We sat down with Andrii Bruiaka, a technology leader with more than 15 years of experience across fintech, payments, and digital infrastructure. Today, he and his team are focused on the launch of Onicore.io — a platform designed to help businesses better understand, manage, and scale the systems they rely on.
With a background spanning neobanks, payment orchestration, and cross-border financial systems, Bruiaka positions Onicore.io as a response to a growing structural shift in fintech: increasing dependence on fragmented “borrowed infrastructure” that most companies don’t fully control or even see.
Below is the full conversation, structured around the core tensions shaping modern financial systems.
You’ve worked across neobanks, payment orchestration, and cross-border systems. What part of modern fintech infrastructure is still most misunderstood from the outside?
From the outside, people look at fintech and see beautiful UIs, instant apps, and seamless transitions. They think innovation is in the frontend. The reality is that the front is just a tiny layer. The most misunderstood part is the sheer, brutal complexity of the backend “plumbing” — specifically, the interaction between legacy core banking systems and modern API layers.
People don’t realize that when they press “send,” that transaction might trigger a chain of five different intermediaries, compliance checks, AML screenings, and ledger updates — all within milliseconds. Modern fintech isn’t about creating new money; it’s about mastering the physics of moving it safely through old pipes.
Where do fintech narratives most often diverge from how systems actually work at scale?
The biggest narrative myth is the “one-click global expansion.” Marketing copy makes it sound like you can integrate one SDK and suddenly accept payments in 150 countries.
At scale, that narrative collapses. It ignores regional fragmentation, local banking cartels, fluctuating currency corridors, and sudden regulatory shifts. When you process millions of dollars, you realize there is no such thing as a truly “global” system; there is only a massive network of heavily localized realities stitched together. Scale forces you to stop looking at fintech as a smooth digital highway and start treating it like a complex, unpredictable terrain.
At what point does a fintech company stop being an infrastructure builder and become an orchestrator of external systems?
You stop being a builder and become an orchestrator the moment you realize that rewriting the entire financial system from scratch is an inefficient ego trip. Building your own rails in every country is too slow and capital-intensive.
You become an orchestrator when your core value shifts from owning the pipes to controlling the traffic inside them. It’s the transition from being a construction company to an air traffic controller. Your intellectual property is no longer the code that holds the data, but the intelligence that routes it.
Who ultimately has more control over financial infrastructure today: fintech companies or the providers they depend on?
Right now, providers — the Tier-1 clearing banks and massive legacy processing networks — still hold the ultimate leverage. Fintechs like to think they are disrupting the world, but if a partner bank changes its risk appetite or shuts down an account, a fintech can vanish overnight.
However, the balance of power is shifting. Companies that understand orchestration are reducing this dependency. By building multi-provider setups, you don’t depend on a single link. True control today belongs not to the one who owns the infrastructure, but to the one who can plug into ten different systems simultaneously and switch between them in a heartbeat.
What category is Onicore actually trying to define in the infrastructure space?
We are defining the category of Adaptive Transaction Intelligence. We don’t want to be just another “payment gateway” or a static orchestration tool. We are building the dynamic layer that sits above the chaos of global payments.
Onicore is designed to be a system that doesn’t just pass data along, but actually understands the context, health, and risk of every payment corridor in real time. We are creating a space where infrastructure isn’t passive; it’s a living shield that protects a business’s conversion and compliance.
What is the biggest misconception people have when they first hear about Onicore?
People hear “payment platform” and immediately assume we are trying to compete with Stripe or Adyen. That’s the biggest misconception. We aren’t a merchant acquirer; we don’t want to replace your existing processors.
We are the layer above them. We don’t replace the pieces of your payment puzzle; we are the frame that holds them together and makes them work efficiently. We aren’t another player on the field; we are the coach optimizing the team.
What is the hardest part of building a company like Onicore: the technology itself or the market understanding of the problem?
The market understanding, without a doubt. Writing secure, high-throughput code is a solved engineering problem if you have a great team. But explaining to a CEO or VC why their current payment setup is losing them 15% in hidden failures and inefficient routing is the real challenge.
Payments are often treated like utility bills — something you just pay and ignore. Getting the market to understand that payment infrastructure is a core strategic asset, not just a line-item expense, requires a massive shift in perspective.
How is AI changing financial infrastructure beyond automation — especially in terms of visibility and decision-making?
Beyond simple automation, AI is giving us eyes into the dark corners of financial networks. Historically, when a payment failed, you got a generic error code like “Decline.” It was a black box.
AI changes this by bringing predictive visibility. It looks at patterns across millions of transactions and can tell you: “This specific corridor is failing because a regional bank in Brazil is experiencing latency right now.” It moves us from reactive troubleshooting to proactive decision-making. AI allows the system to see a bottleneck forming and route around it before the failure even happens.
Does AI make infrastructure more understandable to operators, or does it add another layer of opacity?
It’s a double-edged sword, but if implemented with plain integrity, it makes things more understandable. If you use AI blindly as a “black box” that makes decisions without explanation, it adds dangerous opacity.
In fintech, you can’t just say “the algorithm decided to block this million-dollar transaction.” You need an audit trail. At Onicore, we believe AI should act like an expert co-pilot — it shouldn’t just change the route; it must clearly explain the data points behind that decision so human operators retain full context and control.
Has crypto actually changed the architecture of cross-border payments, or mainly shifted how the system is perceived externally?
Architecturally, stablecoins and smart contracts have fundamentally proven that settlement doesn’t need to take three days or rely on the SWIFT network. It proved that peer-to-peer liquidity works at scale.
However, on a macro level, it has mostly shifted perception. It forced traditional banks to realize that their inefficiency is no longer a given — it’s a choice. The real architectural revolution isn’t crypto replacing fiat; it’s traditional infrastructure adopting the speed and cryptographic verification principles of blockchain to save itself from obsolescence.
In infrastructure-heavy industries like fintech, how much does perception influence what gets built versus actual technical need?
Perception and hype influence far too much of what gets built, especially during bull markets. Founders often build complex features just because it sounds good in a pitch deck — whether it’s “AI-everything” or blockchain-based solutions for problems that a simple SQL database could solve. This creates massive technical debt.
I’ve always believed in plain integrity. You build for the actual, unglamorous technical need of the client, not for market applause. A boring, robust system that consistently achieves 99.99% uptime and saves a merchant millions in conversion fees will always outlast a hyped-up, fragile feature built just to follow a trend.
Conclusion
What emerges from this conversation is less a story about fintech tools and more a shift in how infrastructure itself is understood. The industry is moving from ownership to orchestration, from static systems to adaptive intelligence layers, and from blind dependency to distributed control.
In that transition, companies like Onicore.io are not just building infrastructure — they are redefining what it means to see infrastructure at all.
