Most cloud environments don't fail because of bad intentions they fail because reliability, security, and compliance were never engineered together from the start. That gap is where audits get delayed, production breaks under pressure, and teams scramble to fix what should have been built right. Over 13 years I have designed and operated cloud infrastructure for organizations where downtime and compliance gaps carry real consequences Bank of America, Fiserv, and the Federal Reserve Board. That experience shaped how I approach every engagement: secure architecture first, automation always, and reliability that holds up under scrutiny. Here's where I add measurable value: Cloud Architecture & DevOps: Designing resilient infrastructure on AWS and Azure, with Terraform-driven automation and Kubernetes orchestration that scales without becoming fragile. Site Reliability Engineering (SRE): Building observability, SLOs, and incident response practices that catch problems before customers do not after. Security & Compliance: Hardening environments against real threats while aligning with PCI-DSS, SOC2, NIST, and ISO 27001 the frameworks that determine whether your audit goes smoothly or doesn't. CI/CD & Infrastructure as Code: Standardizing deployment pipelines so releases are fast, repeatable, and don't depend on tribal knowledge. Whether you are a startup preparing for your first SOC2 audit or an enterprise team modernizing legacy infrastructure, I bring senior-level judgment with hands-on execution no handoffs, no gaps. Certifications: AWS Solutions Architect | RHCE | CCNA | CompTIA A+, N+, S+ Open to a quick call to review your current setup and identify exactly where the risk is.

I’ve delivered 200+ custom software solutions for Fortune 500 companies, US enterprises, founders, and funded startups across 38 countries, with a strong track record of client satisfaction. My work usually starts with building an MVP from scratch, scaling a product with traction, modernizing a legacy system, rescuing an unstable platform, improving performance, or integrating AI/new product capabilities without disrupting core operations. From there, I convert business goals, ROI expectations, user workflows, compliance needs, budget, and timeline into a development plan covering scope, milestones, architecture, integrations, testing/UAT, and rollout. For founders and funded startups, I help turn early product ideas, business models, and ROI expectations into a focused MVP scope, scalable architecture, launch roadmap, and growth plan without overbuilding too early. I design system, cloud, data, AI, SaaS, security, and integration architectures based on product stage, scalability needs, compliance requirements, operational complexity, and cost.

I help founders and software teams turn messy technical/product situations into clear execution: architecture, delivery, technical risk, team coordination, and reliable SaaS/backend/AI platforms. I’m not a “just give me tickets” developer. My strongest work is when a product needs someone who can understand the business workflow, challenge weak assumptions, design the architecture, coordinate developers, and still go deep enough technically to build or review the critical parts. Recent work includes: - Leading backend/platform work for an industrial AI/vision SaaS product using Java/Spring Boot, AWS event-driven services, Python/FastAPI, Claude/Anthropic, MCP tool integrations, secure auth, streaming UX, and production observability. - Building a multi-tenant RAG/chatbot SaaS on Google Cloud with FastAPI, NestJS, Next.js, Firebase Auth, Cloud Run, PostgreSQL, Cloud Storage, Vertex AI embeddings/search, strict tenant isolation, and SSE streaming. - Working in a fractional CTO-style consulting role: codebase audits, technical risk assessment, engineering standards, delivery process, roadmap/scoping, vendor/team coordination, and executive-ready recommendations. Typical areas where I help: - SaaS architecture and technical leadership - AI/RAG/LLM features that need to work in production, not just demos - Backend/cloud platforms on AWS or GCP - Multi-tenant systems, auth, data isolation, and workflow design - Turning vague requirements into clear technical execution - Reviewing existing codebases and identifying what to fix first - Leading or mentoring developers while keeping delivery moving - Communicating technical risks clearly to founders and non-technical stakeholders Core stack: Java/Spring Boot, Python/FastAPI, TypeScript/Node/NestJS, React/Next.js, AWS, GCP, PostgreSQL, Kubernetes, Terraform, event-driven systems, Claude/Anthropic, MCP, RAG, Vertex AI. Languages: fluent English, German, and Spanish. I’m open to focused part-time advisory work as well as larger long-term engagements when the project is serious, the scope is clear, and the collaboration is built around outcomes rather than busywork.
