Miguel Ladines
AI Engineer — LLM Integration · Business Automation · Cloud Infrastructure
Bilingual Electronics Engineer (Spanish/English C2) with 5+ years across IT consulting, corporate IT infrastructure, scientific research, intelligent transportation, and banking. A systems-first approach shaped by that multi-domain background: architecture from the data layer to the business layer, weighed against what a decision costs or saves — not just whether it works technically.

About
I design, build, and deploy applied AI and automation solutions end to end, validated in production — not just prototyped. That multi-domain background across research, corporate infrastructure, and independent consulting shaped a systems-first approach: I think in terms of architecture, from the data layer to the business layer, and design accordingly.
💼 WHAT I FOCUS ON
- LLM IntegrationMulti-model AI platforms, self-hosted and API-based, taken from prototype to cloud deployment and validated end-to-end.
- AutomationWorkflow orchestration and reporting pipelines built to fail safely, with automatic validation and retries instead of silent errors.
- Cloud & DevOpsContainerized deployment and infrastructure as code, with every component validated on deployment, not assumed to work.
- AI-assisted developmentI use native AI tools (Claude Code) as part of my daily development workflow.
🛠️ HOW I WORK
- Architecture in writing before codeScoped, documented decisions so any team member can maintain the system, not just me.
- LLM output is untrusted until proven otherwiseGenerated content passes deterministic checks before anything ships.
- Pipelines fail closed, not openHealth checks block advancement on integrity failures instead of letting bad data reach a dashboard.
- Reproducible by defaultContainerized, version-pinned configs that behave identically across dev, staging, and production.
- Honest scopeExplicit about what's a prototype and what's in production.

How I can add value
02
Business Automation
Workflow orchestration and reporting pipelines that fail safely, with retries instead of silent errors.
03
Cloud Infrastructure
Containerized deployment and infrastructure as code — every component validated, not assumed to work.
04
Technical Documentation
FSR, SAD, ADRs, and C4 diagrams that scope a system in writing before a line of code exists.
§03
Featured projects
P-01
AI Reporting Pipeline
A fully automated weekly reporting pipeline for a multi-branch distribution business. n8n orchestrates the flow, an AI model generates the executive narrative, and a strict two-page PDF is rendered and emailed — with six staggered retries and a page-count assertion that blocks any malformed report from shipping.

Self-Hosted Multi-Model Chatbot
An AI chat platform deployed end to end on a Google Cloud VM — from a fresh Debian instance to a live HTTPS endpoint. OpenWebUI runs behind NGINX; every model call routes through OpenRouter for pay-per-token access to OpenAI, Anthropic, xAI, and DeepInfra, layered with UFW, VPC firewall rules, and a Shielded VM.

Insurance Analytics Dashboard
A modular Python pipeline that generates a synthetic insurance portfolio, validates data quality at every stage boundary, and loads a five-dimension star schema into a Supabase warehouse with row-level security — feeding four Looker Studio dashboards through a fixed-grain semantic layer.

GoldenMovies Booking Platform
A bilingual cinema-booking experience built on Next.js 16 App Router and React 19 Server Components — an interactive seat map with tiered pricing, shared Zod validation between client and server, per-IP rate limiting, and a documented path to a production data layer.

SmartCrops Hydroponic Architecture
A pre-development architecture package for a commercial Flood & Drain hydroponic system: a local-first IoT platform that runs all control logic on-site and syncs to a read-only cloud dashboard over an HMAC-signed, outbound-only channel — an ICS/SCADA-style trust boundary. Delivered as six C4 diagrams plus an FSR, SAD, and 14 ADRs.

Graduated 2018
Electronics Engineer · Caracas, Venezuela
Undergraduate thesis · Feb 2018 – Nov 2018
Autonomous Monitoring & Control System for Indoor Crops
A functional hardware, firmware, and mobile-app prototype for automated indoor-crop monitoring. A PIC18F2550 microcontroller runs deterministic C firmware for irrigation, lighting, aeration, and temperature/humidity regulation, reading a DHT11 sensor and driving actuators through custom control logic. A custom Bluetooth protocol streams telemetry to a companion Android app ("SmartGrowth," built in MIT App Inventor) for real-time monitoring and configuration. It's the conceptual predecessor to the later SmartCrops hydroponic architecture project, built roughly seven years later.
