Software Engineer
Software Engineer with 4 years of experience across enterprise banking systems and startup client work.
I work in short cycles. At Optima I demoed progress to government and NGO stakeholders, so I got used to taking feedback from a demo and turning it into the next delivery.
That habit made switching stacks normal. In four years I have worked in Vue, React, Flutter, Next.js, WordPress, and Supabase, learning whatever the project needed, including payment integration with Stripe.
At Bank Raya I develop internal systems for several bank divisions, peer reviewing with teammates as we ship, and on the side I take international client work on Upwork, reading unfamiliar code and refactoring AI generated code until it runs.
