Jeston Singh

I’m a Full Stack Software Engineer with 2+ years delivering production systems serving 10K+ users across fintech and healthcare domains. I focus on building scalable web platforms with React, Node.js, and microservices architecture.

I’ve led cross-functional teams of 8+ engineers, established CI/CD pipelines reducing deployment time by 60%, and implemented observability solutions cutting MTTR by 50%. I’ve also scaled systems to handle 10K+ requests/minute at 99.9% uptime.

In my recent role, I engineered production-grade web applications for 50K+ users with 99.8% uptime, improving responsiveness with React and React Native and reducing page load time by 45%. I built secure Node.js microservices with OAuth 2.0, rate limiting, and encryption, eliminating security incidents.

I also have AI/ML production experience from my Infosys internship, where I owned end-to-end ML systems with a 99.9% SLA and achieved <1 hour incident response. I’m proud to be a National hackathon winner (SIH & MSME) recognized for technical leadership and system design excellence.
