Software Engineer @ Visa \| Applied AI · Full Stack

## About

I'm a software engineer at Visa building production platforms at the intersection of AI infrastructure and distributed systems\. In my first year, I independently designed and shipped three full platforms from scratch — covering everything from async task queues and fleet management APIs to LangGraph\-based AI pipelines and LLM evaluation systems\. What I've built at Visa: → An internal developer platform that automates the full lifecycle of deploying and managing AI agents across the organisation\. Reduced onboarding time by 10x and scaled to manage hundreds of agents and repositories in production\. → The backend for an internal AI code generation platform that takes design inputs and produces production\-ready UI components\. Built the human\-in\-the\-loop feedback agent on LangGraph, monorepo support, and the full analytics pipeline \(FastAPI \+ PostgreSQL \+ React dashboard\)\. → A conversational AI data service where I replaced a legacy entity resolver with a 5\-layer cascade combining exact SQL, pgvector semantic search, trigram fuzzy matching, and LLM fallback\. Query accuracy improved from \~40% to 89%\. Also built the async execution infrastructure and the first automated quality evaluation service for the platform\. Stack: Python · FastAPI · LangGraph · asyncio · TypeScript · React · Node\.js · PostgreSQL · pgvector · Docker · Anthropic API Strongest angles: end\-to\-end product ownership · takes a problem from zero to production · works well under ambiguity · full\-stack execution · AI/LLM systems

## Work experience

Software Engineer at Visa, Jun 2025 \- Present · 1 yr 4 mos, Bengaluru, Karnataka, India, Building production systems across applied AI, full\-stack engineering, and automation at Visa\. Conversational AI Data Service \(Jun–Jul 2026\) \- Replaced a legacy entity resolver with a 5\-layer cascade \(exact SQL, semantic search via pgvector, fuzzy match, LLM fallback\)\. Accuracy improved from \~40% to 89%\. \- Built async execution infrastructure eliminating gateway timeouts on long\-running queries\. \- Built an automated LLM\-based quality evaluation service, full stack \(FastAPI \+ PostgreSQL \+ React\), from scratch, in 28 days\. Agent Onboarding & Fleet Management Platform \(Jan–Jul 2026\) \- Founding engineer, built from scratch\. 228 APIs, 29 scheduler state machines, 193 React components\. Manages hundreds of AI agents in production\. \- Reduced onboarding time by 10x through end\-to\-end automation\. Owned the architecture, the build, and the rollout\. \- Automated fleet\-wide operations \(image rotation, config updates, credential management\) replacing manual workflows\. AI Code Generation Platform \(Aug 2025–Jan 2026\) \- Built the entire backend from scratch for an internal Figma\-to\-UI AI system \(Node\.js, LangGraph, FastAPI\)\. \- Built the human\-in\-the\-loop feedback agent\. Users refine AI\-generated components iteratively without restarting the pipeline\. \- Drove adoption across 5 engineering teams\. Expanded test coverage from 26% to 84%\.
