The 2-second version: Recent wins: consolidated ~$2M+/month in revenue reporting across 50+ studios for a national fitness brand (AFR Fast 100 #2); AI triage engine processing 100-130 enquiries/day at 97% accuracy, saving ~8 hrs/week per admin; quote population compressed from 20-40 min to under 30 sec for a Sydney Trains authority. 10 production systems shipped across healthcare, glazing, rail safety, fitness franchising, e-commerce, travel, and creative agencies. Portfolio and live examples ready — send me an invitation. --- The longer, sit-down version: Hi I'm Vanh, an automation engineer and full-stack developer. I spent the last year at Syncstream, an AI agency in Australia, delivering for clients across construction, rail, fitness, and travel. Before that I freelanced on Upwork — healthcare staffing, e-commerce, creative agencies. I also build and ship my own products, including a freight invoice audit SaaS and a published Claude Code plugin. What I deliver: Lead Gen and CRM Automation — scraping, enrichment, scoring, CRM sync (HubSpot, Pipedrive). Dedupe, SLAs, dashboards, and automated follow-up sequences that survive server restarts. Operations and Data-Entry Automation — form-to-sheet-to-database flows, approvals, reconciliation. Multi-platform sync so your tools talk to each other. No more copy-paste between your CRM, proposals, jobs, and spreadsheets. AI-Powered Systems — LLM-based triage and classification, AI content engines with cited research, AI audit pipelines, and browser automation for platforms with no API. I use Claude Code daily, build MCP servers, and have a published plugin on the marketplace. Full-Stack Development — production SaaS platforms with multi-tenant architecture, role-based access, and async job pipelines (Next.js, TypeScript, Supabase, BullMQ). Selected outcomes: - Fitstop (150+ studios, $60M+ network revenue): consolidated ~$2M+/month in revenue reporting across 13 regions and 50+ studios. Eliminated monthly manual reporting using AI browser automation against a platform with no API — handling OTP login and reading metrics off the screen across every location. - Greater Glass (~$4M/yr commercial glazing): AI triage engine processing 100-130 enquiries/day at 97% accuracy. 240-300 deals auto-categorised/month. Six pipeline stages automated end-to-end. ~8 hrs/week saved per admin. - RailSafe, Sydney Trains (~$4.5M/yr): compressed quote population from 20-40 min to under 30 sec with AI matching products across inconsistent naming. 87+ products managed by automated pricing sync with full audit trail. - SailPalma (premium Mallorca tours): ~7% positive reply rate on cold B2B outreach — 7x the agreed benchmark — off 5,000+ verified leads. - Sifter (my own SaaS): solo-built freight invoice audit platform. 9-stage AI pipeline, multi-channel invoice ingestion, carrier dispute workflow. How we'll work: 1. Rapid discovery — define success metrics, map your stack. 2. Blueprint — flows, schema, error handling, the decisions that keep it running. 3.

I'm the founder of a UK travel-tech company that distributes tours through Viator, GetYourGuide, and Bokun. I built our entire stack myself — channel manager integrations, inventory APIs, AI customer support, and the server infrastructure it runs on. I take on client projects where that operator experience is the difference between "done" and "done right." WHERE I'M STRONGEST: ► OTA & Channel Manager APIs I've mapped products between Bokun and Ventrata (OCTO standard), debugged failed Viator-Bokun API connections, built bulk repricing automation for Viator supplier portals, and managed listings across Viator, GetYourGuide, and Klook. If your availability isn't syncing, your rates don't map, or you need a custom Inventory API connecting a third-party system to an OTA — I've almost certainly hit your exact problem in my own business. ► AI-Integrated Operations I run a production AI helpdesk: tickets triaged by AI, routed to human agents when needed, with full handoff logging. I connect AI to real business systems — Airtable, CRMs, email, messaging platforms — via API. Working systems, not demos. ► Self-Hosted Systems & Infrastructure I host and maintain my company's full stack — n8n, CRM, helpdesk, bots, file delivery — on hardened Linux servers with Tailscale zero-trust networking. I do the same for clients who want off the SaaS treadmill: SuiteCRM, FreeScout, and similar open-source alternatives, deployed with backups, monitoring, and security hardening. WHY HIRE A FOUNDER INSTEAD OF A FREELANCER: I think in business outcomes, not tickets. I'll tell you when the cheap option is good enough and when it will cost you more later. English + Vietnamese. GMT+7 — I cover the hours US/EU teams are asleep. Fixed-price preferred for defined scope; retainer for ongoing management.
