What I'm looking for

I seek roles building user-centered web platforms with strong backend integrations, collaborative Agile teams, opportunities to work on payments or cloud deployments, and pathways for technical growth and impact.

I am a full-stack software engineer with hands-on experience building user-focused applications using Python (Django), JavaScript (React, Next.js) and Ruby on Rails. I have led development efforts across payment automation, invoicing, and platform integrations, delivering scalable solutions on Google Cloud Platform and implementing CI/CD pipelines to ensure high availability.

I collaborate closely with stakeholders to translate user feedback into precise technical requirements, improve usability through iterative testing, and automate complex workflows to reduce manual errors. My work includes integrating M-PESA payment flows, designing secure APIs with JWT authentication, and building responsive front ends with Next.js and Tailwind CSS.
