20-year Solution Architect and Fractional CTO helping Series A–C SaaS scale-ups and Fortune 500 teams ship cloud-native, AI-powered systems that don't break at 10× load. DevOps, Software Architecture, AI consulting — delivered, not theorized. If your roadmap has any of these on it — a cloud migration that's slipping, an AI/LLM feature that demos well but won't survive production, a monolith you need to break up without freezing the product team, or a DevOps platform that's burning cash and on-call time — I've shipped that exact engagement before, more than once. What I do (and have done for 20 years): ✅ Solution & Software Architecture — system design, domain modeling, microservices vs. modular monolith trade-offs, event-driven & API-first platforms, architecture reviews and ADRs your team will actually follow ✅ DevOps, Cloud & Platform Engineering — AWS / Azure / GCP, Kubernetes (EKS/AKS/GKE), Terraform, CI/CD, FinOps cost reduction, SRE / observability, zero-downtime migrations ✅ AI Consulting & AI Solutions Architecture — production LLM / RAG systems, agentic workflows, AI strategy roadmaps, build-vs-buy decisions, model selection, evaluation harnesses, vector DBs, secure enterprise AI ✅ Fractional CTO & Tech Due Diligence — for founders pre-Series A through Series C; for PE / VC pre/post-investment For startups & scale-ups: I move at founder-speed. MVP architectures that won't need a rewrite at Series B, AI features you can actually ship, hiring plans for your first 5 engineers, and an architecture roadmap your investors will respect. For enterprises: I bring TOGAF-style rigor without the consultancy bloat — solution architecture, cloud migration strategy, vendor-neutral AI roadmaps, security/compliance-aware design (SOC 2, ISO 27001, HIPAA, GDPR), and stakeholder-ready documentation. Selected outcomes from the last 20 years: 🏆 Cut cloud spend 41% and shortened deploy time from 45 minutes to under 5 minutes for a SaaS platform serving 12M users 🏆 Designed the AI/RAG architecture that took a B2B SaaS from PoC to production with 30+ enterprise customers in 5 months 🏆 Re-architected a legacy monolith into modular services with zero customer-facing downtime over 7 months 🏆 Led DevOps platform builds (Terraform + Kubernetes + GitOps) that cut on-call pages by 70% and onboarding from weeks to days How I work: small commitments first. Most engagements start with a paid 60-minute architecture call or a 1–2 week assessment, so we both know it fits before you commit to a long retainer. I write things down. I document decisions. I leave your team better than I found it. What I won't do: rewrite-the-world projects with no executive sponsorship, "just do everything yourself" engagements with no engineering team to hand off to, or AI demos that aren't on a path to production. Send me a paragraph about your stack, your team size, and the outcome you need in the next 90 days. I'll come back inside 24 hours with a short, specific point of view not a sales pitch. If we're a fit, we'll book a working call from there.
