About Me
Entrepreneurial Cloud Data Engineer with over 5 years experience in different data roles across many different industries.
I am responsible for making sure companies start their data journey with confidence, leveraging the cloud to make good data management a reality instead of a ‘nice to have’.
I am pretty hands on, skilled in SQL, Python, Cloud computing and Git to interact with data and build scalable data products.
Work & Experience
Cloud Data Engineer
The Six Eyes IT Solutions
● Defined the data roadmap for the EdTech startup, working with the founder to implement proper use of CRM and SIS tools for data management. This included building API integrations, managing data models and migrating data to AWS cloud for storage within a Redshift warehouse. ● Developed an OpenAI backed chat bot. The integrated web application widget used Django as its framework and was trained using a curated knowledge base from the company. This bot was deployed as a virtual assistant for students to help them in the event of a human instructor not being present.
Cloud Data Engineer
Vodafone
Automated the previously manual BI suite of mobile network data in Vodafone, using cloud migration to create a new production data lake. This involved sanitisation of raw files coming out from source data by SFTP file transfers and ingesting them into S3. Ran transformations on these CSV/JSON files in AWS Glue, using PySpark. This solution captured the hourly changing behaviour of 280,000 radio cells across the UK using very complex business logic
