I'm Yoga Arya Nudatar (Goy), a Lead UI/UX Designer with a product management background in B2B and government e-procurement. I work hands-on and with my design team to translate product requirements into user flows and interfaces, carrying the work through UI/UX quality assurance.
From Mbizmarket, a B2B and government e-procurement platform: one feature I designed solo, one I led end to end, and two I delivered with my team. Side projects are further down.
A request-for-quotation and negotiation flow for government buyers. The comparison screen brings quote details and procurement requirements into one place, and the two-vendor minimum is shown where the buyer acts.
Extended the booking experience to support hotels alongside flights, inside the same trip, approval and document trail.
Buyers can request quantity changes on an existing PO, with seller approval and a recorded change history.
Recipient-based sharing with clear access and deletion states, with consent recorded before anything is uploaded or shared.
I use Claude Code to build HTML prototypes and to check them against the live product. What it produces is a draft: the design decisions, the review and what gets corrected stay with me. Here is one documented example.
This portfolio too: Claude Code did the typing; I made the calls and checked each claim against its source.
What I build when nobody's handing me tickets: a ride-app prototype for my crew and a cycling apparel brand in the making.

Group rides where nobody gets left behind.
A ride-app concept for my own cycling crew: start a group, pick a route, see everyone on the map, then post the ride. I took it from Figma to a clickable prototype with Claude Code. It's a prototype, not a released app, and it's no longer in active development.
It started as a Garmin watch app (a Connect IQ bike computer running in the simulator), then I went phone-first so the whole crew could join.
Bulak Balik CyclingA cycling apparel brand I'm building. Playful and anti-race-team, made for kids on push bikes and the parents who ride with them. I do all of it: the logo, the graphics, the mockups, and a landing page with a 3D jersey you can flip and recolour. The first collection is still coming soon.
Five years at Mbizmarket, one domain, two hats. As a product manager I wrote the PRDs, and because I couldn't wait for a mockup, I designed the screens myself. In 2024 that habit became the job.
Four years of reading regulations, running audits and working with government teams. Same muscles I use to design compliance into a flow today.
I've spent five years in one of the trickiest corners of Indonesian tech: procurement for companies and government institutions. As a PM I learned why the rules and approval steps exist. As a designer, I try to make those rules clear on screen, so people can focus on the job they came to do.
Good design here is rarely about bold visuals. It's flows that follow the rules, treat every vendor fairly (small businesses included), and make sense to people who'd rather get back to their actual job.
