About the project
My Real Profit is a SaaS analytics platform for Amazon sellers, giving FBA sellers, e-commerce brand managers, and inventory planners a real-time, accurate view of their margins after fees, returns, and ad spend. Most Amazon sellers know their revenue — very few know their actual profit; My Real Profit was built to close that gap. We led the web design and information architecture for the platform’s marketing site, interactive profit calculator pages, and a dynamic pricing system built to scale with seller growth. The brief was specific: build a minimalist visual system that makes dense, multi-layered e-commerce data feel immediately actionable.
Digital illustration and animation for mobile interactions
Here are the critical gaps we found: Amazon Seller Central hands sellers raw data — it doesn’t tell them what it means.
- Sellers mispricing products and misreading growth — no clear per-unit profitability picture without manual spreadsheet reconciliation.
- Dashboard fatigue — cluttered interfaces had trained sellers to distrust third-party analytics tools before exploring the feature set.
The platform needed to earn confidence fast — within a single scroll — or lose the visitor entirely.
Our solution
High-clarity hero with social proof and an immediate UI preview (1,000+ sellers) — gives visitors a concrete sense of ‘real-time profit truth’ before reading a word of copy.
Dedicated per-unit profit calculator lets sellers adjust their own metrics and watch margin impacts update live, turning an abstract value proposition into a tangible proof point.
Feature sections organised by business function — Finances, Operations, Sales — so teams self-identify their use case without wading through irrelevant tooling.
Three-tier pricing with a built-in calculator pairs flat fees with a percentage-of-revenue structure, scaling cleanly from solo sellers to multi-brand agencies.

About the project
CurrencySavvy is a professional-grade cryptocurrency trading and portfolio management web app. Most crypto platforms make a choice: power user or beginner — CurrencySavvy was designed to serve both without compromising either. We led the end-to-end product design, covering everything from the integrated trading terminal to the technical analysis suite and portfolio management modules, plus the full dark-themed UI system, interactive charting components, asset allocation visualizations, and the navigation architecture that ties it together. The design standard was a platform that active traders could rely on under pressure and portfolio investors could read at a glance — without sacrificing depth for simplicity.
What problems we found
Here are the critical gaps we found: crypto trading UX tends to fail in one of two directions — stripped-down interfaces that lack the data serious traders need, or engineer-built terminals so dense they become error-prone under the pressure of live markets.
Poor contrast ratios and cluttered layouts — costly, not just aesthetic, for users staring at charts for hours.
- Real-time market data and personal performance metrics lived in separate places, making it hard to connect market moves to holdings.
- Critical tools like wallet management and trade history hidden behind multiple navigation layers instead of one click away.
The platform needed to earn confidence fast — within a single scroll — or lose the visitor entirely.
Result
Integrated trading terminal puts portfolio summary, real-time earnings graphs, and trade history on one screen — eliminating the tab-switching that fragments decisions during active trading.
Statistics view delivers high-fidelity candlestick charts alongside 24-hour high/low metrics and volume indicators, without interface clutter.
Color-coded asset allocation cards show token weight across BTC, ETH, DOGE, and others at a glance.
Persistent sidebar keeps Wallet, Transactions, and Token Market one click away, with glassmorphism and consistent red/green indicators reducing cognitive load across long sessions.

About the project
Quoroom is a private market investment platform that gives individual and institutional investors access to curated deals, from first browse to final signature. Private market investing has always demanded desktop time, document printers, and patience — Quoroom was built to make that expectation obsolete. We designed the end-to-end mobile experience covering the full investment lifecycle: deal discovery, KYC verification, document signing, payment execution, and portfolio management across multiple legal entities. The design standard was ambitious — the simplicity of a consumer banking app, without compromising the legal rigor private equity demands.
Result
We designed four core flows that collapse a traditionally desktop, paper-heavy process into a mobile-first experience:
investment discovery feed organised by status (All, Committed, Pending) with real-time funding progress bars for an instant read on deal momentum;
guided KYC wizard handles identity verification and ID uploads in a secure, step-by-step flow — removing the back-and-forth that typically stalls onboarding;
integrated Sign and Commit to Invest collapses a multi-day manual process into a few taps, cutting time-to-commit from days to minutes;
centralised entity and portfolio hub gives investors the same ownership visibility across companies and legal structures a desktop dashboard would — in their pocket.

FAQ
-
A UX audit is a structured analysis of a digital product that identifies usability issues, conversion barriers, and user experience gaps. It combines UX heuristics, analytics data, and user behavior insights to provide clear recommendations for improving usability and increasing product performance.
-
A UX audit identifies friction points in the user journey, such as confusing navigation, unclear messaging, or poor interaction design. Fixing these issues helps users complete key actions faster, which can significantly increase conversion rates and reduce drop-offs.
-
A SaaS product often needs a redesign when user engagement drops, conversion rates stagnate, or the interface becomes difficult to scale. A redesign improves usability, modernizes the interface, and aligns the product experience with current user expectations.
-
Most UX audits take between one and three weeks depending on product complexity. The process usually includes UX analysis, analytics review, competitor research, and a structured report with prioritized improvement recommendations.
-
UX research helps teams understand real user needs, motivations, and pain points. Instead of relying on assumptions, companies can make informed design decisions that improve usability, increase engagement, and build products that users actually want to use.
-
Absolutely—we design both web and mobile interfaces. While we don’t take on landing pages as standalone projects, we include them as an integral part of the overall product experience when we’re designing your digital product.
-
Yes, we offer flexible engagement options depending on the scope and needs of your product. Companies can work with us on a project basis, part-time collaboration, or ongoing design support. This flexibility allows teams to access senior UX and product design expertise without committing to a full-time in-house hire.
