## About

GenAI Engineer at CodeSage, building LLM\-powered products end\-to\-end — from the RAG pipeline to the React UI — with 6\+ years of prior full\-stack experience grounding me in what it takes to ship these systems to real users\. Currently on\-site at a Bengaluru\-based nonprofit client, working on an AI discovery assistant with web and WhatsApp interfaces, multilingual across 9 Indian languages in text and voice, held to a WCAG\-AA bar with AAA on core surfaces\. What I work on day to day: • LLM apps — Qdrant vector search, Ollama embeddings, LLM\-as\-a\-Judge confidence scoring, prompt engineering, evals • Grounded answers — the systems I build decline when the corpus doesn't hold an answer rather than inventing a citation; built a second assistant over a community voice archive on exactly that principle • Re\-architecture — provider gateways that remove single points of failure, identity\-gateway auth, parity harnesses that prove a rebuild matches what it replaced • Production ownership — incident RCAs, load testing, restore\-verified cutover backups, and the readiness planning that stops the same class of failure recurring • Full\-stack delivery — React \+ NestJS \+ Python services, OTP/auth, admin portals for chunk & metadata management • Offline\-first mobile — Android and desktop apps for field officers with no reliable connectivity: local mirror, sync conflict resolution, honest sync states • Accessibility\-first UI throughout Previously: 6\+ years as Senior Software Engineer / React Developer at Azilen, NinjaTech, DataNova, Webelight, and IIH Global — leading frontend architecture for SaaS platforms, mentoring engineers, and shipping performance\-optimised React \+ React Native apps\. Open to GenAI Engineer, AI Engineer, and Full Stack \+ AI roles\. Based in Bengaluru\.

## Work experience

GenAI Engineer at CodeSage India Private Limited, Feb 2026 \- Present · 8 mos, Bengaluru, GenAI Engineer building an LLM\-powered discovery assistant and an offline\-first Monitoring/Evaluation platform for a Bengaluru\-based nonprofit client\. On\-site, two workstreams\. • RAG \+ LLM assistant — Python retrieval service \(Qdrant vector DB, Ollama embeddings\), LLM\-as\-a\-Judge confidence scoring, chunk/metadata admin portal\. Stack: React, NestJS, Python\. • v2 re\-architecture — provider gateway removing a single point of failure, identity\-gateway auth, a 414\-case parity harness proving the rebuilt answer core matched what it replaced, Redis state layer, SSE streaming\. • Grounded answers — deterministic disclosure when the corpus holds no answer, citation hygiene, dead\-domain link suppression; it declines rather than inventing a source\. Built a second assistant over the client's voice archive on the same principle, prototype to demo in four days\. • Production ownership — root\-caused and fixed two user\-blocking incidents \(per\-IP throttling that locked out every WhatsApp user; a trust\-proxy misconfiguration that collapsed every client IP\), then wrote the readiness plan for the shared cause\. Load\-tested the WhatsApp webhook on an isolated prod\-parity instance; restore\-verified cutover backups and rollback plan\. • Test engineering — a 129\-case auth suite that proved a session cookie outliving its JWT by 168x under production config, invisible on staging\. • WhatsApp bot \+ web app — Meta webhook integration, feedback loop, 9 Indian languages in text and voice\. • Auth & communications — email \+ SMS service built from scratch in NestJS; OTP, UUID reset tokens in Redis, role\-based access\. • Offline\-first mobile & desktop — Android and desktop \(Tauri\) for field officers in low\-connectivity areas: role\-scoped local mirror, sync conflict resolution, resumable pull, signed releases\. • Accessibility — WCAG\-AA across the product, AAA on core surfaces; 50\+ issues resolved with a11y QA\. • Platform — migrated production ingestion to Vertex AI; LiteLLM for token/cost observability\.

Senior Full Stack Engineer at DataNova, Aug 2025 \- Dec 2025 · 5 mos, Ahmedabad, Senior Full Stack Engineer on a 5\-month engagement focused on building and scaling React\-based web applications with a REST API backend\. • Shipped production React features with a focus on clean component architecture, state management, and rendering performance\. • Designed and integrated REST APIs; collaborated on contract design with backend engineers\. • Drove code quality through reviews, consistent patterns, and performance profiling on high\-traffic UI flows\. • Partnered with product and design on UX iteration, and with QA on tight release feedback loops\.

Senior Software Engineer at Azilen Technologies, Jan 2024 \- Jul 2025 · 1 yr 7 mos, Ahmedabad, Gujarat, India, \- Led frontend architecture for scalable SaaS platforms using React\.js, React Native, and TypeScript\. \- Mentored a team of 5\+ developers and conducted regular code reviews\. \- Improved app performance by 40% by optimizing rendering strategies and bundle size\. \- Integrated third\-party APIs and analytics tools, enhancing product capability and UX\.
