Hi, I'm
Ayush Kumar.
I build production systems that scale — from OCR microservices and event-driven pipelines to real-time mobile apps. Currently at NexoGrafix. Open to my next challenge.
Engineering & Strategy
I'm a Full Stack Engineer based in Patna, India, currently building DocStreamat NexoGrafix — a document conversion platform (OCR → XML → EPUB) in a microservices architecture using FastAPI, React, and RabbitMQ. I specialize in data structures, API design, and performance tuning.
I hold an MBA in Marketing alongside my engineering background. That unique combination means I can architect a Celery worker queue AND write the PRD for why it needs to exist.
Previously at ShipU Logistics and Shabra Softech, where I shipped production systems, migrated a legacy monolith to a Turborepo monorepo, and helped serve 1,000+ monthly active users.
