We're a fintech/financial-analytics company building an AI assistant that lets users ask natural-language questions about markets — mutual funds, equities, ETFs, REITs, government securities, macro forecasts, portfolio optimization, and financial calculators — and get back rich, interactive answers (charts, tables, comparison cards, forms) instead of plain text. The backend NLU/LLM engine and data APIs already exist. We need a skilled front-end developer to design and build a polished, production-grade chatbot web app that consumes these APIs, and to make it embeddable into our main marketing website. What You'll Build 1. A responsive, modern conversational chat interface (message stream, typing/loading states, streaming responses, session history). 2. A library of interactive "answer blocks" rendered inside chat bubbles — e.g. data tables, line/bar charts, comparison views, multi-step input forms, pickers, and result dashboards. Clarification / follow-up flows (the assistant asks the user to pick a sector, fund, company, etc. via inline UI components). 3. Clean API integration with our existing chat backend (REST/JSON). 4. An embeddable widget (e.g. a floating chat launcher / iframe or script embed) to drop the assistant into our website. 5. Smooth animations, theming (light/dark), and a refined UX. Preferred Tech Stack 1. React 19 + TypeScript + Vite 2. Tailwind CSS 3. Recharts (or similar) for data visualizations 4. Framer Motion for animations 5. Consuming a Node/Fastify JSON API (no backend work required, but API-integration experience essential) (Open to discussion if you have strong reasons to suggest alternatives.) Required Skills 1. Strong React + TypeScript, with real experience building component libraries and complex, state-heavy UIs. 2. Solid CSS/Tailwind and a strong eye for clean, modern UX. 3. Experience integrating with REST APIs (auth, loading/error states, streaming/SSE a plus). 4. Data-visualization experience (charts, tables, responsive layouts). 5. Ability to build a reusable, embeddable widget. Nice to Have 1. Prior work on chatbot / conversational UIs or AI assistant front-ends. 2. Familiarity with fintech / financial data presentation. 3. Experience with LLM-powered apps (streaming tokens, tool/function-call style responses). 4. Accessibility (a11y) and performance optimisation. Deliverables 1. Fully functional, responsive chatbot web app integrated with our APIs. 2. Reusable, documented component/block library. 3. Embeddable website widget. 4. Clean, documented, maintainable codebase + brief handover docs. To Apply Please share: Relevant portfolio pieces that you have worked on.

Hello there, I will build your fintech AI chatbot interface in React 19 + TypeScript + Vite, delivering the conversational message stream with streaming/SSE token rendering, the interactive answer block library (Recharts visualizations, comparison cards, data tables, multi-step forms), and the embeddable floating widget for your marketing site. On a similar finance chat UI, lazy loading answer blocks and virtualizing the message list kept interactions smooth even with 100+ messages in a session. I will apply the same approach here. Questions: 1) For the answer blocks, do you have a finalized list of response types the LLM returns, or will we define the component map together? 2) Do you have Figma mockups or brand guidelines, or will I handle the full UI design? Looking forward to talking through the details. Kamran

As a full-stack developer with substantial experience in designing conversational UIs and AI assistants, I am well-suited to create the polished and production-grade chatbot web app you need for your fintech advisory website. My skill set aligns perfectly with your listed tech preferences: React, TypeScript, Tailwind CSS, Recharts (or similar), and Framer Motion. Having built complex state-heavy UIs that integrate REST APIs before, I understand the importance of fluid API integration and ensuring clean error states and given that I have designed many frontend/backend chatbot systems faithful to them on top of securing your REST API. What sets me apart is my expertise with LLM-powered apps - streaming tokens and tool/function-call style responses, which will be invaluable for this project where users need interactive data responses. Additionally, my ability to optimize for performance isn't restricted to just code but also encompasses accessibility (a11y) a vital feature often overlooked in projects' development lifecycle. Needless to say I find the prospect of working within the Fintech sector exciting, and not one new to me: I have built several trading bots, worked on portfolio optimization and risk management tools using various financial datasets.

Dear Client, I read "Fintech Advisory Website Development" carefully and understand you need typing software with accurate speed and accuracy measurement. My hands-on experience with Website Design, Web Development, Chatbot aligns directly with what you need. I've built typing tests and tutors with real-time WPM/accuracy tracking, lesson progressions, leaderboards and detailed reports — precise keystroke handling is the part most get wrong, and I get it right. A few quick questions to get us started: 1. Is this a typing test/tutor for practice, or exam-style assessment (with admin reports)? 2. Web-based or a desktop application? 3. Do you need multiple languages or keyboard layouts (e.g. English, Hindi, stenography)? Thanks & Regards, Deepak

Hi, I’m Armin Nikdel. I can build the responsive chat interface and the interactive answer blocks you described, consuming your existing NLU and data APIs. I’ll focus on a clean message stream with typing indicators, streaming support, and session history, then embed it cleanly into your marketing site. Two concrete steps I’d take: first, I’ll prototype the chart and table renderers against sample API payloads to confirm they match your data shapes; second, I’ll test the embed flow on a staging page to ensure styles don’t leak between the host site and the widget. I typically deliver a project like this in about two weeks, with the scope you outlined, for INR 37500. That covers the chat shell, the block library (tables, charts, comparisons, forms), and the embeddable wrapper. One thing I’d need to clarify early: do you have a design system or brand guidelines I should follow for the chat widget’s look and feel, or should I propose a neutral, professional style that fits a fintech context?

Keen — a polished conversational chat front-end that consumes your existing NLU/LLM APIs is exactly my lane. New on Freelancer, not new to development; I run a live production WhatsApp AI assistant. Recent 5-star review: "quality exceeded my expectations." I'd build in React 19 + TypeScript + Vite + Tailwind: - Chat shell: message stream, typing/loading + streaming (SSE/chunked) responses, session history, light/dark theming, smooth animations. - A registry of interactive "answer blocks" — tables, line/bar charts, comparison cards, multi-step input forms, pickers, result dashboards — each keyed by a block type in your JSON. Since (per the board) you'll predefine a fixed block set, I'll build a typed `type → React component` registry so adding a block later is a one-file change, with graceful fallback for unknown types. - Inline clarification/follow-up flows (assistant asks user to pick sector/fund/company via inline components that post back). - Embeddable widget: a floating launcher (script embed + isolated iframe/shadow-DOM) so it drops into your marketing site without CSS bleed. Phased: chat shell + streaming → answer-block library → embeddable widget. Two questions: (1) can you share the API contract / sample JSON per block type (OpenAPI or examples)? (2) streaming transport — SSE, WebSocket, or chunked HTTP? Proof: techfinitymonster.com. I can start today.
