● Created AWS architecture spanned across 11 accounts for dev, qa, stage and production environments using AWS CloudFormation to provision VPC and resources like private and public subnets with their route tables, NAT Gateways, Internet Gateway● Provisioned Transit Gateway instead of VPC Peering as VPC peering was an older methodology used for connectivity between different VPCs and transit gateway is much more efficient in terms of connectivity and easier configuration● Used AWS Resource Access Manager for sharing resources like subnets and transit gateway from 1 account to other which is more efficient and cost saving● Used CloudFormation for provisioning other AWS architecture resources such as EKS, ECS Fargate, load balancers, RDS schemas, Private and Public Hosted Zones● Provisioned Jenkins as an ECS Fargate to create a serverless architecture with dynamic ECS slaves● Used advance level of Jenkins pipelines called Jenkins shared pipeline libraries which makes recursive usage of groovy functions and files to reduce duplicate Jenkins jobs and make it more templated● Created a solution for exposing only the bitbucket-hook endpoint from private ECS Jenkins publicly (without exposing the whole private Jenkins ECS Cluster) using nginx ECS service to receive webhooks from bitbucket cloud● Installed ArgoCD in Kubernetes cluster for continuously deploying and updating new deployments of dotnet core based microservices

Traccar Server Installation and Setup: Hetzner Cloud, Terraform, Docker Jenkins, Shell Scripting● The initial setup of Traccar Server was on Hetzner Cloud instance, which used to stop responding whenever there was a CPU load or Memory Crunch● Setup 2 Kubernetes Clusters, one for test environment and other for production environment in Hetzner Cloud using Terraform plugin kube-hetzner with modifications as per best practices and security standpoints● Implemented CICD process using Jenkins for frontend and backend builds for both test and production environment● Configured Kubernetes Dashboard, Prometheus and Grafana inside the clusters to monitor the performance of Kubernetes clustersExtra Contribution: Terraform, Github● Developed a feature for Terraform plugin kube-hetzner and contributed to the owner’s github repository for the plugin which was released in version v1.9.6: https://github.com/kube-hetzner/terraform-hcloud-kube-hetzner/releases/tag/v1.9.6

CSV Network Topology Data to MySQL DB Automation: Docker, Shell scripting, Python, Jenkins● Created a Microservice to fetch multiple CSV Network Topology files from the host server using shell script● Modified the shell scripts to also make the records of csv file unique to prevent MySQL DB Data insertion errors● Used Dockerfile and Docker compose file to create an image to be loaded automatically on Docker Swarm architecture via Jenkins● Modified the existing python files to convert that csv file fetched and patched into an inventory yaml file, which would get loaded into MySQL Database for each Network as soon as it gets generated in the directory● Since the Network files are generated every day, used cronjob to automate the running of shell scripts and make this whole process end-to-end automatedBug fix in Web Service: Java RESTful Framework, Maven, ReactJS, Remote Debugging (IntelliJ), Wildfly● Remotely debugged the Java RESTful microservice in IntelliJ and traced the root cause of the bug● Reverse Engineered the running module to find the working process of the code and without even knowing the full code, analyzed the fixes to be applied in the module with bug● After fixing backend, reverse engineered the frontend ReactJS code of the working module, and without knowing how to code in ReactJS, implemented the working module’s fixing part to non-working module to give meaning to the backend response of web service

Always seeking for peace with interest at my work. Skilled with various talents like learning at a good pace and good grasping power. I am one of the technology enthusiasts, who has hunger for new knowledge and learning new things which supports the "tech for a good future" moto. Apart from this, I do mimicry and voice dub of Shinchan Nohara and other actors. I also write parody songs and raps.

KX Healthcloud Kubernetes Cluster Implementation: AWS, kops, kubectl● Implemented 3 Kubernetes Clusters using kops for AWS, 1 for each dev environment, stage environment and production environment● Became expert in R&D involved in customizing the Kubernetes cluster in accordance with the best practices● Mastered ClusterRoles, ClusterRoleBinding along with Kubernetes API to create, update and patch the resources of Kubernetes using shell scripts involved in Jenkins● Implemented ConfigMaps and CronJobs together to achieve a special customization to make Kubernetes environment more stable Implementation of CICD via Jenkins: Jenkins, Shell Scripting, GitLab, JFrog Artifactory● Designed and developed the whole process of CICD to deploy the maven architecture-based Java spring boot microservices being developed and pushed into their GitLab repositories, to Kubernetes● Created shell script to automate the process of building the microservices, uploading to JFrog Artifactory and deploying to Kubernetes using Kubernetes API based shell script, on seeing a merge for a particular gitlab repository● Worked on Docker image to be used as a base image for Jenkins slave to get spin up as a Pod in the Kubernetes namespace and patch the previous deployments too

I am a DevOps Engineer trying to embrace my skills in Kubernetes environment as well as in Jenkins to deploy micro-services prepared in spring boot automatically in CICD process workflow.Always trying to find new ways to implement in Kubernetes by playing with Kubernetes API and combining it with Jenkins CICD flow, to achieve extraordinary automation techniques.

IOT Serverless APIs Deployment: AWS, Linux, Git, Jenkins, Serverless Framework● Designed and Developed a Code Pipeline in AWS, triggered on seeing Github commit webhook in a repository● Followed by CICD process, using AWS Code Build, convert the serverless framework file from the AWS S3 bucket into AWS Cloud Formation stack to deploy the API on the API Gateway● SoapUI testing script execution command is executed via Jenkins, which is integrated with AWS Code Pipeline as Testing step after deploymentIaaS to PaaS / SaaS Website Migration Assistant: AWS, Linux, Shell ScriptingDeveloped a shell script which would be placed in S3 Bucket, and AWS CodeBuild would use it to fetch the websites’ compressed code running in a traditional IaaS model and re-platform the website using AWS Elastic Beanstalk to run in a Cloud Native SaaS model

Created a small application that would store my extra time or due time for the previous day in office, for 1 week and send me notifications everyday at what time I can leave office.

B2B Webshop & Shipment Tracking Plugin Development: Linux, Symfony Framework, PHP● Designed and Developed a B2B Webshop which can be used to monitor and keep a track of products ordered by distributors from the Webshop itself● Developed PostNL integration plugin to track the orders, export orders and products, and import stock count and shipment information of the products
