What I'm looking for

I’m looking for a team where I can ship end-to-end features across web and mobile, collaborate in an agile workflow, and build high-performance APIs and UX-focused interfaces from design to deployment.

I’m a full-stack developer specializing in front-end delivery and mobile features, with hands-on experience building across mobile, web, and backend in an agile team. I focus on pixel-perfect implementation from Figma, responsive UI, and global state management to keep performance and UX consistently high.

On the backend, I design RESTful APIs with Express.js and MongoDB, add caching and async workflows (Redis, cron jobs, RabbitMQ), and optimize search using MongoDB Atlas $search with fuzzy matching and indexing. I also ship user-facing products like onboarding tours, social story feeds, search experiences, and admin dashboards—always aiming for measurable improvements in engagement and usability.
