Work experience

Jesta I.S. — Oracle Database Administrator

Montreal, QC · Jan 2026 – Present

  • Author and maintain Oracle database change scripts to a strict internal standard covering idempotency, rollback safety, version-control headers, and trigger handling.
  • Manage cross-schema access, grants, and synonyms across the Jesta product suite, supporting both new feature work and ongoing client deployments.
  • Build and operate an AI-assisted change-script generator and validator (Anthropic Claude) that drafts compliant scripts from ticket text and scores them against internal DBA conventions; every script is reviewed by a DBA before deployment.
  • Reduce manual effort on routine database change tickets by routing them through the generator and validator pipeline.
  • Configure Oracle Instant Client integration with Node.js to allow modern applications to connect to legacy database environments.
  • Build tooling to track patch and version drift across Oracle environments, generate snapshot records, and validate schema state.
  • Serve as backup Configuration Manager — prepare full backend and frontend build artifacts for on-prem deployment or SFTP delivery to clients via the Azure artifact pipeline.

Jesta I.S. — Technical Analyst / Full Stack Developer

Montreal, QC · Nov 2021 – Jan 2026

  • Built and own VisionHUB, a full-stack internal web application that connects to multiple Oracle databases simultaneously and centralizes license management, environment metadata, and database change tracking — including Azure AD single sign-on, in-memory caching, and tuned connection pools.
  • Integrated Anthropic Claude into production tooling to extract and validate database change requests from free-form tickets, with strict structured outputs and an internal rule set.
  • Modernized legacy VB.NET DBA utilities into web-based equivalents inside VisionHUB, while continuing to maintain the WPF / C# desktop applications used for patch creation and version-control check-ins.
  • Integrated Azure Service Bus for asynchronous messaging between internal services.
  • Shipped internal Azure DevOps dashboards for pull request review and branch analytics, plus a Microsoft Teams notification bot that flags missing required reviewers.
  • Worked across Azure DevOps repos, boards, pull request processes, and CI/CD pipelines; supported IIS-hosted services on Windows Server.
