Rani S.

I build production software that businesses actually run on — custom SaaS platforms, ERPNext implementations, and the AWS infrastructure underneath them. I'm the founder and lead engineer of a team of engineers and an AWS Partner, and I bring that same hands-on team to Upwork. What I do: - Custom SaaS — React, Next.js, TypeScript, Node.js/Python backends, plus the payments, auth, analytics, and third-party APIs that make it real. Built a multi-tenant F&B ordering platform now running across 150 cafe. - ERPNext implementation — custom modules built around how your industry actually operates, full data migration, and hands-on department-by-department training. Recently delivered ERP for a 200+ employee manufacturer and a multi-branch hypermarket. - AWS Cloud & DevOps — architecture, migration, cost optimization, Docker/Kubernetes, CI/CD, and ongoing monitoring of performance, security, and spend. - AI integrations — computer vision, AI agents, and automation embedded into real workflows with dashboards and alerts, so they keep improving after launch. Security-conscious by default (Google Cybersecurity certified). I work in fixed sprints that each end in a working demo, you're the single point of contact throughout, and you own the code, infrastructure, and documentation. I stay on after launch. Tell me the problem, not the spec — I'll come back with an approach, a timeline, and a number.
