Experience

Duo World

https://www.duoworld.com/

Duo World is a PaaS-based project I worked on for app developers to develop applications using JavaScript and Node.js to host it in the cloud without worrying about servers and hosting. Supports multiple tenancies, particularly data storage that uses caching, data load balancing, distributed configuration handling, and easy scaling.

Tasks being performed: development, implementation, and maintenance

Technologies used: Go Language, MySQL, MSSQLCE, PostgreSQL, Mongo DB, Docker, Kubernetes, Google Developer Console, and Jenkins.

Lumity

This startup in Silicon Valley provides employers with tools that optimize health care costs and simplifies the approach to picking a healthcare plan for their employees. I worked on this project as a senior DevOps engineer and maintained a Kubernetes cluster for different app environments. I also handled building and executing various deployments using Jenkins declarative pipelines. We maintained a Sonatype Nexus repository as a private artifact registry, and logging and monitoring using SumoLogic. Prometheus was used as a monitoring tool in the Kubernetes cluster.

Surround Insurance

Surround is a traditional insurance product company striving to serve new consumers. I was tasked with being a senior DevOps engineer and maintaining AWS infrastructure using ECS, AWS Fargate, and Jenkins.

Pixglo

Modern video advertisers face unique and enormous problems in connecting brands with engaged consumers. Content creators, media platform owners, and brand advertisers need new ways to cut through the clutter and engage viewers. The answer is not even more intrusive advertising or un-targeted placements and sponsorship. The data clearly shows this does not work. Pixglo's breakthrough platform offers a new genre of digital advertising technology that leverages AI to place the visual elements of a brand inside a video, post-production, as if there during the time of filming. Pixglo's technology platform makes video advertising more relevant and non-intrusive for viewers, profitable for media rights owners, and effective for advertisers. Pixglo was selected as an NVIDIA inception member, a program for incorporated startups that are driving advances in the fields of artificial intelligence (AI), data science, and machine learning.

I was mainly handling full infrastructure from scratch, CI/CD, monitoring, backup, and disaster recovery.

Make robots easy to use instantly to add world-class usability to hundreds of robots from the biggest brands. Heavy payload industrial robots are as user-friendly as collaborative robots with the operating system. I mainly handled the complete Infrastructure from scratch, CI/CD, monitoring, backup, and disaster recovery.

Content Hub - Acquia

https://docs.acquia.com/contenthub/

Acquia Content Hub is a cloud-based content distribution and discovery service. Customers can use this service to author, search, and share content in a complex network of sites and channels. Whether it includes multiple sites, diverse departments, or different technologies, Content Hub syndicates content and configuration at scale and enables global enterprises to discover, reuse, and distribute content throughout their entire organization in a secure cloud environment. Content Hub syndicates content between your fleet of Drupal sites with configuration parity. I mainly handled full infrastructure from scratch, CI/CD, monitoring, backup, and disaster recovery.
