I build products at the intersection of AI, payments and commerce. I've sat on both sides of the table: as an enterprise buyer of payment solutions, and as a fintech SaaS vendor building and selling them to ecommerce, travel and iGaming companies.
Previously I led global payments product at Entain (FTSE 100), with a portfolio of products processing $40B+ in annual transaction volume, and global platforms at Signifyd (Series E fintech in fraud prevention), managing a portfolio worth 24% of the company's ARR. Before that, at ASOS (FTSE 250), I worked on digital transformation across payments, order management and supply chain. I have a computer science background and an MBA.
Outside of work, I also:
- Build AI products as side projects, starting with problems I face myself. Some now have real users: Nura (a family AI assistant) is in private beta with 10+ users, and TabSearch (a Chrome extension for managing tabs) has 400+ installs. I open source what might help others. See the projects.
- Share what I learn on LinkedIn, X and Substack.
- Practise public speaking as an active Toastmasters member.

ganeshi.substack.com ↗Experience · where I've worked the problem
15+ years across commerce, fintech and regulated payments. This is the path a payment takes, and where I've worked on it.
- 01 · SHOPSupply chain
At Harvey Nichols, led logistics platform strategy for £50M+ of ecommerce revenue, cutting delivery costs by 24% (£3M+) with multi-carrier routing.
- 02 · ORDEROrder management
At ASOS, built APIs across payments, order management, fulfilment and ERP, and led the microservices move behind 60% year-on-year growth in Black Friday peak traffic.
- 03 · PROTECTFraud and payment risk
Launched a 0-to-1 SCA exemption product for EMEA merchants: low-risk payments go frictionless, high-risk ones go to 3DS. It scaled from zero to $5B+ GMV.
- 04 · APIAPI products
Architected REST APIs handling 5M+ decisions a day at p99 under 700ms, and rebuilt the docs and tooling to cut enterprise onboarding time by 25%.
- 05 · PLATFORMEcommerce platform integrations
Expanded integrations with Shopify, Magento, VTEX, SAP and Salesforce across Europe and LATAM, adding $6M+ in new bookings.
- 06 · PAYAuth, routing, local payment methods
Intelligent routing across 20+ PSPs added £10M+ a year in revenue, and a Pix integration lifted Brazil new-user conversion from 55% to 85%.
- 07 · MOVE MONEYDeposits, withdrawals
Cut withdrawals from 3 days to under 5 minutes for 92% of £500M+ a month in payouts, using real-time rails, and lifted payment NPS from 72 to 91.
- 08 · COMPLYUKGC, US gaming boards
Delivered compliant payment flows for the UK, Brazil, US states and the EU, including automated Source of Funds and affordability checks via Open Banking.
At Entain I led the evaluation of 9 payment orchestrators and 3 network tokenisation providers for a $40B+ payments stack, and took a top-3 shortlist to the C-suite.
At Signifyd I led onboarding and activation for our global platforms, used by SMB to mid-market merchants ($40M ARR), and launched a 0-to-1 SCA exemption product for EMEA merchants. Today I'm building payment orchestration and acquiring solutions for iGaming and white-label platforms.
Largest scale: $40B+ a year in payment volume, 20+ PSPs in 20+ regulated markets, regulators from the UKGC to US state gaming boards.
Now: taking this into AI, starting with evals on real products. See the projects.
About
I'm a product builder at heart, and with AI a full-stack one: I can take an idea through the business case, spec, build, test, launch and measurement myself. I build side projects to solve problems in my own life and open source what might help others. Doing the work, not just reading about it, keeps what I learn honest.
I've lived in India, the UK and Dubai, and worked with teams across Latin America, the US, Europe, the Middle East and India. A computer science background and an MBA mean I'm at home in the technical weeds and in C-suite conversations about strategy.
Outside work: two daughters, football (Man Utd and Barça) and Toastmasters.
Open to advisory conversations with payment teams, vendors and merchants taking AI from demo to something they can trust. Email me.
