focus: Building automations & integrations that go live in days, not monthsI build practical automation and integration solutions - connecting CRMs, ops platforms, AI services, and databases into workflows that just run. I work in n8n, Python, and TypeScript, design REST/webhook/OAuth integrations, and put LLMs to work on real business processes (content generation, document tailoring, support triage, semantic dedup). I care about systems that don't block, don't lose state, and degrade gracefully when an upstream API misbehaves.
"Automate what a computer should do, surface what a human needs to see."
A thin Next.js app talking to a 6-webhook n8n backend over signed (x-webhook-secret) calls. Long-running work - scraping, LLM scoring, resume tailoring, PDF rendering - runs asynchronously in n8n while the app polls Postgres for completion, so the UI never blocks or loses state. Integrates JSearch, RSS feeds, NewsData.io, Groq, PDFShift, and Gmail; defensive LLM-JSON parsing degrades visibly instead of breaking.

A 37-node n8n pipeline that runs every 6 hours (or on demand): scans 4 trend sources, dedupes and ranks, selects a topic with an LLM + brand-safety gate, researches it via parallel Google Search queries, writes a 1,500-2,500 word SEO article, generates a cover image, publishes via an authenticated REST API, emails subscribers, and logs every run. Fully autonomous, $0/month infra.

Retrieval → reranking → confidence-gated generation, with per-claim citations and an explicit refusal path instead of hallucinated answers. Measured against the live system, not a local mock: 100% retrieval accuracy (25/25) and 100% prompt-injection resistance (12/12) on its eval suite, with a documented before/after threshold tuning pass.

Paste a failed n8n execution and get a plain-English diagnosis of which node broke and why, instead of reading raw execution JSON by hand. Can auto-install its own error-monitoring workflow onto a connected n8n instance via a narrowly-scoped, disclosed write-access model.

💪 Se7en - AI-Coached Fitness App (RAG)
An offline-first React Native app whose AI coach uses retrieval-augmented generation: HuggingFace embeddings stored in Neon pgvector, retrieved per query and fed to Groq Llama 3.3 70B. Typed schema, custom chart library, state machines over booleans.

A 35-node n8n workflow that turns resolved support tickets into reviewed KB articles: webhook intake → conversation extraction → LLM-drafted article + summary → human review in Airtable → auto-publish to Help Scout Docs API → Slack notify. Uses Gemini embeddings + Pinecone for semantic de-duplication so it never publishes redundant articles.

- ⚡ Ship fast, ship live - I scope, build, and deploy solutions that go into production in days, not quarters.
- 🔌 Integration-first - REST, webhooks, OAuth, and signed server-to-server callbacks; I make systems talk to each other reliably.
- 🛡️ Resilient by design - async orchestration, defensive parsing, auth & secrets handling, and graceful failure over silent breakage.
- 📝 Documented & adoptable - I leave behind clear docs so the next person (or client) can run and extend the work.
Built with caffeine, curiosity, and a habit of automating the boring parts ☕⚙️
