Profile

I'm a DevOps Platforms Engineer interested in technology, AI, and finance. I work with GitLab, CI/CD, Bash, Python, and agentic AI engineering tools, and I act as a product expert for GitLab, SonarQube, GitHub Copilot, and GitLab Duo, which comes with an internal developer advocacy role on the side.

DevOps Platforms Engineer

UBS · Full-time, DevOps Platforms, Core Platform Engineering

Enabled AI Software Development (Agentic AI Engineering) by supporting GitLab, SonarQube, GitHub Copilot, and GitLab Duo users with product/technical support, reporting bugs to the vendors, some critical severity and blocking users, and verifying their fixes. In practice an internal DevRel/DevEx role for those products.
Ran an AI developer tool Proof of Concept (PoC) Pilot across its administration (granting access, writing technical documentation, creating a structure for gathering feedback), its technical work (debugging user issues and technical enablement together with the vendor), and its commercials: verified usage behaviour and policies, built a custom tool for data analysis, and ran my own cost and feature parity comparison against comparable tools to advise management on options.
Ran GitLab and SonarQube platform operations: version upgrades (deprecation and breaking change analysis, implementation plans, Terraform and Ansible playbook execution, validation, and vendor liaison when something goes wrong), triaging user questions and issues from UI/UX quirks to API failures (escalating to specialised teams or the vendor when needed), maintaining documentation, FAQs, and internal knowledge content, and keeping up with the platform and feature roadmaps to bring useful new capabilities to the team's and users' attention.

DevOps Platforms Engineer (Apprentice)

UBS · Tech Degree Apprenticeship, DevOps Platforms, Core Platform Engineering

Built an end-to-end Python reporting pipeline in GitLab CI fetching 12,000+ SonarQube projects (73,000+ branches) and producing a CSV of their code quality metrics, mapped to internal application references and business division teams, published to Azure Blob Storage and consumed by a Power BI dashboard. Wrote unit and integration tests with 100% coverage in Pytest.
Enabled AI Software Development (Agentic AI Engineering) by supporting GitLab, SonarQube, GitHub Copilot, and GitLab Duo users with product/technical support, reporting bugs to the vendors, some critical severity and blocking users, and verifying their fixes. In practice an internal DevRel/DevEx role for those products.
Ran GitLab and SonarQube platform operations: 4 GitLab version upgrades and assisting SonarQube's (deprecation and breaking change analysis, implementation plans, Terraform and Ansible playbook execution, validation, and vendor liaison when something goes wrong), triaging user questions and issues from UI/UX quirks to API failures (escalating to specialised teams or the vendor when needed), maintaining documentation, FAQs, and internal knowledge content, and keeping up with the platform and feature roadmaps to bring useful new capabilities to the team's and users' attention.
Provided L1 support migrating 34 important CS applications (201 repositories) to UBS GitLab: issue templates per repo, evidence validation, running the migration pipeline, and triaging 1,100+ secret scanning findings as false positives. Trained SREs to take over L1 and moved up to L2.
Provided L2 support for a further initiative migrating 500+ CS applications (5,000+ repositories), with Power BI reporting for management and PMs. Kept the migration tool within UBS SDLC through test cases and implementation plans, and helped CUSO app teams meet a regulatory MRA by clearing technical queries and blockers.
Implemented log monitoring for SonarQube with Azure Log Analytics: resource group, decentralised workspaces, data collection endpoints, custom table definitions, and data collection rules from a single DCR pattern file, associated to VM lists per environment (Production, PREPROD, DEV), instance type (main and COBOL-specific), and deployment (primary and secondary). Built with GitLab CI/CD, Azure CLI, Bash, and HashiCorp Vault for secrets, ending manual SSH into VMs to view and share logs during incidents and improving debugging for engineering and the production SREs, who alone hold prod access under segregation of duties.
Simplified the controls that ensure development compliance in GitLab, working with the vendor on branch protection and merge request approvals to meet the 4-eyes requirements of a regulated bank.
