Deepak kumar

I’m a Backend Engineer with freelance experience building production-grade web applications and Generative AI-powered systems for real business clients. I combine strong problem-solving with leadership and an entrepreneurial mindset, and I’m comfortable working remotely or on-site with international teams.

In my current role, I shipped a multi-system dental clinic platform with WhatsApp Business API integration and an AI chatbot for automated patient queries, appointment booking, and follow-ups. I also delivered a productized deployment model that reduced new client onboarding to under 2 hours via single config updates, while maintaining 100% uptime across Vercel deployments.

I’ve built backend systems that directly solve user needs, including a job portal connecting Bihar students and job seekers with verified employment opportunities in Pune. Alongside engineering, I provide end-to-end technical support (Tier 1/2), perform high-accuracy data entry and CRM management (200+ leads with 99%+ accuracy), and develop tools like a full-featured CRM with role-based access control and JWT authentication.
