• Led the design and implementation of a standardized Python framework, incorporating reusable functions tailored for ETL activities. Developed adapters for diverse sources and targets, including cloud APIs, relational databases, Hadoop, and SAP. Additionally, facilitated compatibility with various file formats such as CSV, Parquet, and more.
• Devised a solution automating the deployment of the in-house developed centralized Python framework from the Git release branch to the PYPI Nexus repository. Utilized setup.py and Jenkins pipelines for streamlined and efficient processes.
• Crafted solutions in adherence to evergreen engineering principles, incorporating Continuous Integration/Continuous Deployment (CI/CD) pipelines for seamless deployment. Implemented virtual environments to containerize the solution, ensuring all necessary libraries are included via a requirement.txt file.
• Engineered a sophisticated integration solution tailored to project requirements, encompassing diverse sources and targets with necessary transformations. Accomplished this by creating a standardized modular Python function, ensuring reusability for future projects.
• Utilized Polars, Pandas, and DUCKDB to perform transformations within Python, demonstrating proficiency in data manipulation. Additionally, employed SQL procedures for transformations when deemed necessary, showcasing versatility in approach and skill set.
• Possess basic Oracle Hyperion skills essential for conducting integrations within the system, adapting to various sources or targets based on specific project demands.
• Adhered to Agile principles throughout the development process, spanning from defining the Definition of Ready (DoR) to the Definition of Done (DoD). Ensured the proper execution of Agile ceremonies, maximizing the benefits of an Agile approach in the development process.
• Employed innovative, out-of-the-box thinking to devise simple and efficient solutions for complex problems. Conducted Proof of Concepts (POCs) to validate and refine these solutions before their adoption.
• Identified avenues to enhance existing processes by incorporating cutting-edge tools and techniques. Spearheaded efforts to bolster pipeline security, implementing automated processes in alignment with industry standards and leveraging vaults for secure password management.
• Conveyed complex technical concepts to non-technical audiences with clear presentation style.
• Automated the end-to-end deployment process, spanning from development to production (live), utilizing Nolio and Jenkins. This involved packaging the solution, including all necessary libraries, into a specific virtual environment. This automation not only minimized human error but also ensured a seamless transition of solutions from lower to higher environments, mitigating potential infrastructure challenges.
