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.

Most clients find me after wasting weeks on engineers who deploy fast but leave security gaps, brittle scripts, and zero documentation behind. Well, I do the opposite. I'm a DevSecOps engineer with 7+ years building cloud infrastructure that is production-hardened from day one, not secured as an afterthought. AWS, Kubernetes, CI/CD, secrets management, container security, GDPR-compliant workflows, all of it built clean and documented properly. I'm also one of the few engineers who builds AND secures AI agent systems. LangChain, CrewAI, RAG pipelines, MCP servers, I understand the attack surface of modern AI infrastructure that most security engineers have never touched. 🔐 Security & DevSecOps 🔹 Linux Hardening: firewalls, iptables, SSH lockdown, fail2ban, SSL/TLS 🔹 Secrets Management: HashiCorp Vault, AWS Secrets Manager, Azure Key Vault, GCP Secret Manager 🔹 Container Security: Docker Hardening, Kubernetes RBAC, Network Policies, Pod Security Standards 🔹 Server Management: WHM, cPanel, Plesk, Webmin, Virtualmin 🔹 GDPR-ready Workflows: encrypted APIs, secure backups, access control 🔹 CI/CD Security: secrets scanning, signed images, GitHub Actions, GitLab CI, Jenkins ☁️ Cloud Infrastructure & DevOps 🔹 AWS, GCP, Azure, DigitalOcean: deployment, scaling, cost optimization 🔹 Infrastructure as Code: Terraform, Pulumi, Ansible 🔹 CI/CD pipelines: GitHub Actions, Jenkins, GitLab CI 🔹 Container orchestration: Docker, Kubernetes, Helm 🔹 GitOps: ArgoCD, Flux 🤖 AI Infrastructure & Automation 🔹 Multi-agent systems: LangChain, LangGraph, CrewAI, AutoGen 🔹 Model Context Protocol (MCP) server integration 🔹 RAG pipelines & vector search: Pinecone, Qdrant, Weaviate, ChromaDB 🔹 LLM app builders: Dify.ai, Flowise 🔹 Multi-model routing: OpenRouter 🔹 AI agents: Claude, ChatGPT, Gemini, Azure OpenAI, AWS Bedrock 🔹 Local LLMs: Ollama, Mistral, Llama on Linux servers 🔹 Workflow automation: n8n, Make, Zapier, APIs & webhooks 💻 Full Stack & WordPress 🔹 Backend: Laravel, Node.js, Java, NestJS, Python, Go 🔹 Databases: PostgreSQL, MySQL, MongoDB, Redis 🔹 WordPress: Elementor, Divi, Bricks, Oxygen, WP-CLI, Gutenberg, Headless WordPress 📊 Monitoring & Reliability 🔹 Observability: Prometheus, Grafana, OpenTelemetry, ELK Stack, Sentry, CloudWatch 🔹 Automated backups: Rclone, AWS S3, GCP buckets 💼 You're a great fit if you are: 🔹 A startup that needs infrastructure secured from day one 🔹 An agency that wants one reliable long-term technical partner 🔹 A business running AI agents that needs someone who understands both the build side and the security risks Tell me what you're building.

Top Rated Solutions Architect I build, scale, and rescue production systems for SaaS products, AI applications, and teams outgrowing their current infrastructure. Most engineers can ship features. I build systems that hold up under real load and fix the ones that don't. Where I help: Slow, breaking, or unreliable backend systems Scaling problems and messy cloud infrastructure AI and RAG systems that need to run reliably in production Complex integrations with APIs, payments, data pipelines, hardware Migrations between cloud providers without downtime Recent work: Architected and migrated production infrastructure across AWS, GCP, and DigitalOcean Built a RAG-based internal tool that lifted a 30-person team's productivity by 22.5% Hosted and migrated a 10TB+ dataset with zero data loss Designed distributed multi-region processing systems handling concurrent workloads Built a SaaS platform doing $10K+ monthly recurring revenue Shipped 5+ CI/CD pipelines for teams that previously deployed by hand Stack: Cloud: AWS, GCP, DigitalOcean, Contabo, Cloudflare Backend: Python (FastAPI, Flask, Django), Celery, Docker, Redis Data: PostgreSQL, MongoDB, Supabase, GraphQL, vector databases AI: RAG pipelines, LangChain, LlamaIndex, OpenAI/Anthropic, Ollama How I work: I take ownership of outcomes, not just tickets. You get clear technical direction, structured execution, and a system that's still working six months later. Send me a message with what you're building or what's breaking. I'll reply with a technical approach and the fastest path to a stable solution.
