I build production-ready AI + RevOps systems around Salesforce/HubSpot— orchestration, fine-tuning, MCP/semantic layers, RAG, and custom apps—so your sales & marketing teams ship faster and close more. 15 years in GTM systems; expert-vetted; 100% JSS; enterprise-grade delivery. What I Do AI Orchestration & Agents: Workflow design, tool use, evaluation, guardrails. Model Work: Prompt libraries, fine-tuning, preference optimization, evals. MCP & Semantic Layer: Domain schemas, tool servers, retrieval interfaces. RAG over GTM Data: Vectorizing Salesforce/HubSpot, docs, tickets, logs. Custom Apps & Integrations: Node/TS, React, FastAPI; SFDC/HubSpot apps; data pipelines. Signature Offers (fixed-scope starters) RAG QuickStart (2–3 weeks) – Ingest SFDC/HubSpot + docs → eval’d RAG with dashboards and red-team tests. MCP + Semantic Layer Blueprint (10 days) – Define tools, schemas, safety, and a reference MCP server. RevOps AI Tune-Up (2 weeks) – Lead/opp hygiene, scoring, routing, SDR copilot prompts + analytics. Salesforce/HubSpot AI Add-Ons – Case summarization, auto-notes, email drafting, knowledge search. Fine-Tune Sprint – Data curation, SFT or adapter-based finetune, eval harness, rollback plan. Recent Wins (abridged) Sales SDR Copilot: triage + drafting on HubSpot → 35% faster replies, 12% lift in meeting creation. SFDC Knowledge RAG: MCP tools + policy guardrails → deflection up 18%, CSAT +0.4. Quote Assist: approvals + terms via LLM tools → cycle time −27%, fewer reworks. GenAI Data Layer: semantic layer on CRM + docs → GTM analytics in minutes, not days. Tech & Stack LLMs/AI: OpenAI, Anthropic, HF; RAG Semantic/MCP: Model Context Protocol, tool servers, function/tool calling Data: Postgres, ClickHouse, Redis, dbt, Snowflake, SQL, etc. Apps/Infra: Node/TS, React, Docker, GCP/AWS/Azure, any and all APIs CRM: Salesforce (Admin, App Builder, Sales/Service Cloud), HubSpot (RevOps/Automation) CRM App Dev: Custom and marketplace apps for Salesforce and HubSpot Who I’m Best For B2B SaaS, GTM-heavy orgs, public sector/regulated, field ops—teams with Salesforce/HubSpot that want measurable, production AI (not demos). How We Work Consultation (60–90 min): Objectives → success metrics → data/readiness check. Design Sprint: Architecture, safety/guardrails, eval plan. Pilot: Ship something that moves a KPI; then scale. Credentials / Certifications: MBA (Operations). Salesforce Data Architect, Admin, App Builder, Sales/Service Cloud. HubSpot Certified. (Full list on request.) Message me with: your CRM (SFDC/HubSpot), the GTM KPI to move, and target timeline. I’ll suggest a 2-week pilot that proves value fast.
