A lean team that cares deeply

Engineering
Digital Excellence

We're not an agency. We're a small crew of dedicated engineers who take on a handful of projects and give each one our full attention — from architecture to launch and beyond.

  • You talk directly to the engineers building it
  • Never more than 4 active projects — ever
  • Zero handoffs, zero account managers

What We Bring

Everything your
product needs

We don't subcontract or spin up a team overnight. Every service is delivered personally by the same small crew that knows your product inside out.

Mobile Applications

Flutter, React Native, Swift. We build the whole thing — UI, backend, push notifications, app store submission. Handed off running, not just built.

Web Platforms

Next.js storefronts, SaaS dashboards, and marketing sites that are fast by design, not by accident. We architect for scale from day one.

AI & Automation

LLM integrations, AI-powered product features, and intelligent workflow automation. We build AI that holds up in production — not demos that break the moment real users arrive.

Cloud Infrastructure

AWS, GCP, Azure — we pick the right tool for your problem. Serverless, containerised, or bare metal. We run it, monitor it, and own it.

Identity & SSO

We manage authentication across your entire product surface. Secure token services, social auth, and our own SSO backbone for cross-product identity.

Security & Compliance

We take data protection seriously on every project we touch. Encryption, access control, audits, and compliance baked in — not bolted on.

Our Work

Built by us.
Still run by us.

We don't build and disappear. Every product below is something we actively maintain, monitor, and improve.

Technology

Chosen for reliability and longevity — not trend.

Who We Are

Small crew.
Full ownership.

Sinlung Tech isn't an agency. We're a handpicked team of engineers who obsess over the products we build. We cap active projects deliberately — because quality demands attention, and attention doesn't scale infinitely.

When you work with us, you're not handed to a project manager. You talk to the people writing your code. We own the architecture, the deployment, the monitoring — and we're accountable for all of it.

Every product we build runs on our managed infrastructure, benefiting from security practices and operational tooling we've refined across every engagement.
