Hey, I'm

Henrique Cardoso de Faria

Senior Software Engineer & Euruko 2025 Organizer

I've been shipping software for over a decade, mostly for startups and mostly remotely. Currently at BSPK in Portugal, where I architect AI-powered features for luxury retail clienteling. I also run HC Digital Services, helping companies integrate AI into their Rails applications.

My sweet spot is backend work with Ruby on Rails and Elixir/Phoenix, though I'm comfortable across the full stack. I especially enjoy building systems that connect LLMs to real data — making AI actually useful, not just impressive.

Based in Viana do Castelo, Portugal. When I'm not coding, you might find me organizing Ruby conferences — I helped bring Euruko 2025 to my hometown.

Experience

BSPK

Senior Software Engineer

Jul 2023 – Present · Remote

BSPK is the unified commerce AI platform for luxury brands — think Dior, Cartier-level clienteling. As the primary backend engineer, I've been building the AI layer from scratch while maintaining and evolving the core Rails application, Shopify integrations, and data pipelines.

AI Assistant

Built a multi-agent system using a swarm architecture. An orchestrator routes to specialist sub-agents (Client Intelligence, Tasks & Calendar) that use tools to query shopper data, purchase history, and schedules. Provider-agnostic — works with OpenAI, Groq, and local models.

Natural Language Search

Designed a system where LLMs translate plain English into Elasticsearch queries, letting sales associates search their client book conversationally — "show me clients who bought handbags last month and haven't been contacted."

Behavioral Analytics

Built an observability pipeline from scratch: API event capture across 270+ endpoints, session materialization, daily metric rollups, behavioral profiling, funnel analysis, and sales outcome correlation.

Shopify & Data Pipelines

Deep ownership of the Shopify webhook pipeline — order syncing, customer assignment to nearest stores via geocoding, staff member resolution, and data quality across the full lifecycle. Led Rails upgrades through 8.1.

HC Digital Services

Through HC Digital Services LLC, I help companies build and improve their software — from Rails applications to AI integrations. Whether you need to add LLM-powered features to an existing product, architect a new system, or level up your team's backend infrastructure, I can help.

AI Integration

Adding real AI capabilities to your product — not just chatbots. Agentic systems, natural language search, structured LLM outputs, and RAG pipelines that actually work with your data.

Rails Development

Full-stack Rails work: new features, API design, performance optimization, upgrades, and refactoring. Comfortable with large codebases and complex domain logic.

System Architecture

Data pipelines, Elasticsearch integration, background processing, real-time systems with PubSub, third-party API integrations (Shopify, payment providers, and more).

Get in touch

I'm always happy to chat about interesting projects, Ruby, AI, or anything in between.
