Raúl Mermans

I design and build decision systems that connect AI, data, product, and brand.

I use code to turn complex ideas, fragmented information, and ambiguous workflows into structured products, analytical tools, and digital experiences.

My work combines technical execution, business logic, visual judgment, and human-centered product design.


Selected Work

Operational simulation and decision-support product for testing service-workflow changes before implementing them.

OpsTwin compares operational scenarios—such as adding staff or reducing processing time—through paired simulations, uncertainty analysis, risk evidence, and structured decision outputs.

Role: Product design · Architecture · Implementation · Verification

Focus: Operational intelligence · Simulation · Decision support · Product engineering

Stack: Next.js · React · TypeScript · FastAPI · Python · SimPy

Live Demo · Guided Workspace


Evidence-bounded website intelligence system that captures public signals, generates deterministic findings, and translates them into structured strategic insights.

The product combines browser automation, scoring systems, AI synthesis, and report generation to move from raw website evidence to actionable recommendations.

Focus: Applied AI · Browser automation · Scoring systems · Strategic intelligence

Stack: Next.js · TypeScript · FastAPI · Python


AI-assisted campaign strategy workspace that transforms rough briefs into structured strategic routes, audience hypotheses, risk reviews, and execution-ready plans.

The system is designed around human review, structured generation, and clearer decision-making rather than one-click creative output.

Focus: Applied AI · Campaign strategy · Decision support · Human-in-the-loop workflows

Stack: TypeScript · React · Structured LLM workflows


Other Projects

  • Campaign Pulse — Marketing intelligence dashboard for campaign performance, audience pressure, revenue, targets, and segment movement
  • DataBrief AI — Spreadsheet intelligence and grounded business reporting
  • DemandOS — Demand forecasting and inventory-risk intelligence
  • BlogAgent — Evidence-aware editorial workflow system
  • TerritoryOps Spain — Real-estate opportunity and pipeline console
  • Benchmark Dashboard — Competitive benchmarking and scenario forecasting
  • Portfolio — Personal portfolio and case-study platform

What I Build

AI Products and Workflows

Structured generation, agentic workflows, validation systems, automation, internal tools, and human review.

Intelligence and Decision Systems

Simulation, forecasting, dashboards, reporting, campaign analytics, scoring systems, and operational intelligence.

Product and Brand Experiences

Product strategy, interface design, positioning, narrative structure, creative direction, and digital experiences.


Technical Stack

Languages Python · TypeScript · JavaScript

Frontend Next.js · React · Tailwind CSS · Vite

Backend and Data FastAPI · PostgreSQL · Pandas · SimPy · CSV/XLSX workflows · Machine-learning pipelines

AI and Automation LLM workflows · Structured outputs · Validation gates · Human-in-the-loop systems · Browser automation · Report generation


How I Work

I use code as a way to structure ideas.

Across my work, I connect:

  • Strategy with execution
  • Data with narrative
  • Automation with human judgment
  • Interfaces with decision-making
  • Technology with brand and culture

I am interested in building systems that help people understand complexity, evaluate alternatives, and act with greater clarity.
