Project

Q5id

A challenging cross-platform integration project: identity proofing built from custom native bindings, biometric SDK integrations, hardware-dependent capture flows, and a complex API contract. This project had excellent .NET architecture -- MVVM, DI, UI Tests, Integraton Tests. I'm proud of the work we did on this app and will always defend it. We were ready to sign with US Bank and an unnamed country in Central America (election ID), and then COVID hit effectively stalling needed momentum.

Q5id identity verification flow showing facial biometrics, palm biometrics, voice biometrics, ID scan, fraud review, and advisor interview screens. — Multi-step identity proofing across native biometric SDKs, document capture, KYC checks, API orchestration, and advisor handoff.

Problems solved

Built and maintained multiple custom native bindings so Xamarin Forms could coordinate third-party biometric SDKs on iOS and Android.
Integrated face, palm, voice, ID capture, KYC provider data, and human review into one identity-proofing workflow backed by a complex API.
Managed hardware-dependent camera/media behavior, release pipelines, Azure DevOps CI/CD, and UI testing for production mobile delivery.
