NeoBank Engineering Masterclass
A production-grade bank,
built module by module.
This is a 24-module, project-based curriculum for engineers who want to ship a real banking app on Expo and React Native — not a demo. You'll build NeoBank from the ground up: encrypted state, biometric auth, a server-side BFF that keeps every credential off the client, and the same security and monitoring decisions used by production fintech teams.
Bank-grade security
Biometric login, encrypted-at-rest state, secure vaults, and App Attest / Play Integrity checks on every request.
BFF architecture
A server tier that signs requests, rate-limits, audit-logs, and holds every bank credential — the client never sees a secret.
Real money movement
Intra-bank, inter-bank, mobile money, and cross-border transfers — with limit checks, idempotency, and receipts.
Ship-ready workflow
Snyk, Sentry, CI/CD with EAS, feature flags, and a 24-module hardening checklist before going live.
Built for engineers who are ready for the real thing.
You already know TypeScript, React, and the basics of mobile development. This course is for what comes next — regulated apps, real money, and the security decisions that come with both.
You can build apps. Not systems.
You are comfortable with React and TypeScript, but every production codebase you encounter has layers — security, state encryption, session management, BFF patterns — that no tutorial ever covered.
- You have never touched biometric auth, encrypted state, or secure storage in a real app.
- You don't know how to keep API credentials off the client in a mobile app.
- Your portfolio has nothing that signals you can work in a regulated, money-moving environment.
You are ready to go deeper.
Whether you are a tech lead evaluating architecture for a wallet or neobank, or a security-curious engineer who wants hands-on experience with mobile threat modelling — this is where you get it.
- Implement App Attest, Play Integrity, OWASP MASVS, and real session lifecycle management.
- Design a BFF that signs requests, enforces rate limits, and writes audit logs — never exposing bank credentials to the client.
- Graduate with a public monorepo, a threat-model doc, and a video walkthrough — a portfolio piece that speaks for itself.
NeoBank — a complete, production-ready banking app
Not a clone, not a demo. A multi-platform iOS and Android consumer banking app you would actually ship — with every security, monitoring, and integration decision made deliberately.
Biometric login + transaction signing
Face ID / Touch ID via expo-local-authentication, a PBKDF2 fallback passcode, session lifecycle with inactivity timers, force-close detection, and per-transaction biometric re-auth.
Field-level encryption on every secret
Legend-State v3 + MMKV with a custom persistence plugin. Auth tokens and PINs encrypted at HIGH, account data at MEDIUM, UI prefs in plaintext — transparent to feature code.
Bank credentials never touch the client
Expo Router API Routes on EAS Hosting proxy every upstream call — JWT validation, HMAC-SHA-512 request signing, rate limiting, and audit logs all server-side.
Intra-bank, inter-bank, mobile money & cross-border
Name enquiry, limit checks, idempotency keys, optimistic UI with rollback, scheduled transfers, and PDF receipts via expo-print.
App Attest + Play Integrity on every request
Hardware-bound key attestation on iOS, Google Play Integrity on Android. Per-request assertion headers verified server-side — replays and proxies get a 403.
Push notifications with deep-linking
APNS + FCM via expo-notifications. Lock-screen privacy enforced — no balance in the payload. Tap a notification, land on the receipt screen.
Virtual card management
Freeze / unfreeze, online payment toggle, ATM controls, and spending limits — all wired through your BFF.
Sentry + audit logs + feature flags
PII-scrubbed session replay, custom latency metrics per bank endpoint, server-side audit logs for every state-changing action, and gradual feature flag rollout.
EAS Workflows — lint, build, submit, OTA
On-PR lint + test, on-tag production build + store submit, OTA bundle updates, and forced-update flow driven by a server version manifest.
Tools production fintech teams actually use.
Every library in this course was chosen because it appears in real banking codebases — not because it's trendy.
You don't just finish. You ship.
Most courses end with a certificate. This one ends with four tangible artifacts you built under real constraints — the kind of proof that speaks louder in a job interview or client pitch than any completion badge.
The capstone isn't optional. You graduate by submitting a public monorepo, a threat-model doc with at least 10 STRIDE entries, an end-to-end video walkthrough, and a security audit PR on a peer's repo — written evidence that you understand what you built and why it's secure.
