A new home: the target model for the courier experience

Reframed the home screen from a collection of widgets into the target model for a courier’s everyday work.

Outcome: The concept passed qualitative and quantitative validation, and all home-screen states were handed off to engineering. I’ll add the final results after the data has been verified.

Goals: a courier motivation system

Designed a motivation tool that makes the rules clearer for couriers and supports operational goals.

Outcome: The experiment increased hours worked by 9.5% and orders per courier by 10%. The solution was also planned for reuse by other units.

Slot recommendations

Connected courier preferences with the business need to cover demand in the right locations and time windows.

Outcome: In the experiment, fill rate increased by 1.5 percentage points; hours worked per courier rose by 7% in the Top wave and 7.5% in the Gold wave.

A new delivery and multi-order flow

Turned fragmented delivery stages into a clear journey that also works for multiple simultaneous orders.

Outcome: After launch, pickup time fell by 10 seconds and CTE by 20 seconds. The team also received positive courier feedback.

A courier app built from zero in one month

Designed the core journeys for a new courier app in one month while handing them to engineering in parallel.

Outcome: The app rolled out to every courier at the first client and powered real deliveries. Before launch, an A/B comparison showed CTE 5–10 seconds lower than Yandex Pro.

Partner portal: strategy → MVP

Translated the back-office strategy into a target product vision, then carved out a realistic MVP.

Outcome: I established an aligned target vision, defined the MVP, and mapped the product areas needed for a future employee transition. Full user migration had not taken place by the end of this phase.

Autopricing and assortment: from Excel to product

Designed tools that move complex category-manager work from spreadsheets into managed product workflows.

Outcome: The first users started using Autopricing, and the implemented journeys enable managers to move their work out of Excel. FTE reduction remains an expected rather than measured outcome.

Prototype as a sales tool

Turned one-off partner demos into a repeatable prototyping system.

Outcome: Two of four prospects became partners. The sales team says prototypes make the offer more tangible and improve the chance of a deal; I do not claim direct causation.

A modular WMS strategy

Created a target model for splitting WMS into products that can be developed and sold independently.

Outcome: I completed the concept and designs, with UX validation planned as the next step. Implementation had not started at this stage, so there were no implementation metrics.

Kitchen in the order flow

Integrated kitchen work into the wider order flow across different production models.

Outcome: The experiment across eight stores reduced assembly time for kitchen orders by 10% and showed a 0.05% increase in GMV. Both results apply to the experimental sample.

Product model and content automation

Developed the data model and tools that scale content and category operations, rather than a collection of isolated screens.

Outcome: I developed the functionality over several iterations and established a foundation for more manageable content operations. At this stage, we did not measure the quantitative impact or time savings.

Flueno — AI language practice

Short AI dialogues for practising real-life conversations. The product is live in the App Store.

Outcome: The product is published in the App Store and available for iPhone and iPad.

Slotty.gg — find available courts

A live web service for finding available court times in Belgrade.

Outcome: The service is live at slotty.gg and shows current court schedules in Belgrade.
