New Dealigence

Dotbig — a proprietarytrading platform

A multi-asset trading platform — forex, stocks, crypto and commodities in one terminal. Web, mobile and an internal CRM.

Project overview

Background

Renting, not owning.

NewDealigence is a venture lab that builds and operates its own products. For their trading operation they had been renting a third-party platform — paying recurring fees for software they couldn't shape.

Challenge

Make complex trading feel simple.

Live markets, orders, risk and compliance — without overwhelming a first-time trader. And ship it fast enough to go live, not perfect-on-paper.

Outcome

Shipped, licensed, still running.

Three products in ~12 months — web, mobile and an internal CRM — replacing the rented stack and earning an operating license.

Role

Lead Product Designer
End-to-end product design

Timeline

~12 months to live v1

Scope

Web · Mobile · CRM

Markets

Worldwide

Markets

Multi-asset

Forex, stocks, crypto, commodities — filterable by country.

Buy / Sell, SL & TP

Order panel

Risk controls with live validation — potential loss/profit as you type. Proposed & shipped.

KYC / AML

Regulated onboarding

Step-by-step identity verification with clear document guidance. Built licensing-ready from day one.

Deposits & withdrawals

Wallet

Transparent money flow with full history and clear statuses. Proposed & shipped.

Referral program

A multi-level referral dashboard with live earnings.

Agent calls

In-app chat

Built-in support chat and live agent calls inside the platform — a rarity in trading products. Proposed & shipped.

THE DIFFERENTIATOR

Regulated UX, designed in from day one.

KYC/AML, identity verification and compliance flows aren't bolted on at the end — they're part of the core experience. It's what let the product earn its operating license without compromising on usability.

web Mobile

Trade, set risk and confirm on the go — the desktop power, reworked for a small screen.

Dotbig mobile trading screen

The platform replaced the rented product entirely, went live, and earned its operating license — the bar that decides whether a trading product is allowed to exist at all. Years on, the relationship continues: I still support the product as new requirements land.

Crypto Platform (NDA)

An advanced trading terminal —led end to end.

A multi-asset CFD & forex terminal — charts, order execution, social trading, reports and MT4. Led the design end to end, under NDA.

Project overview

Background

Joined as the lead.

A large, multi-module trading product under NDA. I came in as design lead, owning the experience across the whole platform — not a single screen.

Challenge

Order in a dense cockpit.

Charts, orders, positions, signals and social — all live at once. The job was one consistent system across every module and breakpoint.

Outcome

One system, many modules.

Terminal, reports, social trading and MT4 — unified into a single responsive system across desktop, tablet and 1920.

Social trading

A multi-asset CFD & forex terminal — charts, order execution, social trading, reports and MT4. Led the design end to end, under NDA.

Social trading — copy traders

Reports & analytics

Trading history turned readable — P/L, win-rate, most-traded assets and account summaries.

Reports and analytics dashboard

Price alerts

Every alert in one place — set thresholds by asset and rate, track distance to target, manage them all from one table.

Settings

Modular

One settings system that adapts to what's enabled — with or without signals and social.

Modular settings

THE DIFFERENTIATOR

One system, every screen size.

The full terminal re-flowed for tablet (1024) and 1920 — keeping cockpit density, never dumbing it down. Risk-tolerance controls and edge states designed in, not bolted on.

MT4 integration

Bridge to the industry standard — MT4 living inside the same product shell.

MT4 integration

Designing trading platforms means making dense, regulated systems feel effortless. On this CFD and forex terminal I led the product design end to end — from the live trading cockpit and order execution to social trading, reports and MT4. If you're a fintech or trading founder looking for a senior product designer who understands order flow, risk and KYC — not just screens — this is the kind of work I do.

THE BACK OFFICE BEHINDTHE TRADING PLATFORM.

A multi-asset CFD & forex terminal — charts, order execution, social trading, reports and MT4. Led the design end to end, under NDA.

Project overview

Background

Rented didn't fit. Built our own.

They rented a CRM but it couldn't do what the business needed. So we built our own admin platform from a blank canvas.

Challenge

A whole business in one back office.

Leads, deposits, withdrawals, roles, reports — dense operational data that had to stay fast and clear for sales teams.

Outcome

Used in-house, rented by brokers.

A multi-brand admin that runs the business — and successful enough that other brokers rented it with their platform.

Dashboard

One dashboard, every brand — registrations, deposits, withdrawals and net, filtered by brand and date.

Multi-brand CRM dashboard

Lead card

The sales cockpit — contact, KYC, finances, trading accounts and team comments in one dense view.

CRM lead card

Finance reports & presets

Thousands of transactions, saved filter presets, custom columns and export — big data made workable.

CRM finance reports and presets

Roles & permissions

Granular role-based access — edit/view per object, departments and API scopes for teams and tenants.
Sale statuses, user groups and notification rules — configurable per brand and team.

CRM roles and permissions

THE DIFFERENTIATOR

One CRM, many brokers.

Multi-brand and white-label from the core — the same admin runs several brokerages, each on its own brand. Rented out as a product, not just used in-house.

A mobile-first trading app — live charts, orders, positions, wallet and reports as a PWA and iOS. Led the design with a team, joined to solve problems and steer the product.

Project overview

Background

Joined to steady a moving product.

I came in as design lead when the product hit problems. Each designer owned their part — I held the system and solved the cross-cutting issues.

Challenge

A whole terminal, on a phone.

Charts, orders, risk, positions and reports — the full trading experience, made to work one-handed on a small screen.

Outcome

Shipped as PWA and iOS.

A complete mobile trading app — two modes, full order flow, reports and wallet — released across web and iOS.

WHY WORK WITH ME

I turn complex, regulated systems into clear digital products people can trust. Fintech and trading are my core expertise — alongside other complex platforms built from concept to production.

You work directly with me

No account managers. No junior hand-offs. Async-first, so we don’t need endless meetings — you always know what’s moving.

Discovery

I start with your business and constraints — users, regulation, competitors. Before Figma, I define what a win looks like and what can’t break.

Design

Flows first, then high-fidelity UI on real data. You get clickable Figma prototypes early — no surprises at the end.

Ship

Clean Figma, design tokens, dev-ready handoff and close work with your engineers. I stay through build with async updates and Loom walkthroughs.

Iterate

After launch, I help measure and refine — onboarding, conversion and the rough edges that only appear with real users.

WHAT I COVERWhere I go deep

Trading & terminals

Real-time charts, order flows and execution UIs traders trust under pressure.

Crypto & exchanges

Spot, wallets, on/off-ramp and KYC flows for CEX and Web3 products.

Neobanking & payments

Accounts, cards, transfers — clear flows for moving money.

Design systems

Scalable, themeable systems across web, mobile and CRM.

Regulated UX

KYC/AML, disclosures and audit trails built in from day one. Licensing-ready, not bolted on.

WHY WORK WITH ME

I turn complex, regulated systems into clear digital products people can trust. Fintech and trading are my core expertise — alongside other complex platforms built from concept to production.

TradingCryptoNeobankingInvestingDesign Systems
Complexity → clarityI translate dense product logic into simple decisions, clear hierarchy and predictable interaction.
Fintech & cryptoTrading platforms, exchanges, wallets, KYC, deposits, dashboards, CRM and admin tools.
Product partnerI think beyond screens: user goals, business model, edge cases, risk, data and delivery constraints.
Lean executionFast structure first, then visual polish. I avoid decoration until the product logic is strong.
System thinkingReusable components, states, spacing, typography, tables, cards, filters and responsive rules.
Senior outputDirect communication, practical handoff, QA mindset and design that can actually ship.

Design philosophy

Great product design is not only about how something looks. It should reduce noise, create headspace and make the next decision obvious. In fintech, that matters even more because users deal with money, risk, trust and time-sensitive actions.

How I think

Before polishing UI, I map how the product works: who uses it, what they need to do, where they can get confused, and which decisions create business value.

Why fintech

Financial products are often overloaded with information. My goal is to make them feel controlled: clear states, understandable actions, visible feedback and strong hierarchy.

Toolbox

Figma, FigJam, Miro, Notion, Loom, analytics, user testing, AI tools and structured async communication.

What I believe

Good design should create less noise and more headspace. In financial products, every screen should help the user understand what is happening, what changed, what matters now and what action is safe to take next.

How I work

I start with the product model before moving pixels: who uses it, what they need, where they hesitate, what can go wrong and which decisions create business value. Then I build flows and UI systems around that logic.

Why fintech

Fintech products are not only interfaces — they are trust systems. The design has to communicate control, reliability, risk, status, feedback and confidence without overwhelming the user.

What I bring

A mix of UX architecture, visual direction, design systems and product thinking. I can move from blank canvas to structured MVP, from messy dashboard to clean operating tool, or from existing UI to a sharper product experience.

Toolbox

Figma, FigJam, Miro, Notion, Loom, analytics, user testing, AI-assisted exploration and structured async workflow. Tools change; the important part is clear thinking and fast, useful output.
