- centric shopping experiences across all channels with disruptive retail tech solutions. Get on board and make your own contribution to the industry!

Our customer is a multinational corporation with more than a century of history and offices in over 180 countries. Their most ambitious goal at the time is to introduce a range of Reduced-Risk Products (RRPs). The target audience is more than 1 billion of consumers around the globe.

AWS EKS – managed clusters with Karpenter, ALB ingress, IAM integration, and
- optimized workloads

Azure AKS – enterprise environments with Azure AD SSO, CSI, and autoscaling

Google GKE – workload identity integration and
- optimized build pipelines

Open
Shift (on-prem/cloud) –
- on experience with 3. x and 4. x clusters, including cluster operators and lifecycle management

Rancher –
- cloud environments with centralized policy enforcement and workload monitoring

Tooling & Ecosystem

Argo Ecosystem (end-to-end Git
Ops):

Argo CD – declarative
- env deployments using the
-
- apps pattern

Argo Workflows – Kubernetes -native CI workflows for build/test/deploy

Argo Rollouts – blue/green, canary, and progressive delivery strategies with Istio

Argo Events – Git
Ops-driven event triggers for reactive pipelines

Helm (custom charts, chart libraries, deployment templating)

Kustomize – environment overlays for
-
- code

Vault +
- secrets – secure secrets delivery via Kubernetes controllers

Autoscaling & Efficiency

KEDA –
- driven autoscaling from custom metrics (Kafka, Prometheus, Rabbit
MQ, etc. )

Karpenter –
- gen cluster autoscaler for dynamic provisioning of spot/on-demand nodes

HPA & VPA –
- grained
- level autoscaling based on CPU/memory or custom metrics

Cluster Autoscaler (legacy, tuned for GKE & AKS before migrating to Karpenter)

Security & Policy

cert-manager – ACME automation and
- signed certificate issuance

OPA/Gatekeeper –
-
- code for image whitelisting, label enforcement, resource limits

Istio – service mesh for secure
-
- service communication (m
TLS, JWT auth, traffic shifting)

Hardened workloads via Pod
Security
Context, App
Armor/Seccomp profiles

Monitoring & Observability

Prometheus, Grafana, Loki, Alertmanager – full metrics and log stack per namespace/env

Jaeger + Open
Telemetry – distributed tracing and performance monitoring

Fluent Bit, Elasticsearch, Kibana – centralized logging pipelines

Readiness/liveness probes and SLO-based alerting

Key Projects & Achievements

Designed and built a fully Git
Ops-native deployment platform using the complete Argo stack integrated with Vault, KEDA, and custom Helm charts

Migrated 30+ legacy apps from Docker Swarm and VM-based environments to Kubernetes with minimal downtime

Implemented progressive delivery using Argo Rollouts + Istio for safe and reversible changes

Built dynamic dev/test preview environments using Dev
Space and Argo Events

Enabled secure workload identity and multitenancy across EKS and GKE clusters

Responsibilities:

• Design, build, and maintain software delivery pipelines and infrastructure that support continuous integration, delivery, and deployment.
• Collaborate with development and operations teams to ensure that software is delivered with high quality, speed, and reliability.
• Automate manual processes, such as testing, deployment, and monitoring, to improve efficiency and reduce errors.
• Develop and maintain monitoring and alerting systems to proactively identify and address issues in production environments.
• Troubleshoot production issues, conducting root cause analysis and implementing remediation plans.
• Manage and scale infrastructure resources, such as servers, databases, and cloud services, to ensure optimal performance and
  - effectiveness.
• Implement security best practices and ensure compliance with industry standards and regulations.
• Continuously learn and keep up to date with new technologies and industry trends to improve system performance, security, and efficiency.
