Selected work

Unity Gateway

Unity, Senior Product Manager II, 2024 to now

Problem: Teams across Unity exposed and secured their APIs in different ways, on legacy gateway infrastructure.
What I did: I lead strategy and roadmap for the platform that standardizes it: authentication, authorization, routing, rate limiting and service onboarding. I also drive the migration off the legacy gateway, sequencing it so service teams switch over without disruption.
Result: One consistent way to expose, secure and operate APIs across the company, with access patterns like RBAC, entitlements and service-to-service auth aligned across teams.

Reporting API v2

Talent.com, Product Manager, 2021 to 2022

Problem: The reporting API had no rate limiting or load balancing. Some clients polled it like a real-time database, which took it down and left one of our largest clients with inaccurate, inconsistent numbers.
What I did: I championed and scoped a v2 reporting API built around rate limiting and load balancing, and helped write it.
Result: The outages stopped, the numbers became reliable, and we kept the client, recovering more than $10M in business within six months.

ATS integration architecture

Talent.com, Lead Product Manager, 2022 to 2024

Problem: Connecting enterprise clients on platforms like UKG and iCIMS took weeks, which capped how fast we could onboard.
What I did: I revamped the integration architecture for third-party applicant tracking systems.
Result: Integration time dropped from weeks to days, so the team could onboard far more enterprise clients.

Employer job posting experience

Talent.com, Lead Product Manager, 2022 to 2024

Problem: Employers needed a better way to post and manage jobs on the platform.
What I did: I built a new B2B job posting interface with Engineering and Design.
Result: Employer satisfaction rose 12% and new employer sign-ups grew 15%.

+12%employer satisfaction

neuvoo to Talent.com rebrand

Talent.com, Product Manager, 2021 to 2022

Problem: The whole product had to move to a new brand without putting client revenue at risk.
What I did: I led the transition, coordinating Product, Sales, Client Success and Finance, and kept six Scrum teams delivering through the migration.
Result: More than 1,000 client accounts moved over with zero revenue disruption.

1,000+accounts migrated, no revenue lost

Search and feed performance

Talent.com, Product Manager, 2021 to 2022

Problem: Job seekers weren't clicking through to apply often enough from our API and XML feeds.
What I did: I optimized how keywords and semantic search were matched in the feeds.
Result: Apply-click ratio went up 10%.

Publisher partnerships

Talent.com, Senior Partnerships Manager, 2019 to 2020

Problem: We were stuck spending around $150K a month to distribute our job listings to partner sites, because we didn't have enough publisher partners to put more budget to work.
What I did: I built strategic partnerships with publishers and job boards, sending our listings to them through XML feeds, and hired and trained the account team to run them.
Result: Monthly spend grew past $1.5M in under 8 months. With a 20% revenue share on every click, that meant more than $300K in monthly revenue, about $3.6M a year.

$300K+monthly revenue

About

I'm a Senior Product Manager II at Unity in Montréal, where I own Unity Gateway, the platform that decides how APIs across the company are exposed, secured and run.

Before that I spent six years at Talent.com, moving from building the publisher partner network into product. By the end I was Lead PM for B2B and Platform, managing three product managers and working as hands-on product owner across up to six Scrum teams, on systems from billing to publisher APIs.

I started in client success at Workopolis, where I led a team of eight across three cities, and I hold a Master of Arts in Human Systems Intervention from Concordia, a graduate program in organizational change and leading complex teams.

Going from HR tech to gaming infrastructure taught me that the craft is what travels: finding the real problem, getting many teams pointed the same way, and measuring whether it worked.
