Open to remote Senior / Lead iOS roles

Native iOS for systems where correctness matters.

I build reliable mobile products across real-time FinTech, offline workflows and on-device intelligence—with native Swift experiences and well-tested Rust cores.

Review the code

Two public Swift 6 samples. No NDA hand-waving.

Small enough to audit in one sitting, deep enough to discuss in a system-design interview.

01

REAL-TIME FINTECH

FinStreamKit

Actor-owned market state, cancellation-aware streams, stale and out-of-order event handling, integer money and deterministic order-risk rules.

  • Swift 6
  • Concurrency
  • XCTest
  • CI

LOCAL-FIRST DOCUMENT AI

EvidencePipelineKit

PDFKit and Apple Vision OCR with confidence, provenance, deterministic retrieval, contradiction gates, citations and explicit human-review outcomes.

What I own

From architecture to App Store delivery.

A

Native product engineering

SwiftUI and UIKit, concurrency, adaptive iPhone/iPad UI, SPM, persistence, testing and release discipline.

B

Real-time and risk-sensitive flows

Market data, order entry, reconnects, freshness, execution state and UX that does not hide uncertainty.

C

Rust shared cores

Typed UniFFI/CoreFFI boundaries, immutable DTOs, deterministic logic and reproducible XCFramework builds.

D

On-device and document AI

AVFoundation, Vision, PDFKit, Core ML/ONNX, OCR and RAG pipelines designed to fail honestly.

Selected private work, described safely

Evidence beyond toy apps.

01

Native iOS + Rust offline platform

SwiftUI product backed by a 40-module Rust core, 209 unit tests, 14 integration tests, Core ML/ONNX delivery and reproducible Apple builds.

02

Camera PPG and real-time DSP

AVFoundation capture, signal-quality gates, stabilization, hysteresis, device validation and an honest non-medical product boundary.

03

OCR and decision automation

Apple Vision/PDFKit evidence extraction, source-health controls, deterministic parsing and time-based ML evaluation across 1,977 unique parcels.
