Fractional CTO / Technical Advisor
Get senior technical leadership for a real build in motion: architecture decisions, MVP planning, AI strategy, vendor review, codebase rescue, technical due diligence, handoff, and practical roadmap guidance tied to implementation.
A fractional CTO or technical advisor helps when the next decision affects an active software project: hire, rebuild, continue with a vendor, add AI, rescue a codebase, or ship an MVP. The work is practical and evidence-based: inspect the current state, identify the real risk, and define the next technical move.
Define what to build first, what to defer, what stack fits, and what risks must be resolved before a funded build scales or enters pilot.
Review estimates, deliverables, code quality, architecture, security risk, and whether the current plan makes technical sense.
Decide whether to patch, stabilize, refactor, rebuild, or pause before more money goes into a brittle system.
Identify where AI belongs, where it does not, and what data, workflow, evaluation, and infrastructure must surround it.
Review architecture, backend decisions, mobile stack, scalability, deployment, security posture, data model quality, and maintainability.
Translate committed product goals into technical plans, tradeoffs, vendor questions, and decisions a nontechnical founder or operator can act on.
Inherited a chaotic prototype and helped re-architect it into a secure surgical readiness platform that progressed to funded pilot deployment with live clinical workflows.
Joined NASA WeatherSats AR midstream, stabilized the Unity/AR codebase, provided progress updates, fixed production defects, and helped ship across iOS and Android.
View ProofBuilt Azure/Power BI reporting for a NASA internal team with role-level security, automated data pipelines, documentation, and technical handoff for analysts and engineers.
Founded and built CRAFT across iOS, Android, web, and Firebase; also took over stalled or inherited projects including Cellf Defense, Word Game, and client mobile rebuilds.
Built a self-hosted coding AI portal concept around retrieval, evals, safety, rate limits, backend infrastructure, local models, and human handoff.
View ProofMake clear decisions around mobile, web, backend, Firebase, PostgreSQL, SQL Server, FHIR, APIs, cloud infrastructure, AI, and data models.
Turn business goals into technical phases, risk areas, milestones, and a realistic build order.
Review existing systems, vendor work, AI-generated code, platform decisions, security concerns, release readiness, and developer handoff risk.
Move past advice when needed by debugging, prototyping, implementing, reviewing, stabilizing, documenting, or shipping the system.
No. The work can include code review, implementation, debugging, architecture, vendor review, and technical writing.
This service is best for funded teams or active projects with code, vendors, MVP scope, AI features, or implementation decisions already in play.
Yes. I can review the current build, explain the risk, and help you decide whether to fix, continue, or reset.
