Part-Time Full-Stack Technical Lead / Fractional CTO – U.S. Only

U.S.-BASED APPLICANTS ONLY I am a business owner with a few software/app projects. I understand my industries, customers, and what I need the products to accomplish, but I am not a software developer. I am looking for an experienced part-time Technical Lead / Fractional CTO who can represent my side of the development process and help manage the technical execution of my projects. This is not primarily a programming position. I already use developers for implementation. I need someone experienced enough to understand the applications, translate my business requirements into clear technical specifications, communicate directly with developers in technical terms, review their work, and tell me whether what I'm being told and delivered is correct. What I need from you Understand what I want the product to accomplish from the user's/business perspective. Turn those requirements into clear technical specifications and milestones. Communicate directly with developers and handle technical discussions that don't require my involvement. Review existing codebases, architecture, APIs, databases and deployment setups. Review proposed solutions before developers spend significant time implementing them. Review code and completed milestones and tell me whether the work is actually complete before I approve payment. Identify unnecessary rebuilds, poor architecture, security problems, technical debt or developer shortcuts. Help evaluate and interview developers when I need additional specialists. Coordinate multiple developers when appropriate. Make sure repositories, hosting, domains, databases, APIs, Apple/Google developer accounts and other critical assets remain under my company's ownership and control. Help take applications through Apple App Store and Google Play production releases when necessary. Technical background You do not need to personally be the best developer in every technology involved, but you need enough hands-on technical experience to confidently oversee developers working with technologies such as React Native, iOS/Android, JavaScript/TypeScript, Node.js/Express, APIs, databases, authentication/security, cloud deployment, PWAs, Git/GitHub, mapping/GPS, AI/LLM integrations, and App Store/Google Play deployment. Experience with logistics, transportation, mapping/navigation, marketplaces or SaaS products would be particularly valuable. Working relationship This will begin as a part-time position. I am not looking for someone doing routine programming 30–40 hours per week. I want someone I can use when I need technical leadership: reviewing a project, defining work, talking with developers, checking a milestone, resolving a technical disagreement, or helping select the right approach. Occasional face-to-face meetings are important to me. Much of the work can be remote, but I specifically want someone U.S.-based who is willing and able to meet with me periodically. When applying, please answer: Where are you physically located? Are you willing to meet with me in person periodically? Describe your experience leading or supervising software developers. Have you inherited existing applications/codebases and evaluated another developer's work? Give examples. What mobile applications have you personally helped take to production on both Apple App Store and Google Play? How comfortable are you reviewing React Native, Node/backend, database, API and cloud architecture? Describe any mapping/GPS, logistics, transportation or marketplace applications you've worked on. How do you determine whether a developer's milestone is genuinely complete before recommending that the client approve it? How would you protect a business owner from becoming dependent on a developer who controls the repository, hosting, database or other critical infrastructure? Are you comfortable communicating directly with overseas developers and leading technical calls on my behalf? Please begin your proposal with the words OWNER SIDE so I know you read the posting. I am looking for a long-term relationship with the right person who could eventually become the technical person overseeing multiple existing and future products for my companies.
