Compliance Architecture Before the First Line of Code
PCI DSS scope, KYC/AML data flows, GDPR data residency, and audit trail requirements are defined during architecture — not discovered during a compliance review six months into development.

Why SolveJet
Financial systems are unforgiving. We build like they are.
A compliance gap in a payment system isn't a bug you patch in the next sprint — it's a regulatory incident. We treat fintech architecture as a risk management problem first, an engineering problem second.
Event-Driven Infrastructure for High-Frequency Transactions
Payment systems and fraud detection don't tolerate latency or data loss. We build on Kafka and GCP Pub/Sub with idempotency, distributed locking, and saga patterns to guarantee consistency at volume.
GCP-Native, Built for 99.99% Uptime
As a Google Cloud Partner, we architect with active-active redundancy, automated failover, and zero-downtime deployment pipelines — because a financial system going down isn't a UX problem, it's a regulatory one.
Direct Access to Engineers Who Understand Financial Risk
A bug in a payment ledger or a false positive in fraud scoring has real financial consequences. Our clients work directly with the engineers who built the system — not a support queue that escalates slowly.

Common Questions About Fintech Technology
Everything you need to know about building secure, compliant financial technology with SolveJet.
We build payment processing platforms, digital banking and neobank platforms, lending and credit platforms, wealth management and robo-advisory systems, fraud detection engines, KYC/AML compliance platforms, open banking APIs, and core banking modernization solutions.
We follow PCI DSS requirements throughout development — tokenizing card data, using point-to-point encryption, implementing strict access controls, and maintaining comprehensive audit logs. We work with PCI-certified infrastructure providers and can support your QSA assessment process.
Yes. We build KYC onboarding flows with identity verification (document scanning, liveness checks, database screening), AML transaction monitoring with rule-based and ML-powered detection, SAR filing automation, and regulatory reporting dashboards.
We architect payment systems using event-driven microservices, distributed databases, and message queues that handle millions of transactions per day. We implement idempotency, distributed locking, and saga patterns to ensure consistency at scale.
We build PSD2-compliant open banking platforms supporting OAuth 2.0, OpenID Connect, and Financial-grade API (FAPI) security profiles. We also integrate with financial data aggregators like Plaid, Yodlee, and TrueLayer for account data and payment initiation.
