Khoa Nguyen.
I'm Khoa — a digital marketer based in Hội An, Vietnam. I help brands find customers and grow online, and I'm a little unusual in how I do it: I don't just set the strategy, I build the systems that run it. Marketing fused with engineering — I write the code, build the agents, measure the ROI, and cut whatever doesn't earn its place.
What I do
- SEO & GEO. Classic search optimisation, plus Generative Engine Optimisation — getting brands surfaced inside AI answers (ChatGPT, Perplexity, Claude), not just on Google. It's an early-mover edge while most of the market still optimises for ten blue links only.
- Content that compounds. Content-led SEO where the writing actually moves the numbers — several pieces I've produced have become some of the fastest-growing pages on the sites I work on.
- AI content pipelines. I build production pipelines in Python that generate product imagery and video at catalog scale — wired straight into the store's data, idempotent and credit-safe, in place of studio or agency cost. Prompt engineering for image and video models is part of the craft.
- Measure, then cut. I audit spend with real data — link profiles, campaign ROI, what the AI engines actually ingest — and I'm comfortable killing a channel that isn't delivering and moving the budget somewhere that is.
From studio to storefront
I can take a product from nothing to launched, and I run the whole chain myself:
- Studio & photography — set up and light the shoot, and photograph the product directly.
- Post-production — retouch and grade in Photoshop, Lightroom and Premiere Pro, with AI tools (Evoto, WeShop, Higgsfield) for lifestyle and volume imagery — wired through APIs and MCP to run at catalog scale.
- Storefront build — configure the product in Shopify end to end: pricing, variants and components, and descriptions written for GEO/SEO.
- Then optimise — recommend the changes that lift click-through (CTR) and conversion, and measure what actually moves.
How I work
Direct assessments, concrete numbers, clear next steps — over theory. I'd rather do a few right things for the right people than spread budget thin. The work in this portfolio is the proof: real builds, honestly framed, with the parts that aren't done yet labelled as such.
How I learn
Mostly self-taught, and unapologetically AI-first. I'd rather ask an AI the moment I need something than chase a certificate — you can reach about 90% of any field that way. The other 10% is the part that counts: judgment you only build by shipping, and by learning from people who've actually done the work.

Operations Associate · made-to-measure menswear (DTC, Shopify)
Reporting directly to the founder, I run the product line end to end — photography, retouching, product setup, data tracking, full-stack SEO/GEO, and content — for a 7-figure Shopify store growing about 20% a year.
- Grew the luxury collection into the store's lead line — now about 60% of revenue.
- Doubled organic search traffic (2×) and replaced the SEO agency with in-house full-stack SEO — about US$3,000/month saved.
- Built an in-house content pipeline — studio photography plus AI imagery and video at catalog scale — in place of studio and agency cost.
- Got products surfacing inside AI answers (ChatGPT, Perplexity), not just Google — an early-mover GEO play.
- Run the line solo, shoot to storefront: photography, retouching, Shopify setup, tracking, SEO and content.
