Platform Engineering

Design and implement cloud-native platforms on AWS and GCP. Kubernetes orchestration, infrastructure as code with Terraform, and GitOps workflows that enable teams to ship faster.

SRE & Reliability

Establish SRE practices including SLIs, SLOs, and error budgets. Comprehensive monitoring with Prometheus, Grafana, and Datadog to improve uptime and reduce incident response time.

Cloud Cost Optimization

Strategic cost analysis and optimization across GCP and AWS. Right-size resources, implement lifecycle policies, and establish ongoing governance for sustainable savings.

Security & Compliance

Implement WAF protections, secrets management, CI/CD security scanning, and compliance support for SOC 2. Defense-in-depth approach with automated policy enforcement.

CI/CD Pipeline Architecture

Build robust deployment pipelines with GitHub Actions and GitLab CI. Automated testing, security scanning, and progressive rollouts that reduce deployment risk and accelerate delivery.

Performance Optimization

Analyze and optimize application performance including database query tuning, caching strategies, and infrastructure right-sizing to improve response times and reduce resource consumption.

Client Outcomes

Real results from recent engagements

Multi-Cloud FinOps Initiative

B2B SaaS

Unlocked six-figure savings by rebalancing a multi-cloud footprint.

  • $162k annual savings across GCP/AWS, including a 5TB CloudSQL reduction
  • Optimized Cloud Armor tiering and hardened ECR lifecycle policies
  • Launched weekly billing reviews that keep spend within targets

AWS to GCP Cloud Migration

IoT Startup

Migrated an IoT control plane to GCP without service interruption.

  • Terraform-built GKE platform powering 30+ services with Prometheus/Grafana
  • Established secure site-to-site VPNs linking customer buildings
  • Adopted ArgoCD GitOps for consistent, auditable deploys

SRE Practice Implementation

E-commerce

Embedded SRE fundamentals to raise reliability for a fast-growing platform.

  • Defined SLIs/SLOs and error budgets across customer-facing services
  • Delivered GCP Monitoring dashboards, runbooks, and revamped on-call
  • Improved MTTR while enabling teams to self-serve infrastructure safely

How I Work With You

A proven engagement model focused on delivering measurable value

01

Discovery

Explore your platform, repositories, tooling, and stakeholder goals to understand where the platform is today and where it needs to go.

02

Planning

Break the work into a kanban backlog with prioritized tickets, clear owners, and right-sized sync cadence so everyone knows what’s coming next.

03

Implementation

Ship improvements in tight loops—IaC, CI/CD, progressive delivery—while pairing with your engineers through reviews, workshops, and async updates.

04

Operational Excellence

Align documentation, CI, observability, and iterative improvement plans so the platform keeps getting better long after the engagement wraps.

What Clients Say

"He led our AWS-to-GCP migration end-to-end—architecture, Terraform, and rollout—and de-risked timelines. Reliable partner across engineering and exec stakeholders."

Elias M. Kaczer CTO, InteliGlas Corporation

"Dan paired FinOps with reliability for us—cut about $160k/year across GCP and AWS, moved us to Artifact Registry and tighter Cloud Armor, and steadied Cloud Run/Redis so incidents stopped derailing launches."

Josh Atir CTO, Paper
