How I deliver
You don't need four vendors. You need one senior engineer who owns the full stack — from the AI layer to the deploy pipeline.
Design and development of AI agentic workflows using LLMs and the Vercel AI SDK. MCP server deployment and hosting, agent orchestration, retrieval-augmented generation (RAG). Hands-on experience with Google Vertex AI, Azure AI, and Langfuse for observability.
Production Node.js/TypeScript APIs in Kubernetes environments. Domain-Driven Design (DDD) with hexagonal architecture. NF525 fiscal compliance, distributed systems across multiple European markets. Nx and Bun.js monorepos.
React, Next.js, and Remix interfaces on complex business workflows. From drag-and-drop builders to real-time data visualization with advanced filtering. 8+ years in the JavaScript/TypeScript ecosystem.
GitHub Actions CI/CD pipelines, Coolify and ArgoCD deployment. Datadog, Grafana, Sentry, and CloudWatch observability. K6 performance testing to validate production readiness and scalability.
