Jul 2020 – Mar 2021 · 8 mos

• SME on cloud cost computation in Kubernetes.
• Implemented resource recommendations for right sizing of Kubernetes workloads to optimize spending.

Jun 2019 – Jun 2020 · 1 yr

• Founding member of Harness Cloud Cost Management (Saas for Cloud cost optimization) team, built the product from scratch and took to GA. We help enterprises to a keep tab on infrastructure cost expenditure, giving a summarised as well as power view of the underlying data and analytics.
• My work was initially owning the platform components for data collection of the required metrics and events, and later I worked primarily on computing cloud costs for Kubernetes clusters - computing costs, automatic cost attribution, mapping cost trend changes to cluster events, recommendations and optimization for applications deployed on the cluster.
• Skills: Java, Mongo, Kubernetes, AWS

Feb 2019 – May 2019 · 3 mos · Bengaluru, Karnataka, India · On-site

• Worked on the initial stages of a Real Time Payments system. The areas I've worked on include
• A message transformation module for inter-transformation of messages among various formats.
• POCs in Akka for architectural decision-making regarding the tech stack.

• Worked on the Visa developer platform. My primary area of ownership was implementing several features in an API gateway.
• Some of the areas I've worked on include
• Authentication mechanisms such as JWS/JWE, client certificates, HMAC-based auth etc.
• A performance testing toolkit (built in python) for running geo-distributed load tests. Given a test plan and a yaml config, it brought up EC2 instances in different regions, executed the tests, parsed logs at different layers to extract latency metrics, correlate time taken for each request across layers and create a report. This toolkit significantly brought down the iteration time for performance improvements in the gateway.
• Optimising the gateway for different kinds of scenarios, like preventing few slow backends from affecting traffic to other faster apis, reducing latency through concurrent execution of independent steps in the request processing flow, tuning http features like persistent connections & TLS session resumption.
• Message layer encryption for end to end confidentiality & integrity of the API payload.
• Took on the role of security champion, in which I liaised between the dev team and the Cybersec team. I helped triage and root-cause the issues flagged during security code review, and penetration testing.

• I worked on the Visa Developer Platform. VDP is a new initiative by Visa to present a unified facade to the different APIs provided by various teams in Visa.
• I was part of the platform team which works on API gateway and Identity and Access Management.
• My first project was around adding TLS mutual authentication to the gateway for which I was recognised with a go beyond award under the category (Excellence – Driving results, improving performance)

• The project was around optimizing the delivery of user uploaded videos in the Wooqer platform. The platform initially used flash for video delivery. We analyzed different video formats (flash vs mp4), various encodings for video/audio and different delivery mechanisms for video.
• Developed a script to decode/encode videos that auto-detected the optimum tuning parameters that could be used for achieving the right balance between bandwidth and quality.
