FinTech API Security & Financial Data Systems
Engineered for neobanks, payment processors, and wealth management platforms requiring zero-trust network architectures and bulletproof audit trails.
Production System Blueprint
Modular, horizontally scalable infrastructure engineered for resilience, high throughput, and zero single points of failure.
Frontend & Presentation
Hardened customer banking portal, security administrator audit console
Backend & API Services
Go / Python FastAPI microservices, Mutual TLS (mTLS), HSM hardware signing
Database & State Layer
PostgreSQL with row-level encryption, immutable event-sourced audit ledger
Cloud & DevOps Pipeline
AWS GovCloud / Dedicated VPC, HashiCorp Vault Enterprise, Datadog SIEM
Live Production Benchmarks
Every system built by MIHA Technologies is instrumented with rigorous automated latency, throughput, and reliability SLAs.
Optimized cryptographic verification and in-memory ledger pre-validation.
Hardware-accelerated TLS termination with pre-warmed session tickets.
SHA-256 hash-chained immutable ledger preventing retrospective record alteration.
Automated Strix penetration testing in pre-merge CI/CD pipeline.
Architectural Trade-Off Matrix
Deliberate technology selections evaluated on operational complexity, infrastructure cost, and developer velocity.
Guarantees cryptographic verification of both client and server identities, preventing lateral movement in the event of pod compromise.
Prevents catastrophic calculation drift and race conditions. Balances are derived by replaying cryptographically signed immutable journal entries.
Reduces PCI-DSS compliance scope from SAQ D to SAQ A-EP, cutting annual compliance audit costs by 85%.
Sprint Delivery Roadmap
Fixed-sprint engineering milestone cadence designed for full visibility and rapid production deployment.
Phase 1: Zero-Trust Network & PKI Setup
- Private Public Key Infrastructure (PKI) setup with automated certificate rotation
- mTLS service mesh configuration on isolated Kubernetes VPC
- Threat modeling and regulatory compliance gap assessment
Phase 2: Immutable Double-Entry Ledger
- Cryptographically verified double-entry accounting schema
- Transaction isolation with pessimistic locking on ledger accounts
- Plaid / Stripe tokenized bank account linking API
Phase 3: OAuth 2.1 & Biometric Key Signing
- Hardened authorization server with PKCE and short-lived JWTs
- Biometric step-up authentication for high-value fund transfers
- Real-time fraud scoring heuristic rules engine
Phase 4: Pentest, Audit Logging & Certification
- Full penetration testing with Strix addressing OWASP API Top 10
- SIEM real-time audit logging and suspicious activity alerting
- Compliance-ready executive architecture documentation and SOC2 audit pack
Security & Compliance Standards
Military-grade protection built into the application data flow from day one.
Frequently Asked Questions
Deep technical answers regarding integration, scale, and operational handover.
How do you protect financial APIs against Broken Object Level Authorization (BOLA/IDOR)?
We enforce strict entity ownership checks at the middleware and database layer using Row Level Security (RLS). Every database query joins on the cryptographically validated tenant and account context derived from the JWT, making horizontal authorization bypass mathematically impossible.
Does our infrastructure qualify for SOC2 and PCI-DSS compliance with this setup?
Yes. Our architecture is designed to satisfy SOC2 Type II Security, Availability, and Confidentiality trust criteria, as well as PCI-DSS Level 1 tokenization standards.
Can you integrate with core banking providers like Jack Henry, FIS, or Plaid?
Yes. We have deep integration experience orchestrating ACH transfers, wire approvals, and balance verification with Plaid, Stripe Treasury, and enterprise banking cores.
