Senior Engineer (Python)

Confidential

Responsibilities:

• Developed Architecture for Parsing the various kinds of log files and extract information using Regular expressions.
• Developed a Template-Driven Parser to extract information from different kinds of log files. The template drives the Parser by providing the search criteria such as Regular expressions and rules to extract information.
• Created complex Regular expressions to extract information from log files.
• Creating UI/UX designs and development of an Angular JS application to build complex Regular Expressions.
• Development of an Angular JS application to show Cassandra DB cluster’s Key Spaces and Table Schemas information by rendering it from JSON.
• Built RESTful services to Write large files (used SFTP protocol) into Cassandra database using Apollo Framework (Cisco’s legacy framework).
• Implemented web services on the top of Web.py, Apache ModWSGI frameworks to perform REST methods to query Cassandra, MSSQL databases.
• Design and Development of an Angular JS application show Cassandra DB key spaces and Table schemas.
• Worked on Angular JS application enhancements to create dynamic UI for visualizing the data fetched from Database.
• Writing Ansible Playbooks for Application deployments automation in supporting the Continuous Integration/Continuous Development.

Environment: Python, Angular JS, Re (python module), SFTP, Web.py, ModWSGI, Cassandra, MSSQL.
