Expertise:
Klar Mobile Banking
Fintech Startup (Series C) | High-Impact Savings Product
2021–2023
Driven by usability insights, the product achieved its 6-month customer savings goal within the first 30 days of launch, sparking a 3.5x growth in total user debit balances in under two months.
I led the end-to-end product design for Klar’s fixed-term savings feature, "Money Pot" (Inversión), for over 2 million users in Mexico. Accountable for the entire user lifecycle—collaborating closely with cross-functional stakeholders to design within established design systems while actively helping to scale and maintain them.
Bibo App
On-Demand Delivery | Complete Mobile Experience
2021–2022 (Freelance)
Designed the end-to-end iOS & Android experience for a beverage delivery service in Milan and Rome — building the app's design system from the ground up. Crafted essential journeys from login to checkout, alongside scheduled delivery windows and the "Bibo Drink Club" subscription model to maximize lifetime value.
Outcome: Delivered an intuitive scheduled order flow that streamlined operational efficiency outside peak hours and provided strategic subscription architectures to boost long-term retention.
Hangles App
Re-Commerce Marketplace | End-to-End Platform Design
2022 (Freelance)
Owned the comprehensive product design—including user personalization, seller tools, and design systems—for a Bangkok-based secondhand fashion startup. Solved complex operational bottlenecks by translating dense business logistics into seamless, digestible user tracking states for the managed consignment service.
Outcome: Designed a consolidated dashboard mapping the entire multi-week item lifecycle, keeping users clear on pickup schedules, bulk item status, and real-time payout earnings.
Design Philosophy
Design is at its best when it solves for both the user's intent and the business's bottom line.
I specialize in evidence-based product design.
Briefly
about me.
I'm Jan — a Senior Product & Service Designer with 8+ years of experience across fintech, e-commerce, and healthcare. My career started in digital agencies in Bangkok before I pursued a Master's in Service Design at Politecnico di Milano, which shaped how I think about products: always from the user's journey outward, and always with business impact in mind.
I've worked across the full design spectrum — from 0-to-1 product strategy to scaling mature design systems — at companies like Klar Technologies in Berlin, where the savings feature I owned drove 3.5x growth in user debit balance within 60 days of launch.
I specialize in translating complex systems — financial products, multi-sided platforms, regulated journeys — into experiences that feel simple and human. I work closely with PMs, engineers, and researchers, and I care as much about the handoff as I do about the concept.
