Ours: 1 - Sales managers are 1st level, software analysts. They clarify your needs. You get 3 results: what users can do - user stories, recommended technologies, and estimate based on previous projects. 2 - Analysts clarify details and draw wireframes. They are mockups of all the pages with clickable buttons. So you can play with your app before it’s developed and make changes for cheap. Based on wireframes, we calculate project time and price estimation. 3 - Designers draw clickable graphic design prototypes. 4 - A team of developers, test engineers, and a project manager develops the product. 5 - The team installs it on your server and helps with app store submission. We do maintenance - part-time work on minor improvements after launch. Write to discuss and estimate your project. We give user stories and recommend technologies for free after a call. Without a call, we can’t do it well, unfortunately. All the right questions in writing would have taken days and still much missed. Answer the same workday. On weekends we rest, but if you have a chance - respond too. So please write to us now :)

    🤖 Senior Chatbot Developer & Conversation Designer | 6+ years of experience | Top Rated Plus | Expert Vetted #Chatbots #GPT4 #LLMs #Rasa #VoiceFlow #DialogFlow #Landbot #ManyChat # LangChain #OpenAI # RAG #VoiceBots #GenerativeAI #BlantAI #AirAI #Vapi #Prompt Engineering #Conversation Analysis ==== Hi, my name is Lena, a Senior Chatbot Developer & Conversation Designer. I help companies build smart AI Assistants that are user-friendly and engaging. I work together with a team of developers together designing and developing AI Assistants from start to finish so if you are looking for a partner you can trust AI side of your business you are in the right place. I'm a multi-disciplinary expert, I studied and did research in Linguistics and Artificial Intelligence. I have over 6 years of experience building chatbots using Rasa, VoiceFlow, DialogFlow, LandBot, and GPT-4, offering consultations on chatbot development and conversation design, and also teaching people to build chatbots themselves, giving mentoring sessions and workshops. ==== ✅ What makes me different from other freelancers: ▣ Full-cycle chatbot development services: from a business idea to production. ▣ Business-oriented approach: I think about chatbots as a tool to solve a specific problem. I try to design chatbots with your business goals in mind and the problem you are trying to help your users solve. ▣ User-centric: I believe that for any software project, including developing chatbots, it's very important to always keep users in mind. This means that I try to do user research before the beginning of the project and validate my assumptions as soon as possible on real users. ▣ Multidisciplinary: I am not just a full-stack developer. I have a background in Natural Language Processing and Artificial Intelligence and I understand Machine Learning and the mechanisms behind how chatbots actually work. ▣ A linguist by education: My first education is in Linguistics and I understand how language works. This helps me design conversations that sound natural and are user-friendly. ▣ I value transparent and direct communication. ▣ I value your time and I value my time and I prefer to deliver results quickly rather than doing work for the sake of work. ▣ Based on the reviews, people think I'm a nice person to work with :) ==== ✅ How I can help: ▣ Getting started with your chatbot project: I can share with you my knowledge and expertise in the area of Chatbot Development, help you come up with a project plan, give you an overview of available chatbot tools that would best suit your project and will help you reach your business goals. ▣ Full-cycle chatbot development: I offer full-cycle chatbot development services, from start to finish. For chatbot development I use GPT-4, Rasa, DialogFlow, ManyChat, Landbot and VoiceFlow. For backend I use Python. For frontend I use JavaScript (TypeScript). ▣ Conversation design: I can both help you create conversation flows for your chatbot from scratch and review your existing conversation design and give you suggestions for improvement. ▣ Audit of your existing chatbot: I can give you tips both on how to improve your implementation (why your Machine Learning doesn't deliver results) as well as your conversation design (why users don't enjoy talking with your chatbot). ▣ Workshops & training sessions: If you'd like to become a better chatbot developer yourself or are looking for a mentor to improve your current skills, I can help you. I also offer interractive workshops on the topic of chatbot development and conversation design for bigger teams, tailored to your specific use-cases. ▣ Chatbot widget: I also offer help with creating custom chatbot widgets for your website. ==== ✅ Tech Stack: ▣ Programming Languages: Python, JavaScript, TypeScript ▣ Chatbots: DialogFlow, Rasa, ManyChat, GPT3, VoiceFlow, Landbot, LangChain ▣ Database: MYSQL, Postgres, MongoDB, BigQuery, LanceDB, vector databases ▣ Machine Learning: Scikit-Learn, Tensorflow ▣ NLP: NLTK, Gensim, SpaCy, FastText, word2vec, MUSE, Whisper ▣ Crawling: Scrapy, Beautiful Soup, LXML ▣ Web: Flask, HTML, CSS, JavaScript, TypeScript, Framer ▣ Generative AI: ChatGPT, GPT-3.5, GPT-4, LLMs, LangChain ▣ Semantic search ▣ Deployment: Docker, AWS ▣ Integrations: mobile apps, web apps, Telegram, WhatsApp, Slack, Facebook Messenger, Instagram and others ▣ LLMs, RAG & Finetuning ==== ✅ Featured projects: ▣ Business Assistant Chatbot (GPT3, DialogFlow) ▣ Property Management Chatbot (GPT chatbot) ▣ Mental Health Chatbot (GPT chatbot) ▣ Language Learning Chatbot (Rasa) ▣ Financial Assistant Chatbot (DialogFlow) ▣ Health Coach Chatbot (DialogFlow) ▣ Chatbot-Recruiter (ManyChat) ▣ Voice Auto Attendant Chatbot (DialogFlow) For more see my portfolio below. ==== If this all sounds interesting, feel free to get in touch and we can schedule a free discovery call!
