Technical Projects

Project 01

Private Ethereum Proof-of-Stake Blockchain with Blockscout

Designed and deployed a fully private Ethereum Proof-of-Stake (PoS) blockchain network with a custom chain ID. The infrastructure includes a Dockerized execution layer, consensus layer, validator client, and a complete Blockscout explorer stack for on-chain visibility.

Built a private Ethereum PoS network with a custom chain ID
Deployed Go-Ethereum (Geth) as the execution client
Configured Beacon node and Validator client for PoS consensus
Set up own validator wallet to collect transaction fees
Integrated Blockscout frontend and backend for block, transaction, and account exploration
Containerized all services using Docker and Docker Compose
Managed inter-container communication through Docker networking
Verified block finalization, validator participation, and fee distribution

Docker Go-Ethereum (Geth) Beacon Node Validator Blockscout PostgreSQL Redis Linux

Project 02

CI/CD Pipeline using CircleCI for Web2 Application (GCP)

Implemented a fully automated CI/CD pipeline using CircleCI to build and deploy a Web2 domain-selling platform that provides Web3 services. The application is deployed on a GCP Virtual Machine using SSH-based deployment with Nginx as a reverse proxy.

Configured CircleCI pipeline using .circleci/config.yml
Wrote Dockerfile to containerize the application
Automated build and deployment triggered on every Git commit
Implemented SSH-based deployment directly into GCP VM from the pipeline
Deployed and configured Nginx container as a reverse proxy by connecting both the application in same docker network
Eliminated manual deployment steps through full pipeline automation
Ensured zero-touch deployment workflow for faster releases

Docker CircleCI Nginx GCP VM Linux Git

Project 03

Advanced CI/CD Automation using Jenkins (Multi-Branch Pipeline)

Designed and implemented a Jenkins-based CI/CD system running as a Docker container on a GCP VM. Built a multi-branch pipeline strategy to handle automated build and deployment workflows for development, production, and release branches.

Deployed Jenkins as a Docker container on GCP VM
Created multi-branch pipeline for dev, prod, and release branches
Implemented branch-specific Docker build and deployment logic
Automated dev → prod → release promotion workflow
dev job directly builds and deploys dev container
release follows the same controlled promotion process like prod
Wrote shell scripts for consistent build and deployment across branches
Configured Apache web server container to serve the application as reverse proxy & Connected via docker network
Ensured clean, repeatable, and controlled release cycles

Docker Jenkins Shell Scripting Git GCP VM Linux APACHE

Project 04

Infrastructure Monitoring & Alerting with Prometheus, Grafana & Odoo Integration

Designed a centralized monitoring and alerting system for both local servers and cloud VMs using Prometheus, Grafana, Alertmanager, and custom alert hooks. Integrated alerts directly into Odoo CRM channels using RPC/JSON communication.

Deployed Prometheus, Grafana, Alertmanager, Alert-Hook, Node Exporter, and cAdvisor
Built a custom Docker image for Odoo CRM from source code
Connected all monitoring and application containers using a same Docker network
Monitor the CPU, RAM, Disk usage of the server
Container-level metrics via cAdvisor
Cloud VM metrics using Node Exporter
Configured Prometheus targets using IP-based aliases
Configured Apache web server container to serve the application as reverse proxy & Connected via docker network
Implemented custom alert hooks to send real-time alerts to Odoo channels
Alerts triggered automatically when local server or cloud VM resource usage crosses thresholds
Enabled centralized visibility and proactive infrastructure monitoring
