PAYVEMENT
I'm Dennis Vydrin — payments advisor and consultant with 10+ years across merchant acquiring, alternative payments and high-risk processing. I help merchants and PSPs enter new markets, cut processing costs, and build the teams and systems that keep payments running.
From strategy on a whiteboard to a service running in production.
Choosing the right acquirers, PSPs and payment methods for a market — and the sequence to launch them in. Geographic expansion research, competitor and pricing analysis, provider introductions and negotiation support. Tier-1 and developing markets.
Auditing your processing stack end to end: fees, routing, retries, cascading, decline reasons. I've led cost programmes that saved millions annually and lifted approval rates through structured product changes rather than guesswork.
Fraud and chargeback management systems that let high-risk businesses grow without crossing scheme thresholds. Monitoring, rules, dispute workflows, and the reporting to prove it's under control.
The product work that turns a payment decision into a shipped feature: functional and non-functional specifications, user stories with goals, analytics and wireframes, backlog prioritisation and grooming, product dashboards, test documentation and execution, bug reporting and fix validation.
When a spec doesn't need a full engineering team, I build it. Internal tools, microservices and integrations delivered end to end — specified, built, tested and handed over — using AI-assisted development (Claude Code, Codex) to go from idea to working service in days rather than sprints.
Hiring strategy, structure and ramp-up for payment teams. I built one from zero to 80+ specialists and ran it — so this is org design and interviewing, not a slide deck.
I founded Payvement in 2024 to do independently what I'd spent a decade doing inside companies: making payments work as a business function, not a technical afterthought.
For over ten years I've led payments and billing — heading payment operations, building billing infrastructure and, today, advising as a strategic partner. My background is concentrated in the industries where payments are hardest: online dating, forex and igaming, across both tier-1 markets and the developing markets of Asia, Africa and Latin America. That's where I learned that approval rates, risk exposure and provider mix are the same problem viewed from three angles.
