What do you do if you're a data engineering intern trying to master the best tools and technologies?
Data engineering is a fast-growing and dynamic field that requires a combination of technical skills, business acumen, and creativity. As a data engineering intern, you might be wondering how to make the most of your opportunity and learn the best tools and technologies for your career. In this article, we will share some tips and advice on how to succeed as a data engineering intern and master the essential skills and tools you need.
Before you dive into the data, you need to understand the business problem you are trying to solve and the value you are creating. Data engineering is not just about building pipelines and platforms, but also about delivering insights and solutions that align with the business goals and needs. As an intern, you should ask questions, do research, and communicate with your stakeholders and mentors to understand the context and scope of your project and how it fits into the bigger picture.

It's all about the use cases. We need to understand the data organization layers. What are the functional needs of each layer, starting from ingestion, data lake, data warehouse, and data mart? Data types - structured data, semi-structured, unstructured. Demand of data - milliseconds, minutes to hour. Data catalogs, ETL tools, and reporting needs. We identify tools based on the functional need. I am storing events from the Contact Center in Timestream while building a columnar data warehouse in Redshift. For all sources use Lake Formation. Building catalog using Glue, querying using Athena and Spectrum. For call journey using Neptune Graph DB. Searching documents using ElasticSearch. Using DynamoDB and MongoDB for key/value and JSON.
Data engineering involves managing the data lifecycle, from ingestion to analysis to visualization. As an intern, you should learn how to work with different types of data, such as structured, unstructured, streaming, or batch, and how to use the appropriate tools and methods for each stage. For example, you might use SQL, Python, or Spark to extract, transform, and load (ETL) data from various sources, such as databases, APIs, or files. You might also use cloud services, such as AWS, GCP, or Azure, to store, process, and scale your data. You might also use tools like Airflow, Luigi, or Dagster to orchestrate and monitor your workflows and pipelines.

✅Data is an “asset” for most of the modern companies which are trying to be a data-driven company. When I say asset, it means every piece of data should have owner, its own business context and a proper life cycle. In big data world, there are lot if solutions frameworks and architectures are already built and widely used in industry (such as Lambda or Kappa architecture). Intern should try to get grasp of those patterns. Along with that he should pick any latest tool in market and learn the implementation part. Lastly, stay updated via social media, webinars, conferences etc.
One of the exciting aspects of data engineering is that there are always new and emerging technologies and frameworks to explore and learn. As an intern, you should take advantage of the opportunity to experiment with different technologies and see how they can improve your performance, efficiency, or quality. For example, you might try using Kafka, Flink, or Beam for streaming data processing, or Databricks, Snowflake, or BigQuery for data warehousing and analytics. You might also use tools like Docker, Kubernetes, or Terraform for containerization and infrastructure as code.
Data engineering is not only about writing code, but also about ensuring that your code is reliable, maintainable, and reusable. As an intern, you should document and test your code to make it easier for yourself and others to understand, debug, and improve. You should use tools like Git, GitHub, or Bitbucket for version control and collaboration, and tools like PyTest, unittest, or nose for testing your code. You should also follow the best practices and standards for coding style, naming conventions, and documentation.
Data engineering is a complex and evolving field that requires constant learning and improvement. As an intern, you should seek feedback and mentorship from your peers, managers, and mentors to enhance your skills and knowledge. You should be open to constructive criticism, learn from your mistakes, and ask for help when you need it. You should also network with other data engineers, join communities and forums, and follow blogs and podcasts to stay updated and inspired.
Data engineering is also about demonstrating your value and impact to the business and the industry. As an intern, you should showcase your work and achievements to your stakeholders, managers, and potential employers. You should use tools like Tableau, Power BI, or Dash to create dashboards and reports that visualize your data and insights. You should also use tools like Medium, LinkedIn, or GitHub Pages to create a portfolio or blog that showcases your projects, code, and learnings. You should also highlight your skills, certifications, and awards on your resume and profile.

As an intern, "master" would be a strong word. I would say be familiarized first and understand the underlying principles and fundamental concepts. From there, it would be more easier to understand the complex once.
