What I'm looking for

I'm open to remote and local roles, full-time or contract, and can start immediately.

At ASTRA TECH, I built and shipped a production platform where Ugandan schools register, submit SchoolPay codes, and upload marksheets for digital report cards. I implemented the responsive React frontend, secure uploads, admin dashboard, and automated onboarding emails.

For a school outreach system, I compiled a verified database of 274 institutions and delivered personalized emails through the Gmail API with pacing and retry logic. I added DNS/MX validation and live Google Sheets reporting so the owner could track outreach without using a database.

In freelance and client engagements, I deliver web applications and automation from requirements through deployment. I also delivered an AI operations assistant that works with Gmail, Google Sheets, and Google Calendar, runs scheduled workflows, and reports to the owner on WhatsApp.
