What we do

Intelligent software, end to end.

AI automation, agents, full-stack builds, and consulting — one senior engineer across all of it.

AI Automation

Custom workflow automation with n8n, Make, and Zapier — connecting your tools, cleaning your data, and removing the manual work that slows your team down. From lead sourcing to reporting, built to run reliably and observably in production.

  • n8n / Make / Zapier workflow design & self-hosting
  • Lead sourcing & enrichment (Apify, Google Maps, scraping)
  • CRM, email & Google Workspace automations
  • API & webhook integrations between any tools

AI & Automation

From prototype to production AI.

I build AI systems that ship — not demos. Grounded retrieval, evaluated prompts, guarded outputs, and monitoring so your team can trust what it puts in front of users.

01

Ingest & ground

Connect your data, build retrieval, and give models the right context.

02

Orchestrate agents

Tool-using workflows and n8n automations that do real work end to end.

03

Evaluate & guard

Eval suites, guardrails, and monitoring before anything reaches users.

AI Automation

LeadPipe — automated lead engine

An end-to-end lead pipeline: scrape Google Maps businesses with Apify, dedupe and store in Supabase, then run a 3-step email outreach sequence with merge fields, daily cron follow-ups, and a dry-run safety mode.

  • Apify → Supabase → SendGrid pipeline
  • Automated 3-step outreach with merge fields
  • Daily cron follow-ups & CSV export

AI Automation

AI sourcing agent (n8n + OpenAI)

Rescued and completed a half-built, tangled n8n flow into a reliable AI sourcing agent connecting OpenAI, Apify, and Google Sheets — the client had nearly given up before the handover.

  • OpenAI + Apify + n8n + Google Sheets
  • Untangled and shipped a stalled workflow
  • 5.0★ — “brought the project home”

AI Agents

  • Streaming LLM chat (Vercel AI SDK)

  • Tool-using research agent
