🏆 Top Rated Plus | 100% Job Success | 5 Star Reviews ⭐⭐⭐⭐⭐ I'm Uttam — a CRM & Automation Architect and full-stack developer with 15 years of building systems that solve real business problems, not prototypes that gather dust. I work with funded startups, agencies, and enterprise teams to eliminate manual workflows, connect disconnected platforms like HubSpot, Salesforce, Zoho, and Odoo, and layer AI-driven automation into the operations that actually move revenue. ✔ CRM Implementation & Integration ───────────────────────────────────── HubSpot | Salesforce | Zoho | Odoo | SharePoint | Microsoft Power Platform I architect end-to-end CRM implementations and integrations, from pipeline design and custom object configuration to REST/GraphQL API connections with your accounting, time-tracking, eCommerce, and marketing platforms. I've integrated HubSpot with PostGrid for direct mail, Zoho with ATS and billing systems, Salesforce with custom internal tools, and Shopify storefronts with CRM backends for B2B pricing and order sync. The result every time: your team sees one source of truth instead of five tabs. ✔ AI-Powered CRM & Workflow Automation ───────────────────────────────────── This is where I spend most of my time, and where the market has the fewest people who can do it well. I architect and build AI-powered CRM systems across HubSpot, Salesforce, Zoho, and Odoo, then connect them to intelligent automation layers using n8n, Make, Zapier, and Power Automate. I don't just configure tools, I redesign the workflows underneath them so your team stops doing work the system should be doing. On the AI side: I build production-grade RAG pipelines, AI Agents, and document intelligence systems using OpenAI GPT-4o, Claude (Anthropic), LangChain, Pinecone, and Milvus. If you need an internal AI copilot that searches your company knowledge base, generates first-draft proposals from uploaded RFPs, or qualifies leads from incoming documents, I've built and shipped exactly that, embedded directly into client operations. I also run AI strategy and enablement sessions for business teams who want to understand what's worth automating, what's overhyped, and how to build a practical roadmap, without wasting budget on the wrong tools. ✔ CMS, eCommerce & Custom Web ───────────────────────────────────── WordPress | Shopify | HubSpot CMS | Sitefinity | Drupal | Webflow | Contentful | Magento I build and migrate enterprise CMS platforms for clients in healthcare, finance, legal, and education, including Sitefinity implementations, Drupal-to-latest upgrades, and HubSpot CMS custom module development. On the eCommerce side, I've built custom WooCommerce gateways, Shopify B2B stores with multi-tier pricing, and Magento B2B search ───────────────────────────────────── Specializations and Keywords: AI Automation, AI Agent Development, RAG Pipeline, LangChain, OpenAI GPT-4, ChatGPT Integration, Generative AI, LLM Integration, Prompt Engineering, N8N Automation, Make, Zapier Expert, Power Automate, Microsoft Power Platform, REST API Integration, GraphQL API, Workflow Automation, Business Process Automation, CRM Development, CRM Integration, CRM Consultant, HubSpot Developer, HubSpot Expert, HubSpot CRM, HubSpot Consultant, HubSpot Integration, HubSpot Automation, HubSpot CMS Developer, Salesforce Developer, Salesforce Consultant, Salesforce Integration, Salesforce Implementation, Zoho CRM, Zoho Developer, Zoho Integration, Zoho Consultant, Odoo Developer, Odoo CRM, Odoo ERP, SharePoint Integration, Microsoft 365, WordPress Developer, WordPress Expert, WordPress Plugin Development, Drupal Developer, Sitecore Developer, Webflow Developer, Contentful Developer, Headless CMS, CMS Migration, Shopify Developer, Shopify Expert, Shopify Integration, Magento Developer, WooCommerce Developer, eCommerce Automation, React Developer, Vue.js Developer, Node.js Developer, Laravel Developer, PHP Developer, .NET Developer, Full Stack Developer, SaaS Development, Multi-tenant SaaS, MVP Development, Custom Web Application, Healthcare CRM, Enterprise CMS, Digital Transformation, Solution Architect, Technical Architect, Fractional CTO, Drupal, Sitecore, Craft CMS, Umbraco, Sitefinity, Kentico, Contentful, Bigcommerce, Sanity, Strapi, Storyblok, Headless

I help small businesses, SaaS teams, and agencies reach real WCAG compliance by combining deep front end knowledge with accurate manual testing. As a specialist who can fix issues when appropriate and guide developers when needed, I make the path from issue to solution clearer, faster, and more reliable. I have supported accessibility work for high traffic, high profile sites including Honda, Acura, AMPM, and ARCO where speed, accuracy, and technical judgment were essential to meeting release deadlines. Cleaning up outdated components and nonsemantic patterns also produced clear performance gains and measurable SEO improvements reported directly by client teams. ► HERE IS HOW I SUPPORT CLIENTS ◄ • WCAG accessibility audits and actionable findings • Manual testing with screen readers and keyboard only • Accessibility remediation and component level improvements • Design and pattern review using the APG (accessibility patterns for interactive UI) • Developer guidance for accessible fixes and best practices My work has helped teams resolve time sensitive accessibility requirements connected to litigation, reduce user flow blockers, clean up code and components across large websites, and ship updates on schedule. I work in a steady, collaborative way that keeps teams informed and focused on meaningful progress. I enjoy making complex issues easier to understand and improving access for real users. If you would like help with an audit, remediation, or a specific accessibility issue, reach out and I can take a look at your site and let you know the first things I notice.
