  As part of the cloud modeling team, I worked on building pipelines generating insights from real-time market data

  • Implemented highly flexible and scalable Realized Exposure Profile generator consuming market data from real-time Pulsar streams at 100s of messages/sec in Java using Apache Flink pipelines, publishing back protobufs to be consumed by downstream systems. Also configured a BigQuery loader to store the profiles in the data warehouse.

  • Built a Pulsar message replay system to consume data from BigQuery to generate backfilled profiles.

  • Generated Grafana dashboards to showcase real-time data for quick verification and analysis.

  I was the software developer in my team creating proof of concepts and working as part of a larger cross functional team in bringing innovative ideas to life.

  • Ideated, initiated, and followed through on creating an automation standardization platform, Codeshift, that scales across the organization, resulting in a 30% reduction in time to market and an uptick in uptime of hosted applications, while leading a team of 6 through sprint planning and feature development.

  • Developed an open source Terraform provider for the Firepower Management Center, resulting in policy management through code, utilized by enterprises with over 40,000 downloads.

  • Built an API first, microservice based migration engine, Skyport, to translate on-prem multi-branch firewall and proxy rulesets to an optimized ruleset for Cloud delivered Firewall and Cisco Umbrella, reducing manual workload by 33%.

  • Architectured and built "Lumos" for proof of value deployments using automation through infrastructure as code (IAC), reducing engineer time by 75%. The core was successfully reutilized in multiple engagements through its scalable API.

  • Conducted a multi-day training on Docker and Kubernetes for undergraduate students and fellow engineers.

• Technical Consulting Engineer, Cisco Systems

  Aug, 2019 - Mar, 20211 year 7 months

  In TAC, we provided industry-leading post-sales technical support worldwide for customers of medium to large scale networks. I was responsible for providing solutions to some of the most complex VoIP networks and SIP standard inter-ops with other service providers. I simultaneously worked on a multitude of internal projects with Python to create tools that automate tedious tasks involved in troubleshooting.

  • Diversified cross-product troubleshooting strengths to promote customer satisfaction, accelerate resolutions and minimize production delays. I worked towards elevated customer experience with best-in-class bug support, solution enhancements, and detailed documentation.

  • Built a multitude of internal projects to create tools that automate tedious tasks involved in troubleshooting such as VOS Diagnostics, Chat Bots for retrieving frequently accessed information, Remote controlled IP phones and HR Interview digitization system. Received Innovate and Create recognition for Collaboration for the same.

  • Gained and in-depth knowledge in the Apps domain and was a point of contact for colleagues in the team for a better understanding of SSO/SAML/OAuth2, SIP call flows across multiple products including Cisco Expressway with MRA and Instant Messaging and Presence.

  • Built a system for collecting feedback and managing remote interviews making virtual interviews go smoother in collaboration with the HR university recruiting team.

  • Developed a container orchestration platform from scratch on top of docker called 'Cisco Glass' for a cross-domain project with the security team to bring some standardization into the large amounts of innovative tools built by engineers and a way for customers to consume them without data security issues.

  • Volunteered for save the forest campaign by planting trees and fundraising events for the differently abled.

• Network Engineer Intern, Cisco Systems

  Jan, 2019 - Jun, 20195 months

  • Worked on "Multipoint Packet Analyzer" to collate and generate insights from packet captures collected from multiple points in a network by stitching them together.
