Himanshu Rawat

Full Stack Developer

I solve complex problems by building scalable, maintainable web applications.

About

I’m a developer passionate about creating scalable, maintainable, and high-performance software solutions. I have experience in MERN Stack with TypeScript.

I am currently a Software Engineer at Xeno, where I have contributed to numerous projects. My work includes refactoring the Journey Builder product to adopt an event-driven architecture, cutting event delays from 24 hours to under 1 minute and improving UI/UX. I also led a small team to build Persona, an intelligent CRM platform that boosted customer engagement by 25% and revenue by ~10%. Additionally, I developed new Journeys features that increased product engagement by 45%, optimized frontend performance with a 30% reduction in load times, resolved all critical VAPT issues to strengthen security, and self-hosted Debezium and Kafka on Kubernetes, reducing cloud costs by 8–9%.

In the past, I’ve contributed at Focus Research Labs where I improved application efficiency, reduced server load, and accelerated query-lookup speeds by over 80% in the core framework.

Outside of coding, I enjoy watching anime, playing minecraft, strumming guitar and going to the gym. I’m always looking for new opportunities to learn and grow both as a developer and as a person.
