Frontend Engineer · Product Builder. Five years architecting enterprise FinTech.

Available immediately · Brighton, open across the UKRight to work in the UK

Based in Brighton, available immediately for senior and lead frontend roles across the UK. Five years across enterprise FinTech — trading platforms, finance automation, and decision-intelligence systems — with deep experience in design systems, accessibility (WCAG 2.1/2.2), and shipping to regulated environments. Equally happy embedded in a product team or leading frontend architecture. Open to product collaborations on the side.

01 / ProductsLive products.

Two products built independently — both live, both running, both happy to demo. The screens here give you the shape. The depth is a 20-minute conversation away.

Readyjourneylint

JourneyLint

Evaluate flows, not isolated screens.

A systematic linting engine for UX and frontend systems. JourneyLint analyses real user journeys end-to-end across UX, accessibility, performance, and architecture — surfacing the systemic patterns that page-level tools like Lighthouse and axe were never built to see. Built for teams who care less about scores and more about whether the journey actually works.

KiteSignal

AI-generated swing trade signals for the NSE.

An AI-powered signal platform built for the Indian stock market. KiteSignal screens the NSE universe through institutional methodology — trend templates, relative strength, pocket pivots — and runs surviving candidates through a multi-stage reasoning chain before any signal reaches the user. Every alert ships with full audit trail: scores, risks, invalidation conditions, and the reasoning behind the call.

03 / DesignProblems I lived. Then redesigned.

Three apps I use every week — Airbnb, LinkedIn, Deliveroo. I hit a wall in each one as a real user, then put on the designer hat and worked through how I'd fix it. Two are complete write-ups; one is in progress. Read the full studies on the design page.

Airbnb — Long-Term Stays & Extended Accommodation

Mobile App Redesign · 3-week design sprint

I tried to book a 4-month stay on Airbnb for my UK move. It went badly. Here's the redesign that came out of that frustration.

LinkedIn — Job Application Tracker

Web + Mobile Feature Design · 3-week research sprint

I was applying for UK roles on LinkedIn and realized every application disappears the moment you click Apply. So I redesigned the part LinkedIn forgot to build — and talked to eight other job seekers who had hit the same wall.

Deliveroo — Reducing Friction in Food & Grocery Ordering

Mobile App · Ongoing UX research

I order from Deliveroo more often than I'd admit. The homepage forgets I have a history. This case study reworks the order flow around the user the app already knows.
