I’m a Backend Engineer with 1+ year of production experience building systems that handle real users at real scale—from a national government platform with 1M+ users to an ERP managing 12,000+ students. I choose the right tool for the job and stay focused on reliable, maintainable backend delivery.

At Creative IT Park, I built SLS, a school ERP serving 12,000+ students across 8 role-based portals, covering the full student lifecycle, fee/challan generation, attendance, exam grading, and financial audit reports. I also built Hello Creative IT Portal (CRM/ERP) to run HR workflows, Kanban deal pipelines, Gantt project tracking, invoicing, and double-entry accounting (P&L, balance sheet, ledger).

I own server operations end-to-end—Linux/cPanel provisioning, SSL/DNS, environment separation, DB migrations, and production monitoring—maintaining ≥99% uptime. I standardize deployments (staging → production, rollback procedures, health checks), cutting production incidents significantly, while containerizing services with Docker and deploying to AWS.

Previously, I delivered the production backend for BuzzMap (real-time event discovery) using Node.js/Express, MongoDB, Redis, and WebSockets, including geolocation APIs, OAuth 2.0 auth, rate limiting, and structured error handling for US production standards. I also built 15+ React/Redux components that improved page load performance by 25% for 100,000+ active users, and I’m comfortable collaborating in remote async teams and contributing across the stack when needed.
