Sundaram Katare

I’m a full-stack developer who turns complex workflows into dependable software—especially when AI can remove repetitive manual effort. I build production-minded web platforms that connect data ingestion, verification, and user-facing experiences into one cohesive system.

In my recent Full Stack Developer role at Legion Automations, I developed an Accounts Payable verification platform that uses React/TypeScript, Node.js, and Supabase, integrating AWS Textract and Bedrock to automate OCR-based invoice extraction and PO validation—cutting manual data-entry time by 70%. I also built a Gmail API-driven ingestion pipeline with AWS Textract for real-time verification of supplier quantities, rates, and PO references, and created an AI-powered voice automation system with Retell AI, n8n, and GoHighLevel that reduced manual follow-up by 80%.

Earlier, as a Web Developer Intern at PHICSIT Infotech, I maintained a knowledge management platform on the MERN stack and improved admin workflow efficiency by 30% through secure authentication and RBAC with JWT. I’ve also shipped projects like FlowSpace, supporting 100+ concurrent users with low-latency Socket.io messaging and a task conversion feature (improving task creation efficiency by 30%), and Weave, an AI cover letter generator that reduced creation time by 95% while generating properly formatted 250-word letters.
