Fintech Software Development
Secure, auditable financial software
DanixSoft builds fintech software — payment integrations, financial dashboards, onboarding, and lending workflows — with encryption, audit trails, and least-privilege access designed in from the start.
Financial software lives or dies on correctness and trust. We build payment integrations, dashboards, onboarding, and lending workflows with encryption, audit trails, and least-privilege access designed in from the start.
What do we build for fintech?
Purpose-built technology to solve your specific industry challenges.
Payment Processing
Stripe, PayPal, and custom gateway integrations with PCI-DSS compliance.
WealthTech & Trading
Real-time WebSocket data feeds, charting, and secure ledger systems.
Fraud & Anomaly Detection
Rules and machine-learning models that flag unusual transactions for review.
Digital Banking
Onboarding, KYC, account management, and transaction interfaces built for scale.
Lending Platforms
Application scoring, decisioning workflows, and servicing dashboards.
Regulatory Reporting
Auditable data pipelines that turn transaction history into the reports regulators ask for.
How do we deliver?
A milestone-driven process built around your regulatory reality.
Risk & Requirements
We start with the threat model and the regulatory perimeter, because both dictate architecture in financial software.
Secure Architecture
Segregated environments, least-privilege access, encrypted data stores, and immutable audit trails designed in from the first sprint.
Iterative Build
Two-week increments with continuous integration, automated testing, and peer-reviewed code throughout.
Security Testing
OWASP-based security review, dependency auditing, and load testing against realistic transaction volumes before launch. Independent penetration testing can be arranged with your chosen provider.
Launch & Monitor
Staged rollout with real-time monitoring, alerting, and incident response procedures in place from day one.
Technology Stack
The tools we rely on to build for this sector.
Which standards do we design for?
Requirements we design for in this sector. These are not certification claims; we build so that your own compliance and audit work is easier.
PCI-DSS
Cardholder data handling, network segmentation, and scope-reduction strategies such as tokenisation.
KYC / AML
Identity verification and transaction monitoring workflows integrated with your chosen providers.
SOC 2 readiness
Logging, change management, and access review practices that support a SOC 2 audit.
GDPR
Data minimisation, retention policy, and subject rights handling for EU customers.
Frequently Asked Questions
Common questions about building software for this sector.
How do you secure financial data?
Encryption in transit and at rest, strict environment segregation, least-privilege access, immutable audit logging, and dependency scanning in CI. For card data we prefer tokenisation so sensitive values never touch your servers, which also reduces PCI-DSS scope.
Which payment providers do you integrate?
Stripe, PayPal, and regional gateways via their APIs. Where no suitable provider exists, we can build middleware against the acquirer or bank API directly.
Can you handle high transaction volumes?
Yes. We design for horizontal scaling with queue-backed processing and load test against realistic peaks before launch rather than discovering limits in production.
Do you build crypto and blockchain platforms?
We can build wallets, exchange interfaces, and ledger systems, and we are candid about where a blockchain genuinely helps and where a conventional database is the better engineering choice.
Who owns the code?
You do. Full source, infrastructure definitions, and documentation transfer to you on delivery.
