Are you a non-technical founder or business owner with a clear vision, but no desire to manage a dev team? As a Fractional CTO and Lead Architect with 15+ years of experience, I take your software from napkin sketch to live production. I operate at the intersection of senior engineering and executive technical leadership. My role is to act as your "Tech-to-Business Translator" - converting your commercial objectives into scalable, high-performance architecture without the confusing jargon, giving you absolute visibility over your product. I leverage advanced AI tooling and strict architectural standards as a development force multiplier. This means you get the execution speed, output, and reliability of a full engineering team through a single, highly accountable expert. No coordination overhead. No junior-dev babysitting. No technical black boxes. THE TERMS OF ENGAGEMENT: * The 14-Day Mutual Alignment Guarantee: Software architecture requires absolute trust. If you are not completely satisfied with my execution, or if our communication styles do not perfectly align within the first two weeks, I issue a 100% refund, no questions asked. * Async-First Execution: I protect your budget by protecting my focus. We hold one highly structured weekly alignment call to review progress. All daily communication and updates are handled asynchronously via text or Loom video. You pay for engineering throughput, not meeting bloat. * Clean Handoff & IP Sovereignty: You hold the root infrastructure keys and own 100% of the source code and intellectual property from day one. No proprietary vendor lock-in. * 30-Day Code Warranty: I stand by my architecture. I patch any bugs within the delivered scope for free for 30 days post-launch. WHAT I ARCHITECT & DELIVER: * Core SaaS MVP Development: Lean, zero-dependency, hyper-fast systems designed for rapid market validation. * Deterministic AI Integrations: Production-grade LLM pipelines, autonomous subagents, and secure RAG systems built to eliminate hallucination risks. * Bulletproof Backend APIs: Robust, highly secure data layers and infrastructure designed to support complex web and mobile frontends. * High-Efficiency Infrastructure: Cost-effective self-hosted deployments (Hetzner, Docker, Traefik) that keep your ongoing server overhead near zero.
