E-commerce automation and AI operations engineer, technology lead and Shopify developer|
I build Shopify stores, WordPress sites, and workflow automations that replace the manual steps your team repeats every week. Based in Manila, Philippines, working worldwide.
How I work: one point of contact from first call to launch. I turn your goals into a written scope, track the work in Jira or Notion, and send a short update at every milestone so you always know where things stand.

FAQ
Common Questions
How does pricing work?
No fixed packages. After a short call about what you need, I send a written scope with a fixed price or an hourly estimate, so you know the cost before any work starts.
You're in Manila. Will our hours overlap?
Yes. I work weekdays 9am to 6pm Manila time (UTC+8), which covers most of the Australian workday. For the UK or the US I take early-morning or evening calls by arrangement. We pick a time that suits you.
How do we get started?
Send an email or use the form below. I reply within 24 hours (Mon–Fri, Manila time), then we schedule a call to go over the project.
Which tools do you work with?
Shopify, WordPress and WooCommerce for sites and stores. Zapier, n8n and Python for automation, with Airtable and Google Sheets as data layers. Cin7 Core for inventory and pricing sync.
Do you offer support after launch?
Yes. I can stay on for fixes, small changes and monitoring of automations, either as needed or on a monthly arrangement.
What do you need from me?
Admin or collaborator access to the platforms involved, your brand assets and content, and one person who can answer questions and sign off on each milestone.
"Before Nick, I was going through the motions. He gave me real ownership — Shopify
builds, automation pipelines, critical releases — and never once questioned whether
I could handle it. That environment made me want to go further. I started
building tools on my own initiative, just because I finally felt like my work
mattered. That's what a great leader does — not push you forward, but make you
want to move yourself."
— Jonathan Tubay

ProblemA leather footwear brand closing its doors needed its US store to clear the last Barefoot line: every colour and size, one final sale, no restock.
ResultRevamped Shopify storefront built around the final sale: a 3D wireframe hero, one-tap colour picks with sale prices, and clear closing-down messaging across the store.
A full visual revamp of the Sapmok USA Shopify store for its closing-down sale. The brand has since closed and the store is offline; the screenshots show the final design.

ResultRuns on a GitHub Actions schedule. Reads its project list from Airtable. Alerts via Slack; email reports go out on demand from the dashboard.
Automated status checker that runs Playwright health checks on a cron schedule via GitHub Actions, logs results to Airtable, and fires Slack + email alerts on failures.
ProblemOps work — QC, monitoring, automations — needed a reliable 24/7 assistant that could actually execute, not just chat.
ResultCustom AI agent deployed on cloud VPS. Handles QC for 2,000+ active SKUs, runs cron automations, connects via Slack/Telegram/desktop. Runs unattended with a watchdog + auto-failover.
E.D.I.T.H. — Every Detail Inspected, Totally Helpful. The always-on AI agent watching over operations. Built on Nous Research's Hermes Agent framework and deployed on a DigitalOcean VPS in Singapore (now run by SentryX), she handles SKU quality control, scheduled price checks, cron automations, and operational monitoring across multiple client projects. Connects via Slack, Telegram, and desktop — runs unattended with a watchdog process and automatic failover.
ProblemPrivate, boring-but-critical ops work — payroll extraction, invoicing, classification — shouldn't rack up per-token cloud costs.
ResultThe Hammer of Results. Local workhorse on Qwen3.6-27B — no per-token API cost, private, workload-sufficient. Runs payroll, invoicing, extraction & drafting lanes.
T.H.O.R. (Thunder-Heavy Operations Runner — The Hammer of Results) is the on-prem workhorse. An open-weight model runs on an on-prem GPU box (now run by SentryX) rather than a paid API, so client data never leaves the machine and there is no per-token API cost. (Qwen3.6-27B-NVFP4 served via vLLM on an EdgeXpert box, for the technically inclined.) Local brain, same "measure → verify → disclose" standard as E.D.I.T.H. — quiet, verify-first, and lands real outcomes.
ProblemI wanted one assistant that runs my PC by voice and follows me to my phone, without paying per token.
ResultA Jarvis-style HUD on my desktop and phone. Her own wake word, voice control of apps and files, reminders, notes and a daily briefing, routed across free cloud models with an offline fallback.
A.L.I.S.O.N. (Adaptive Learning Intelligent System for Operational Neural assistance) is my own desktop assistant. A small router hands the model only the tools that fit each message, and deterministic "arms" do the real work, so a free model only has to choose, never calculate. She listens for a wake word I trained myself, opens and closes apps, handles files, volume and screenshots, turns screenshots into todos and notes, and asks for a yes before anything risky. Every change starts from a snapshot, so it can be rolled back in one command. On my phone she runs as a sign-in web app. She also talks to Caelia, so alerts land on my desk when I am at the PC and on my phone when I am not.
ProblemMy family needed one place for reminders, todos, expenses and quick answers, in the languages we speak at home.
ResultA Telegram assistant with 18 skills: research with sources, reminders, a shared family todo board and expense log, receipt and voice-note reading, translation, PDF summaries and a 7 AM briefing.
Caelia lives on Telegram and only answers family and friends I invite, each with a private notebook. She runs on a small server with her own agent runtime on Node 22 and a failover chain of free models, picked after benchmarking 13 of them. Voice notes are transcribed with Whisper, and she translates between English, Tagalog, Cebuano and Aklanon. A separate watchdog bot sends the alerts and reminders, a Cloudflare Worker checks the server is alive, and she links to A.L.I.S.O.N. on my PC. 137 unit tests cover the bridge and the skills.
The chat in the picture is an example, not real family data.
ProblemExisting Squarespace site had no store — paintings couldn't be sold. Tablet layout was broken due to Squarespace's mobile-first approach.
ResultStore enabled with Prodigi print-on-demand for multiple sizes & materials. Tablet responsive fixed with custom CSS & JS.
Took over an existing artist portfolio on Squarespace, enabled eCommerce, and integrated Prodigi as a print-on-demand provider — allowing paintings to be sold in various sizes and print formats. Also resolved the tablet responsive breakpoint using custom CSS and JavaScript, since Squarespace's mobile-first philosophy had left the mid-screen layout unstyled.
