What you’ll do

Ship working systems: Design, build, and maintain services, scripts, and workflows with clear SLAs.
Automate everything: Orchestrate workflows (n8n/Make/Zapier/custom) across CRM, APIs, comms channels, and backends.
Build agentic apps: LangChain/LangGraph-based tools for enrichment, routing, triage, and outreach—with evals, guardrails, retries, and cost controls.
Scrape responsibly: Headless browsers + official APIs; rotating proxies, backoff, and anti-bot patterns (always within ToS/legal).
Connect data: Stand up light ETL/ELT to Postgres/BigQuery; implement RAG/search over internal docs; ensure freshness and observability.
Make it reliable: Logging, metrics, alerts, dashboards, and business-hours on-call for what you ship.
Document & hand off: Clear runbooks, diagrams, READMEs so others can extend your work.

AI outreach bot: Segment-based, personalized first touches + follow-ups; dedupe against CRM; A/B prompt + template testing.
Scrape → Clean → Sync: Playwright job to capture public business data, normalize, and sync to Postgres/Sheets with change detection + alerts.
