Security-critical iOS, built by someone who's shipped to millions.
16 years of iOS, specialized in regulated industries: fintech, healthtech, digital identity. I built the BNPL and credit card features in Żappka, Poland's biggest retail app with 8M+ users. Available for your project.
Three ways I can help.
iOS App Development
SwiftUI, UIKit, TCA — from greenfield builds to augmenting your existing team. Production-grade architecture that scales.
Fintech & Payments
BNPL and credit card features, RSA encryption, JWT, JWKS verification, token rotation. Security-critical features most iOS devs won't touch.
AI-Accelerated Delivery
Claude Code-assisted workflow. Same quality bar, faster shipping. Modern tooling for modern timelines.
