Fig. 1.1 — kenya.psms.africaThe live public reporting portal, captured October 2026. Portal statistics are cropped out.
A full-stack public-safety platform for police services, bringing occurrence reporting, investigations, case management, assignments, analytics and command dashboards into one system.
Role
Founder / Software Engineer
Where it stands
In development. The public reporting portal is live at kenya.psms.africa.
What I did
AI-assisted workflows for case analysis, grounded summaries, report intelligence and decision support.
Production-oriented foundation: automated testing, secure connectivity, notifications and a Turborepo/Yarn monorepo.
Next.js and Relay over a .NET 8 / HotChocolate GraphQL API, with Entity Framework Core and PostgreSQL.
Azure Front Door Premium, WAF and private connectivity, with Keycloak for identity.
A conceptual view of the scope described above — one shared reasoning experience serving first- and third-party agents across four Microsoft 365 surfaces. Not an internal architecture diagram.

about 4 s
After

Over 60% faster, measured with the Browser Performance API.
Standardising how LLM reasoning is presented across Microsoft 365 Copilot agents — for first- and third-party agents, in Teams, Outlook, Word and PowerPoint.
Role
Initiated and led the engineering effort. Primary engineering owner, later co-lead as the effort scaled.
Where it stands
Taken from early architecture through general availability.
What I did
Scaled the shared reasoning experience across Teams, Outlook, Word and PowerPoint, for first- and third-party agents.
Built reusable platform frameworks and developer abstractions: plug-and-play APIs, reusable components, agentic workflow abstractions.
Authored specs and cross-team architecture guidance: service-client contracts, message consistency, rollout dependencies, production blockers.
Designed product telemetry (engagement, latency, dwell time, step interactions) that informed staged rollout and GA decisions.
Established Playwright-based end-to-end regression coverage.

Kenya · Nigeria · Zimbabwe
Backend engineering for Kenya Power's revenue collection and customer systems — migrating legacy debt, integrating payments and keeping prepayment requests resilient.
Role
Backend Engineer for client Kenya Power & Lighting Company (KPLC). Led the Interfaces Module (Indra InCMS to third-party systems).
What I did
Built a middleware application to migrate USD 5M+ of legacy debt to a microservices architecture.
Built a resilient microservice for failed prepayment API requests (Itron), used in Kenya, Nigeria and Zimbabwe.
Integrated card-present payment capabilities into the revenue collection system.
Redesigned the customer onboarding and self-service flow for tenancy accounts.

How I work
My work spans Microsoft 365 product and service-integration engineering, reusable AI-agent architecture, and cross-product platform capabilities, with a focus on scalable frontend systems and LLM-powered experiences.
01
Own the whole arc
I take ambiguous, cross-team initiatives from first architecture through production adoption and general availability.
Evidence Initiated the effort to standardise LLM reasoning UX across Microsoft 365 Copilot agents — primary engineering owner, later co-lead as it scaled.
02
Build the platform, not the one-off
I favour reusable frameworks, components and APIs that other teams can build on.
Evidence Plug-and-play APIs, reusable components and agentic workflow abstractions for the Microsoft 365 AI-agent ecosystem.
03
Measure, then decide
I instrument what I ship, so rollout and performance decisions rest on evidence.
Evidence Telemetry on engagement, latency, dwell time and step interactions informed staged rollout and GA; Browser Performance API measurement behind a 60%+ faster load.
04
Align in writing
I put contracts, dependencies and risks on paper early, where every team can see them.
Evidence Authored specs and guidance on service-client contracts, message consistency, rollout dependencies and production blockers.
05
Grow the people around me
I invest in the engineers and educators who come next.
Evidence Mentored five engineering interns; led AI and software-engineering upskilling for Kenyan university lecturers; contributed to curriculum reviews.
