Complex challenges. Engineered solutions.

A single switch is straightforward. At multi-device scale, unique device identity, consistent communication, predictable switching states and firmware maintenance become the real engineering challenge.

Microcontroller firmware and control logic were adapted around structured device parameters, local MQTT connectivity, defined relay states and an architecture for future firmware updates.

An adaptable embedded foundation that makes connected switching solutions easier to configure, test and integrate into broader control systems.

A measurement is useful only when data acquisition is reliable, transmission is structured and changing conditions can be understood across devices.

Connected sensor-node concepts and prototypes were developed using ESP32-based components, local communication and structured telemetry for monitoring interfaces.

A modular prototype foundation in which acquisition, communication and analysis are treated as one engineering system.

Large datasets offer little value if recurring failure patterns, anomalies and gradual measurement drift remain hidden in unstructured raw records.

The concept combines consistent record identification, focused filters, failure-pattern analysis, trend charts and condensed performance indicators in one coherent workflow.

A clearly defined analysis concept showing how technical results can be interpreted and emerging anomalies surfaced. Not an approved client reference.

Complex workflows often break down around unclear ownership, duplicate entries and missing traceability. Off-the-shelf software rarely fits every operational exception.

Development of tailored web and desktop tools with role-based views, structured records, status tracking, barcode workflows and focused reporting/export functions.

Practical software building blocks that make demanding workflows easier to record, manage and analyse—without exposing internal organisations or user data.

Critical conditions are not always obvious. Small differences and varying circumstances can make an apparently simple check unreliable.

The problem was broken down into verifiable questions. Relevant influencing factors were translated into a structured method for condition assessment and plausibility checks.

A traceable technical verification strategy based on defined criteria rather than assumptions.

Large datasets may conceal recurring anomalies and gradual changes. Manual examination makes it difficult to spot patterns across extended periods.

Software was developed with focused filters, comparative analysis, trend views over time and structured reports. This supports targeted investigation of changing behaviour.

A working analytics tool that organises technical data and supports trend investigations, without making unverified savings or predictive accuracy claims.
