What I'm looking for

I’m looking to build scalable Python/Django and Frappe/ERPNext backend systems—optimizing performance, security, and reliability—while working on real-time, multi-tenant architectures with a quality-driven team.

I’m a backend-focused full stack developer with 4+ years of experience building scalable, production-grade systems using Python, Django, and the Frappe ecosystem. I specialize in ERPNext customization, multi-tenant architectures, and high-performance backend systems.

At KAS Mentor, I optimized system performance by reducing latency up to 50% through database query improvements and Redis-based caching. I also built real-time API layers and integrated React using Frappe-React-SDK to improve engagement by 20%, while implementing secure ERPNext financial workflows and improving reliability with structured logging, error handling, and monitoring.

I’ve delivered enterprise-ready features by customizing and extending ERPNext modules, refactoring legacy code to reduce technical debt, and leading end-to-end development of a real-time analytics dashboard with Django. I bring an AI-assisted development workflow mindset—using Copilot/LLM tools while maintaining strict standards for security, performance, and code quality.
