  • Set up and managed Selar’s BI system (Redash), built dashboards, and created analytical insights for products and business KPIs
  • Created a CI/CD pipeline for Schema Changes using GitHub action and Python Schema change library
  • Assisted Selar’s engineering team in optimizing database queries and tuning database performance.

Senior Data Engineer

Fido Money
05.2022 - Current
  • Authored and maintained three internal SDKs to allow other engineers to easily connect and interact with external applications like XCally (a contact centre platform), FreshSales & FreshDesk (both customer relationship management tools), and AWS services. These SDKs streamlined integration efforts, enabling faster and more efficient development when working with these external systems.
  • Designed and implemented cutting-edge data processing (ETL and ELT) pipelines, orchestrating the extraction of valuable data from over 10 diverse sources such as MongoDB, MySQL, Postgres, Mambu, Twilio, and Infobip. This data was seamlessly channelled to destinations such as Dynamo DB, S3 and Snowflake.
  • Operationalized and scaled multiple machine learning workloads in production using best MLOps practices. This involved the seamless deployment of ML pipelines, feature stores, ML model Training, ML inference, and more, employing tools like AWS SageMaker, FastAPI, Snowflake, and Kubernetes. These models serve as the core engine driving the business.
  • Crafted and developed Fido’s first A/B testing framework. This tool allowed data scientists and analysts to easily conduct experiments, reducing the setup time from two weeks to under 10 minutes. It automated data pipelines, infrastructure management, ML model inference and integration with third-party partners. Thanks to the experiments conducted with this tool, Non-Performing Loans (NPLs) decreased from 12% to 8%, resulting in a significant improvement in the organization’s financial performance.
  • Introduced, designed, and implemented robust streaming pipelines to process over 4M requests monthly with tools like API Gateway, Kinesis Stream/Firehose, S3, and Snowflake. Further Led the backend team in adapting architecture to handle high-volume data flows efficiently.
  • Created CI/CD pipelines to streamline data infrastructure and security across multiple accounts and automate data processes in production using GitHub Actions and AWS CloudFormation.
  • Ensuring that the data team is Adhering to development and data engineering best practices, including unit testing, coverage, data testing, IaaC, monitoring and alerts, and creating comprehensive engineering documentation.
  • Developed and maintained comprehensive documentation for infrastructure, MLOps and data processes, promoting knowledge sharing in the organization.
  • Empower and guide junior and mid-level engineers across the organization to reach their full potential.
  • Join forces with diverse, international teams of data scientists, analysts, engineers, and stakeholders to pioneer cutting-edge solutions through collaboration and innovation.
