Competitve Coding | Backend Development | Devops
Hi, I'm Charchit Gangwar
Engineering Integrated and Automated Solutions for Modern, Scalable Applications.
I'm a developer who likes building automations and integrations that take messy, manual workflows and turn them into reliable, automated systems.
Across two SDE internships, I've built event-driven backends connecting six developer ecosystems, automated WhatsApp messaging stacks against the Meta API, and shipped lead-management products that capture activity entire meta-suite (Whatsapp, facebook, Instagram) end-to-end.
On the side I've engineered a 3-stage RAG pipeline that dissects massive GitHub codebases, built a unified university ecosystem with JWT identity and automated payment + notification pipelines, and put together ML-driven analysis frameworks. I back that with 1000+ DSA problems and am currently leveling up in Go, AWS, and DevOps.
