Hi, I'm a passionate and results-driven iOS Developer with 3–5 years of hands-on experience building secure, high-performance mobile applications for the banking and financial services industry. I specialize in crafting seamless, intuitive, and regulation-compliant iOS experiences that users trust with their most sensitive financial data.
What I Do
I design and develop native iOS applications from the ground up using Swift and Xcode, with a deep focus on security, scalability, and clean architecture. My background in fintech means I don't just write code — I understand the business logic behind it. Whether it's a digital wallet, a mobile banking app, a lending platform, or a personal finance tool, I know what it takes to ship a product that meets both user expectations and regulatory requirements.
My Core Expertise
Over the years I've built and contributed to features like real-time fund transfers, account dashboards, biometric authentication, transaction history, loan applications, KYC/onboarding flows, and push notification systems for financial alerts. I'm well-versed in integrating payment gateways, open banking APIs, and third-party financial SDKs, and I take security seriously at every layer — from certificate pinning and keychain storage to end-to-end encrypted communications.
I follow clean architecture principles (MVVM, VIPER, or Clean Swift depending on the project), write testable and maintainable code, and I'm comfortable working within Agile teams or independently managing a project end to end.
Why Fintech?
Financial apps carry a level of responsibility that most other categories don't. Users trust these apps with their livelihoods, and I take that seriously. I've worked in environments where compliance with standards like PCI-DSS and GDPR wasn't optional, and I bring that same rigor and accountability to every freelance engagement. I know how to navigate tight deadlines without cutting corners on quality or security.
Tools & Technologies
I work daily with Swift, UIKit, SwiftUI, Combine, CoreData, Keychain, REST APIs, and Firebase. For project delivery I use Git, Jira, Fastlane, and CI/CD pipelines to ensure smooth, reliable releases. I'm also experienced with App Store submission, TestFlight beta management, and crash monitoring through tools like Crashlytics.
What You Can Expect From Me
When you work with me, you get a developer who communicates clearly, delivers on time, and treats your project with the same ownership and care as if it were my own product. I ask the right questions upfront, provide realistic timelines, and keep you updated throughout the process. I'm not just here to write code — I'm here to help you build something that works, scales, and stands out.
Let's Build Something Great
If you're looking for an iOS developer who understands the nuances of fintech, takes security and compliance seriously, and can hit the ground running — I'd love to hear about your project. Feel free to reach out and let's discuss how I can help bring your vision to life.
