Upgrade your workflow.Grow with a team that stays.
Westsandtec is a Hong Kong-based technology partner. Since 2018 we have built and operated websites, custom systems, and the ongoing operations behind them for businesses in Hong Kong. We build AI products of our own too — PixCode, a unified AI gateway.
Working ground
E-commerce stores, ERP and CRM rollouts, internal systems, and the ongoing operations that keep them running — we build on platforms your team can keep using long after launch.
Capabilities
From the websites and storefronts your customers see, to the systems that run the business behind them — we build what fits how your team actually works.
Web Development
Websites built and launched end-to-end — design, development, deployment, and the handover that lets your team take it from there.
System Development
Custom internal systems and apps built around how your business actually works.
Managed IT
Hosting, SSL, monitoring, backups, and incident response for the sites and systems we have shipped — or for ones you have inherited.
SEO & Content
Ongoing technical SEO and content production for steady, defensible growth. We maintain rankings rather than promising them.
Calculated
Chaos.
We start with discovery, ship in iterations, and stay involved past launch. Most projects move through four phases, with the timeline shaped around your scope rather than a fixed template.
Hong Kong-based. At this since 2018.
We build and operate the websites, custom systems, and AI products our clients put in front of their customers and teams. We stay involved long after launch, and we bring real AI capability into the businesses we partner with.
The longer story — what we stand for, what we deliver, how we partner.
Read more about usHow we work
Since 2018, we have helped growing companies automate workflows, replace manual operations, and scale on tools their teams can actually keep using.
We stick around
Most of our work has been built and operated with the same clients for years, not delivered and walked away from. The relationship is the project.
Your language, not ours
We work across languages — in conversations, in documentation, and in ongoing support. Talk to us in whichever language fits your team best, and nothing gets lost in translation.
Built around your workflow
We design systems that fit how your team actually works, rather than asking the business to bend around the software. WordPress, NetSuite, custom CRMs — we pick what fits, not what is fashionable.
AI you can actually use
AI capability for your business and your customers, not a buzzword on our pitch deck. PixCode is the public proof of how we approach AI delivery.
PixCode
One gateway.
Every AI model.
Most teams want to put AI inside their business but stall at the integration tax: separate accounts, separate keys, separate bills, and a different SDK for every vendor. PixCode is one API for OpenAI, Claude, Gemini, and the open models — billed once, switchable any time. It is in development now.
We are building and will operate it ourselves. It is how we work on AI in the open — the same capability we put into the businesses we partner with, in a form your team can actually use.
100+ LLMs through one billed-once pipeline — every mainstream model, open source or closed, accessed through official, properly authorised channels.
