Building Teams Under Constraints

Head of Product Design and UX, Position, 2017-2019

The Challenge: Joined a “product built of steel,” where every communication and design change required months of approval, and engineering often deemed requests impossible. Navigating stringent constraints involving FICO scores, credit lines, and debts, there was no room for microcopy within the product or for building user funnels inside the interface.

My Approach: Turned constraints into creative momentum by finding innovative solutions within technical limitations. Complex problems fuel my passion for design!

Team Building: Established and structured the design department, building its culture and operations across two time zones with a mix of Israeli and San Francisco-based designers to address capability gaps. Recruited continuously to meet the challenges of San Francisco’s highly competitive design talent market.

Impact: Developed a cohesive 7-person design team, including an essential UX writer. Established a design voice that influenced company-wide branding decisions. Became a strategic partner in roadmap building. Reported directly to the COO and was empowered to transform the company’s approach to UX and its organization.

Employee Onboarding Product: Identified a company-wide challenge where new employees remained silent for months due to confusing fintech terminology. Created a comprehensive dictionary of industry terms with an integrated update process involving all department leaders. This knowledge management system was installed across all company Macs and, to my knowledge, remains in active use.

AI Powered Receipt Management

Product Lead & Hands-On UX Design, Project, 2022

The Challenge: Transform a B2B SaaS platform to help users efficiently browse and manage thousands of receipts—while solving a critical onboarding drop-off caused by trust concerns around granting full mailbox access to an AI system.

My Approach: Drove roadmap development together with the CEO while designing hands-on in Figma. Redesigned the core product experience from the ground up.

Key Innovation: Created a guided, graduated onboarding funnel while redesigning the core interface with Gmail-familiar patterns and systematic color-coding for faster workflow navigation.

Impact: Delivered a comprehensive platform transformation that simplified complex workflows and significantly improved onboarding completion rates.

RemindMe app - Coming Soon!

Independent Product Endeavor, 2025

The fastest way to turn fleeting thoughts into calendar reminders — quicker than Google Calendar.
Designed for speed and focus, RemindMe helps busy people schedule reminders fast to get things done.

The Challenge: Standard reminder creation involves too many steps and clustered screens, causing busy people to lose their train of thought or skip capturing important tasks altogether.

My Solution: A streamlined tap > type > schedule flow that gets you back to what you were doing in seconds. No navigation maze, no friction. You can even preset default times or invite your spouse with a tap — so they remember to pick up the laundry.

My Role: Conceived, designed, and managed a cost effective development process, working with a skilled development team via Upwork to bring this utility to life.

Personal Motivation: Sometimes designing for yourself leads to solutions others need too.

Always in Action
Anticipating User Needs

Entrepreneur, 2015-2017

After managing a PC utilities software portfolio and overseeing cart and ePayments management, I launched my own initiative designing innovative utility software that simplified complex user processes, essentially pioneering what Chrome suggests today, back in 2015. My vision was to enable efficient device usage when most users struggled with basic functionality.

The Challenge: PC users needed shortcuts for complex processes.

My Solution: Designed toolbar utilities that reduced multi-step actions while enabling automated execution of commonly needed functions.

Business Innovation: Designed a chargeback protection strategy using separate transactions to bundle my own low-cost utility products (recurring $2–3) with premium downloads. By isolating utility transactions from higher-risk premium sales, this approach protected merchant reputations from chargeback penalties while enabling cost-free distribution of my products through established merchant networks.

Result: Developed a complete product portfolio and generated waiting list of customers, digital merchants and payment aggregators. Development paused when Windows 10 transformed the downloads industry.

Recovery time: longer than I'd care to admit.

The Challenge: Transform an investment-winning presentation into a functional MVP, transitioning from concept to buildable product.

My Role: Led user journey mapping workshops collaborating with an early payments product manager and development team during the company's pre-scale phase.

Approach: Facilitated cross-functional sessions to map detailed user flows and communication touchpoints for target customers, ensuring MVP design focused on proven value propositions from original pitch.

My Contribution: Delivered comprehensive user journey mapping and feature prioritization framework that prepared the product for development phase.
