Work Experience
Software Engineer — DevOps / DevSecOps
WATI (West Advanced Technologies India Pvt. Ltd.)
- Reduced production vulnerabilities by 40% by engineering multi-stage Jenkins pipelines with mandatory SonarQube SAST quality gates, OWASP Dependency-Check, and Trivy container image scanning.
- Collapsed environment provisioning from days to under 30 minutes by re-architecting AWS infrastructure as modular Terraform IaC with remote state in S3 and DynamoDB locking.
- Maintained zero-trust Kubernetes (EKS) posture via granular RBAC, Network Policies, Secrets Management, and Resource Quotas across all workloads, eliminating lateral movement risk between namespaces.
- Right-sized CPU/memory requests using VPA recommendations and implemented HPA with custom Prometheus metrics, reducing pod restarts by ~40% and lowering infrastructure cost; added PodDisruptionBudgets and standardized probes to eliminate downtime during node upgrades.
- Refactored Dockerfiles with multi-stage builds and distroless/alpine base images, cutting image size by 60–70% and improving CI build speed and audit readiness.
- Migrated Jenkins to Kubernetes-based dynamic agents and shared pipeline libraries, parallelizing build/test stages and reducing overall build time by ~50%.
- Improved deployment consistency by 30% by containerizing legacy and microservices applications with Docker, eliminating environment drift; automated CIS benchmark compliance across 50+ EC2 instances using Ansible playbooks.
- Cut Mean Time to Recovery (MTTR) by 25% by building real-time observability dashboards in Prometheus/Grafana and Datadog with proactive alerting.
Projects
AppNova AI — Enterprise Multi-Agent Modernization Platform
- Contributed to an 11-agent platform that analyzes legacy codebases in parallel to produce modernization reports, supporting orchestration of 5 LLM providers with automatic API key rotation, rate-limit detection, and provider fallback.
- Helped test and validate individual agent modules — including architecture analysis, security scanning, and DevOps planning.
GovGenie — RAG-Powered RFP Response Generator
- Contributed to a Retrieval-Augmented Generation tool that cuts government bid-response writing time from days to hours, assisting with retrieval pipelines and prompt workflows.
- Helped build the ChromaDB-backed retrieval layer that indexes government RFP source documents and supported prompt-template tuning.
Kubernetes End-to-End CI/CD Pipeline — Java Web Application on AWS EKS
- Engineered a 9-stage Jenkins pipeline building and scanning separate application and database images before every registry push.
- Provisioned the target AWS EKS cluster with Terraform IaC and built a second Jenkins pipeline that deploys via a least-privilege Kubernetes RBAC service account.
