About

I build systems that hold under pressure and scale without apology. 5+ years shipping production software across fintech, blockchain, airport security, and SaaS. My work has directly contributed to $25M+ in enterprise contracts, $3M+ in platform revenue, and products used by 400K+ users across three continents. What I actually do: → Architect micro-frontend and microservices systems from scratch to deployment → Squeeze performance: reduced page load from 4.5s → 1.8s, cut code redundancy by 30%, improved deployment speed by 40% → Build resilient backends: Kafka, Redis, PostgreSQL, MongoDB, Node.js, FastAPI, Go → Lead teams: mentored junior engineers, led an 8-person dev squad on a live airport security platform used across Australia and Canada → Deliver SEO-ready, accessible UIs: lifted SEO scores from 35 → 90 across client products Tech I work in daily: React · Next.js · TypeScript · Node.js · Go · Python · Redis · Kafka · AWS · PostgreSQL · MongoDB Currently a Senior Software Engineer at EY, building enterprise-grade solutions. Open to high-impact Senior SWE opportunities where ownership, performance, and architecture actually matter. Let's talk: krishnakantmishra980@gmail.com | portfolio-kkrishna.vercel.app
