Hi, I'm Pablo 👋

I'm a Software Engineer focused on backend development, distributed systems and software architecture. Most of my experience comes from fintech environments, where I have worked on scalable services, financial products, onboarding flows, PSD2-related initiatives and backend platforms.

I enjoy building systems that combine strong engineering foundations with practical product value: clean APIs, reliable data models, event-driven thinking, cloud-native services and increasingly, AI-powered workflows.

AI-assisted investment portfolio platform built as a microservices ecosystem.

The system combines backend services, financial data ingestion, AI agents and a frontend dashboard to manage and analyze an investment portfolio.

Important: This is a work in progress. Don't expect anything useful or fully functional yet.

• portfolio_assistant_front_end
  React + TypeScript dashboard for portfolio visualization and interaction.
  The frontend acts as the main entry point and consumes the portfolio, transactions, suggestions, logo, AI summary and financial news APIs.

• transactions-api
  Transaction-focused backend service. User transaction operations are sent here from the frontend, and those transactions act as the source of portfolio events.

• portfolio-api
  Main portfolio API built with Java 21, Quarkus, PostgreSQL and MCP support.
  It consumes transaction events to build and expose the current portfolio positions and state.

• suggestions_api
  Stock and financial instrument suggestion API with market data integration. Called directly from the frontend.

• logo_api
  Supporting service for stock/company logos. Called directly from the frontend.

• portfolio_summary_assistant
  Multi-agent portfolio analysis service using LangGraph, LangChain, FastAPI, SSE streaming and MCP tools. Called directly from the frontend to generate portfolio insights and summaries.

• financial-data-feed
  Financial news RAG system with RSS/API ingestion, hybrid search, Qdrant, Redis and MCP integration. Called directly from the frontend to provide portfolio-related news and market context.

A slightly cleaner diagram avoiding the duplicated visual edge to `transactions-api`:
