As a Top 1% Expert Vetted consultant with 15 years of experience, I architect Revenue Operations (RevOps) and Go To Market (GTM) data ecosystems that drive predictable, scalable growth. I bridge the gap between high level business strategy and deep technical data architecture. Currently, enterprise software is undergoing a massive shift. Companies are rapidly trying to deploy AI and automated workflows, but they are hitting a wall because their underlying CRM and GTM data is messy, siloed, or poorly integrated. I solve that. I do not just set up software; I design and deploy autonomous revenue engines and build custom AI agents. I specialize in unifying complex MarTech stacks, establishing pristine data pipelines, and orchestrating platforms like Salesforce and HubSpot to work as a single, AI ready ecosystem. Core Consulting Pillars: • GTM Data Architecture & CDP Implementation: Breaking down silos between Sales, Marketing, and Customer Success to create a unified, reliable customer data pipeline (Snowflake, Data Cloud, CDPs). • AI Agent Development & Orchestration: Extensive experience building, training, and deploying custom AI agents tailored to your specific sales funnels. I restructure legacy CRMs and prepare enterprise data architectures so internal AI agents and predictive models can operate securely and without hallucinations. • Enterprise MarTech & RevOps Strategy: Designing multi system integrations, automated pipeline velocity models, and full funnel attribution frameworks that tie marketing spend directly to closed won revenue. The Tech Stack I Architect & Oversee: • Enterprise CRM & RevOps: Salesforce (Sales, Marketing & Data Cloud), HubSpot (All Hubs), Microsoft Dynamics 365. • Data & Automation Ecosystems: Complex GTM automation and secure multi system integrations leveraging advanced middleware (n8n, Make, native API architecture) and data warehousing. • AI & Predictive Modeling: Custom AI agent development, Applied GenAI integration, predictive lead scoring, and automated customer lifecycle management. The Agency Advantage: In addition to my individual consulting, I lead a top tier GTM architecture agency based in the Bay Area. We are official, certified partners with both Salesforce and HubSpot. This means when you hire me for strategic architecture, you also have the option to tap into my dedicated engineering and execution team to seamlessly build out the blueprints we design right here through Upwork. My approach is strictly pragmatic and outcome driven. I partner with B2B and B2C organizations, from high growth startups to global enterprises, that need a seasoned architect to future proof their revenue operations. Let’s connect through Upwork to audit your current architecture and map out your GTM growth strategy.
