What I'm looking for

I’m looking for a backend-focused role where I can own end-to-end features, build scalable APIs and real-time systems, and improve performance with clean architecture. I want Agile collaboration, code review culture, and room to grow through mentoring and DevOps-minded delivery.

I’m a Backend Developer with 3+ years of hands-on experience shipping production systems with Python, Django, FastAPI, and Laravel. I specialize in scalable REST APIs, real-time WebSocket systems, Redis-powered workflows, and clean database architecture.

At Inlancer Technologies, I architected and maintained backend services that serve thousands of active users daily with consistent uptime. I reduced average API response time by 30% using MySQL query optimization, strategic indexing, and Redis caching, and I migrated real-time notifications from polling to WebSockets (Django Channels) to improve delivery speed while cutting server load.

I also built a WhatsApp messaging system handling 2,000–3,000 messages/day using Redis pub/sub and queues, achieving 60–70% delivery and 80–90% response rates. I integrate Stripe and Razorpay with webhook-based event handling, deploy on DigitalOcean, and explore containerized deployments with Docker/Kubernetes and Jenkins CI/CD in a self-directed AWS lab—while owning problems end-to-end, mentoring junior developers, and collaborating in Agile environments.
