I build and migrate CRMs that stop leaking deals — 9+ years across HubSpot, Salesforce, Method CRM, and integrated marketing stacks. Certified by HubSpot Academy (Marketing & CRM, 2021) and Shopify Partners (Developer, 2022). My focus: HubSpot migrations, AI×CRM workflows, and Shopify app builds for B2B SaaS and DTC operators who want their tech stack to actually run their business. How I work: (1) audit your current CRM and integration setup — what's broken, what's missing, what's redundant. (2) map a 30/60/90-day migration plan with clean lifecycle stages, deal pipelines, and lead scoring rules. (3) build the integrations — HubSpot ↔ Salesforce, Shopify ↔ HubSpot, Stripe webhooks, custom API connectors, n8n and Make com automation. (4) ship with documentation and a dashboard that proves the work. Done = HubSpot deal-velocity report, GA4 event attribution, and a Looker Studio panel that survives the next handoff. Stack: HubSpot Operations Hub, Salesforce, Shopify, Klaviyo, Kit (ConvertKit), Stripe, n8n, Make com, Zapier, Python (FastAPI), Node.js, OpenAI API, LangChain, Pinecone. Recent wins on Upwork: $4,000 Method CRM → HubSpot migration strategy with custom-object mapping and lifecycle automation across Sales and Marketing pipelines. $4,000 Shopify app shipped end-to-end (llms.txt generator, JSON-LD schema, AI FAQ generator, AI feed). $1,000 Kit (ConvertKit) hands-on training for a marketing team to run their own list. If your sales team manually copies deal data from emails into spreadsheets, your CRM lifecycle stages are inconsistent, or your AI integration ideas are stuck on whiteboards — that is the work I do. Send me a brief for your CRM migration, marketing automation rebuild, or AI×CRM integration project, whether it is a 2-week sprint or a multi-month rebuild. What is the single workflow eating most of your team's week right now?

I provide an AI Agent builder and AI Developer team that ships AI Workflow Automation and AI Chatbot products into production. We have delivered 200+ products across SaaS, marketplaces, AI tooling and internal platforms over 12+ years, and many of those clients have stayed with us for 3 - 10+ years. My job is to match each client with the right AI Agent builder and AI Developer engineers and stay accountable for every AI Agent builder engagement at production standard, not just a demo. Why hire my AI Agent builder team: - 200+ products shipped, now focused on AI Agent builder, AI Workflow Automation and AI Chatbot work - 12+ years of delivery, 100% JSS, Top Rated Plus - long-term clients who now bring us their AI agent and automation roadmap We work in two modes. AI-Accelerated: we run Claude, ChatGPT and Gemini across the cycle from PRD to test, which makes delivery roughly 40% faster. AI-Driven: my AI Agent builder team ships AI-powered products with full product discipline, with AI built in, not bolted on. Most of our work is AI Agent builder work, and the hard part is never the demo. A real AI Agent builder project is an ai agent that holds up in production: it handles edge cases, retries and fallbacks, keeps model cost under control, and passes safety evaluation before anything reaches a user. My AI Agent builder team treats an ai agent as full-stack software, with real state, memory, tool use, model routing, prompt versioning and the ai agent automation around it. We often take over an agentic ai developer hand-off when a solo builder cannot carry their ai agent to production. When a deterministic answer is the right one, we say so and put an Airtable workflow or a plain query behind the agent instead of another model call. AI Workflow Automation is the other half of most AI Agent builder briefs. My team builds AI Workflow Automation that removes manual steps end to end: an ai automation developer maps the process, the AI Agent builder layer runs it, and we connect it to the tools a business already uses through Zapier, n8n or a direct API. When the automation produces content, it plugs into copy generation, midjourney workflows, an ai video generator and ai artist assets. We treat AI Workflow Automation as production software, with monitoring, retries, cost guard-rails and a human in the loop wherever a wrong action is expensive. When conversation is the product, my AI Agent builder team works as an AI Chatbot and ai chatbot developer crew. We replace a brittle Botpress or gpt-3 era bot with a production AI Chatbot: an openai api developer wires the model layer, a generative ai developer shapes the outputs, and the result works as a real deal closer for sales and support rather than a toy widget. Every AI Chatbot we ship covers intent handling, escalation, analytics and the same safety evaluation every AI Agent builder product gets. As an AI Developer team we carry the whole system, not just the prompt. My AI Developer team turns python developer, machine learning and data scientist work into something shippable: an ai backend developer and an ai data engineer own the data layer, while an ai engineer and a machine learning engineer own the model layer. Clients come to my AI Developer team when their web developer cannot carry the AI layer, or when they need ai prompt engineering, an ai llm developer or a retrieval (RAG) build on top of an existing codebase. Clients hire my AI Agent builder team for: - an AI Agent builder team for production ai agent systems, from PRD to launch - AI Workflow Automation across the tools they already run, on Zapier, n8n or a direct API - an AI Chatbot, or an ai chatbot developer, that closes deals instead of deflecting them - an agentic AI developer for a LangChain or RAG build - python developer, machine learning, data scientist and machine learning engineer pairings - copy, midjourney, an ai video generator and ai artist tooling for generated content - an Airtable backend, or an Airbnb-style marketplace with AI on top - an ai app developer or full stack developer when the AI needs a real interface Recent work by the AI Agent builder team: - B2B luxury marketplace.

Hi, I am one of the best freelancer for web scraping / crawling / automated data extraction solutions on Upwork. I am doing web scraping jobs only and completed over 500 jobs and served hundreds of clients. My prices are more than reasonable and affordable compared to the service quality you will get, so please do not hesitate to request a quote if you need an expert scraper / crawler. I am developing my own custom program for each website I am going to scrap / crawl. I'm not using a pre-built software so i can adapt my program to any format and any website easily. There is no exceptional case, i can scrape any website using any technology (captchas, ajax requests etc.). I can provide scraped data in whatever format you want: csv, excel, xml, mysql etc. I can also provide you the program i used to scrape that website. I am developing my programs in java and you may run them on windows, mac and linux/unix machines. Up to now I developed applications to extract data from well known e-commerce marketplaces, search engines, business and local directories, real estate listings and many other websites. The work on Upwork is my full time job and not a side gig, so I dedicate a lot of attention to my clients, available to respond throughout the day, and work full days to complete the projects as fast as possible. You won't regret choosing to work with me. Thanks Taras H

I love launching tech projects with no-code and AI. My differentiator is that I am not only a capable bubble developer, but also a bubble designer. I design intuitive UX and elegant UI that users trust and adopt. I’ve optimized my bubble developer profile for better visibility on Upwork, so you may notice intentional keyword repetition. I help non-technical founders launch MVPs and validate ideas fast. I create AI, Saas and ERP internal apps, and I also have experience with mobile and marketplace apps. I’m a bubble developer and web application developer focused on MVP development. Videos about MVP and AI development tools on my Youtube channel are attracting 10k views monthly. It helped me establish a powerful personal brand as a Bubble developer and gain recognition within the Bubble community. Working with me you will get a full-cycle experience: I help you to get from an idea to a well-designed, well-scoped, production-ready, bug-free MVP. Personal traits: ✔️Excellent communication. ✔️Resourcefulness. ✔️Proactiveness and leadership. I build startup MVP ( SaaS MVP products ) as a Bubble No Code / Bubble MVP specialist from minimum viable product to a production-ready bubble .io MVP. I can take it end-to-end as a Full stack developer, keeping scope tight, UX clean, and delivery predictable. My methodology of building fast involves utilizing a templated framework of pre-built components, Bubble .io Canvas. It’s not universal for all projects, but being a bubble designer, I can customize its components in Figma. I am proficient in the Bubble .io API, and I was able to build a near-real-time integration with QuickBooks, synchronizing thousands of data rows between the systems. I’m a SaaS developer with experience scaling complex backend logic and data models. I build production-ready Nocode SaaS and MVPs fast. As a Bubble Developer ( No code Developer ), I design clean data models, scalable workflows, error handling and measurable funnels so your no code app can grow past the first users into a stable bubble .io SaaS. I'm in love with vibe-coding and AI App Development using platforms like Bubble .io, Lovable.dev, Replit and similar. For AI-driven features and rapid experiments, I use Lovable AI ( lovable.dev ), replit, copilot to move faster while keeping the build maintainable — including no code automation with OpenAI for intelligent features. For ultra-fast iteration and stakeholder demos, I also use Bolt.new, Base44, Anything, and Figma Make. As a Certified Bubble .io developer, I specialize in shipping a bubble .io mvp fast — from initial flows and data structure to polished UI and integrations — so you can validate your idea with a real product, not just a concept. As an MVP Developer, I can deliver a SaaS MVP ( AI MVP ) that’s clean, scoped and ready for real users. Bubble .io API + Stripe webhooks, API integration, and other api integration patterns are a core part of my builds. I ship marketplaces, AI, SaaS and ERP internal apps, including ai mvp and custom ai (LLMs and workflow automation). Working with me you get: ✔️Product thinking with a software product manager mindset. ✔️Clean UX flows + polished UI, plus bubble prototype iterations. ✔️Reliable delivery, QA, and basic devops setup. Additional experience: building no-code automations with Make, Zapier, and n8n, including AI-driven automation workflows. 🧠Personal passions: Vibe-coding, Agentic AI, LLMs, startup, gym, skiing. 🧠Favorite podcasts: All-In pod, Lightcone by YC, Training data by Sequoia Capital. 🧠Fun facts: I lived in San Francisco for 5 months in 2024-2025, but returned back to Europe. As a bubble developer, I’m also available for: app developer work, web developer support and mvp developer engagements. Becoming a Bubble developer truly changed my life and I am happy to work with promising founders helping them ship fast.
