Data Pipelines & ETL Engineering

Stable, automated data flows – the foundation for KPIs, reporting & operations.

We build data pipelines that collect data from Leon, Jira and internal systems automatically, prepare it and write it into a model you can report on — with logging, error handling and measurable data quality rules to accept against.

Why data pipelines & ETL matter

Companies work with complex, often fragmented data sources: Jira, ERP, finance, Excel lists, manual exports — and Leon on top of that in flight operations.

This data is rarely consistent, clean or structured – and prevents precise reporting, stable decision paths and operational automation.

What comes out is a basis for dashboards, metrics and automation — loaded in time windows, guarded against concurrent runs and logged run by run.

What does ETL mean – and why is it decisive for operations?

ETL stands for Extract, Transform, Load – a core technical process that turns raw data from Leon, Jira and other systems into clean, consistent and analysable information.

ETL concept: extract, transform, load

Extract – Read data from source systems in a structured way

We extract data efficiently and incrementally from Leon, Jira or internal systems:

  • Quote Requests, Flight Requests, Legs, status changes
  • Events, master data, metadata
  • Change logs & histories

Extraction is performed via optimized GraphQL queries or APIs – efficient, stable, and without full imports.

Transform – Cleansing, Normalization & Mapping

During the transform phase, raw data is refined into a consistent, reliable, and production-ready foundation:

  • Deduplication
  • ISO-compliant date and time standardization
  • Mapping into a unified data model
  • State management and change tracking
  • Consolidation of distributed data points

The outcome: clean, structured data with clear relationships and enterprise-grade data quality.

Load - Loading into an optimized database structure

The final data is loaded into a high-performance SQL database or a central data warehouse:

  • Tables & Relations
  • Indexes for high query speed
  • Versioned data
  • Optimization for BI tools, Grafana & reporting

The four core components of your data pipeline

From data extraction to automated monitoring – every stage is designed to make your data clean, consistent, and reliably usable.

Data extraction via APIs / GraphQL / system access

We extract data from Leon, Jira and other systems in a structured and high-performance manner:

  • GraphQL queries for Leon
  • REST APIs & webhooks for Jira
  • internal databases, file systems, metadata

All data records are uniquely identified and prepared for further processing.

ETL, Mapping & Normalization

The data is automatically cleansed, validated, and transferred into a harmonized data model.

Highlights:

  • Separate paths for the initial load and the ongoing updates
  • Duplicate prevention & validation
  • Consistent state management
  • Historization & change tracking
  • Optimized data models for KPIs, reporting & finance

Loading into optimized databases

Structured data is written into a scalable SQL database – perfect for BI, dashboards, and automations.

Features:

  • Tables, relations, indexes
  • Performance tuning & partitioning
  • Fault-tolerant processing & logging
  • Fully automated pipeline runs (hourly/daily)

automation & Monitoring

We ensure that your data pipelines run reliably and continuously.

Services:

  • Scheduling through systemd or cron, with a lock against concurrent runs
  • Error handling and retries for failed runs
  • Monitoring of the runs and of the data quality rules
  • Automated tests of the processing rules
  • One log per run that makes the derivation traceable

Result: clean, available, and consistent data – at all times.

What each role gets out of it

Flight Ops

  • Reliable data foundation for dispatch and operations, refreshed at the agreed interval
  • Faster decision-making through clean, consolidated data
  • Automated data flows replacing manual exports
  • Stable, scalable processes powered by consistent leg, status, and event data

Sales & Charter

  • Transparent pipeline and conversion visibility
  • Faster response times driven by up-to-date KPIs
  • Data-driven forecasting and trend intelligence
  • Sales, operations and finance data in one model

Management

  • Company-wide “Single Source of Truth”
  • Reliable KPIs for Reporting, Finance & Strategy
  • The derivation of every metric traceable back to its source
  • Sound, data-driven decision-making capability

Put prepared data to work

Where prepared data turns into recurring cases, Jira Automation can take the next step once the interface has been agreed.

Working together and scope of services

We begin by defining which sources are connected, which data objects are needed from them and which target system they go into. This requires access to the sources or representative extracts, plus someone who knows what the fields mean in practice.

Initial load and ongoing updates are planned separately: the initial load is a one-off run across the existing data, updates then run at the agreed interval. Acceptance includes measurable data quality rules — which fields are mandatory, which values are valid, how exceptions are handled.

You receive the pipelines with logging and error handling, the data model in the target system and a description of the processing steps.

Not included: running the pipelines after acceptance, following up on changes to the source systems, and the licences of the source and target systems. If a vendor changes its interface, that is a new engagement — not a warranty case.
