It also utilizes databases such as Oracle and SQL Server. It has many upstream and downstream servers and uses MFT and SFTP for secure interaction. It uses tools like K2view for extracting data and Actuate for design-related tasks. This application also hosts few APIs to be accessible by Customers.

Responsibilities:

• Collaborated with business stakeholders to gather project requirements.
• Led development process, including General Design, High-Level Design, and Low-Level Design phases.
• Actively participated in coding, conducting unit testing, and performing integration testing.
• Improved systems with addition of new features and infrastructure.
• Investigated system issues and implemented resolutions to reduce downtime.
• Provided guidance and supervision to junior team members.
• Acted as mentor to help them develop their skills and knowledge.

Responsibilities:

• Provided quick and immediate solutions to critical issues that happens in live production environment.
• Onboarded APIs through APIGEE and ensured all security protocols are taken care of as per 42 crunch scan portals.
• Performed Code reviews for other developers and provided constructive feedback to ensure adherence to coding standards, maintainability, and readability.

Responsibilities :

• Owned multiple features, written code and unit tests, performed peer reviews to drive project success
• Developed software using C++ programming language, including designing and implementing complex algorithms and data structures
• Written and executed unit tests to ensure that code is free of defects
• Documentation and Version Control: Ensured to update release notes and user manual with details of all features being added in each release. Used version control tools such as Git to manage code changes and collaborate with other developers.

Project: CISCO Service Control Engine (SCE), vSCE.

Description: Cisco SCE is a network device which will control the real time Traffic between Client & Server and performs Stateful Deep-Packet Application Inspection. SCE's capabilities include - the ability to reconstruct Layer 4 traffic sessions built from multiple flows and packets, Application protocol awareness, Subscriber awareness, configurations through SCE API's. Cisco SCE is hosted on BareMetal while vSCE is hosted on Virtual machine.

Responsibilities:

• Implementing Inter process communication
• Packing the components on the build server and extracting them on the UCS setup
• Cloning image using Clonezilla and restoring
• Spawning Virtual machines using KVM hypervisor
• Building kernel for Virtual machine
• Modifying the kernel related information at run time
• Running the SCE image on the setup

Achievements:

I was recruited as a college hire for a software engineering role on the team, and quickly demonstrated my assertiveness, smart work, and adaptability, resulting in a promotion to Senior software Developer in 2012 and further to Lead Engineer in 2014.
