Experience
Authentication System for Openbank SA
I built an authentication engine in Go for a distributed microservices system. It can handle the scale of 1 million requests/second with a latency of 30 milliseconds. The entire infrastructure was created using Terraform. Kubernetes is used as the container orchestrator, Jaeger is used to trace the performance bottleneck, and Prometheus to monitor and set alarms.
CI/CD Setup for Monolith to Microservice Migration
https://nd.comAI/ML monolith platform migration. I led the DevOps migration from a Scala-based monolith platform to a microservice platform. Infrastructure was created using Terraform (Iac), Jenkins was used as the CI/CD tool, and Kubernetes was used for container orchestration. I suggested and implemented tools to manage configs and secrets, the IaC approach, and security best practices to be followed.
Infrastructure Setup for the Consulting Group
I set up the entire Infrastructure for one of Boston's most prominent consulting groups. I used best practices in CI/CD, Infrastructure as Code, distributed logging and tracing, observability, and monitoring for infra and application.
I analyzed and suggested pros and cons for the entire DevOps stack, implemented the right tool for each and effectively communicated with developers to set up seamless auto-deployment and one-click deployment for the apps.
Took sessions with the development team on the proper usage of tools for logging and monitoring.
