Ennio Maldonado
I build AI systems
that go to production.
Senior AI Platform Engineer at Monarch. 12+ years in engineering across five countries. I design and deploy LLM platforms, RAG architectures, and agentic workflows for companies that need them working, not just demoed.
Get in touchCommon situations
Where I typically
get called in
These are the problems I solve most often.
Pilots that never ship
Most AI projects stall between demo and production. The model works in a notebook but nobody built the infrastructure to actually run it. That's where I come in.
No clear technical direction
RAG vs. fine-tuning vs. agents. Build vs. buy. Your team has ideas but no one with hands-on experience to make the call. I've built all of these and know when each one fits.
Senior AI talent is hard to find
A full-time AI engineering hire takes months and costs $250K+. I work on a fractional basis so you get senior-level execution without the hiring timeline.
What I do
Services
I work with companies at different stages of AI adoption.
Assessment & Roadmap
I review your data, infrastructure, and team capabilities, then identify the AI use cases worth pursuing. Deliverable is a prioritized plan with timelines, not a slide deck.
Build & Deploy
I architect and ship production AI systems. RAG pipelines, multi-agent orchestration, LLM integrations, evaluation frameworks. I work with your engineers until it's running and they own it.
Fractional AI Engineering
Ongoing embedded partnership, typically 2-4 days per month. Architecture decisions, code reviews, team upskilling, and identifying the next high-value use case.
Process
How engagements work
Straightforward, every time.
Intro call
30 minutes. You tell me what you're working on, I tell you if and how I can help. No cost, no commitment.
Scoping
I review your stack, data, and team. Then I put together a concrete engagement plan: what we build, how long it takes, what it costs.
Execution
I work alongside your engineers until the system is in production and your team can maintain it independently.
Background
12+ years building
systems at scale
From automotive engineering at Bosch and Continental in Germany to AI platforms at Monarch and Roofstock in the US.
AI-Powered Financial Assistant
Full-stack AI assistant for a fintech company handling all user interactions with the platform, from inputs to outputs. End-to-end: design, development, deployment.
Self-Serve Knowledge Base Platform
Enterprise platform that lets engineering teams manage their own knowledge bases through an admin API on gRPC endpoints. Built for scale and self-service.
Production Summarization Service
Text summarization API that accepts arbitrary content with tunable parameters to control output length, tone, and focus. In production, serving real traffic.
