// Invariants & Business Guarantees
Assertion::greaterThan($evaluatedAmount->cents(), 0);
}
}Enterprise Mobile Ecosystems
Native and hybrid deployments across Google Play & Apple App Store. Kotlin 2.1, Jetpack Compose, KMP 2.1, Capacitor 6/7, Trusted Web Activities (TWA), and Xcode Cloud CI/CD.
Applied AI & Autonomous Tool Calling
Production LLM orchestration with Gemini 3.7 Flash, Claude Opus 5 / Sonnet 5 & GPT 5.6 (Sol, Terra, Luna) APIs. Deterministic function calling, structured JSON output validation, webhook pipelines, and zero-hallucination guardrails.
Cloud Infrastructure & Zero-Cost Deployments
Astro 5.4 SSG, Cloudflare Pages & CDN, Docker containerization, Nginx reverse proxies, Linux systems, and automated CI/CD delivering instant execution with zero server cost.
Software Engineering Experience
Professional timeline delivering production systems across enterprise backends, mobile ecosystems, and applied AI architectures.
