Jonathan S.

Full-Stack & AI Lead | RAG, Agents, Automation | 2x CTO | AI-Augmented

I've spent 15+ years architecting production systems - from AI persona agent to global livestreaming services and cybersecurity analytics at 𝐂𝐢𝐬𝐜𝐨. Two 𝐂𝐓𝐎 roles and a Director of Engineering gave me the architectural perspective that only comes from owning the entire technical surface of a company. As Granum's first Lead AI Engineer, I'm building GenAI infrastructure with a focus on agentic AI automations - powering intelligent workflows across Granum's unified software ecosystem.

I use tools like Claude, Cursor, and Copilot daily and actively coach teams to do the same - writing better prompts, building with AI-in-the-loop, and shipping faster without sacrificing quality. ➤ What I build • Full-stack AI products - End-to-end design and development of AI-powered applications: AI chatbots and virtual assistants, RAG-based knowledge portals, financial document processing and compliance analysis, healthcare clinical note summarization and intake automation, legal contract review and clause extraction, real estate listing generation and market analysis, e-commerce product enrichment and recommendation engines. • AI automation & workflows - LLM-driven pipelines that replace manual processes: document analysis, report generation, data extraction, email summarization, intelligent routing • Multi-agent systems - Autonomous agents that plan, reason, use tools, and collaborate to complete complex tasks (research, analysis, content generation, data pipelines) • RAG-powered knowledge systems - Production RAG with vector search, hybrid retrieval, reranking, and domain-specific chunking strategies for accurate, grounded responses • Conversational AI & assistants - Custom chatbots, copilots, and AI assistants with memory, tool use, and guardrails - deployed into Slack, web apps, and internal tools ➤ Track record • Lead AI Engineer, Granum: Building GenAI infra and agentic AI automations for landscaping and arborist businesses across Granum's unified ecosystem (LMN, SingleOps, Greenius) • CTO, Asha.ai: I led the transformation of an experimental prototype into a robust platform for building lifelike AI personas. I architected core systems including vector search, retrieval-augmented generation, and tone-aware response modeling. I also built and now lead a small, fast-moving team that ships meaningful features such as proactive outreach, personality calibration, and memory-based interaction—all designed to preserve human connection and personal legacy at scale. • CTO, Driift Live: Designed the architecture behind a globally available ticketed livestreaming and e-commerce service. Transformed the platform from B2C to B2B2C SaaS while dramatically reducing infrastructure costs. • Director of Engineering, Dreamstage: Built the e-commerce and livestreaming platform from the ground up for ticketed events, contributing directly as an engineer while growing the org. • Software Engineer, Thuuz Sports: Led development of a React + Django platform where TensorFlow models detected actions in live sporting events and generated highlight clips in real time. • Software Engineer, Cisco: Led the front-end architecture for Secure Malware Analytics (formerly ThreatGRID), rebuilding the UI in React post-acquisition. ➤ Tech Stack • LLM / Agents / Automation OpenAI, Anthropic Claude, Google Gemini, open-source (Llama, Mistral) Orchestration & Agents - LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, ChatGPT App, MCP, tool-calling / function-calling patterns, multi-agent orchestration, agent memory and planning RAG & Knowledge - Cloud vector stores, chunking strategies, hybrid search, reranking, knowledge graphs, memory systems, personality modeling, tone-aware retrieval Automation & Workflows - n8n, Zapier • Full-Stack Frontend - React, Next.js, TypeScript, Tailwind CSS Backend- Python, Django, FastAPI, Nest.js, C# / .NET, Java / Spring Boot Database - PostgreSQL, Redis, MongoDB, Supabase, SQL Server • Cloud & Infrastructure Azure - Azure Functions, App Service, Blob Storage, Azure OpenAI Service, AI Search, Cognitive Services, Azure ML, Synapse Analytics, Data Factory, Databricks AWS - Lambda, ECS/Fargate, S3, SQS, RDS, , Bedrock, SageMaker, Redshift GCP - Cloud Run, Cloud Functions, Cloud Storage, BigQuery, Vertex AI, Gemini API, Document AI, AutoML, Pub/Sub DevOps - Docker, Terraform, GitHub Actions, CI/CD pipelines • AI-Assisted Dev - Cursor, Claude Code, GitHub Copilot, Windsurf • Low-Code Platform - 𝐂𝐥𝐚𝐫𝐢𝐬 𝐅𝐢𝐥𝐞𝐌𝐚𝐤𝐞𝐫 (10+ products, custom apps, relational database, scripting, Web Direct) Let's talk!
