and OpenShift for scalable infrastructure, backed by PostgreSQL, MongoDB, Redis, and Kafka for event-driven

communication.

• Reduced production defects by 30% and achieved a 100% sprint delivery rate over 8 sprints with zero story carryover, through

Agile/Scrum practices, rigorous code reviews, and continuous improvement driven by CI/CD tools like GitHub Actions and

Jenkins.

• Processed and validated high-volume Shopify datasets using Postman, Salesforce Workbench, Shell scripting, and data

pipelines involving relational databases, enhancing catalog, inventory, and order sync across distributed systems.

• Monitored and optimized end-to-end system performance using Prometheus, Grafana, and ELK Stack, enabling proactive

alerting, incident response, and MTTR reduction by over 40%, while leveraging cloud computing tools for real-time

diagnostics.

• Spearheaded the development of high-performance microservices using Java 17, Spring Boot, Spring Cloud, and C# interfaces,

enabling Trident 2.0 to support 100+ enterprise applications and achieving a 90% reduction in deployment lead time.

• Engineered robust backend automation layers integrating GitHub Actions, Jenkins, and Kubernetes, using Maven and

Subversion (SVN) for version control, accelerating delivery cycles from 14 to 2 days, saving $8M+ annually through release

automation.

• Built modular and accessible UI components with React.js, TypeScript, and Tailwind CSS, integrating legacy modules with

• Integrated with AZURE Cloud (AKS, AZURE APP SERVICES), MongoDB Atlas, and Kafka-based pub/sub layers to ensure scalable

deployments, audit logging, and event-driven data processing across multi-region microservices with 99.99% uptime.

• Embedded DevSecOps practices by automating security compliance gates (e.g., vulnerability scanning, OWASP checks,

policy-as-code) into CI/CD workflows, reducing manual intervention by 80% and strengthening SOX & PCI-DSS compliance

posture.

• Collaborated in high-velocity Agile teams using JIRA, Confluence, and Git, facilitating cross-functional teamwork with QA,

DevOps and Security, increasing team velocity by 35% and delivering strategic business capabilities faster.

• Actively mentored junior developers, led collaborative code reviews, and promoted a continuous improvement culture in a

distributed cloud-native environment, contributing to high-quality engineering delivery.

• Engineered 25+ RESTful and GraphQL microservices using Java 11, Spring Boot, Quarkus, JPA, and Hibernate, deployed on

GCP (GKE, Cloud Functions) and AWS (EKS, Lambda, API Gateway), and integrated with SOAP interfaces and Maven build

pipelines to reduce latency by 40%.

• Integrated modern authentication protocols, including OAuth 2.0, JWT, Spring Security, SSO, and NodeJS-based access

gateways to secure customer data, aligning with IAM and WCAG standards.

• Developed scalable, responsive UIs with React.js, Redux, TypeScript, and Material-UI, while also maintaining Angular and

JQuery components, achieving a 99.8% Lighthouse performance score.

• Enhanced observability using ELK Stack, Prometheus, Grafana, and Kafka stream processing to enable real-time monitoring,

incident response, and distributed log collection in cloud environments.

• Containerized services using Docker, orchestrated via Kubernetes (GKE, EKS), and deployed through CI/CD tools like GitHub

Actions, Jenkins, and Terraform, along with OpenShift clusters for hybrid deployment models.

• Built and optimized data layers with PostgreSQL, Cloud Spanner, Redis, MongoDB, and relational databases, supporting high

throughput operations including transaction logs and audit trails across front-end and back-end services.
