Executive Summary

Platform Engineer with 13+ years building cloud platforms, delivery standards, and reliability practices. 10+ years on AWS (Solutions Architect Professional, Security Specialty).

At Mercell I work in a 4-person platform team supporting 50+ engineers across 7 product teams. Shared-platform adoption grew from about 10% to 50% of applications — near-complete adoption of modern, platform-eligible workloads. Coordinated production releases went from 3–4 per week to 3–4 per day (about 5x on the measured baseline). Platform support demand fell about 60%. AWS infrastructure cost fell about 20% through rightsizing, Fargate, autoscaling, and spot.

I led the rollout of Claude Code to about 50 developers across 5 teams: isolation guardrails, shared MCPs and skills so code and company knowledge stay aligned, and agents for pull-request review, triage, and troubleshooting.

Key Achievements

  • Platform adoption: 10% to 50% of applications on shared Terraform/Terragrunt, CI/CD, and Backstage, for 50+ engineers across 7 teams at Mercell.
  • Delivery: Coordinated production releases from 3–4/week to 3–4/day (about 5x on the measured baseline).
  • Developer experience: Platform support demand down about 60% (about 50 to 20 requests per sprint) via self-service workflows and practical docs.
  • AWS cost: About 20% reduction at Mercell (rightsizing, Fargate, autoscaling, spot). At KIU, infrastructure spend from about $600k to $500k per month ($1.2M annualized).
  • Reliability: E-commerce availability from about 90% to 99% on an airline platform serving 10–25M passengers/year. On-call incidents from about 2/week to 3/month.
  • Standards: GitOps with Argo CD as the company-wide deploy standard at KIU (40+ services on EKS), with automatic rollback on error rate.
  • AI enablement: Led Claude Code rollout to about 50 developers across 5 teams, with isolation guardrails, MCPs, skills, and agents for review, triage, and troubleshooting.
  • Application-level AWS: EventBridge-triggered Lambda that deploys API Gateway changes GitOps was skipping, after missed deploys caused incidents. Python reconciles AWS and GitHub state.

Certifications

  • AWS Certified Security — Specialty (2024)

Core Competencies

Platform Engineering

AWS: EKS, ECS, Lambda, API Gateway, EventBridge, SQS, DynamoDB, Step Functions, Landing Zones, multi-account governance. 10+ years. Kubernetes: EKS, Helm, GitOps with Argo CD, Fargate Infrastructure as Code: Terraform, Terragrunt, AWS CDK, CloudFormation, Ansible Cost: AWS-native FinOps. About 20% reduction at Mercell. $1.2M annualized savings at KIU. Spot and rightsizing. No claimed savings from reservations that were not purchased.

Delivery and reliability

CI/CD: GitHub Actions, GitLab CI, reusable workflows Observability: Prometheus, Grafana, New Relic, CloudWatch. Elasticsearch for log analysis. Security and compliance: GDPR, PCI-DSS controls, AWS security services used in landing zones and bank CI/CD

AI-enabled engineering

Rollout: Claude Code to about 50 developers across 5 teams Controls: isolation guardrails, shared MCP servers, skills that keep generated code and company knowledge aligned Agents: pull-request review, triage, troubleshooting

Scope, not a management pitch

Technical leadership of a 5-engineer team at KIU. At Mercell: platform roadmap, hiring interviews, deployment-strategy presentations, and a CI/CD hackathon with product developers. C-level incident and SLA reporting was at KIU, not Mercell.

Professional Experience

Wypoon / Mercell — Platform Engineer

Sep 2024 – Present | Utrecht, Netherlands (Hybrid)

Platform team of 4, supporting Mercell’s European procurement platform after EU Supply, Negometrix, and Cloudia moved onto AWS.

  • Standardize Terraform/Terragrunt, GitHub Actions, and Backstage for 50+ engineers across 7 product teams. Adoption from about 10% to 50% of applications.
  • Coordinated production releases from 3–4 per week to 3–4 per day (about 5x on the measured baseline).
  • Support demand down about 60% (about 50 to 20 requests per sprint) after self-service workflows, a developer hackathon on CI/CD and end-to-end tests, and docs rewritten so examples come first.
  • AWS cost down about 20% via rightsizing, Fargate, autoscaling, and spot.
  • EC2 to ECS modernization and a consistent multi-account landing zone with cross-border GDPR controls.
  • EventBridge Lambda deploys API Gateway changes that CloudFormation GitOps was skipping, after missed deploys caused incidents. Python automation reconciles AWS and GitHub APIs and forces the same deploy.
  • Led Claude Code rollout to about 50 developers across 5 teams: isolation guardrails, MCPs, skills, and agents for pull-request review, triage, and troubleshooting.
  • Defined the platform technology roadmap. Take part in hiring interviews and incident postmortems.
