Harish Kumar
Full-Stack Architect
Specializing in high-performance SaaS platforms using React, Node.js, and AWS. I merge complex backend infrastructure with conversion-driven frontend execution to build production-grade systems that handle scale.
About Me
I am a results-obsessed Full-Stack Engineer focused on system architecture and measurable business impact. With nearly five years of intensive experience in high-growth environments, I specialize in bridging the gap between complex, scalable backend engineering and seamless, high-conversion user experiences.
My approach balances technical depth with business outcomes. At Pickyourtrail, I re-architected a high-scale booking flow to reduce friction, driving a verified 150% increase in conversion rates (driving significant revenue uplift). Prior to that, at Codedamn, I focused on heavy infrastructure optimization, utilizing container pipelines (Docker/Kubernetes) to slash AWS operational costs by 55% while improving uptime.
Beyond core responsibilities, I build complex distributed systems to stay on the bleeding edge. I architected Artemis (an AI OS leveraging RabbitMQ and Vector DBs for context awareness) and built WatchWithMe, a P2P streaming platform currently serving over 3,000 monthly active users with low-latency performance.
