What I Do

Core Expertise

AI Platform Architecture

Designing and implementing production-grade AI platforms with autonomous agents, RAG, and multi-model orchestration. Hexagonal architecture with domain-driven design for maintainability and scalability.

Cloud-Native Solutions

Building scalable, resilient systems on AWS with Infrastructure as Code, event-driven microservices, and comprehensive observability. Expertise in EKS, Bedrock, S3, and serverless architectures.

Enterprise Development

20+ years delivering mission-critical systems for banking and finance. Deep expertise in Spring Boot, Kafka, PostgreSQL, and building secure, compliant applications that handle millions of transactions daily.

Technical Leadership

Leading architecture decisions, mentoring teams, and bridging business requirements with technical solutions. Certified iSAQB architect with proven track record in complex enterprise environments.

Featured Work

Enterprise AI Platform Case Study

Production-grade AI platform with autonomous agents, RAG, and enterprise security

A comprehensive enterprise AI platform built with Spring Boot, AWS Bedrock, and event-driven microservices. Demonstrates mastery of hexagonal architecture, domain-driven design, and production-ready AI implementation.

9 Production Microservices

Hexagonal architecture with Domain-Driven Design. Each service with dedicated PostgreSQL database, implementing bounded contexts and eventual consistency.

Autonomous Agent Orchestration

LangGraph4j-based execution engine with checkpoint recovery, human-in-the-loop workflows, and real-time cost tracking across multiple LLM providers.

RAG with pgvector

Semantic search using PostgreSQL pgvector extension with 1536-dimensional embeddings, HNSW indexing, and optimized retrieval pipeline for enterprise knowledge bases.

Enterprise Security & Compliance

JWT authentication, RBAC with 30+ permissions, content moderation, PII detection, and compliance-ready architecture (SOC 2, ISO 27001, GDPR, OWASP).

Real-Time Analytics

Kafka event streaming with pre-computed aggregations, distributed tracing with Jaeger, Prometheus metrics, and comprehensive observability stack.

Infrastructure as Code

Complete AWS deployment with Terraform, Kubernetes orchestration, Docker containerization, and CI/CD pipelines with GitHub Actions.

OpenTelemetry

Hexagonal Architecture

Domain logic isolated from infrastructure concerns. Pure domain models with ports & adapters pattern for maximum testability and maintainability.

Event-Driven Communication

Kafka topics for async messaging. Event sourcing for audit trail. DLQ for poison pill handling and reliable message processing.

Database Per Service

Each microservice owns its PostgreSQL database. No shared databases. Eventual consistency via events ensures loose coupling.

Über Mich

Erfahrung trifft Innovation

20+ Jahre Enterprise-Architektur. Jetzt an der Spitze der Generative AI Revolution.

Hi, ich bin Nady Habashy – Senior Software Architect, AWS Solution Architect und AI Engineer mit über 20 Jahren Erfahrung in der Entwicklung skalierbarer Enterprise-Systeme.

Meine Karriere begann mit komplexen Java-Enterprise-Architekturen für führende Finanzinstitute wie LBBW, ING-DiBa und Südleasing. Dort entwickelte ich hochperformante Compliance-, Risiko- und Payment-Systeme, die heute täglich Millionen von Transaktionen verarbeiten.

In den letzten Jahren habe ich mich auf Cloud-Native Architekturen und Generative AI spezialisiert. Heute konzipiere und entwickle ich produktionsreife AI-Plattformen auf AWS – mit Spring Boot, Spring AI, Amazon Bedrock und modernsten LLM-Technologien.

Was mich auszeichnet? Die Kombination aus tiefer Enterprise-Erfahrung und modernsten AI-Technologien. Ich verstehe nicht nur, wie man innovative AI-Lösungen baut – sondern auch, wie man sie sicher, skalierbar und compliance-konform in bestehende Unternehmenslandschaften integriert.
