• As the companys first dedicated DevOps engineer, automated DigitalOcean provisioning with Terraform and Ansible, cutting environment setup from ~2 hours to under 3 minutes
• Designed an open-source DevSecOps toolchain (SAST, SCA, IaC, container, and secret scanning) across 70+ repositories, avoiding ~$225K/year in commercial licensing (Snyk Enterprise, GitHub Advanced Security)
• Implemented the technical security controls behind the companys first ISO 27001 certification, unlocking enterprise B2B deals gated on the standard
• Built 10+ GitHub Actions CI/CD pipelines deploying to Kubernetes via ArgoCD GitOps, enabling multiple production releases daily
• Ran a 6-microservice Digital Product Passport platform across 5 Kubernetes clusters in stable production (30 service instances)
• Architected the observability stack (Prometheus, Grafana, Loki, Alertmanager) on Kubernetes via Helm, with proactive Slack alerting so failures surface to on-call before users report them
• Containerized a complex Catena-X / Eclipse Tractus-X umbrella chart — wiring ~60 microservices into Kubernetes manifests and Docker Compose (not offered in Tractus-X OSS) to run the full stack on a single
laptop
• Eliminated $252/mo per-developer cloud VMs across 17 engineers (~$50K/year) by making that stack locally runnable, easy to develop, deploy, and demo
• Designed a compliance-driven AWS migration (landing zone, networking, cutover sequencing) for 119 droplets
and delivered a Terraform/Pulumi IaC proof-of-concept making the target infrastructure reproducible and auditable

• Owned the full delivery pipeline solo — CI/CD on GitHub Actions and a Turbo-cached monorepo on a Next.js/tRPC stack with Prisma and PlanetScale MySQL — running the platform at near-zero infrastructure
cost on free-tier managed services
• As the sole engineer, architected and shipped a healthcare management platform end-to-end — appointment scheduling, doctor listings and profiles, an admin panel, and a full role-based relational data model
• Engineered serverless, low-cost features — build-time static generation with incremental regeneration (Next.js ISR, no Redis layer), real-time doctor availability on Firebase Realtime Database with custom security rules, and Vercel cron notifications (email/SMS)

• Co-created a DevOps curriculum covering Docker, Kubernetes, AWS, and microservices
• Delivered hands-on training to 300+ engineers on deployment, containerization, load balancing, and microservices networking

• As Tech Lead, led 10+ engineers across three products, driving technical direction, scoping, and delivery
• Owned CI/CD on GitHub Actions and multi-cloud deployments across Vercel, AWS App Runner, and GCP Cloud Run/Firebase, with cached lint, type-check, and build steps for fast developer feedback
• Deployed and scaled a padel matchmaking and booking platform that grew to 9, 000+ users, and built its real-time chat (PubNub) synced across web and mobile
• Architected a Turborepo monorepo (Next.js web + Expo/React Native mobile) sharing tRPC APIs and types, giving the team end-to-end type safety and faster builds
• Cut frontend network calls by 40% and backend execution time by 50% by resolving database query and backend bottlenecks

• Built a serverless data pipeline on AWS Lambda that processed
Refinitiv and S&P SME data into the database, with CloudWatch for monitoring and debugging
• Owned AWS Amplify deployments and code reviews, and integrated serverless KYC and external APIs via API Gateway and Lambda
