Daniel White

I’m a Senior Full-Stack Software Engineer and AI Solutions Architect with 15+ years of experience building production web applications, mobile apps, SaaS platforms, cloud infrastructure, and AI-powered systems.

I work with startups, founders, and established businesses to take products from idea or prototype through production, as well as step into existing applications that need stabilization, new features, modernization, or technical leadership.

My core services include:

• Full-Stack Web Development: React, Next.js, TypeScript, Node.js, APIs, authentication, dashboards, and complex application workflows

• Mobile App Development: React Native, Flutter, Expo, and cross-platform iOS/Android development

• AI & Agentic Systems: LLM integrations, AI assistants, autonomous workflows, RAG, tool calling, MCP, structured outputs, AI automation, and custom AI features

• Backend & API Development: Node.js, Go, REST APIs, integrations, webhooks, background processing, and scalable service architecture

• Cloud & Infrastructure: Google Cloud Platform, Firebase, Supabase, PostgreSQL, serverless architecture, CI/CD, monitoring, and production deployments

• SaaS & Marketplace Development: subscriptions, Stripe and Stripe Connect, user roles and permissions, admin systems, reporting, payments, onboarding, and multi-tenant workflows

• Existing Application Rescue: debugging AI-generated or legacy codebases, fixing broken workflows, reducing technical debt, improving performance, and getting unfinished products ready for production

• Technical Leadership: architecture, code reviews, engineering standards, technical planning, security, QA strategy, and fractional CTO/technical lead support

I’m especially comfortable working with founders who have built an initial product using tools such as Cursor, Claude Code, Lovable, v0, or other AI-assisted development platforms but need an experienced engineer to turn that work into a reliable production system.

I’ve worked across healthcare, SaaS, e-commerce, fintech, mobile applications, AI systems, marketplaces, and enterprise software. My focus is not simply writing code. I help determine what should be built, design the architecture, implement it, test it, deploy it, and make sure it can continue to grow.

Whether you need a complete application, an AI feature, help launching an MVP, or a senior engineer to take ownership of an existing codebase, I can work with you from technical planning through production.
