whole thing feel more inevitable than improvised.
Featured systems
Separate product stories, each with its own rhythm and visual logic.
Kineo
Premium health, coaching, and nutrition in one guided mobile loop.
Kineo combines onboarding, dashboard, workout, grocery, scanner, settings, customization, paywall, and profile surfaces so the product reads like one family instead of separate utilities.
- React + TypeScript web shell with route-specific product surfaces
- Expo mobile app with coach, fuel, scan, store, and profile tabs
- Premium conversion routes tied directly to daily-use loops
SimDex
Live market tooling with a darker, faster, more operational edge.
SimDex pairs a FastAPI backend with a browser-based trading surface, Dex Mode, wallet context, social draft generation, and public company pages that explain why the product is different from a generic scanner.
- Live board, Dex Mode, company route, and why-SimDex positioning layer
- Runner scoring, trade quote preview, auth, bookmarks, and social draft APIs
- Noir interface system tuned for dense signal and action-adjacent UX
Build style
I like products that are visually intentional, structurally clear, and hard to confuse with templates.
Atmosphere matters
Motion, contrast, and surface treatment should reinforce the product story instead of acting like decoration.
Routes should feel purposeful
Each screen needs a job, a hierarchy, and a reason to exist inside the wider product system.
Proof beats adjectives
Real screenshots, real route maps, and product-specific framing beat generic portfolio language every time.

Pick the product world you want to walk through next.
Direct contact
Open to product, frontend, and launch-system work where the interface needs a point of view.
