Automotive Connected Fleet: Monolith to Cloud-Native Microservices Migration

Spearheaded the decoupling of a 15-year-old monolithic telematics and diagnostics core into high-throughput, event-driven Spring Boot microservices on Kubernetes.

• Architectural Implementation:

Modernized legacy Oracle backend to CockroachDB & TimescaleDB, supporting 2.5M+ active connected vehicles.
Implemented Apache Kafka pipelines processing 45,000 telemetry messages/sec with end-to-end P99 latency under 35ms.
Architected a zero-downtime Blue/Green deployment strategy across AWS (EKS) and private multi-region OpenShift clusters.
Enforced strict ISO 26262 functional safety and UNECE R155 automotive cybersecurity compliance across all telematics ingress nodes.

Enterprise Model Context Protocol (MCP) Server Infrastructure for Multi-Agent AI

Architected and deployed enterprise-grade Model Context Protocol (MCP) servers enabling secure, bi-directional tool execution between LLM agents (Claude, GPT, Ollama) and internal engineering backends.

• Architectural Implementation:

Engineered JSON-RPC 2.0 transport layers over stdio and SSE with strict mutual TLS (mTLS) and token authentication.
Integrated semantic vector indexing (Qdrant & pgvector) allowing autonomous agents to query Jira, Confluence, and internal Git repositories.
Reduced repetitive DevOps incident remediation cycle time by 42% via self-healing multi-agent diagnostic runbooks.
Established sandboxed code execution environments preventing untrusted LLM prompt injection and unauthorized API lateral traversal.

High-Throughput SEPA Payment Gateway & Clearing Engine Modernization

Led architecture modernization for a Tier-1 German banking group, transitioning legacy batch clearing jobs to real-time ISO 20022 message processing.

• Architectural Implementation:

Designed an idempotent event-sourcing transactional ledger with event replay capabilities using Kafka and PostgreSQL.
Engineered resilient circuit breakers and rate limiters compliant with BaFin audit standards and PSD2 regulation.
Achieved 99.999% availability during peak transaction clearing windows (over €180M processed daily).
Cut transaction latency from batch windows down to sub-800ms real-time settlement.
