What I'm looking for

I'm looking to build secure, reliable web products in collaborative Agile teams, contributing across React/Vue front ends, APIs, and backend services while continuing to improve performance, security, and system reliability.

At TalkRemit, I build fintech products across Symfony backend services, React and Next.js front ends, and RESTful integrations with Java-based microservices and third-party financial services. I improve Core Web Vitals through code splitting, lazy loading, and asset optimisation while applying XSS/CSRF protection, input validation, and secure token handling.

I've also delivered React, Vue.js, Next.js, and Nuxt.js payment products at Grow Mobile Technology and Binary Pay, including reliable Redux Toolkit workflows and Cypress-tested API-connected components. As the sole developer for geraldlangiri.com, I built a React/Next.js portfolio with a custom admin CMS and casting-call submission workflow, and I mentor developers in React and web fundamentals.
