Get senior, hands-on help when you inherit an unfamiliar codebase, lose a development partner, face recurring production problems, or need clearer technical direction. I review mobile and full-stack systems, explain the tradeoffs, and help turn findings into practical engineering work. My background spans React Native, Next.js, Swift, Kotlin, Node.js, Firebase, and PostgreSQL, including full-stack delivery and lead mobile engineering responsibilities. Engagement options • Codebase and architecture assessment: review application structure, integrations, data flows, dependencies, and the concerns affecting your product. • Prioritized recovery plan: document findings, identify risks, and recommend a sequence for stabilization, maintenance, or modernization. • Hands-on implementation: address agreed issues, improve selected parts of the system, and document changes for continued development. • Fractional CTO support: provide ongoing architecture guidance, technical planning, engineering reviews, and support for product and vendor decisions. We begin by defining the problem, available access, and the decisions or deliverables you need. After the initial review, we agree on implementation scope and priorities. The work can remain a focused assessment or continue into ongoing technical leadership and delivery. Consulting is $100/hour. Scope and estimated effort are agreed before work begins.
