About

Professional summary

I am a Full Stack Software Engineer with 3 years of experience building multi-tenant enterprise SaaS platforms. I work across frontend, backend, databases, testing, and production deployments, with a focus on reliable business applications.

I build applications using React, Node.js, Python, TypeScript, and PostgreSQL. My backend experience includes Express.js, FastAPI, Flask, REST APIs, Prisma ORM, and scalable database access patterns.

I have delivered solutions for contract lifecycle management, invoice automation, inventory management, and commerce workflows. I have developed features for document authoring, approvals, metadata extraction, validation, version management, lifecycle tracking, and financial processes.

I have experience designing micro-frontend and microservices-based systems, including Vite Module Federation integrations with shared authentication, RBAC, and navigation. I also work with multi-tenant architectures and JWT-based authorization.

I build AI-assisted document processing and business automation workflows using Regex, NLP, vector search, and LLMs. My work includes invoice and contract extraction pipelines, human-in-the-loop validation, intent routing, and evidence-based AI agent applications.

I contribute to quality, performance, and deployment activities through automated testing, load testing, Docker-based deployments, Jenkins pipelines, NGINX configuration, and production troubleshooting.
