Mitul Rawat

I am an agile software developer with around 5 years of experience specializing in SaaS development using Python, Django, and FastAPI. I focus on building scalable backends and production-ready ML/NLP solutions for product-based environments.

At CallHub I designed and owned modules across Texts/Voice, NLP, CRM integrations, identification/compliance, media management and fraud detection, and implemented transcription with diarization and WebSockets using vLLM, llama.cpp and Redis for faster model inference. I led resiliency and performance projects that reduced page load times 3x, optimized Celery jobs for 5x efficiency gains, and redesigned bulk communication jobs to reduce database load by 20x.

I build resilient, plug-and-play product architectures to support rapid feature deployment, created dual push-pull setups for third-party integrations, implemented LoRAs for fraud detection and developed an AI agent for survey answering. Earlier I contributed to a lending platform and a doorstep fuel delivery solution as a Research Associate.

I hold an integrated B.Tech & M.Tech from IIT Roorkee, multiple programming curriculum certificates, and maintain small live apps demonstrating RAG and cloud texting tools. I enjoy solving product problems, learning new ML inference techniques, and contributing to high-impact, collaborative teams.
