# Jayakrishnan V R on Tal

## Headline

Full Stack Engineer \| FastAPI, React, PostgreSQL \| Scalable SaaS & data\-driven applications

## About

I build backend systems and full\-stack applications for SaaS products, with a focus on API design, database architecture, and reliability at scale\. Over the past 4\+ years, I've worked across the stack, designing PostgreSQL schemas for complex relational data, building FastAPI\-based services shipping React/Next\.js frontends used by 50\+ clients companies\. At Hexafort, I've been part of the core team evolving a GRC platform into a suite of modern SaaS products, contributing to 40% reduction in report processing time\. Before this, at EY, I built backend systems that automated tax and profitability calculations from client\-uploaded Excel data, reducing manual processing time by 80% for a team handling 20\+ clients having 40\+ files each\. Outside client work, I build and maintain Insight Node, a self\-directed observability platform inspired by Datadog, using Python and FastAPI, because I like understanding systems from the infrastructure layer up, not just the application layer\. Originally trained in Physics before moving into computer science \(MCA\), I bring a systems\-first, first\-principles approach to engineering problems\.
