How I Work

I Chase the "Impossible"

I'm drawn to the problems everyone else avoids. When something is labeled "can't be done," that's where I start. I built an AI scraper that works across 9,000+ sources — a challenge others considered unfeasible.

Relentless Efficiency

I obsess over eliminating waste — in code, in processes, in how teams spend their time. If there's a manual task being repeated, I'll automate it. If a query is slow, I'll find the bottleneck. Shipping fast without cutting corners is how I operate.

High-Impact Ownership

I don't wait to be told what to build. At Vortal, I independently conceived and architected an AI-powered scraper from scratch — designing the LLM pipeline, the distributed architecture with Azure Service Bus, and the Kubernetes deployment — turning a vague idea into a production system covering 9,000+ sources.

Build from Zero to Production

I thrive on greenfield projects. From architecting systems to choosing the right tools to deploying on Kubernetes with CI/CD — I've shipped complete products from scratch, including an AI-powered pipeline and a full ticketing system.

About Me

I'm a 24-year-old Software Engineer with professional experience since 2019. I'm passionate about tackling problems others consider "impossible" and turning them into elegant, working solutions.

Having traveled through 22 countries across 5 continents, I've developed a global perspective and strong cultural adaptability that shapes the way I collaborate and approach challenges.

From building AI-powered web scrapers that work across 9,000+ sources to designing production-grade database normalization scripts, I thrive at the intersection of creativity and engineering.

Work Experience

Software Engineer

Vortal
Oct 2025 – Present Lisbon, Portugal

Armilar Platform — European public procurement data aggregation system (15+ sources: TED, BASE, PLACSP, Junta de Andalucia, Euskadi, and more).

AI-Powered Scraper (Built from Scratch)

  • Conceived and built an innovative generic scraper using LLMs to dynamically generate XPath extraction rules — capable of working across 9,000+ sources without site-specific code, with automatic XPath regeneration when sites change
  • Multi-layer pipeline: HTML fetching (Playwright + proxy rotation), HTML optimization for LLM consumption, value extraction via XPaths
  • Producer/Consumer architecture with Azure Service Bus (MassTransit interop for C#) for distributed horizontal scaling
  • Deployed with Docker, Kubernetes (Helm charts), Azure Pipelines CI/CD with configurable replicas

Backend Development & Scrapers (.NET/C#)

  • Developed and maintained web scrapers for European procurement platforms using .NET/C# and ASP.NET Core
  • Designed and implemented the SourceUrlTransformer — a URL normalization engine that resolved tender duplication across Spanish and Portuguese portals
  • Implemented depth-level 3 insights with significant query optimizations
  • Fixed critical bugs across multiple scrapers

Production Database Engineering (SQL Server)

  • Created 4 production-grade data normalization scripts for tender deduplication, each handling 15+ related tables with full referential integrity preservation
  • Safe transaction management, impact analysis, and audit reporting
