Freelance Offerings

Tailored production-grade solutions designed for maximum uptime, high scalability, and seamless deployment speed.

Distributed Systems & HA

Designing reliable architectures using active-passive and active-active setups. Configuring high-availability database routing (pgpool-II, PostgreSQL failovers) and traffic load balancing.

  • Resilient failover strategies
  • Load balancing (NGINX, Traefik)
  • Zero single point of failure (SPOF)

Bare-Metal & Linux Admin

Enterprise server configuration, OS installation, system hardening, and administration. Automation of repetitive system tasks using custom Bash, Python, and PowerShell scripting.

  • System hardening & security patching
  • Performance tuning & kernel tweaks
  • Task automation & cron scripting

Cloud & Kubernetes Engineering

Designing multi-cloud infrastructures (Azure/GCP) using IaC (Terraform). Provisioning production-ready Kubernetes (AKS, GKE) clusters, managing container workloads, and administering core cloud services.

  • Multi-Cloud Infrastructure (Azure, GCP)
  • Production Kubernetes Administration
  • Optimized Docker & Helm orchestration

CI/CD & GitOps Automation

Building declarative, robust release pipelines using GitLab CI, Azure DevOps, Jenkins, or GitHub Actions. Implementing GitOps synchronization with Argo CD for declarative environments.

  • Standardized reusable pipeline templates
  • Security scanning (Trivy, SonarQube)
  • GitOps pull-based rollouts

Observability & Monitoring

Enabling comprehensive insight into system states. Deploying Grafana, migrating legacy dashboards (SSRS) to modern visual interfaces, and implementing proactive notification alerts.

  • Custom Grafana dashboards
  • Log gathering & metrics tracing
  • Teams / Slack alert integrations

DevSecOps & Hardening

Integrating automated security checks within pipelines. Hardening bare-metal Linux server environments, automating SSL/TLS certificate renewals, and enforcing IAM policies.

  • Pipeline vulnerability scans (Trivy, SonarQube)
  • OS-level security hardening & patching
  • Automated SSL (Cert-manager, Traefik)

Production Workloads & Failures Handled

Practical deep dives into architectural redesigns, cloud migrations, and critical systems failure prevention.

Azure Kubernetes .NET 8

Multi-Environment Azure Cloud & AKS Platform Orchestration

Designing and managing scalable multi-environment Azure Cloud infrastructures deploying AKS container nodes. Led runtime dependency audits of 140+ packages, and engineered backward-compatible adaptations running across VM and Kubernetes clusters.

PostgreSQL Java Jenkins

High-Availability pgpool-II Cluster Automation

Automated the deployment and health verification of active-passive pgpool-II cluster configs for Postgres database engines. Built custom command-line utilities and Spring Boot user interfaces for instant node failover checking.

Windows Server PowerShell Azure DevOps

Instance-Isolation Model in UCD & Shared Infrastructure

Engineered a hash-based manifest-driven instance isolation model in UrbanCode Deploy for multi-plant deployment environments. Saved major infrastructure costs by resolving IIS sites, ports, databases, and filesystem collisions.
