I build production AI systems — RAG pipelines, LLM agents, and the multi-tenant SaaS they run inside. 14+ years of engineering, now focused on shipping AI features that actually hold up in production, not demos. Recent work: - An AI-Powered Knowledge Assistant with a custom RAG pipeline on AWS — retrieval, embeddings, and grounded answers over a client's private document set. - EnergyArray — a multi-tenant SaaS platform now in production at Tier-1 North American utilities, with secure per-tenant data isolation, real-time ingestion, and AI-assisted features. Stack: Java/Spring, React, PostgreSQL, AWS. What I do for clients: - RAG systems — chunking, embeddings, vector search (OpenSearch/pgvector), evals, anti-hallucination grounding - LLM agents — tool use, function calling, guardrails (OpenAI API or AWS Bedrock, your choice) - Multi-tenant SaaS architecture — data isolation, per-tenant config, billing telemetry - AWS-native delivery — ECS, Lambda, S3, OpenSearch; data stays in your VPC when compliance demands it How I work: - Fixed-scope feasibility audits when you need to know which AI use case will pay off before committing a quarter - Multi-week build engagements with a small senior team - Direct, written, no-fluff communication. I run discovery before I estimate. Best fit: teams adding AI to a real product — SaaS companies, data-heavy startups, and B2B vendors who need it to work in production, not just look good in a pitch. If you're building RAG or agentic AI on AWS and want it done right the first time, send a message — happy to do a 20-minute call.

I help businesses automate operations with AI agents, workflow automation, and API integrations. I build reliable systems for lead routing, CRM updates, internal copilots, RAG bots, and multi-step automations using Zapier, Make, n8n, Python, and custom APIs. My focus is not just building the workflow, but making it stable, measurable, and easy to operate after handoff. What we build end-to-end AI lead-routing workflow CRM automation with webhooks and retries RAG/internal knowledge bot API integration / synchronization system How I run delivery Clear scope → fast prototype → measurable outcomes (time saved, error rate down, cycle time down). I document everything, add tests/evals for reliability, and set up production-grade observability (logs, cost/latency, failure monitoring) so your team can confidently operate it after handoff. Deliverables you’ll actually receive Solution blueprint + architecture diagram (agent graph, tools, data stores) Prompt library + guardrails + regression/evaluation suite RAG pipeline with a vector database and citations where needed Automations/integrations with error handling, retries, and clear documentation Handover docs + training (async walkthrough available) If you share your top 1–2 workflows, I’ll map the quickest, safest path to automate them and propose a build plan with clear success metrics.
