I build Make, n8n, Zapier, Notion, Sheets, GoHighLevel, HubSpot automations, and AI agents for teams buried in manual work.
Top-rated on Upwork, 100% job success.
Fifteen years running operations and supply chains before this, so I understand a process before I automate it.
Most of what I do falls into three buckets.
1. Automation systems
Make, n8n, and Zapier pipelines connecting CRMs, spreadsheets, inboxes, and internal tools. When no-code hits its ceiling, I drop into Python, JavaScript, or Google Apps Script. Typical work: AI email triage, document parsing, lead enrichment with Clay, CRM sync, reporting dashboards that update themselves.
2. Web apps and mobile apps
Full-stack builds in Node, React, and PHP with MySQL, MongoDB, or Supabase. Native mobile apps in React Native with Expo. Recent examples: SuppliMatch, a B2B sourcing platform that collects and compares co-packer offers from a single brand request, end-to-end automated. Namedrop, an AI business name generator with live domain availability, social handle checks, and USPTO trademark lookups. Truvex, a React Native app for restaurant shift callouts with phone auth, real-time sync, push and SMS notifications, and Stripe billing.
3. Ops and data tooling
Notion workspaces, Airtable systems, Google Sheets automations, and custom dashboards. Not just setup. Systems that teams actually use.
Some recent work:
• Replaced ~30 hours a week of manual supplier outreach with one Make scenario that sends briefs, parses replies, and updates a sourcing dashboard.
• Built a lead enrichment pipeline that pulls from LinkedIn and open data, scores leads with the OpenAI API, and routes them into HubSpot.
• Shipped Namedrop, checking domain availability across TLDs, USPTO trademark records, and X and TikTok handles in real time.
• Sold 20+ Notion templates used by founders and small ops teams.
Examples of the work, so you can see the shape of it:
- A broken Make, n8n or Zapier automation diagnosed and fixed
- A manual weekly report replaced with a pipeline that runs itself
- GoHighLevel wired to your CRM, sheets and inbox
- A lead enrichment and AI scoring pipeline feeding HubSpot
- An AI agent that reads a shared inbox and turns action items into tasks
- A full audit of a Box, Google Drive or SharePoint with every file mapped
- HubSpot data audited for duplicates, decay and pipeline leaks
- WhatsApp Business automated with replies, routing and CRM sync
- Every mention of a brand found across YouTube, Reddit, GitHub and Discord
- Invoices and documents read automatically into your accounting system
- Zapier workflows rebuilt in Make or n8n with nothing lost
- An assistant that answers questions from your own company documents
- Every CV parsed, scored against the brief and pushed into your ATS
- A monthly bookkeeping close prepared as draft entries for review
- Suppliers found, contacted in their language and tracked to a shortlist
Tools I use day to day:
Automation: Make, n8n, Zapier, Google Apps Script
Languages: JavaScript, TypeScript, Python, PHP, SQL
Frontend: React, HTML, CSS
Backend: Node.js, Express
Databases: Supabase, PostgreSQL, MySQL, MongoDB
Data and docs: Google Sheets, Excel, Airtable, Notion, Clay
AI: OpenAI API, Claude API, document parsing, extraction,
classification, content generation
CRMs and comms: HubSpot, GoHighLevel, Slack, Telegram, WhatsApp, Gmail, Outlook
Payments: Stripe, PayPal
How I work
I write more than I talk. If you prefer to kick off with a call, that is fine, but I will ask for a short written brief first so we both know what we are looking at. I give honest scope estimates, flag risks early, and tell you when something is not worth building.
If you have a manual process you want gone, or a tool you want built, send a message with two or three lines describing it. I will tell you whether I can help, how long it should take, and what it will cost.

Built your app with Lovable, Bolt, Cursor, v0, Replit Agent, or another AI coding tool?
Chances are you shipped fast but you’re not fully sure what might break once real users start clicking around.
That’s exactly where I help.
I’m a Software Engineer & QA specialist with 10+ 𝒚𝒆𝒂𝒓𝒔 𝒐𝒇 𝒆𝒙𝒑𝒆𝒓𝒊𝒆𝒏𝒄𝒆, including working at Broadcom as Sr MTS (ICB 4), testing and working on large-scale systems where quality and reliability actually matter.
Now I help founders and startups test AI-generated web apps before bugs become bad reviews, lost users, or embarrassing launch-day surprises.
I also built: 𝙏𝙝𝙚𝙑𝙞𝙗𝙚𝙏𝙚𝙨𝙩𝙚𝙧
Paste any URL and it crawls your app, generates real Playwright E2E tests, runs them in a real browser, and tells you what’s actually broken - usually in 𝒖𝒏𝒅𝒆𝒓 10 𝒎𝒊𝒏𝒖𝒕𝒆𝒔. You can even try it for 𝒇𝒓𝒆𝒆 before deciding to move forward.
The AI finds issues fast. I go deeper into the things automation usually misses — edge cases, UX problems, broken flows, accessibility issues, and launch-critical bugs.
If you’re shipping fast and want confidence before launch, send me your app URL or let’s book a quick call and test it properly.

I build automation systems that turn manual operations into reliable pipelines for B2B operators, marketing teams, and consultancies.
My focus is the intersection of n8n, GoHighLevel, and AI: lead generation workflows, CRM automation, AI agents (Claude, GPT, Vapi.ai voice agents), and the API plumbing that holds modern marketing operations together.
What I deliver:
🔹 n8n workflow architecture for lead routing, data enrichment, and multi-platform sync
🔹 GoHighLevel CRM setup, custom automations, sub-account configurations
🔹 AI-powered workflows with Claude API and OpenAI integrations: document classification, content generation pipelines
🔹 Voice agents on Vapi.ai connected to GoHighLevel, HubSpot, and custom CRMs
🔹 Webhook and REST API integrations between marketing tools, ad platforms, and operational systems
🔹 WordPress and WooCommerce custom development when automation crosses into web
Recent results:
✅ Real estate agency: automated multilingual listing pipeline through Google Sheets, DeepL translation, broadcast channels, and watermarked images. Replaced 2 to 3 hours of manual posting per listing.
✅ Consulting firm: Vapi.ai voice agent integrated with client CRM for inbound lead qualification and auto-tagging.
✅ Lead qualification system processing contacts in 10 seconds instead of 2 to 3 hours of manual review.
✅ WooCommerce automation handling 2,000+ SKUs through WP All Import and custom CSV transformations.
✅ Email classification and document processing pipeline with OpenRouter AI fallback for cost optimization.
Stack: n8n (self-hosted, 2+ years), GoHighLevel, Claude Code, OpenAI and Anthropic APIs, Vapi.ai, Supabase, JavaScript, Node.js, React, TypeScript, WordPress, Docker, Linux. Comfortable with REST APIs, webhooks, and integrating tools that don't have native connectors.
Why my background matters: 8+ years building web applications and 2 years running Google, Meta, and TikTok ad campaigns as a media buyer. I understand both the marketing funnel and the technical plumbing, which is a rare combination. I see automation gaps that pure devs miss and build solutions that pure marketers can't.
Availability: selective. Currently taking 1 to 2 additional contracts at 10 to 20 hours per week. I prefer retainer or longer engagements over one-off fixes.
How to work with me:
1. Send a message describing what you need to automate.
2. I respond within 4 hours with clarifying questions and rough scope.
3. We agree on scope, timeline, and deliverables before any work starts.
4. I build, document, and hand off with clean operational notes.
If you're looking for a $5 quick fix or template installation, I'm not the right fit. If you want production-grade automation that actually works at scale, let's talk.
