I am a Senior Next.js Developer focused on React, Node.js, and API-driven web applications. My main work is building custom web products where the frontend depends on clean architecture, reliable API integration, authentication, and real user workflows. I usually work on Next.js / React applications connected to existing backends, Node.js services, REST or GraphQL APIs, Firebase, CMS tools, and third-party integrations. I can help when you need a React developer or front-end developer who can do more than just build UI screens. I can take Figma designs, Bootstrap themes, existing prototypes, or legacy interfaces and turn them into production-ready Next.js / React pages connected to real data and backend logic. I also support full-stack Next.js and MERN-stack products when the project uses React, Node.js, Express.js, MongoDB, or a similar JavaScript-based stack. My backend work usually covers API integration, authentication flows, account logic, dashboards, ecommerce flows, admin panels, and integration with external services. Earlier in my career, I worked with WordPress, CMS-based websites, and classic web development projects. That experience helped me understand content structure, SEO-friendly pages, admin workflows, landing pages, and business websites. Today, my focus is custom development: Next.js applications, React frontends, full-stack Next.js products, SaaS platforms, ecommerce flows, marketplaces, customer portals, and web applications built around real product logic. Typical projects I can help with: - Next.js and React web application development - full-stack Next.js development with Node.js and Express.js - React developer / front-end developer work for existing products - REST API and GraphQL API integration - Firebase, Firestore, and Google Cloud Platform integrations - NextAuth and custom authentication flows - SaaS dashboards, customer portals, marketplaces, and ecommerce platforms - Strapi, headless CMS, and CMS-driven web products - Figma-to-Next.js or Bootstrap-to-Next.js implementation - frontend architecture, performance improvements, and code maintainability Tech I work with: Next.js, React, TypeScript, JavaScript, Node.js, Express.js, NestJS, MongoDB, PostgreSQL, RESTful API, GraphQL, Firebase, Firestore, Google Cloud Platform, NextAuth, Redux, Strapi, CMS integrations. I am comfortable joining an existing team, working directly with a CTO or founder, taking ownership of a product area, and moving features from backlog to release.

I build AI-powered automation systems, RAG applications, full-stack AI SaaS products, and real-time WebRTC & FFmpeg media platforms using JavaScript, Python, Node.js, Next.js, React, Electron, OpenAI, Claude, and modern AI development tools. If you need an AI app that connects to your data, automates workflows, processes video, audio, integrates with your existing SaaS tools, or turns manual operations into reliable software, I can help you design, build, and ship it. 𝐌𝐲 𝐬𝐭𝐫𝐨𝐧𝐠𝐞𝐬𝐭 𝐚𝐫𝐞𝐚𝐬 𝐚𝐫𝐞: • AI automation systems for business workflows, internal tools, CRMs, documents, reports, and data operations • RAG applications using private documents, databases, PDFs, APIs, vector search, and LLMs • Full-stack AI SaaS platforms using Next.js, React, Node.js, Python, FastAPI, PostgreSQL, Supabase, MongoDB, Redis, and APIs • Claude, OpenAI, Gemini, Whisper, ElevenLabs, LangChain-style workflows, prompt pipelines, and AI-assisted product features • WebRTC and LiveKit applications for video calling, voice chat, real-time communication, screen sharing, and recording • FFmpeg pipelines for video processing, clipping, transcoding, streaming, audio extraction, thumbnails, and AI-powered media workflows • Electron desktop applications for AI document automation, email automation, local file workflows, and cross-platform business tools • Browser automation and workflow automation using Puppeteer, Playwright, Apify, n8n, APIs, Airtable, Google Sheets, and CRMs • Cursor-assisted development for faster implementation while maintaining clean architecture, secure code, and production quality I am not a generic AI prompt engineer. I am a senior full-stack engineer who builds real AI-powered software: backend systems, APIs, automations, RAG pipelines, dashboards, desktop apps, media pipelines, and production-ready SaaS platforms.

Need an AI web app or SaaS MVP shipped fast, without rework later? I build production software that stays easy to change as load grows. Clean React fronts. Dependable Node.js APIs. RAG that answers from your data. I'm Shweta Dubey, a Senior Full-Stack AI Engineer with 8.3+ years. I've taken products from sketch to launch. HyROI and a custom timesheet platform went from ideas to deployed systems under my lead. I handled UX flows, the React front end, secure API contracts, and the data layer. On the front end I ship fast, accessible React with TypeScript. Reusable components and sane state. Server data fetching where it helps performance. On the backend I build Node.js REST services with clear contracts. Pagination, auth, rate limits, and query tuning baked in. Optional GraphQL when it adds value. For AI features I integrate OpenAI with LangChain. Chat assistants and document Q&A. Summarization as needed. RAG over PDFs and internal wikis so answers are grounded. I set up embeddings and retrieval, plus eval dashboards so you can watch outputs and improve them. Multi tenant setups supported, tenant data stays isolated. Infra stays predictable on AWS with Docker. Kubernetes when the workload calls for it. Data on PostgreSQL or MongoDB with migrations and tuning. CI/CD from repo to production. What I can help with: - SaaS MVPs in React and Node.js, with auth and billing. Dashboards and settings, role based access. - AI chat and Q&A using OpenAI plus LangChain. RAG over PDFs and Google Drive. Internal KB support. - Backend REST APIs. Versioned endpoints, pagination, rate limits, caching, webhooks. - Internal tools and admin portals in React with TypeScript. - Data modeling and performance tuning on PostgreSQL or MongoDB. - CI/CD pipelines to AWS with Docker and Kubernetes. Observability, alerts, logs. How I work: - Discovery call and scope, then a clear plan. - Prototype or API spec in 48 to 72 hours. - Milestones with weekly demos and progress notes. - Clean Git history. Small PRs with review checks. - Testing matched to risk, API tests and unit tests where they pay off. - Handover docs and runbooks. Short video walkthrough. - Jira for tracking, async updates as needed. I work 25 to 30 hours per week, IST. US and EU overlap, plus UK hours where needed. Open to a 3 to 5 day pilot.
