About

I build the UIs that security analysts trust to stop attacks in real time. Right now, I'm a Software Development Engineer – UI at Trellix, working in the cybersecurity space. My focus: making complex, data-heavy interfaces fast, reliable, and human — the kind where engineers don't second-guess what they're seeing when it matters most. Here's what I've shipped recently: → Resolved a production-blocking MFE integration issue that was holding back the entire release pipeline. → Designed a dynamic micro-frontend architecture that cut onboarding time for new apps by 40%. → Built real-time dashboards using WebSockets for live security event feeds — reducing UI lag by 25–30%. Before Trellix, I spent 2+ years at Persistent Systems building enterprise SaaS products — including a Microsoft Teams chatbot used daily by 20,000+ employees. I also built complex no-code workflow UIs in React Flow, avoiding paid third-party licensing by extending it with custom canvas interactions. At eGain, I shipped an AI-powered article generation system with RBAC for enterprise clients including IRS and JPMorgan Chase — cutting manual content creation time by up to 50%. What I'm good at: ⚙ React + TypeScript at scale ⚙ Micro-frontend architecture ⚙ Real-time systems (WebSockets, live data) ⚙ Performance optimization for data-heavy dashboards ⚙ AWS (ECS, ECR, ALB), Docker, CI/CD I'm based in Bengaluru and open to senior frontend / staff-level roles at companies where frontend quality is taken seriously. 📩 DM me or email: nirajdasari.dev@gmail.com
