Hi, I'm Foxtails

Full-stack engineer · AI applications · GTM engineering

I build full-stack products and the automation behind revenue teams: LLM-powered features, lead and account data pipelines, and integrations that connect the tools a business already runs on.

Open to full-stack, AI engineering, and GTM engineering roles.

What I do

  • Full-stack products: TypeScript and React frontends, Node.js and Python APIs, SQL and document databases, from first prototype to production.
  • AI applications: LLM features on top of model APIs, including structured extraction, classification, summarization, retrieval (RAG) and tool-using agents, with evaluation and guardrails so they behave predictably.
  • GTM engineering: lead sourcing and enrichment, email finding and verification, CRM and outreach integrations, scraping, and workflow automation that turns manual prospect research into repeatable pipelines.

Stack

  • Languages: TypeScript, JavaScript, Python, PHP, SQL
  • Frontend: React, Redux, Vue / Nuxt, Material UI, Tailwind
  • Backend: Node.js / Express, Flask, Django, Laravel, REST and GraphQL APIs
  • Data: MySQL, MongoDB, pandas, NumPy
  • AI: LLM APIs, prompt and tool design, RAG, agents, evals
  • GTM & automation: enrichment APIs, CRM integrations, web scraping, Selenium, workflow automation

Selected work

Project Area What it shows
Hunter.io Python SDK GTM Typed client for email finding, domain search and verification (the building blocks of lead enrichment), with response caching and tests.
Scraping & automation GTM / data Queue-based profile scraping, GraphQL data collection, and browser automation for reporting tools that have no API.
Retail business software Full-stack Admin app for a print-on-demand catalog: one-click SKUs, variant pricing, trademark screening, and Shopify/Etsy listing data.
Statistics dashboard Full-stack / data React + Express app that runs Python (pandas, NumPy, SciPy) analysis jobs and charts the results.

Current focus

LLM-driven GTM workflows: account research, lead enrichment and qualification, and personalized outreach, built on solid API integrations and data pipelines.
