Secure Authentication Best Practices for Fintech Apps (2026)
Secure authentication for fintech apps: passkeys, biometrics bound to Keychain keys, Secure Enclave device binding, step-up for transfers, safe recovery.
In-depth articles on iOS app development, cross-platform solutions, cost optimization, and mobile architecture. Each one comes out of a decision I've had to make on a real app.

Sanctum or Passport for a Laravel mobile API: when per-device Sanctum tokens are enough, when you need OAuth2 with PKCE, and how to rotate tokens.
Build a Laravel API your iOS, Android and Flutter apps can rely on: per-device Sanctum tokens, versioning that keeps old builds working, sync and push.
A decision framework for choosing between a mobile MVP and a full build, based on what you are actually trying to learn and what failure costs.
iPhone app development timeline: 3-5 weeks for a prototype, 4-8 weeks for an MVP, 4-8 months for a production app, plus App Store review and phases.
React Native app development cost in 2026: budget ranges by app complexity, the native-module tax, and what maintenance costs after launch.
Flutter app development cost in 2026: MVP and production budgets, what drives the number up, and where Flutter is genuinely cheaper than native.
Structure a white-label iOS app so one Swift codebase ships as many branded apps: build configuration, theming, capability flags, CI, and release management.
Ruthless feature scoping, architecture decisions for speed, what to skip in v1, and a week-by-week plan to get to TestFlight fast.
Profiling with Instruments, lazy SDK init, asset optimization, and architecture changes to hit sub-1s cold start on iOS and Flutter.
Auth lifecycle, API hardening, data storage encryption, jailbreak detection, logging rules, and incident response readiness.
Production-ready API hardening checklist for mobile backends: authentication lifecycle, policy enforcement, abuse control, logging, and incident readiness.
Step-by-step migration strategy for UIKit apps: architecture bridge, phased rollout, testing gates, and risk control while continuing product delivery.
Framework selection guide for product teams: compare Flutter and React Native by performance, team fit, release speed, and long-term ownership cost.
Complete pricing guide: MVPs ($15K-$40K) to enterprise apps ($150K+). Learn what factors affect costs, hidden expenses, and how to optimize your budget.
These are the problems I get hired for. If one of them is yours:
