- PMI-ACP, PSPO I, PSM I
Selected case studies
Regulated workflows, design systems and 0-to-1 products. Three in depth, with the discovery, the trade-offs and the decisions that did not survive delivery.
As Product Manager across three engineering squads: a 14-step climate-target validation workflow taken down to 6 steps, on an enterprise platform processing targets from thousands of companies worldwide.
Founder-owned 0-to-1 product for Europe's lost-and-found ecosystem. I set the MVP scope against one question, what is the minimum viable trust, and the KPI framework the platform runs on. Matching, three-stage verification and partner workflows, across B2C and B2B.
A 60+ component system built from scratch for a global climate-tech platform. It unified three product squads, and engineers moved to pulling components by name instead of rebuilding them per screen.
An independent product where I own the roadmap and the release decisions, taken to functional builds with AI-assisted tooling so the scope is tested against real platform constraints rather than a static prototype.

How I work
I am a Product Manager and Product Owner with 9 years building digital products across B2B SaaS, climate tech, fintech, payments and consumer apps, with a background in senior product design.
Where I do my strongest work
Complex products where people read dense data, complete regulated workflows, or make decisions that are costly to reverse. I work from user problem to release: discovery, problem framing, roadmap shaping, prioritisation, requirements and acceptance criteria, sprint delivery, then the metrics and the iteration after launch.
What the design background adds
I write requirements that survive contact with engineering because I have sat on the other side of them. I can define a flow, test it with users, and take it to a functional build in React and TypeScript using AI-assisted development. Anstoss went to Android and iOS this way. Real product behaviour surfaces the problems a document hides, before implementation gets expensive.

What the people I worked with say
Recommendations from people I worked with, with the working relationship stated. Excerpts are verbatim and uncut except for length.
“Opeyemi has strong product judgement and a clear ability to turn complex problems into practical product decisions. He works effectively across engineering, design, and stakeholders, brings structure to ambiguity, and keeps teams focused on the priorities that deliver the most value. He combines a strong understanding of user needs with technical awareness and takes genuine ownership from problem definition through delivery.”
“Opeyemi has a quick understanding and has the ability to adapt functions and patterns across different screen flows effectively.”
“He combines an innate understanding of user needs with business goals, creating intuitive and visually compelling designs.”
“A professional who stands out with his ability to translate intricate user and business needs into intuitive and meaningful designs.”
