Bringing proven continuous-delivery practices to the Home & Fibre engineering team.

• Helping the team raise delivery throughput by introducing the continuous-delivery practices proven on earlier platforms — blue-green deployments, feature flagging and automated pull-request testing.
• Partnering with frontend and backend engineers to streamline the release pipeline toward a predictable, repeatable delivery cadence.
• Contributing across the stack and sharing delivery practices through mentoring.

DigiFarm Buyer Portal — connecting produce buyers with smallholder farmers, with quality-based payments and farmer-collection management.

• Built and shipped the Buyer Portal MVP, owning the full frontend through first release and contributing backend microservices alongside the backend team.
• Designed and rolled out blue-green deployment environments with DevOps, removing environment contention between development, QA and security and enabling near-continuous delivery.
• Introduced feature flagging across the codebase so each change could be released independently and targeted to selected UAT or production users — reducing release risk and unblocking parallel work.
• Co-created a build-promotion pipeline that builds a Docker image once and promotes the same artifact through every environment, and added ephemeral preview environments with Playwright automation to GitLab merge requests.
• Served as onboarding lead for new engineers — mentoring joiners, running code and design reviews, and owning the team’s engineering documentation.
• Helped stand up a self-hosted Langfuse instance to manage and observe prompts for the team’s AI chatbot, supporting an AI-assisted product workflow with LangChain and LangGraph.
• Together, these practices supported a weekly feature cadence and contributed to DigiFarm reaching operational break-even and securing renewed board funding.

Architecting the integration layer that modernised the bank’s digital channels.

• Architected an integration middleware layer that decoupled the bank’s mobile and web clients from legacy core-banking and internet-banking APIs — enabling modern app development without altering a contractually frozen legacy codebase.
• Built the layer in Node.js with Redis as a caching and tokenization store for authentication sessions, replacing server-rendered jQuery pages with clean REST services consumed directly by client applications.
• Established a reusable platform foundation the bank has continued to build on — including the Yea youth-banking app, pioneered during the engagement, and the rebuilt MCo-op Cash Android application.
• Contributed to delivery of the KCEP digital platform supporting county-government entities.
• Partnered with QA and security to introduce automated testing into the codebase, improving release stability and cutting regression defects by roughly half.

Card-payments and point-of-sale technology — where my backend journey began.

• Began my career building backend services, developing reporting microservices that improved accounting-team throughput during month-end and invoice-generation peaks.
• Built an SMS notification microservice for rider-SACCO payment reminders, improving payment-response and revenue-collection rates.
• Contributed frontend and operational improvements to the ride-hailing platform, supporting steady growth in active usage.

Intensive training, then delivering outsourced software for global clients.

• Completed Andela’s intensive software-engineering program and joined the apprenticeship delivering outsourced software for international clients.
• Served as team captain for a group of junior developers, coordinating delivery, quality and morale — an early grounding in technical leadership.
