Senior full-stack engineer with 9+ years building distributed systems, cloud-native backends, and industrial IoT platforms across enterprise and product environments.

Currently at HOPPECKE Batteries (Germany) — engineering end-to-end IoT monitoring solutions that bridge ESP32 edge hardware, MQTT telemetry pipelines, GCP Cloud Run microservices, and SAP ERP systems.

Previously at Northstar Technologies (7 years) — led engineering teams, architected high-availability infrastructure, and drove a full enterprise platform migration (Liferay 6.2 → 7.2) serving multiple clients.

What I build:     Microservices · Cloud-native backends · IoT pipelines · Enterprise ERP integration
How I build it:   Clean architecture · OWASP security hardening · CI/CD automation · production observability
Where I build it: Germany 🇩🇪 — on-site, hybrid, or remote

Data & Integration

Java · Spring Boot · GCP Cloud Run · Cloud SQL · MQTT · ESP32 · SAP ERP · React / TypeScript · Docker · GitHub Actions

End-to-end IoT monitoring system for industrial battery fleets at HOPPECKE Batteries. ESP32 edge sensors publish telemetry over MQTT → ingested by Spring Boot microservices on GCP Cloud Run → persisted in Cloud SQL → surfaced in a real-time React/TypeScript dashboard → synced bidirectionally with SAP ERP.

Problem solved: Replaced manual battery health checks with continuous anomaly detection, cutting operational response time from hours to minutes and eliminating unplanned downtime across the fleet.

Java · Spring Boot · Camunda BPMN · REST API

BPMN-driven process automation integrated with Spring Boot. Covers process deployment, lifecycle task management, and REST API exposure for workflow orchestration — mirroring patterns used in enterprise ERP and financial systems.

Problem solved: Decouples business process logic from application code, making complex workflows auditable, versioned, and modifiable without redeployment.

Java · Spring Boot · PostgreSQL · REST

Production-style REST API for delivery and payment operations. Implements clean layered architecture, DTO mapping, and transactional consistency — built as a reference for enterprise-grade Spring Boot service design.

Problem solved: Provides a reusable, maintainable service template that handles the transactional complexity of coordinating delivery state with payment processing.

Java · Spring Boot · Docker

Multi-service Spring Boot architecture demonstrating independent deployability, inter-service communication, and Docker-based service composition. A working reference for teams migrating from monolith to microservices.

Problem solved: Gives teams a concrete starting point for microservices decomposition — showing the seam between services before over-engineering with a service mesh.
