10+ years in FinTech, Banking, and Web3 design experience, leading design transformation from 0→1 launches to multi-squad organizations. I combine Jobs-to-be-Done thinking, progressive-disclosure UX, and bold visual craft to translate complex financial systems into intuitive, human-centred experiences.

Saman banking app redesigns have driven a 40% uplift in user engagement and a 30% reduction in feature development time.

Professional Experience

wallet.comProduct Design Director

Mar 2024 – Present | Full-time, Remote

Defined product vision, design strategy, and growth roadmap for a self-custodial crypto wallet from day one.

  • Led 0→1 product launch end-to-end: applied a Jobs-to-be-Done framework to surface users' core hiring criteria, then used an Opportunity Solution Tree to ruthlessly prioritize features for the MVP — shipping on schedule with a Day-30 retention rate of 41%, exceeding the 35% target set for the initial release.


  • Designed a first-of-its-kind multi-network token-merge system using progressive-disclosure principles; A/B tested two information architectures and shipped the variant that reduced task- completion errors by 34%.


  • Redefined crypto lending UX from scratch, applying HIG and Material Design 3 guidelines to ensure gesture coherence on iOS and Android; usability testing showed a 28% drop in support tickets related to borrowing flows.


  • Integrated AI capabilities across the wallet using a context-aware decision layer; validated via tests that AI-assisted swap suggestions increased swap conversion rate by 22% vs. control.


  • Built a seedless passkey-auth onboarding flow; the cinematic, step-by-step narrative UI cut new- user drop-off by 19%.

blu BankProduct Design Leader

Jan 2023 - Mar 2024 | Full-time, In-house

Led design across 20-person team serving six business lines (Blu Junior, Blu Personal, Blu Business, + three new ventures).

  • Architected a unified, token-based design system (inspired by Material Design 3 and tailored to HIG for the iOS-first banking app) that reduced design-to-dev handoff time by 30% and enforced visual consistency across six product lines.


  • Applied the Kano Model and OKR-aligned design planning to prioritize the Blu Business MVP feature set; the launch achieved an NPS of +52 and a 62% Week-2 activation rate, both surpassing pre-launch benchmarks within the first month.


  • Ran a series of customer-centric discovery sprints (including empathy mapping, contextual inquiry, and Jobs-to-be-Done interviews) to define the Blu Tourism super-app proposition, surfacing three unmet needs that shaped the roadmap.


  • Designed efficiently under constraints: reused 80% of existing components, created a bold, geometric icon system in-house to replace third-party illustration spend, and delivered Blu Junior end-to-end in 6 weeks without compromising visual quality or UX coherence.


  • Initiated and architected a unified, scalable design system serving multiple business models—accelerating product development and improving UI/UX consistency.  


  • Designed the organizational design ladder for the 20-person team, defining roles, career paths, and leadership progression across core and distributed squads.


  • Modeled and implemented team feedback and emotional health processes, improving internal team dynamics and individual growth across all design roles. 


  • Developed a strategic communication structure between the design team and cross-functional departments (product, tech, ops, C-level), increasing alignment and design visibility.  


  • Planned to launch a high-performing MVP for Blu Business, Blu Tourism & Blu supper app with strong user satisfaction and positive early engagement metrics.

Saman BankProduct Design Leader

Feb 2021 - Jan 2023 | Full-time, In-house

Lead product designer for four banking products simultaneously, balancing speed, quality, and team growth.

  • Structured and scaled the design team from the ground up; introduced the Un-Fix squad model and Design Ops rituals (weekly design reviews, async feedback loops..).


  • Redesigned the Personal Financial Management dashboard; the winning variant drove a 40% increase in feature engagement.


  • Designed Split Bills and Contact Transfer using a customer-centric story-mapping process (user personas + JTBD + emotional journey maps), resulting in a 20% increase in monthly active users.


  • Revitalized the Gift Card feature with a visually bold, motion-forward redesign; cinematic onboarding animation tested via preference testing outperformed the static control by 3:1 and lifted registrations by 5%.


  • Scaled the design function from 2 to 8 designers using the Un-Fix model; introduced design crits, friction logs, and knowledge-sharing rituals that cut design rework by 25%.


  • Implemented HIG-compliant accessibility patterns (color contrast, dynamic type, touch targets) across all four products, reducing accessibility-related bug reports by 40%.


  • Developed a design team roadmap ladder and role positioning framework from the ground up to structure and clarify responsibilities across a growing product landscape.  


  • Scaled the design function to support emerging business lines with a lean team setup, balancing quality and speed of delivery.  


  • Established feedback and knowledge-sharing practices within the design team and across departments, fostering a culture of learning and continuous improvement.
