Work Experience
Sr. Digital Engineer 2 (Lead Engineer)
Tata Digital Pvt Ltd. · Payment TechOps
- Engineered DR switchover strategy for high-concurrency payment systems, transitioning infrastructure across regions with zero data loss.
- Spearheaded migration of 15+ AKS clusters from NGINX Ingress to Gateway API framework, eliminating long-term technical debt.
- Designed automated CI/CD framework supporting 200+ microservice deployments with standardized templates and zero-downtime strategies.
- Implemented LGTM observability stack on AKS, achieving 66% monthly cost reduction vs Azure Application Insights.
- Deployed RabbitMQ & ELK Stack with Filebeat on AKS for end-to-end distributed application monitoring.
- Built reusable Terraform modules for Azure resources (VMs, Web Apps, AKS) enabling consistent multi-environment deployments.
- Architected DevSecOps framework with Checkmarx (SAST), DefectDojo, and SonarQube for 100% pre-deployment vulnerability scanning.
- Developed automated service recovery solution by creating systemd service files for 7–10 Java Spring Boot applications across ~20 Azure Linux VMs, enabling automatic process startup post-patching — eliminating 4+ hours of manual intervention per maintenance window and saving 95% of recovery time. 🏆 Quarterly Employee Award ✨
Associate, Analytics Engineering — DevOps
MSCI Inc.
- Led the lift-and-shift migration of services from Azure Cloud to an on-premises Rancher Kubernetes cluster, achieving a 30x improvement in API-to-API communication through cluster collocation.
- Authored YAML manifests for Azure DevOps pipelines to build and push Docker images to Azure Container Registry (ACR) and deploy Helm charts to AKS clusters (Deployments, Secrets, Ingress, ConfigMaps, PVC, PV) with HPA for autoscaling.
- Provisioned PVC and PV Kubernetes objects to persist pod log files (JVM heap dumps, GC logs) to NFS-backed Azure Files storage.
- Configured NGINX Ingress Controller for service load balancing and enforced TLS/SSL termination for secure API communication.
- Created Azure DevOps build pipelines for Gradle-based Java and Scala projects, publishing versioned Docker images to ACR.
- Designed application deployment pipelines using Azure Pipelines for streamlined releases across Dev, UAT, and Production environments.
- Implemented REST endpoints for readiness and liveness probes to ensure robust container health monitoring.
- Integrated WhiteSource vulnerability scanning into the container build process to enforce security compliance before deployment.
- Configured Dependabot with Gradle to automatically generate pull requests for dependency updates, proactively addressing security vulnerabilities.
- Implemented Azure Application Insights to monitor container resource utilization (memory, CPU, request throughput) and configured alerting rules for proactive incident response.
- Integrated Application Insights with services for centralized logging and telemetry collection using the OpenTelemetry (OTel) agent.
- Integrated SonarQube with the CI pipeline using the Scoverage tool to enforce code quality standards and track code coverage metrics.
- Developed Bash scripts to automate repetitive pipeline tasks, reducing manual intervention and improving deployment consistency.
Associate, Analytics Engineering — Developer
MSCI Inc.
- Designed and implemented a high-performance REST API server using JAX-RS and Scala, leveraging Scala's functional and object-oriented capabilities to deliver efficient, scalable, and maintainable code.
- Implemented concurrent and parallel processing using Scala Futures, Parallel Collections, and advanced collection operations to significantly improve application performance and throughput.
- Managed asynchronous task execution using CompletableFuture, ensuring efficient utilization of system resources and optimized performance for multi-threaded applications.
- Implemented API authorization using OAuth 2.0, JWK, and JWT to enforce secure access control across services.
- Integrated SonarQube with the Scoverage tool and increased code coverage from 60% to 91%, improving overall code quality and reducing technical debt.
- Optimized build and regression test performance by implementing parallel execution of JUnit tests written with ScalaTest (WordSpec), reducing overall test duration by 30–40%.
- Developed a performance and load testing framework using Gatling to benchmark and validate the scalability of the analytics engine API.
- Authored complex SQL queries against relational databases to validate data integrity returned by the DB API layer.
- Developed a Python automation tool to publish TeamCity test results to Confluence pages, streamlining reporting workflows.
