What I'm looking for

I'm looking to build scalable full-stack products, improve frontend performance and reliability, and contribute to microservices, cloud deployment, automation, and end-to-end user workflows.

I built scalable job portal workflows at Jobox Hire, including applications, hiring, interview scheduling, real-time communication, payments, geolocation, AWS S3, and push notifications.

I've improved frontend rendering performance and scalability by 35% using code splitting, lazy loading, memoization, virtualization, and optimized state management across React.js, Next.js, TypeScript, Redux Toolkit, and React Query.

At Synechron, I delivered scalable frontend workflows and API integrations in a microservices architecture while building Playwright automation frameworks with cross-browser testing, API mocking, parallel execution, and CI-integrated pipelines. I've also developed fintech OCR document-processing and reporting products, plus a Vastu consultation platform with booking, payments, WebRTC video consultations, and ticketing.
