About Me

The Architect Behind the Code
Malhar - Systems Architect

Bridging the Gap Between Code and Physical Infrastructure.

Hi, I’m Malhar. I am an independent Systems Architect and Full-Stack Engineer based in Mumbai. I don't just write code; I build end-to-end ecosystems. From engineering ultra-low-latency backend architectures for multi-broker trading platforms to deploying physical fiber-optic ISP networks and custom hardware automation systems, I specialize in solving complex business problems at scale.

  • Security First: Obsessive about network lockdowns, reverse proxies, and data integrity.
  • Business-Centric: Designing systems that directly drive revenue, streamline client onboarding, and handle production workloads.
  • Full-Spectrum: Comfortable navigating React frontend animations, Spring Boot microservices, and Arduino circuit logic all in the same day.
