## Headline

Immediate Joiner \| Senior Software Engineer \| Go \(Golang\) \| Kubernetes Controllers & Distributed Systems \| Cloud\-Native & Storage Platforms \| Ex\-InfraCloud \| Remote / Hybrid / On\-site

## About

Software engineer with 5\+ years of experience building reliable, performance\-tuned, cloud\-native systems in Go and Python, with deep specialization in Kubernetes controller engineering, distributed systems, and data protection/backup infrastructure\. At InfraCloud Technologies, I work on an enterprise\-grade Kubernetes data management product \(backup & disaster recovery\) serving large production clusters\. My work spans: • Resolving concurrency races and silent stalls in distributed Kubernetes controllers \(monotonic revision counters, non\-blocking transient\-retry state machines\) • OS\-level storage optimization in Go \(posix\_fadvise page\-cache hints, block\-aligned disk\-cache accounting\) — \~20% faster backups and \~30% lower RAM on IOPS\-constrained clusters; 12% throughput gain on 100M\+ file workloads • Kubernetes resource lifecycle safety \(OwnerReferences, two\-factor GC eligibility, CEL\-based CRD immutability validation\) • End\-to\-end ownership: design docs → architecture review → implementation → testing → release pipelines; mentoring and onboarding new engineers Open source: merged contributions to Kanister \(RepositoryServer workflows, Kopia command wrappers, AWS SDK v2 migration\); acknowledged performance/infra bug reports in Kopia and Red Hat Operator SDK\. Earlier: MuleSoft Runtime Fabric on AWS EKS \(Apisero\); multi\-cloud orchestrator managing hundreds of VMs/K8s clusters across AWS, Azure, GCP, and KVM \(GS Lab\)\. Core stack: Go, Python 3, Kubernetes \(controllers, CRDs, client\-go, Kubebuilder, Helm\), AWS \(EKS, S3, IAM\), Docker, OpenShift, MongoDB, Flask, Git/CI\-CD, Prometheus/Grafana\. Open to Senior Backend / Platform / Kubernetes / Cloud Infrastructure roles\.

## Work experience

Product Engineer at InfraCloud Technologies \- An Improving Company, May 2022 \- Sep 2026 · 4 yrs 5 mos, Pune City, Maharashtra, India, Product Engineer on an enterprise\-grade Kubernetes data management \(backup & DR\) platform for large\-scale production clusters\. • Resolved critical concurrency races in a distributed Kubernetes controller \(shared backup server\): eliminated silent 2\-hour export stalls and credential flush races via monotonic revision counters and non\-blocking transient retry gates\. • Optimized OS\-level storage behavior in Go: posix\_fadvise page\-cache hints via SyscallConn and block\-aligned disk\-cache accounting — \~20% faster backups, \~30% lower RAM on IOPS\-constrained clusters; prevented ENOSPC pod evictions on terabyte\-scale backups\. • Improved backup throughput by 12% \(validated on 100M\+ file workloads\) by migrating cache to bounded emptyDir volumes with Helm\-configurable size limits\. • Stopped leakage of dynamic Services/NetworkPolicies/Secrets via native OwnerReferences and two\-factor GC eligibility checks; enforced CRD field immutability with CEL validation rules \(zero webhook overhead\)\. • Owned features end\-to\-end: design/architecture docs, review approvals, implementation, testing, pre\-prod release pipelines; mentored new joiners and led product onboarding\. • Open source: merged PRs to Kanister; acknowledged bug reports in Kopia and Operator SDK\.

Senior Software Engineer at Apisero Inc\., Aug 2021 \- May 2022 · 10 mos, Pune Division, Maharashtra, India, • Designed and implemented MuleSoft Runtime Fabric on AWS EKS, enabling resilient, scalable API microservice deployments for enterprise clients\. • Built high\-quality, resilient integration APIs; conducted technical workshops on emerging technologies for client teams\. • Won the Raving Reviews Award multiple times for excellent client feedback and proactive technical initiatives\.

Software Engineer at GS Lab, Sep 2020 \- Aug 2021 · 1 yr, Pune Division, Maharashtra, India, • Co\-built a Multi\-Cloud Service Orchestrator \(Python 3, Flask\-RESTful, MongoDB, Go\) managing hundreds of VMs and Kubernetes clusters across AWS, Azure, GCP, Alibaba, and on\-prem KVM from a single dashboard; deployed on Kubernetes and later productized by the company\. • Shipped containerized applications with Docker; deployed and operated on Kubernetes and OpenShift\. • Led client consultations for requirements gathering; delivered customized, tested, well\-documented solutions\.

Intern at GS Lab, Aug 2019 \- Sep 2020 · 1 yr 2 mos, Pune/Pimpri\-Chinchwad Area, • Engineered reliable, efficient codebases for in\-house applications; hands\-on across Python 3 backend and DevOps practices \(Docker, Kubernetes\)\.
