About Me
Software Engineer & Full Stack Developer passionate about designing scalable systems and solving real business problems.
Hi, I'm Divyanshu Srivastava — a Software Engineer & Full Stack Developer at BOT Mantra, based in Bengaluru, India. I specialize in designing and delivering scalable, production-ready applications that solve real-world business challenges.
Over the past few years, I've worked across the full stack using Python (FastAPI), React, TypeScript, PostgreSQL, and Azure. My experience spans backend architecture, secure authentication, real-time WebSocket applications, intelligent document processing pipelines, and cloud-native deployments.
"I enjoy owning products end-to-end — from understanding complex business requirements and designing resilient systems to development, cloud deployment, and production support."

Beyond Engineering & Code ⚽🎮🕺
Outside of development, you'll probably find me playing football, dancing, or grinding Valorant and FIFA. If I'm not designing systems, there's a good chance I'm either clutching a 1v3 in Valorant or trying to score a last-minute winner in FIFA!
Football ⚽
Love playing on the pitch and following tactical football strategy.
Esports & Gaming 🎮
Grinding Valorant (clutching 1v3s) or scoring last-minute winners in EA Sports FIFA.
Dancing 🕺
Unwinding with rhythm, dance, and music outside of system design.
