What I'm looking for

I seek a role building scalable full‑stack or backend systems with strong DevOps practices, collaborative teams, and opportunities to optimize production deployments.

I am a results-driven Software Engineer with 2+ years of experience building full‑stack applications, backend APIs, and managing Linux-based production infrastructure. I specialize in Flutter mobile development, Node.js RESTful APIs, containerization with Docker, and CI/CD automation.

At Grip INT PVT LTD I designed and deployed containerized backend services, optimized Nginx/Apache configurations to improve response times by 40%, and maintained Linux servers to achieve 99.9% uptime. I also developed secure authentication systems, implemented load balancing and PM2 process management, and administered databases including MySQL and Microsoft SQL Server.

I collaborate closely with cross-functional teams, mentor junior developers, and produce clear technical documentation. I prioritize secure, maintainable, and performant solutions across the entire application lifecycle, from development through production deployment.
