Data engineering

Your data is there. Let’s make it work for you.

We connect information sources, automate data processing and build systems to store, organise and use it. From a single integration to a complete data platform.

  • Connected data
  • Automated processes
  • Information ready to use

What we can build

From different sources to data you can use.

We build systems that connect, process and organise information so your applications, teams and tools can work with it.

Data integration

We connect databases, APIs, files and applications to bring information together from different sources.

Data pipelines

We automate data extraction, transformation and loading to avoid repetitive manual processes.

Databases and storage

We design and optimise systems for storing, querying and managing information.

Data warehouses and data lakes

We build environments to centralise large volumes of data and make it easier to query and process.

Data quality and validation

We detect inconsistencies, duplicates and errors, and add checks to improve the reliability of information.

Real-time and batch processing

We prepare flows that process information periodically or as it is generated, according to your project’s needs.

What you gain

Less time preparing data. More time using it.

  1. Less manual work

    Automate information imports, cleaning and updates.

  2. More reliable data

    Reduce errors and inconsistencies with validation processes and quality checks.

  3. Connected information

    Bring data together from different tools without having to consult each one separately.

Unify data from different applications to work with a shared source of information.

ETL · Automation

File processing

Import, transform and validate files automatically, without repeating the same manual work.

Data · Analytics

Information for reports

Prepare and update the data that dashboards, indicators and analytics tools need.

Data pipelines · AI

Data for Machine Learning

Build processes to prepare and maintain the datasets used by AI models.

Why Valendra

Data needs more than somewhere to be stored.

We combine data engineering, software development and infrastructure to build systems that work from end to end, from connecting sources to using information in production.

  1. End-to-end engineering

    We treat data extraction, transformation, storage and distribution as parts of the same system.

  2. Development and integrations

    We can build the APIs, services and applications that need to consume or exchange information.

  3. Infrastructure and operations

    We also understand the environments where data processes run and how to keep them operating.

  4. AI and Machine Learning experience

    We understand how to prepare data for model training, inference and intelligent applications.

How we work

First we understand your data. Then we build the solution.

Every project starts with different sources, formats and needs. We study how information is generated and used before designing the processes it requires.

  1. Analyse the sources

    We review where data comes from, its formats, quality and update frequency.

  2. Design the flow

    We define how to connect, transform, validate and store information.

  3. Build and test

    We build the processes and test them with representative data.

  4. Integrate and deploy

    We connect the systems and put the processes into operation.

  5. Maintain and improve

    We can monitor flows, fix issues and adapt them to new requirements.

Frequently asked questions

Your data, clearly explained.

What is data engineering and what is it used for?

Data engineering connects, transforms, validates, stores and distributes information so it can be used in applications, reports or artificial intelligence projects. It replaces manual tasks with repeatable processes and makes data available according to the project’s needs.

What does a custom data engineering service include?

It may include source analysis, integrations, ETL or ELT pipelines, database design, storage and data quality checks. We can also deploy and maintain the processes. Tasks, deliverables and support are defined around your needs, without requiring a complete data platform.

Do my data sources need to be organised before we start?

No. We can start by reviewing the sources, formats and processes you already use. We identify access, quality or update issues and prioritise the work to help you use the information available.

Can you connect existing applications, APIs and databases?

Yes, provided the systems allow the required access. We review APIs, permissions, formats and source limits to design the integrations. We can connect internal applications, external services, databases and files without replacing all your tools.

What is a data pipeline and when do I need one?

A pipeline is a sequence of processes that moves and prepares data from its sources to a destination. It can help if you regularly import files, combine information from different applications or update data manually. We define frequency, transformations and checks around the intended use.

What is the difference between ETL and ELT?

In ETL, data is extracted, transformed and then loaded into its destination. In ELT, it is extracted and loaded first, then transformed in the destination environment. The choice depends on sources, volume, storage and processing requirements; we review your situation before proposing an approach.

Can you automate imports of Excel, CSV or JSON files?

Yes. We can build processes to import, transform and validate files automatically. We review their structure, how they arrive, how often they change and what should happen when fields are missing or errors occur. The flow can include logs and notifications to support tracking.

Do I need a data warehouse, a data lake or a database?

It depends on how you want to use the information. A database may be enough for a specific application or integration. A data warehouse organises data for analytical queries; a data lake can store information in different formats. We assess your sources, queries and volume before recommending an architecture.

Can you prepare data for dashboards, reports and BI tools?

Yes. We build processes to collect, transform and update the data used by your analytics tools. We agree on indicator definitions, quality checks and update frequency so reports use consistent information.

How do you improve data quality and detect errors?

We define checks for formats, required fields, duplicates, ranges and relationships between data. We can add logs and alerts to detect issues and support review. Checks and error handling are agreed according to the project’s requirements.

Do you work with real-time data and batch processing?

Yes. We can design periodic processes or flows that process information as it is generated. We choose the approach around the required update frequency, volume, sources and operating cost. Not every project needs real-time processing.

Can you improve existing pipelines or databases without starting over?

Yes. We can review existing processes, fix errors, optimise queries or add quality checks. We can also modernise parts of the system gradually. Work can focus on a single integration or process without building a new platform.

Can you prepare our data for artificial intelligence and Machine Learning?

Yes. We can build extraction, transformation and validation processes to prepare and update the datasets used by AI models and applications. We define formats, quality rules and update frequency with the team that uses the information.

How do you manage access to data sources?

We review which systems and data each process needs with you. We agree on permissions and credential handling, aiming to limit access to the tasks required. Security requirements and responsibilities are defined around the project environment.

How much does a data engineering project cost?

The quote depends on sources, integrations, volume, transformations and update frequency, as well as deployment and maintenance needs. We can work hourly, with a monthly allocation or on a fixed-scope project. Financial terms and scope are agreed before we start.

Do you also maintain data pipelines?

We can maintain and improve the processes we build, monitor their operation and adapt them when sources or requirements change. Scope, response times and included tasks are agreed around the project. 24/7 support with an SLA is contracted and priced separately.
