Architecting scalable distributed systems and optimizing high-throughput infrastructure.

Professional Experience

DevOps Intern

Dec 2025 - Present
Aurva• Bengaluru
  • Designed aurva-helm-commons Helm library orchestrating 15+ microservices with IRSA/Workload Identity federation and AWS Secrets Manager CSI, reducing new environment setup from a Helm expert to editing a single values file.
  • Built AWS control plane (Terraform + Helm) covering VPC, EKS, RDS, OpenSearch, IAM, S3, and CloudTrail with full air-gapped PrivateLink mode, cutting fresh deployment time from 2-3 days to under 45 minutes.
  • Authored cross-account, CSPM compatible IAM Terraform module with OIDC-based IRSA federation and aws:SourceVpc conditions, eliminating long-lived credentials and reducing a 2-3 hour manual setup to a 5-minute terraform apply.
  • Deployed GCP data plane with Workload Identity, GCS bucket provisioning, and optional tainted node pool attachment to existing GKE clusters, enabling multi-cloud support without per-customer manual playbooks.
  • Wrote hardened Bash installers for eBPF collector, DBProxy, and PostgreSQL 18 with preflight checks, retry/backoff, rollback, and CDN/air-gapped paths — cutting standalone server onboarding from 4-8 hours to under 10 minutes.

Software Engineer

Dec 2024 - Aug 2025
Piovation GmbH• Germany
  • Architected SSH connection pooling for remote Linux servers, achieving 115% throughput improvement (8K → 17K req/s) while significantly reducing per-request resource overhead.
  • Built high-throughput gRPC gateway layer with bidirectional streams for hardware communication and efficient API-to-Linux command translation across distributed infrastructure.
  • Led full OpenTelemetry instrumentation for distributed tracing and metrics collection, reducing system debugging time by 40% and improving production observability.
  • Standardized protobuf and gRPC best practices across engineering teams, improving code maintainability, accelerating development velocity, and reducing integration complexity.
  • Optimized system architecture for high-availability deployments, maintaining consistent 99.9% uptime across production environments under sustained peak traffic loads.

Backend Developer Intern

May 2024 - Oct 2024
Dofollo AI• Remote
  • Engineered Redis-based distributed caching with intelligent invalidation strategies, cutting database load by 40% and significantly improving application response times.
  • Designed RabbitMQ event-driven architecture improving system reliability by 30% through decoupled logging, mailing, and notification services across microservices.
  • Orchestrated Docker Swarm microservices deployment with automated health checks, achieving 50% reduction in service downtime during critical deployments and updates.
  • Developed gRPC protocols with auto-generated client-server stubs and connection pooling, improving inter-service communication efficiency by 20% and reducing latency.
  • Built Go cron scheduling module for incremental billing and URL crawling tasks, increasing scheduling accuracy by 25% and eliminating manual operational intervention.
