At Tinkerbox Studios, I lead development of an enterprise SaaS platform, delivering frontend and backend features for business-critical systems used by international clients. I developed React and Next.js dashboards and customer portals, improving page load time by approximately 20% through component optimization and state management improvements.

I also implemented secure authentication services with Node.js and NestJS, including JWT authentication and role-based access control. I optimized MongoDB aggregation pipelines and caching strategies to improve API response efficiency and reduce dashboard data retrieval latency.

At Codigo, I developed and maintained a high-traffic e-commerce platform with product listings, cart systems, order management, and payment integration. I built backend APIs and GraphQL services, and optimized rendering, image loading, and database queries to improve page load and search performance by approximately 15–20%.

Earlier, as a Frontend Engineer at Snappymob, I developed responsive web applications and Next.js SSR experiences, improving initial page load performance by approximately 20%. I’ve worked with distributed teams in Agile environments and have experience across frontend development, backend services, and cloud deployment.
