How a payment is routed
Illustration: a payment goes from checkout to a routing engine, which skips a degraded gateway, sends it to the fastest healthy one, and it is approved.
Pay any way
Cards, Apple Pay, Google Pay and open banking, through one checkout.
Take the fastest healthy route
The routing engine checks every gateway, skips any that are degraded and picks the fastest.
Approve, and confirm
The acquirer authorises the payment and checkout shows it as paid, in milliseconds.
By the numbers
15+
payment gateways integrated
Global and regional gateways in a PCI DSS-compliant environment, chosen per transaction by one routing engine.
700+
payment channels orchestrated
Unified behind one API on the Paymid payment orchestration platform.
200+
currencies handled
Multi-currency processing across those channels, on the same platform.
What I build
I design, build and run regulated systems. Payment orchestration across 15+ gateways, with routing that fails over on its own. KYC, KYB and AML platforms that cut onboarding friction. Conversational AI that knows when to hand a customer to a person. From architecture to production support, end to end.

How it works
Three systems, step by step.
Onboarding, support and cross-border orders, automated end to end. The companies, orders and messages are examples; the flows are the real ones.
KYB and KYC onboarding
Built at Cellbunq: a business applies once, every check runs at the same time, and one risk score decides whether a person needs to look.
Illustration: a business submits its details and a director's ID, five checks run in parallel, and a risk score either approves it or sends it to a reviewer.
Apply once
Company details and a director's ID, in one short form.
Run every check at the same time
Registry, owners, sanctions, PEP and ID checks run in parallel across thousands of sources.
Decide on risk
Low risk is approved automatically. Anything else goes to a reviewer, with the reason.
Omni-channel AI chatbot
Built as iBot at SSL Wireless and the engine behind Chatshop: one bot for every messaging channel, with live handover to human agents.
Illustration: a customer message arrives, the bot identifies the intent and details, takes an action, and replies or hands the chat to a human agent.
Message on any channel
WhatsApp, Messenger, Telegram and web chat all reach the same bot.
Understand the request
NLP picks out what the customer wants and the details, such as an order number or a size.
Act, reply or hand over
It calls the same APIs as the support team, and passes the chat to a person when it should.
Cross-border procurement
Built at Woow Global as team lead: shoppers buy from Amazon, Alibaba, AliExpress and 1688, pay in their own currency, and the order is bought and shipped to their door.
Illustration: a shopper adds a product from an overseas marketplace, pays in their own currency through a local or international gateway, and the platform books the best-value carrier and tracks the parcel to their door.
Buy from any marketplace
A product from Amazon, Alibaba, AliExpress or 1688 is fetched and priced in the shopper's currency.
Pay in your own currency
Local and international gateways (SSLCommerz, Stripe, Authorize.net) take the payment in the shopper's currency.
Ship with the right carrier
DHL, FedEx, UPS and USPS are compared on price and time, and the parcel is tracked to the door.

Writing
Notes from production.
What is changing in payments, compliance and AI, and what it means for the systems behind them.
A tapped button answers the message it sits on, not the current one
Carry the prompt id and entity id in every button payload and reject a tap on a closed prompt, so a stale Yes never cancels the wrong order.
Give each outbound dependency a retry budget, not a retry count
A playbook for replacing per-request retry counts with a per-dependency retry budget, so a slow gateway gets a second try in a blip and no storm in an outage.
Lock the exchange rate at quote, at checkout or at charge
Pick when a cross-border order's exchange rate is fixed, size the margin to the gap before you buy the goods, and store the lock so every capture can prove it.
