Shai A.

Founders bring me the software projects where generic development is not enough: production AI, complex custom platforms, inherited codebases, stalled delivery, and ecommerce or mobile products that must work reliably. I lead the technical work directly, from architecture and implementation through QA, integration, release, and recovery.

Selected experience includes direct Azure platform work for Microsoft through Upwork and a direct design contribution to NASA's Mars mission tool. Across 18 years, I have delivered work for startups, established businesses, and enterprise clients in the United States and internationally.

WHAT I BUILD AND FIX

• AI agents, AI enabled product features, workflow automation, evaluation controls, human approval flows, and system integrations
• Custom SaaS, web applications, backend platforms, ERP and CRM systems, dashboards, and internal business software
• iOS and Android applications using React Native, Flutter, Swift, and Kotlin
• WordPress, WooCommerce, Shopify, Shopify Plus, custom themes, plugins, apps, and ecommerce integrations
• REST APIs, GraphQL APIs, webhooks, OAuth, payment gateways, CRM, shipping, accounting, and third party integrations
• Architecture reviews, code audits, performance work, modernization, migration planning, and failed project recovery

CORE STACK

React, Next.js, JavaScript, TypeScript, React Native, Node.js, PHP, Laravel, WordPress, WooCommerce, Shopify, Flutter, Swift, Kotlin, REST API, GraphQL, MySQL, PostgreSQL, AWS, Azure, and common business platforms.

WHEN I AM MOST USEFUL

• An AI prototype needs to become a controlled production system
• A previous vendor missed deadlines or left behind unclear code
• A custom platform needs an experienced technical lead who can also implement
• A business process needs automation without losing human oversight
• A WordPress or Shopify system needs custom development, integration, stabilization, or scale
• A founder needs a straight answer before committing more time and money

HOW PROJECTS RUN

I start by identifying the actual business outcome, current constraints, and highest risk assumptions. I turn that into clear scope, milestones, and acceptance criteria. You see progress, test work, and approve major transitions before the next phase. Communication stays direct, calm, and written wherever possible.
