At SunDevs LLC, I designed and built an end-to-end role-based access control module for ~200 users, with multi-scope permissions and environment isolation. I used React 19, TypeScript, NestJS, and MongoDB, and optimized queries to address pagination and concurrency issues.
At Assist S.A., I cut application load times by ~40% and reduced data wait times from ~4 seconds to ~1 second by improving API consumption and data fetching. I introduced TanStack Query for caching and consistent loading and error states.
At Alternova Tech, I strengthened application security with Content Security Policy and two-factor authentication to meet external audit requirements. I also build web apps through freelance and personal projects, including LLM-powered chatbot interfaces.
