Backend Developer with 2.5 years of professional experience building production systems — from IoT device management platforms to e-learning APIs with semantic search powered by AI.
I've worked in agile environments (Scrum) across the full development cycle — from architecture design to production deployment.

• 💡 Passionate about clean and well-defined architectures — DDD, Hexagonal (Ports & Adapters), CQRS and event-driven systems.
• 🤖 Experienced in building RAG pipelines and LLM integrations in production (pgvector, LangChain, Ollama, OpenAI).
• 🔭 Focused on code maintainability, testability, and delivering real business impact.
• 🌱 Continuously learning — currently deepening distributed systems and AI engineering.
• 💬 Open to new opportunities, collaborations, or just a good tech chat.

• Hexagonal Architecture (Ports & Adapters) — domain fully decoupled from infrastructure
• Domain-Driven Design (DDD) — bounded contexts, aggregates, value objects, domain events
• CQRS + Event-Driven — async event bus with RabbitMQ, command/query separation
• RAG Pipelines — embeddings, vector search (pgvector), LLM response generation
• Layered separation, SOLID principles, and clearly defined responsibilities

Backend for medical device management. TypeScript/Express with full Hexagonal + DDD architecture, CQRS, RabbitMQ event bus, and CI/CD on AWS ECS via Azure DevOps.

Laravel API with a complete RAG/SmartSearch system: pgvector embeddings, swappable Ollama/OpenAI strategy pattern, async embedding jobs, Redis cache.

Multi-role marketplace backend with real-time chat (Socket.IO), dual payments (Stripe + Mercado Pago), geospatial search (PostGIS) and push notifications (Firebase).

Intelligent avatar powered by a WebSocket → Whisper STT → Ollama LLM → Piper TTS pipeline. 5 microservices orchestrated by FastAPI, XState state machines mirrored on both ends.

At Alaska Tech we build digital products for real clients — focused on technical quality and business impact.
