What I'm looking for

I’m looking for a role where I can build full-stack products and APIs, maintain and integrate systems, and apply solid architecture and optimization. I value collaboration, clear ownership, and measurable impact on performance and efficiency.

I’m a full-stack developer who enhances productivity and efficiency through strong algorithm design, system architecture, and code optimization. I thrive on solving complex problems and collaborating effectively to deliver reliable outcomes.

At Mwalimu National Sacco, I rejoined for development and system maintenance on the Dynamics Significant Capital system, plus the development of an Inventory System for Child Hope Foundation. I also developed and built systems including Voting, Fleet, Auditing, Investments, and Member Management/registration, using React/TS/JS, NextJS, MongoDB, Express, and PostgreSQL.

I’ve supported Dynamics Business Central maintenance and performed MSSQL database integration with Dynamics Business Central. Alongside this, my earlier data and document management experience strengthened my data entry accuracy, confidentiality, and quality-check habits—skills I bring into every build and deployment.
