Summary

Software & Sytems Engineer with over 20 years of experience building scalable applications, platforms, developer tools, and distributed systems. Specialized in Ruby on Rails, infrastructure, and automation, I consistently deliver complex systems that improve reliability, performance, and developer productivity.

My focus is on technical design and hands-on implementation, having built large-scale infrastructure for high-traffic applications, internal developer platforms, and specialized tooling for business continuity and disaster recovery. While engineering remains my core strength, I have also stepped into leadership roles when required, scaling teams, mentoring engineers, and driving initiatives, always ensuring a strong technical vision and high standards of quality.

Experience

Intellum – Director of Systems Engineering (Jun 2023 – March 2025, Remote, US-based company, HQ in Atlanta, GA)

Enterprise Learning & EdTech

As a Director, I broadened my scope of impact to lead cross-team and company-wide technical initiatives, while remaining deeply involved in architecture, system design, and hands-on implementation.

Key Achievements

  • Built a cross-cloud disaster recovery platform, automating backups and restores across AWS and GCP. Reduced MTTR from 24h to 8h (67% improvement), meeting a 24h SLA and strengthening business continuity for millions of monthly learners.
  • Redesigned the application’s asset proxy, replacing Apache2 + mod_perl with Nginx + Lua. Enabled multi-region integration across applications, modernized request authentication with AWS SigV4 and strong cryptography, eliminated an unmaintainable legacy component, and improved request performance by up to 20%.
  • Built proofs-of-concept for IAM improvements in AWS and GCP, then drove adoption across engineering teams. Defined IAM roles and service accounts, replaced long-term credentials, and integrated AWS Identity Center, improving security posture and reducing operational risk.
  • Drove adoption of continuous deployment, increasing release frequency from weekly to multiple daily deployments, and implemented a company-wide release notes system for cross-department visibility, maintaining 99.95% SLA uptime.

Intellum – Systems Engineering Manager (Feb 2021 – Jul 2023)

I was tasked with growing and restructuring a single-person operation to a full team, hiring and onboarding engineers, all while remaining hands-on with platform design, tooling, and day-to-day operations, spending up to 50% of my time doing individual contributor work.

Key Achievements

  • Developed and maintained a CLI used daily by 40+ engineers, automating secure server access with short-lived keys, pre-built log queries, and environment management across clusters. Reduced onboarding time and operational friction significantly.
  • Optimized AWS costs by 20%, generating $100K+ annual savings through reservation automation, audits, and service deprecations.
  • Developed internal Rails tooling for DNS management, SSL automation, and provider integrations, improving security and streamlining communication between departments and clients, reducing back-and-forth with Support teams.
  • Hired and structured the team, including Systems Engineers, DevOps Engineers, and SREs. Designed interview processes and technical tests to ensure high-quality hires and accelerate onboarding.

Intellum – Senior Systems Engineer (Dec 2018 – Mar 2021)

Hired to stabilize and scale a fragile infrastructure as the company grew. Designed and built an Internal Developer Platform (IDP) to deploy Ruby on Rails and Node.js applications, introducing infrastructure-as-code, automation, and CI/CD practices. Delivered a robust, scalable platform capable of handling major spikes in traffic, laying the foundation for modern DevOps operations.

Key Achievements

  • Designed and implemented a robust automation framework covering all infrastructure needs, IaC, package management, CI, and deployments, using Terraform, Terragrunt, Ansible, Jenkins, Spinnaker, and Nexus to enable reproducible, maintainable, and scalable operations.
  • Implemented Infrastructure-as-Code for 90% of existing infrastructure and all new systems, managing 100+ custom Terraform modules. Automated server provisioning with 30+ custom Ansible roles, reducing manual intervention and simplifying operations.
  • Developed a self-service deployment platform, reducing deploy time from a full morning once per week to less than one hour several times per week, while ensuring 99.95% uptime with no SLA penalties.
  • Scaled infrastructure from <20 to 550+ servers, maintaining stability and performance under rapid growth and high traffic.
  • Handled high-profile live events and conferences for thousands of concurrent users, pushing platform limits and ensuring stable performance.

Schibsted Media Group – Staff Infrastructure Engineer (Jul 2015 – Dec 2018, Barcelona, Spain)

I built developer-focused infrastructure solutions, improving automation, security, and scalability at the platform level. My work spanned managed databases, CI/CD, and security automation.

Key Achievements

  • Developed self-service database management tools for 30+ Cassandra, Kafka, and Zookeeper clusters across 100+ servers, primarily in Python with some Go, reducing manual work by 70% and ensuring platform availability.
  • Developed key components of a self-service VPN platform used by 1,000+ engineers, building backend APIs (Python) and frontend (Ember.js), and supporting services in Go, deployed via fully automated CI/CD pipelines, achieving 99.9% SLO availability and reducing operational overhead.
  • Initiated a template repository for infrastructure projects, standardizing tooling and automation, later expanded collaboratively by other teams to simplify project setup.

XING – Senior Software Engineer & DevOps (May 2011 – Jul 2015, Barcelona, Spain)

I worked across Rails backend and frontend development and DevOps, supporting developer productivity, infrastructure automation, and CI/CD.

Key Achievements

  • Led a team of 10 engineers in the development of XING’s Talent Manager, a tool that enabled a new Recruitment B2B business line, launched at Zukunft Personal, Germany’s largest HR fair, built with Ruby on Rails and JavaScript (Backbone & Marionette.js).
  • Built backend APIs and services using Ruby on Rails, to integrate with the event platform of a newly acquired company, improving workflow efficiency and enabling new business functionality.
  • Maintained development environments for 250+ engineers, automating provisioning and infrastructure with VMware, Chef, and Docker, reducing setup time and enabling smoother engineering workflows.
  • Scaled and optimized Ruby on Rails applications for performance and high availability.
