Services | Brian Chirchir - Senior Product Manager

Services

Product leadership for teams building under real constraints.

I work with organisations that need senior product thinking without adding ceremony for its own sake: discovery, strategy, specifications, stakeholder alignment, and delivery oversight for products where trust, infrastructure, and adoption decide the outcome.

2-8 week discovery or delivery sprint

Product Management Consulting

End-to-end product ownership for teams building in fintech, civic tech, SaaS, edtech, and emerging-market infrastructure. I help frame the problem, align stakeholders, define the delivery path, and keep execution connected to real user constraints.

1-4 week architecture and product review

Fintech Service and Payment Systems Product Strategy

Integration design, reconciliation logic, payment journey review, and product strategy for teams building around fintech services or adjacent mobile money ecosystems. Useful when trust, idempotency, delayed callbacks, and field realities matter as much as the happy path.

2-6 week research engagement

Product Discovery and User Research

Human-centred discovery for low-bandwidth, infrastructure-constrained, or high-trust environments. I run constraint mapping, user interviews, field synthesis, and decision-ready product recommendations.

1-3 week specification package

Technical Product Specification

PRDs, user stories, acceptance criteria, UAT runbooks, and development handoff documentation for organisations that need senior product thinking before or alongside engineering delivery.

2-5 week scoping sprint

AI Product Strategy

Practical AI product scoping grounded in delivery experience from WealthTrack, YodaAI, and BizFramer. I help teams identify where AI creates usable leverage, where rules still matter, and what needs to be measured before launch.

Engagements

Useful when the work is too important to stay vague.

The best fit is a team with a real product problem, a complex operating environment, and a need for clear product judgement across business, users, and engineering.
