In early 2022, Deloitte Digital was engaged by a state government health program to deliver a Vaccine Management System (VMS) on Salesforce. The system needed to manage COVID-19 vaccination inventory distribution, a vaccinator portal, and a vaccine recipient portal — at scale, across a state-wide immunisation program.
My Role
I was placed in the CI/CD stream of the project — a technically demanding role that required participating across both the functional and development tracks simultaneously. My work spanned Salesforce configuration, Apex development, Flow design, and DevOps, with direct client communication throughout.
The User Provisioning Problem
The VMS had a significant operational challenge: onboarding healthcare workers as Salesforce users required a 23-step manual process that took an administrator approximately 23 minutes per account. With hundreds of vaccinators needing access, this was a serious bottleneck.
I designed and built an automated User Provisioning solution using Salesforce Flows and Apex that collapsed this to 3 minutes per user account — an 87% reduction in manual effort.
At a high level, the solution combined a guided Screen Flow that walked administrators through the required inputs with validation, Apex to handle the record creation and error paths, and role-based permission bundles applied automatically once provisioning completed. The specific intake channels, access-package composition, and approval routing are omitted here — they’re operational detail of a client environment rather than transferable engineering.
The transferable part is the shape of the win. Nobody had ever timed the manual process end to end. Once someone did, the 23 discrete steps turned out to be mostly deterministic transformations of four inputs, and the handful that genuinely needed judgement were the only ones worth keeping a human on. Most “we need to automate this” problems look like that once measured.
Flow Development
I designed and built 7 Flows across the project for distinct features:
- User Provisioning (Screen Flow)
- Inventory allocation triggers (Record-Triggered Flows)
- Appointment reminder sequences
- Cancellation and rescheduling logic
- Permission management automations
Each flow was documented and peer-reviewed before deployment, with test cases maintained in the project’s Deployment Package.
DevOps and Client Communication
Working in the CI/CD stream meant maintaining feature branches and pull requests across a team with parallel development tracks. I managed merge conflicts and defect resolution across sprint cycles, and prepared solution design diagrams and client-facing decks for workshop presentations and playback sessions.
Testing
I created and executed test cases against all VMS user stories, covering Salesforce configuration, third-party app integration, and data handling. Defects were triaged in collaboration with client BAs and the offshore development team.
Results
- User provisioning: 23 minutes → 3 minutes per user account
- 7 Flows delivering automation across the vaccination program
- Full CI/CD delivery with managed deployment packages
- Client workshops and playback sessions delivered throughout
The VMS engagement was one of the more technically varied projects I’ve worked on at Deloitte — spanning Apex, Flow, DevOps, and direct client delivery in a high-stakes public health context. The user provisioning automation in particular showed how targeted automation design can create immediate, measurable operational impact.
Client details are generalised. This describes a state government health engagement delivered through Deloitte Digital; the client, environment specifics, and operational detail of the provisioning process are deliberately omitted. The technical approach, timings, and outcomes are as delivered.
