Most AI work stalls between demos and real data. I am an AI Engineer and Full Stack Developer who embeds with your team and ships AI agents for logistics, ecommerce, SaaS, healthcare and regulated firms. ◆ INDUSTRIES I SERVE AND WHAT USUALLY BREAKS ▸ LOGISTICS, MOVING & FIELD OPERATIONS Dispatch, job status and proof of delivery live in calls, WhatsApp and spreadsheets. As an AI Engineer, I build field ops apps, driver and dispatcher portals, inventory tracking, and AI voice and chat agents that log jobs without retyping. ▸ ECOMMERCE & DTC Order exceptions, supplier feeds, returns and catalog updates consume a headcount. I build Shopify integrations, inventory and supplier sync, and agents that clear exceptions and escalate what needs a person. ▸ SAAS & PRODUCT TEAMS The AI feature has been on the roadmap two quarters and nobody has bandwidth. As an AI Engineer, I ship it: RAG over your own data, semantic search, in-product copilots, and the backend and API integration underneath. ▸ MARKETING & CREATIVE AGENCIES Campaign setup, reporting and client onboarding repeat weekly. I build multi-client marketing automation, CRM sync across HubSpot and Salesforce, and reporting pipelines that scale. ▸ LEGAL, LENDING, INSURANCE & ACCOUNTING Institutional knowledge sits in documents nobody can search. I build document intelligence, RAG retrieval, structured extraction from contracts and statements, and approval routing. ▸ HEALTHCARE & PATIENT SUPPORT Intake, triage and follow-up are manual and time sensitive. I build ticket classification, summarization and routing with audit trails and human checkpoints. ◆ WHAT I BUILD ▸ FULL STACK DEVELOPMENT As a Full Stack Developer, I build web apps in Next.js, React, Node.js, Python, FastAPI, PostgreSQL and Supabase. Cross-platform mobile apps in Flutter and React Native, with AI built in. ▸ AI AGENTS & WORKFLOW AUTOMATION As an AI Engineer, I build AI chatbot development, ticket triage, lead qualification, CRM sync, invoice extraction, reconciliation and exception reporting across n8n, Make, Zapier, LangChain and MCP. ▸ DELIVERY CAPACITY Backlog features, internal copilots, data pipelines, and prototypes taken to production. ◆ HOW I WORK: FORWARD DEPLOYED, SPEC DRIVEN Embedded with your people, in your environment, shipping into your repo. ① DISCOVERY I map where hours, errors and revenue leak. ② SPEC FIRST Before code I write a versioned spec: scope, data contracts, acceptance criteria, failure paths, human checkpoints, and a cost ceiling. You approve it. It becomes the source of truth. ③ BUILD AGAINST THE SPEC As an AI Engineer, I use spec-driven development with Claude Code. Every agent ships with regression tests on prompts and outputs, LLM-as-judge evaluation on the cases that matter, and trace-level logging, so behavior is measured, not assumed. ④ HAND OVER Documented, monitored and maintainable by your team. Not a black box only I can open. The spec is why my estimates hold, and why you can stop at any milestone and still own something usable. ◆ HOW I HANDLE YOUR DATA ▪ Least privilege on every connection. Scoped OAuth and read-only production access unless a write is approved in the spec. ▪ PII and patient data minimized or redacted before it reaches a model. ▪ Encryption in transit and at rest, immutable audit logs on agent actions, and a human checkpoint on anything irreversible. ▪ Your data is not used to train models. Zero-retention API configuration where policy requires it. ▪ I am an engineer, not an attestation. If you need SOC 2 or HIPAA sign-off, I build to your controls and your auditor certifies, not me. I will flag early if a workflow needs a control I cannot provide. ◆ STACK ▪ Web: TypeScript, Python, Node.js, Next.js, React, FastAPI, PostgreSQL, Supabase ▪ Mobile: Flutter, Dart, React Native ▪ AI: Claude, OpenAI, Gemini, LangChain, LangGraph, RAG, MCP, pgvector ▪ Automation: n8n, Make, Zapier ▪ Systems: HubSpot, Salesforce, Zendesk, Airtable, Shopify, Stripe, Slack, Twilio ▪ Practice: spec-driven development, evals, regression testing, trace observability, token cost ceilings ◆ RECENT WORK ✓ As an AI Engineer, healthcare support: n8n, LangChain and Claude agent stack cut manual ticket handling by 70% ✓ Marketing agency: automation platform cut campaign setup time by 65% ✓ B2B sales: multi-agent CRM workflow took lead response from 4 hours to under 4 minutes ◆ PROBABLY NOT A FIT One-off zaps, demoware for a pitch deck, or "make it agentic" with no defined success metric. I will ask what you are measuring before I quote. Tell me the process costing you the most hours, or the feature stuck in your backlog. I will send back a short spec of what I would build first, what I would build conventionally, and what I would leave alone.

I’m an AI Infrastructure and MLOps Engineer who builds, deploys, and operates production-grade RAG systems, LLM applications, AI agents, and machine-learning APIs on AWS, Azure, and Google Cloud. My advantage is the combination of AI engineering, backend development, and DevOps. I don’t just connect an LLM to an application—I design the deployment pipeline, data flow, monitoring, evaluation, security controls, and cloud-cost strategy required to run it reliably. Selected results: Delivered a $6,000 Vertex AI pipeline using Python and Kubeflow Pipelines Built a production RAG system with reported 95% retrieval accuracy and approximately 40% lower Azure cost Deployed a scikit-learn model on AWS SageMaker with API Gateway and Lambda Connected an LLM to live ERP data through an MCP server Automated PostgreSQL and K3s deployment on on-premises infrastructure using Ansible Migrated 17+ microservices to cloud-native infrastructure and reduced deployment time by 50% Supported systems processing 500K+ daily transactions with reported 99.95% uptime Reduced cloud infrastructure costs by approximately 30% while maintaining performance What I build: Production RAG and LLM systems RAG pipelines for enterprise documents and private knowledge bases Document ingestion, chunking, embeddings, and metadata filtering PostgreSQL pgvector, Supabase, Pinecone, and Azure AI Search Hybrid and semantic search Source citations and retrieval-quality evaluation Hallucination controls and prompt-injection protection OpenAI and Azure OpenAI integrations AI agents and business integrations LangGraph and LangChain workflows Tool calling and function calling MCP servers ERP, CRM, database, and REST API integrations Human-in-the-loop approval workflows Permission-controlled actions and audit logging Real-time backend services using WebSockets MLOps and LLMOps AWS SageMaker, Vertex AI, and Azure Machine Learning Model serving and production inference APIs MLflow and model versioning CI/CD for ML and LLM applications Evaluation datasets and regression testing LLM tracing, monitoring, latency, token usage, and cost tracking Drift detection, rollback, and production incident response Cloud and DevOps AWS, Azure, and Google Cloud Docker, Kubernetes, K3s, ECS, and EKS Terraform and Ansible GitHub Actions, Jenkins, and AWS CodePipeline FastAPI, Python, PostgreSQL, Redis, and REST APIs Prometheus, Grafana, CloudWatch, and Datadog Secure networking, secrets management, backups, and disaster recovery I work best with founders, CTOs, and engineering teams that need to move from an AI prototype to a dependable product, or that need senior infrastructure support without hiring a full-time AI platform team. I can help with a focused deployment, production hardening, architecture review, or end-to-end AI platform build. I begin by defining measurable success criteria for quality, latency, uptime, security, and cost. If your RAG, agent, or machine-learning system needs to become production-ready, send me your current architecture, target users, and biggest reliability or cost concern.
