What I'm looking for

I'm open to full-time roles, contracts, and long-term freelance partnerships. I’m looking for work where I can build applications, fix them properly, or scale them without downtime.

At OTELMS LTD., I led a rebuild of Kittrow’s authentication and security layer, including KYC onboarding and two-factor authentication. I also upgraded its Laravel backend across four major versions and migrated the frontend build tooling to Vite.

At Global Tech Network, I developed features for a compliance SaaS platform used by 300+ MSPs. I brought a policy management page from over five seconds to under one second, built an AI policy summarization feature using Llama, and implemented policy attestation signatures.

In freelance work, I created Akwantuo Express Ghana, a Laravel trip-management and booking application that increased user traffic by 30%. I also built a file management system with FastAPI, Redis, and Celery, deployed on Docker and DigitalOcean.

At Bewsys, I rebuilt a SaaS web application with Laravel PHP, improving efficiency by 30% by removing server-side React rendering. I work across Laravel and React, and use AI tools such as Claude as part of my development process.
