Senior iOS Engineer @ Ajaib | Cross-market trading apps (US Stocks) | Six years shipping production iOS at scale

I build the trading surfaces people trust with their money. At Ajaib (@ajaibid), I ship cross-market iOS features across four markets, including full US Stocks support, and refactored the core trade page from 415ms → 328ms on a scalable architecture.

My craft is modern SwiftUI at scale. I build features with The Composable Architecture (TCA): state flows in one direction through pure reducer functions, asynchronous work runs on Combine pipelines, and every feature decomposes into isolated, unit-testable modules. Clean Architecture keeps domain, data, and presentation independent so business rules stay framework-free. Tuist manages our modular Xcode projects, keeping build times fast and deterministic.

Off the clock, I build fintech apps and real-time market tools.

Beyond production iOS engineering, I design and operate large-scale autonomous agent systems, managing over 400+ subagent orchestrations across intensive engineering rallies with strict security gates, cost governance, and execution speed.

• Frameworks & Engine Tools: Advanced lifecycle management and orchestration using Hermes Agent Engine, Google Antigravity (AGY) SDK, custom subagent dispatchers, and persistent state databases.
• High-Throughput Execution: Over 400+ specialized subagent invocations orchestrated for deep codebase analysis, security vulnerability audits, automated test suites, and documentation generation.
• Autonomous Holding Roster (17 Core Agents): Structured workforce spanning Executive Leadership (CEO, CTO, CPO, CFO, CMO, CISO), Management, Staff Engineering, and Security Watchdogs.

• Central Control Command Center: Live telemetry dashboard at wiradifit-studio.duckdns.org tracking token quotas, agent heartbeats, zero-trust security, and system metrics in real time.
• Social & Content Distribution Engine: Automated multi-account social media dispatcher for content generation, image asset formatting, and scheduled queue publishing.
• Token Treasury & Router Sentinel: Smart multi-model LLM router with dual-pool quota enforcement, failover routing, and daily token reset sentinels.
• Multi-Cloud Edge Infrastructure: Oracle Cloud ARM Ampere A1 primary hub (PostgreSQL 16, Redis 7, local vector embeddings, systemd background services) paired with a hardened Tencent Cloud edge node (Caddy, fail2ban, UFW security rules).

I deploy and operate multi-agent workflows across mobile, backend, data, and cloud infrastructure with focus on architecture, security, cost control, and leverage.

I run a permanent, automated bug-bounty operation across the open-source Swift ecosystem: high-star SwiftUI packages and apps are continuously audited for real bugs (Swift 6 strict-concurrency violations, retain cycles, force-unwraps on failure paths, error-handling defects), and every confirmed fix is verified on real Apple toolchains before submission.

Every fix PR ships with receipts: compiled on macOS 15 + latest-stable Xcode, tests green, CI run linked. Companies and maintainers: if your Swift package needs hardening or an audit, my contact is below — this is exactly what I do for a living.
