I've built AI-powered interview workflows at Virtual 2030, leading full-stack delivery with NestJS and Next.js. By integrating AI models into evaluation workflows, I helped reduce manual assessment time by 40%.

At IBlinkNext, I built Python and Flask stock and wastage engines that helped reduce wastage by 65% and increase sales by 30%. I also developed recipe and stock-consumption automation that improved pricing accuracy and contributed to a 40% profitability boost.

My work includes REST API integrations for UAE food marketplaces and healthcare providers, secure Keycloak authentication with SSO and MFA, and microservices for catalogs, meal rotation, and user profiles. I've also integrated Stripe payments and deployed Dockerized services on DigitalOcean with load balancing and auto-scaling.

I contribute to production systems across Python, NestJS, PostgreSQL, AWS, Docker, and Next.js. As an Expert Interview Engineer at Karat, I also evaluate coding, debugging, system design, and problem-solving across Python, Java, and JavaScript.
