Experience
Frontend Engineer
Relative Technologies (C SQUAD LLP)
Remote, Hyderabad
Contributed to frontend development across three production Web3 and DeFi platforms, relative.fi (P2P betting platform for crypto and real-world assets), RFX (DeFi trading platform built on Hyperliquid), and Reflex (AI-powered trading terminal with sentiment signals).
- Architected server-side rendering in a Web3 environment, resolving hydration mismatches between server-rendered markup and browser-only wallet state (MetaMask), thereby improving SEO indexability and initial load performance.
- Built core trading and betting interfaces from scratch, contributing to a launch that scaled to $25M in trading volume and 70K+ active users within 60 days.
- Developed complex UIs, including real-time order books, live betting markets, AI-driven sentiment dashboards, and interactive charting, translating intricate product requirements into responsive, accessible interfaces.
- Integrated WebSocket connections to stream live market data, order updates, and odds changes, with reconnection handling and message batching to keep UIs smooth under high-frequency updates.
- Cut production incidents by ~90% by instrumenting Sentry, triaging recurring error patterns, and shipping fixes upstream into shared components, materially improving stability and user trust.
- Mentored junior engineers and conducted code reviews, improving code quality, TypeScript adoption, and consistency in async/data-fetching patterns.

Projects
Full-Stack Travel Management Platform
Admin | Backend | Frontend
Engineered a scalable backend using Node.js, TypeScript, MongoDB, Redis, and AWS S3, featuring real-time WebSocket communication. Implemented a RAG pipeline for natural-language product search, embedding product data with Gemini on upload, storing vectors in Pinecone, and answering user queries by retrieving top matches and grounding responses with Gemini Flash. Built a complex admin SPA with React and Vite for internal data management, and a high-performance public site with Next.js for optimal SEO and speed. Implemented end-to-end security with JWT and Arcjet, and fully automated the deployment process with a CI/CD pipeline using GitHub Actions.
Product Upload Tool - Chrome Extension
GitHub
Built a Chrome Extension (Manifest V3) that automated product upload for a tour company, extracting tour data from Google Sheets and Docs via OAuth and auto-filling a complex Angular admin panel, handling Angular change detection, ng-select dropdowns, and Quill rich-text editor inputs. Wrote a resilient parser to extract structured data from non-uniform, unlabelled Google Docs, handling a wide range of edge cases and inconsistent formatting across thousands of documents. Backed the extension with a Cloudflare Worker for license key validation (24-hour caching) and shipped a Side Panel UI with code obfuscation for production delivery. Reduced product upload time by ~60% for employees, replacing hours of repetitive manual data entry across the company's product catalog.
