About Axel Soedarsono

I’m an iOS Engineer with 5+ years experience in building scalable, mobile architectures across fintech and KYC flow. My expertise spans Swift, SwiftUI, UIKit, Objective-C, modular architecture, networking layers, and system observability. At Traveloka PayLater, I’ve led and delivered end-to-end features across acquisition, repayments, KYC verification, and compliance-Designed and implemented a fully custom KTP & Selfie capture pipeline (camera architecture, luminance detection, OCR integration, retry logic), significantly reducing verification errors -Modernized the PayLater Account, Repayment, and Transaction History flows using SwiftUI + UIKit bridging, WKWebView integration, and performance optimizations - Built and extended networking + logging layers with Datadog, improving error surfaceability through structured logging, missing error-code capture, and shared dashboards -Added Partial Repayment, Digital Signature, Grant Offering Limit, and other high-impact flows tied deeply to scoring, OJK requirements, and payment logic -Integrated SDKs such as Credolab and Datavisor, ensuring secure data handling and stable performance within the Traveloka PayLater -Drove SwiftUI adoption, contributed to UI testing strategy, and onboarded new engineers as team Buddy Before Traveloka, I developed Objective-C–based features at Moselo, working heavily on custom UI, animations, AutoLayout, and end-to-end API integration. This foundation enabled me to bridge legacy Objective-C systems with modern Swift codebases effectively. I’m passionate about architectural clarity, cross-module communication, debugging distributed systems, and mentoring engineers to build sustainable, future-proof features at scale.
