Case Examples

Projects with clear operational impact

The focus is on stable interfaces, traceable processes, and planned evolution of existing systems.

Selected Projects

ERP Integration via Lobster Data

Connecting heterogeneous systems through standardized mapping and routing flows.

ProblemInconsistent structures between ERP and platform caused unreliable transfers.

SolutionIntroduced strict mapping rules, field validation, and structured error handling in the integration flow.

ResultMore stable data exchange, faster root-cause analysis, and fewer manual corrections.

ImpactThe operational flow became more resilient and required significantly fewer manual interventions.

Data Processing for Downstream Systems

Python- and SQL-based preparation of heterogeneous data sources.

ProblemSource format differences produced inconsistent records in dependent systems.

SolutionImplemented transformation logic with checks for completeness, data types, and mandatory fields.

ResultCleaner data quality, fewer correction loops, and more reliable downstream processing.

ImpactBusiness teams could rely on more consistent records and spot process deviations earlier.

Automation of Repetitive Operational Tasks

Containerized script execution and standardized operational procedures.

ProblemRepetitive manual work consumed time and increased operational error risk.

SolutionContainerized script workflows, centralized configuration, and repeatable run rules.

ResultPredictable execution, reduced error rates, and shorter processing times.

ImpactRoutine operations became more predictable and team capacity shifted to higher-value work.

Monitoring and Interface Incident Analysis

Structured logs, prioritized alerts, and traceable failure paths.

ProblemInterface failures were detected late and troubleshooting cycles were too long.

SolutionImplemented unified logging, alert priorities, and clear escalation procedures.

ResultEarlier detection, faster diagnosis, and noticeably shorter outage windows.

ImpactIncidents became more transparent to handle and escalation was processed in a more structured way.

Additional Project Experience

Operationally Stable Mapping Flows with Lobster Data

Rule-based data flows with clear error classes and traceable correction paths.

Data Migration During System Transition

Legacy data cleanup and reliable mapping into the target system.

Standardized Import and Export Pipelines

Unified file standards with pre-processing validation gates.

Self-hosted Server Infrastructure

Containerized services, reverse proxy, and automated backups.

Central Device Management System

Custom-built MDM solution for heterogeneous device environments.

Modernization of a Long-Grown Web Application

Structured evolution of a PHP/MySQL system that had grown over many years.

Interactive Real-Time Map View

Leaflet-based live map display with automatic refresh.
